Answer:

13.4225 g/cm³

Explanation:

Given that:

Linear expansivity α = 2 * 10^-5

Change in temperature dt = t2 - t1 = (150 - 25)°c = 125°c

Initial density (d1) = 13

New density d2 =?

Using the relation :

α = (d2 - d1) / d1 * dt

d2 - d1 = d1 * dt * α

d2 = d1 + d1*dt*α

d2 = d1(1 + d1*dt*α)

d2 = 13( 1 + (13*125*2*10^-5))

d2 = 13(1 + 0.0325)

d2 = 13(1.0325)

d2 = 13.4225

d2 = 13.4225 g/cm³

Answer: Electron

Explanation:A negatively charged particle found circling or orbiting an atomic nucleus. An electron, like a proton is a charged particle, although opposite in sign, but unlike a proton, an electron has negligible atomic mass. Electrons contribute no atomic mass units to the total atomic weight of an atom.

Answer:

true

Explanation:

i think it's true because I took a quiz on this

Explanation:

Type of charge on an object depends upon the material of the object. However, most of the material are electrically neutral. Since, they have equal number of positive and negative charges on them. So, they act as if they have no charge at all.

Hence, option A is correct.

Answer:

Explanation:

he SI rests on a foundation of seven (7) defining constants: the cesium hyperfine splitting frequency, the speed of light in vacuum, the Planck constant, the elementary charge (i.e. the charge on a proton), the Boltzmann constant, the Avogadro constant, and the luminous efficacy of a specified monochromatic source. Definitions of all seven (7) SI base units are expressed using an explicit-constant formulation and experimentally realized using a specific mises en pratique (practical technique).

The seven SI base units, which are comprised of:

Length - meter (m)

Time - second (s)

Amount of substance - mole (mole)

Electric current - ampere (A)

Temperature - kelvin (K)

Luminous intensity - candela (cd)

Mass - kilogram (kg)

The International System of Units (SI), commonly known as the metric system, is the international standard for measurement. The International Treaty of the Meter was signed in Paris on May 20, 1875 by seventeen countries, including the United States and is now celebrated around the globe as World Metrology Day. NIST provides official U.S. representation in the various international bodies established by the Meter Convention: CGPM - General Conference on Weights and Measures; CIPM - International Committee for Weights and Measures; and BIPM - The International Bureau of Weights and Measures.

The SI is made up of 7 base units that define the 22 derived units with special names and symbols. The SI plays an essential role in international commerce and is commonly used in scientific and technological research and development. Learn more about the SI in NIST SP 330 and SP 811.

Explanation:

The question is asking us to solve for the time of flight and the range of the rock.

Let's start by finding the total time it takes for the rock to land on the ground. We can use this constant acceleration kinematic equation to solve for the displacement in the y-direction:

We have these known variables:

And we are trying to solve for t (time). Therefore, we can plug these values into the equation and solve for t.

The time it takes for the rock to reach the ground is 4.08 seconds.

Now we can use this time in order to solve for the displacement in the x-direction. We will be using the same equation, but this time it will be in terms of the x-direction.

List out known variables:

We are trying to solve for:

By using the same equation, we can plug these known values into it and solve for Δx.

The rock lands 40.8 m from the base of the cliff.

Explanation:

A lysosome is a membrane-bound cell organelle that contains digestive enzymes. Lysosomes are involved with various cell processes. They break down excess or worn-out cell parts. They may be used to destroy invading viruses and bacteria.

The function of lysosomes is to remove waste as well as destroying a cell after it has died, called autolysis. A lysosome is an organelle containing digestive enzymes which it uses to function as the digestion and waste removal for cells, food particles, bacteria, etc.

Answer:

F = 159.07 N

Explanation:

Given that,

Mass of a tennis ball, m = 54.9 g = 0.0549 kg

It accelerates from rest to a speed of 45.1 m/s.

The impact with the racket gives the ball a constant acceleration over a distance of 35.1 cm = 0.351 m

We need to find the magnitude of net force acting on the ball.

Let a be the acceleration of the ball. Using third equation of motion to find it.

