The value of Ex = - (Q/(4πε0)) *(x/r³), Ey = - (Q/(4πε0)) ×(y/r³), Ez= - (Q/(4πε0)) ×(z/r³) , for the potential due to a point charge Q at origin.

At infinite distance when an electric charge isn't under the influence of the point charge, the potential is defined as zero. Electric potential at a given position is the quantum of work that has to be done to bring the charge at a finite distance from the point charge.So, the electrostatic potential from a point), at a distance r is given by,

U = 1/4πε0Qr

Both theunit charge and the point charge are positive. So, the work has to be done against the electrostatic force. Therefore, the potential is positive. However, still, if the point charge had negative value, then in that case potential would have been negative.

A) To calculate Ex, we take the partial derivative of V with respect to x: Ex = - ∂V/∂x = - (Q/(4πε0)) × (x/r³)

B) To calculate Ey, we take the partial derivative of V with respect to y: Ey = - ∂V/∂y = - (Q/(4πε0)) × (y/r³)

C) To calculate Ez, we take the partial derivative of V with respect to z: Ez = - ∂V/∂z = - (Q/(4πε0)) × (z/r³)

D) To show that the results of parts (a), (b), (c) agrees with the equation for the electric field of a point charge, we can use the equation for the electric field of a point charge E→ = (Q/(4πε0r²)r^. We can see that, Ex = -(Q/(4πε0))×(x/r²) , Ey = -(Q/(4πε0))×(y/r²), Ez = -(Q/(4πε0))×(z/r²) which is equivalent to the formula for the electric field of a point charge E → = (Q/(4πε0r²)) ^r. So, the results of parts (a), (b), (c) agrees with the equation for the electric field of a point charge.

d = 18sin(πt/2)

This equation models the horizontal distance of the pendulum from the center as a function of time.

What is pendulum?

A pendulum is a weight suspended from a pivot so that it can swing freely. Pendulums are often used to regulate time in clocks, as well as for scientific experiments to study gravity and other forces.

The pendulum swings 18 inches from right to left in 2 seconds, so we can use the equation d = 18sin(πt/2). To explain this, note that the pendulum takes 2 seconds to swing from right to left and back to right.

This means that it takes a total of 4 seconds for the pendulum to complete one period. Therefore, we can divide the time by 4 seconds to find the period.

This gives us πt/2. We then multiply this period by 18, the horizontal distance of the pendulum from the center, to get the equation d = 18sin(πt/2).

Therefore, d = 18sin(πt/2)

The maximum Current is 19.57 ohm, as mentioned inside the paragraph preceding.

A circuit in electronics is a totally circular path that electricity passes through. A current source, wires, and a load are the components of a basic circuit. Any ongoing channel for the conveyance of energy, info, or a signal is referred to as a "circuit" in a wide sense.

Voltage across the left 10 ohm resistance is V = IR = 0.92A * 10 ohm = 9.2 V

Thus this is the voltage across the 15 ohm and R

Therefore the current in the 15 ohm = 9.2/15 = 0.61 A

Kirchoff's current law states that current in = current out

So, from the 10 ohm & 15 ohm resistors, 2A is entering, while 0.92 + 0.61 are exiting.

Let current from R resistance is I₁

So, 2A = 0.92 + 0.61 + I₁

To find the time it takes for the ball to reach its highest point, we can use the following kinematic equation: vf = vi + a*t= 2.02 seconds.

where

vf = final velocity (0 m/s, since the ball, is at its highest point)

vi = initial velocity (25.0 m/s, upward)

a = acceleration (9.8 m/s^2, downward)

t = time

Substituting in the given values, we get: 0 = 25.0 + (-9.8)t

Solving for t, we get: t = 25.0 / -9.8 = 2.55 seconds

x = vi*t + (1/2)at^2

where

x = distance fallen (2.0 m, the initial height)

vi = final velocity (0 m/s, since the ball is at its highest point)

a = acceleration (9.8 m/s^2, downward)

t = time

Substituting in the given values, we get:

The ladder is not long enough to reach the cat. The cat would not be rescued with the ladder available.

