The planet Venus has a mass of 4.87 × 10^24 kg, and Earth has a mass of 5.97 × 10^24 kg. How far apart are the two planets when they exert a gravitational force of 1.12 × 10^18 N on one another?
Taking into account the Universal Law of Gravitation, Venus and Earth are separated by a distance of 1,316,302,384 m.
Universal Law of GravitationThe Universal Law of Gravitation establishes that bodies, by the simple fact of having mass, experience a force of attraction towards other bodies with mass, called gravitational force.
The Universal Law of Gravitation states that the gravitational force between two bodies is directly proportional to the product of their masses and inversely proportional to the square of the distance that separates them. Mathematically it is expressed as follows:
[tex]F=G\frac{Mm}{d^{2} }[/tex]
where:
G is the universal gravitational constant, with a value of 6.67×10⁻¹¹ [tex]\frac{Nm^{2} }{kg^{2} }[/tex].M and m are the masses of the bodies that interact.d is the distance that separates them.Distance of Venos and EarthIn this case, you know:
F= 1.12×10¹⁸ NG= 6.67×10⁻¹¹ [tex]\frac{Nm^{2} }{kg^{2} }[/tex]M= mass of Venus= 4.87×10²⁴ kgm= mass of Earth= 5.97×10²⁴ kg d= ?Replacing in the Universal Law of Gravitation:
[tex]1.12x10^{18} N=6.67x10^{-11} \frac{Nm^{2} }{kg^{2} }\frac{4.87x10^{24} kgx5.97x10^{24} kg}{d^{2} }[/tex]
Solving:
[tex]1.12x10^{18} N=6.67x10^{-11} \frac{Nm^{2} }{kg^{2} }\frac{2.90739x10^{49} kg^{2} }{d^{2} }[/tex]
1.12×10¹⁸ N÷ 6.67×10⁻¹¹ [tex]\frac{Nm^{2} }{kg^{2} }[/tex]= [tex]\frac{2.90739x10^{49} kg^{2} }{d^{2} }[/tex]
1.678×10 ²⁸[tex]\frac{kg^{2} }{m^{2} }[/tex]= [tex]\frac{2.90739x10^{49} kg^{2} }{d^{2} }[/tex]
1.678×10 ²⁸[tex]\frac{kg^{2} }{m^{2} }[/tex]× d²= 2.90739× 10⁴⁹ kg²
d²= 2.90739× 10⁴⁹ kg²÷ 1.678×10 ²⁸[tex]\frac{kg^{2} }{m^{2} }[/tex]
d²= 1.73265 m²
d= √1.73265 m²
d=1,316,302,384 m
Finally, Venus and Earth are separated by a distance of 1,316,302,384 m.

Jeff is out in the woods, trying to heat 0.5 kg of water to make sure it is safe to drink. He knows from his survival handbook that he needs to add
157.125 kJ of heat to the water in order to make it safe. What is the change in temperature that the water will experience after that heat is added?
(Note: Water has a specific heat of 4,190 J/kg°C.)

The temperature change is 75 degrees.
What is specific heat capacity?The specific heat capacity of a substance is the amount of heat added to a substance in order to make the temperature of 1 Kg of the substance to rise by 1 degree.
We know that;
H = mcdT
Where;
H = heat added
m = mass of water
c = heat capacity of water
dT = temperature change
So;
157.125 × 10^3 = 0.5 × 4,190 × dT
dT = 157.125 × 10^3/0.5 × 4,190

A car weighs 6000 N on the Earth's surface, what is its weight 3 times
Earth's radius away from the center of the Earth? (N)
Answer:
667 N
Explanation:
[tex]\pink{\frak{Given}}\Bigg\{ \textsf{ A car weighs 6000 N on the Earth's surface.}[/tex]
And we need to find out the weight of the car at a distance equal to 3 times the radius of the earth , from the centre of the earth.
We can find the acceleration due to gravity at a height h from the earth's surface as ,
[tex]\sf\longrightarrow \red{ g_h = g\bigg[ 1 +\dfrac{h}{R_e}\bigg]^{-2}}[/tex]
The height here will be 3R - R = 2R , since 3R is the distance from the centre of the earth .In above equation multiply both sides by m ,
[tex]\sf\longrightarrow mg_h = mg\bigg[ 1 +\dfrac{h}{R_e}\bigg]^{-2}[/tex]
Now here at the place of mg we can substitute 6000N , and mg[tex]_h[/tex] will be the weight at height h which we are interested in finding .
[tex]\sf\longrightarrow W_h = 6000 \bigg[ 1 +\dfrac{2R}{R}\bigg]^{-2}\\[/tex]
[tex]\sf\longrightarrow W_h = 6000 [ 1 + 2 ]^{-2}\\ [/tex]
[tex]\sf\longrightarrow W_h = 6000 [ 3]^{-2}\\[/tex]
[tex]\sf\longrightarrow W_h = 6000 \times \dfrac{1}{3^2}=\dfrac{6000}{9}\\ [/tex]
[tex]\sf\longrightarrow \boxed{\bf Weight_h = 667N \ \ (approx) } [/tex]