[tex]v^2-u^2=2ad\\\\a=\dfrac{v^2-u^2}{2d}\\\\a=\dfrac{(45.1)^2-(0)^2}{2\times 0.351}\\\\=2897.45\ m/s^2[/tex]

Net force,

F = ma

F = 0.0549 kg × 2897.45 m/s²

= 159.07 N

Hence, the net force acting on the ball is 159.07 N.

Answer:

P = 173.33 [W]

Explanation:

Power is defined as the amount of work done over a given time.

W = work = 520 [J]

t = time = 3 [s]

P = power [w]

Therefore by working relationship over time we can calculate the power.

[tex]P =W/t\\P = 520/3\\P=173.33[W][/tex]

Explanation:

344*8=

Starting from rest, the wheel accelerates to an angular velocity of

ω = (2.52 rad/s²) (7.03 s) ≈ 17.7 rad/s

then undergoes a new acceleration α until it comes to a rest. It does so in 11.9 revolutions, or with an angular displacement of (11.9 rev) • (2π rad/rev) = 23.8π rad. So α satisfies

0² - ω² = 2 α (23.8π rad)

α = - ω² / (47.6π rad)

α ≈ -2.10 rad/s²

Answer:

n =1.33 revolutions

Explanation:

Uniform Circular Motion

The angular speed can be calculated in two different ways:

[tex]\displaystyle \omega=\frac{v}{r}[/tex]

Where:

v = tangential speed

r = radius of the circle described by the rotating object

Also:

[tex]\omega=2\pi f[/tex]

Where:

f = frequency

Solving for f:

[tex]\displaystyle f=\frac{\omega}{2\pi}[/tex]

Since the frequency is calculated when the number of revolutions n and the time t are known:

[tex]\displaystyle f=\frac{n}{t}[/tex]

We can solve for n:

n=f.t

The particle moves in a circle of r=90 m with a speed v=25 m/s. Thus the angular speed is:

[tex]\displaystyle \omega=\frac{25}{90}[/tex]

[tex]\displaystyle \omega=0.278\ rad/s[/tex]

Now we calculate f:

[tex]\displaystyle f=\frac{0.278}{2\pi}[/tex]

[tex]f=0.04421\ Hz[/tex]

Calculating the number of revolutions:

n = 0.04421*30

n =1.33 revolutions

Answer:

1. 22092.31 m

2. 3188.78 m

3. 25.51 s

Explanation:

Let's split this projectile's motion into its horizontal and vertical components:

Since this projectile is in constant acceleration (9.8 m/s² vertically downwards and 0 m/s² horizontally), we can use the kinematic equations for constant acceleration.

Let's find the time it takes for the projectile to reach its greatest height first by using our knowledge that, at the top of its trajectory, the projectile will have a final velocity of 0 m/s before changing its direction and falling down.

Therefore, we can use the equation that contains the variables a_y, v_f, v_i, and t in order to solve for time t.

This equation is: v = v_0 + at, where v is the final velocity, v_0 is the vertical component of the initial velocity, a is the acceleration in the y-direction, and t is the time of flight of the projectile.

Plug known values into the equation:

Subtract 500 * sin(30) from both sides of the equation.

Divide both sides by -9.8.

The time it takes the projectile to reach its greatest height is 25.51 seconds.

Now we can use this time t to find the greatest height of the object, which will be the displacement in the y-direction at t = 25.51 seconds.

We can use this equation that contains the variables displacement (Δx), initial velocity (v_0), acceleration (a_y), and time (t):

Plug known values into the equation.

The displacement in the y-direction is 3188.78 m at half the time t, meaning that this is the greatest height of the projectile.

Now we can find the horizontal range of the projectile by using the same equation, but this time in the x-direction.

We will use the x-component of the initial velocity and the acceleration in the x-direction, which is always 0 m/s² assuming air resistance is negligible. Note that the time we have above (25.51 sec) is only half the total time, so we will use double this time (51.02 sec).

The horizontal range of the projectile is 22092.31 m.

Answer: It represents the whole distance traveled. Hope this helps!