The term "displacement" refers to a shift in an object's position. It is a vector quantity with a magnitude and direction. An arrow pointing from the starting point to the finishing point serves as its symbol.

When an atom or group of atoms in a molecule are replaced by another atom, this is referred to as a displacement reaction. For instance, copper metal is displaced when iron is added to a solution of copper sulphate.

To determine if the cat can be rescued using the 95-foot ladder, we need to calculate the reach of the ladder, which is the distance from the base of the ladder to the highest point it can reach.

The ladder starts 8 feet above ground, so the reach of the ladder is 95 feet (the length of the ladder) + 8 feet (the distance above ground) = 103 feet.

Now, we need to calculate the horizontal distance between the base of the ladder and the tree. This distance is the sum of the distance between the fire truck and the tree (75 feet) and the distance between the base of the ladder and the fire truck (8 feet).

So, the horizontal distance between the base of the ladder and the tree is 75 feet + 8 feet = 83 feet.

Now we have to check the reach of the ladder is greater than the horizontal distance between the base of the ladder and the cat and the height of the cat.

103 feet (reach of ladder) > 83 feet (horizontal distance) + 60 feet (height of cat)

103 > 143

Ray tracing is a method used to determine the location and characteristics of the image created by a mirror.

To solve this problem, first draw a ray diagram to help visualize the situation. In this diagram, draw a line from the light bulb to the center of the mirror, which is the focal point. Then draw a ray that reflects off the mirror and back towards the focal point. This ray is called the principal ray.
Using the principal ray, you can draw a line that is parallel to the principal ray and intersects the focal point. This line will intersect the mirror at a point that is the same distance from the mirror as the light bulb is from the focal point. This is the location of the image.
To determine whether the image is upright or inverted, draw another ray from the light bulb, parallel to the principal ray. If this ray reflects off the mirror and intersects the focal point, then the image is upright, and if it reflects off the mirror and does not intersect the focal point, then the image is inverted. In this case, the image is inverted.
To determine if the image is real or virtual, draw a line from the image to the center of the mirror. If this line intersects the mirror, then the image is real, and if it does not intersect the mirror, then the image is virtual. In this case, the image is virtual.
To verify these results, you can calculate the location of the image using the mirror equation: 1/f = 1/d1 + 1/d2, where f is the focal length, d1 is the distance from the light bulb to the mirror, and d2 is the distance from the image to the mirror. Plugging in the values from this problem, we get 1/20 = 1/60 + 1/d2, which simplifies to d2 = 120 cm. This confirms that the image is 120 cm from the mirror, which is the same location as determined by ray tracing.

The ideal banking angle for a gentle turn of 1.90 km radius on a highway with a 105 km/h speed limit (about 65 mi/h) should be around 2.62 degrees.

What is banking angle?

Banking angle is an angle of a banked turn or curve on a road, track, or other surface. It is the angle at which the inside edge of the curve is raised above the surface, allowing the vehicle to turn more safely.

Banking angle is important to ensure vehicles can maintain traction while turning, as it helps to reduce the effect of centrifugal force on the vehicle and its passengers. Banking angle is also used to reduce the effects of gravity, which can cause the vehicle to lose control in a turn. Banking angle can range from 0° for a flat surface to a maximum of 60° for high speed curves.

105 km/h = 29.2 m/s

What is wavelength?

Wavelength is a concept in physics that describes the distance between repeating units of a wave, such as the distance between two crests of a water wave or two peaks of a light wave. It is a fundamental property of waves and is typically denoted by the Greek letter lambda (λ). The wavelength of a wave is inversely proportional to its frequency.

Part A

The energy of a photon can be calculated using the equation E = hf, where E is the energy, h is Planck's constant (h = 6.626 x 10^-34 J*s), and f is the frequency. To find the minimum frequency of a photon that can break a hydrogen bond, we can rearrange the equation to solve for f:

f = E / h

Given that 0.1 eV is required to break a hydrogen bond, we can convert this energy to joules by multiplying by the conversion factor 1 eV = 1.602 x 10^-19 J.