A car is approaching a stoplight. When the car is 200 m from the stoplight, the light turns yellow. The driver now has three seconds to either come to a stop, or hurry through the intersection before the light turns red. The car's initial velocity is 50 m/s, and it can accelerate at a maximum of 8 m/s^2. Determine if the car can make it through the light.
Apply third equation of kinematics
[tex]\\ \tt\hookrightarrow v^2-u^2=2as[/tex]
[tex]\\ \tt\hookrightarrow (50)^2=2(200)(8)[/tex]
[tex]\\ \tt\hookrightarrow 2500=16(200)[/tex]
[tex]\\ \tt\hookrightarrow 200=2500/16[/tex]
[tex]\\ \tt\hookrightarrow 200>156.25[/tex]
Unfortunately the car cannot make it through

What can moving electric charge produce? In what direction is it generated?
Answer:
Explanation:
answer: it can produce a magnetic field and it it generated counter clock wise -8th grade
Charges are made by electrons or protons or other particles with active energy to conduct. Moving charges produce an electric current and an associated magnetic field.
What is electric field?An electric field is created by the electric charges and the resulting force of field lines. There are both positive and negative charges. Electrons are negatively charged particles whereas positively charged particles are called protons.
The movement of charges creates the electric current or electricity. The direction of electric current is opposite to the passage of electrons. In all electronic devices and electrolytes, the electrons and positive ions have a mobility and they generate current.
A moving electric field is associated with a magnetic field in a perpendicular direction. For example earth is a rotating magnet. Because, the charges in the earth produce the electric current which when rotates results in a magnetic field in the perpendicular direction.

Aluminum allows for the flow of electrons, while glass does not. Would an aluminum wire surrounded by glass be an effective design for a device that will need to carry an electric current?(1 point)
No, it would not. Both aluminum and glass are insulators, so the device would not carry a current.
Yes, it would. The glass would carry the current, while aluminum is an insulator.
Yes, it would. Aluminum is a conductor, and the glass would prevent electricity from transferring to a person holding the device
No, it would not. Both aluminum and glass are conductors, so the current would be exposed to outside elements.
answer
no
Explanation:
I do not think that I would because even though its a conductor in the insulator I think it would insulate it before it will work (not sure if that makes sense)
Aluminum is a conductor, and the glass would prevent electricity from transferring to a person holding the device.
What is meant by a conductor ?A substance or material that permits electricity to flow through it is known as a conductor or electrical conductor.
Here,
When potential difference is provided, electrical charge carriers, often electrons or ions, travel effortlessly from atom to atom in a conductor.
Since aluminium foil is a recognized conductor of electricity, when a charge is given to it, electrons can pass freely through the material.
By allowing electrons to easily move through its structure, aluminium acts as a conductor of electricity. This is feasible because the atoms that make up the structure of aluminium have three valence electrons in their outermost shell, which makes them highly reactive and ideal for carrying electrical currents.
Glass is an insulator.
A material that blocks the movement of electrons is known as an insulator, and as a result, it prevents the flow of electric current.
Hence,
Aluminum is a conductor, and the glass would prevent electricity from transferring to a person holding the device.

When capacitors are wired in series what must be the same for the two capacitors?.
Answer:The charge on them
Explanation:
When capacitors are wired in series, the charge on each capacitor must be the same.
What are capacitors?Two conductors that are separated from one another and positioned close to one another make up a capacitor, an electrical energy storage device. A parallel-plate capacitor is a simple example of one such storage device.
As each capacitor in the series receives the same amount of current, they all build up the same amount of charge.
Yet, based on the capacitance of each capacitor, the voltage across each capacitor in a series circuit will vary. The following equation may be used to get the voltage between each capacitor:
V = Q/C
Where V is the voltage across the capacitor, Q is the charge on the capacitor, and C is the capacitance of the capacitor.
In a series circuit, the total capacitance is given by the formula:
1/C_total = 1/C₁ + 1/C₂ + 1/C₃ + ...
Where C₁, C₂, C₃, etc. are the series circuit's capacitors' separate capacitances.
So, even if the voltage across each capacitor may vary, the charge on each capacitor in a series circuit must be the same.
