The gravitational forces between two masses are inversely proportional
to the square of the distance between them ... the closer together the two
masses are, the stronger the gravitational forces between them are.

If two artificial satellites with equal masses are orbiting earth, and one
satellite is orbiting closer to earth than the other satellite, then <span>the forces
between the Earth and the closer satellite are stronger than the forces
between the Earth and the satellite that's farther out.

a 1.2 kg rocket is launched from ground level with initial velocity of 12 m/s. What is the maximum height the rocket can reach?
Tanzania [10]

As the rocket is launched from the ground its height will go on increasing till it stops

So the height of rocket will be maximum when its speed becomes zero

so here we can use energy conservation theory

PE = KE

mgH = \frac{1}{2}mv^2

9.8*H = \frac{1}{2}*12^2

H = 7.35 m

So it will reach upto height 7.35 m

What is negitive acceleration?<br>​
Wewaii [24]

According to our principle, when an object is slowing down, the acceleration is in the opposite direction as the velocity. Thus, this object has a negative acceleration.An object with negative acceleration could be speeding up, and an object with positive acceleration could be slowing down.

answer

1)the direction is from the body of a high temperature to a body at a low temperature

2)at the melting point and boiling point because the heat given is used to break down the forces holding the particles together so that they can change their state

3)In a gas because the particles of gases are held by weak forces thus have large intermolecular spaces between the particles while the solids are in a fixed position

4)heat is transferred to another body if they experience different temperatures

8. An airplane of mass 8500 kg dives has an altitude of 15,000 m. It then dives steeply to an
Ivan

Answer:

333.5 MJ

Explanation:

ΔV = m·g·Δh

     = 8500 · 9.81 · (15000-11000)

     = 8500 · 9.81 · 4000

     = 333 540 000

     ≈ 333.5 ·10⁶J = 333.5 MJ