E = 0.1 eV * 1.602 x 10^-19 J/eV

E = 1.602 x 10^-20 J

Now we can substitute the value of E and h into the equation to find f:

f = 1.602 x 10^-20 J / (6.626 x 10^-34 J*s)

f = 2.41 x 10^14 Hz

So the minimum frequency of a photon that can accomplish this is 2.41 x 10^14 Hz.

Part B

The wavelength of a photon can be calculated using the equation c = fλ, where c is the speed of light, f is the frequency, and λ is the wavelength. To find the maximum wavelength of a photon that can accomplish this, we can rearrange the equation to solve for λ:

λ = c / f

Given that the minimum frequency of a photon that can accomplish this is 2.41 x 10^14 Hz and the speed of light is c = 3 x 10^8 m/s, we can substitute these values into the equation to find λ:

λ = 3 x 10^8 m/s / 2.41 x 10^14 Hz

λ = 0.1240 nm

So the maximum wavelength of a photon that can accomplish this is 0.1240 nm.

The car can take the curve without skidding at speeds up to 15.3 m/s.

Speeds refer to the rate of motion or operation of a machine, vehicle, or process. It can also refer to the rate of change of a variable. Speeds are often expressed in terms of the time it takes to travel a certain distance, the distance traveled in a certain amount of time, or the rate of rotation or revolution. Speeds can be measured in linear units such as meters per second or miles per hour, or in angular units such as revolutions per minute. Speed is an important factor in many activities, including transportation, sports, and manufacturing.

The maximum speed at which the car can take the curve without skidding to the outside of the curve is determined by the maximum static frictional force between the tires and the pavement, which is equal to the product of the normal force on the tires and the coefficient of static friction.
The normal force on the tires is equal to the weight of the car and can be calculated as follows:
Normal force = 1563 kg * 9.8 m/s2 = 15,319 N
The maximum static frictional force is then calculated as follows:
Maximum static frictional force = Normal force * coefficient of static friction = 15,319 N * 0.72 = 11,036 N
The maximum speed at which the car can take the curve without skidding is determined by the centripetal force of the car, which is equal to the product of the mass of the car, the speed of the car, and the radius of curvature of the road.
Therefore, the maximum speed of the car can be calculated as follows:
Maximum speed = sqrt(Maximum static frictional force/ Mass of car * Radius of curvature)
= sqrt(11,036 N / 1563 kg * 44 m)
= 15.3 m/s

According to the question, 1.132887kcal energy used by a 55.0-kg woman who does 50 deep knee bends in which her center of mass is lowered and raised 0.400 m.

People have figured out how to transform energy from one format to the next and then use it to accomplish tasks, making modern civilization possible.

As we know that-

Mass = 55kg

Knee bend = 55

Efficiency = 20%

Displacement = 0.4m

We will first determine the total Workdone.

Work done = 2n(mgh)

n = 55,

m = 55kg,

g = 9.8m/s²

h = 0.4m

Work done = 2 ×55 × 55 × 9.8 × 0.4

Work done = 23,716J

Considering that the lady completes 20% of her work efficiently;

so,

her energy = 20% of 23,716J

= 4,743.2

= 4.74KJ

Energy = 1.132887kcal

The distance has the car traveled during the 6 seconds is 90 m.

The rate during which velocity change is called acceleration. Acceleration usually indicates a change in speed, but not often. An object that pursues a circular route while keeping a constant speed is still moving forward because the vector of its motion is altering.

Given -

Mass m = 500kg

Initial velocity ,u = 0

Final velocity ,v = 30 m/s

Time , t = 6s

So, acceleration , a =?

By using first equation of motion = v= u+at

= 30 = 0+ a ×6

=30 = 0+6a

=6a = 30 = a = 30/6 = a = 5m/s^2

So, distance travelled = s= ?

By using second equation of motion = s = ut+ 1/2 at^2

= s = 0× 6+1/2×5×6×6

s = 0+90

s= 90 m

so the answer is = 90m
