C. Gravity acts on all objects in the universe.

Explanation:

Isaac Newton with his studies understood that the force of gravity acts on all objects with mass in the universe, and it is the same force that causes an apple to fall from a tree and that keeps the Earth in motion around the Sun.

Newtons also created a formula that allows us to calculate the force of gravity between two objects:

F=G\frac{m_1 m_2}{r^2}

where

G is the gravitational constant

m1 and m2 are the masses of the two objects

r is the separation between the two objects

V = 8 * 10^2 km/h = 800km/h
S= 1,8* 10^3 km = 1800km
t = ?
v = S/t
t = S/v
t = 1800km/ 800km/h
t ≈ 2,25h (135min)

The magnitude of the net force versus time graph has a rectangular shape. Often in physics geometric properties of graphs have p
Blizzard [7]

Answer:

True

Explanation:

In this particular case, the area of the graph represents the impulse.

In fact, impulse is defined as the change in momentum of an object:

I=\Delta p

Moreover, impulse is also defined as the product between the magnitude of the force acting on an object and the duration of the collision:

I=F\Delta t

If we plot a graph of the force versus the time, if the force is constant then this graph will have a rectangular shape, and the area under the graph will simply be the product

F\cdot \Delta t

which corresponds to the definition of impulse.

What is electricity <br>​
ser-zykov [4K]

Answer:

Electricity is the flow of electrical power or charge. It is a secondary energy source which means that we get it from the conversion of other sources of energy, like coal, natural gas, oil, nuclear power and other natural sources, which are called primary sources.

A 78-kg skydiver has a speed of 62 m/s , what is the kinetic energy?​
Cloud [144]

Answer:

149,916J

Explanation:

Pneumonic device: Kevin is half-mad and very square

this translates to: KE=(1/2)mv^2 !!

KE=(1/2)(78)(62^2)

KE=(39)(3844)

KE=149,916 Joules
