If you are referring to stars, the answer would then be pressure from the nuclear reactions
The thermal pressure that pushes outward and against the pull of gravity in a star is caused by the nuclear reactions that is happening within the stars core. A lot of energy is released during these reactions which produce thermal pressure. The pressure then pushes outward.
<span>Correct pairs:
a man jogging in the park --> motion energy (the energy is the kinetic energy of the man, moving with speed v)
a fully charged camera battery --> electric potential energy (the battery is fully charged, so it can deliver electrical energy when the camera is turned on)
a stove burner that’s turned on --> radiant energy (the stove burner emits energy by radiation)
an apple on a tree --> gravitational potential energy (when the apple is on the tree, it has gravitational potential energy equal to U=mgh, where m is the apple's mass and h its height from the ground)

Explanation:
Earth’s orbit around the Sun represented as :
1 AU = 4 inches
Therefore,
<u>Inner edge</u> of the Oort Cloud represented as :
10,000 AU = 40,000 / 63360 = 0.631 miles
<u>Outer edge</u> of the Oort Cloud represented as<u>:</u>
100,000 AU = 400,000 / 63360 = 6.31 miles
Answer:
a) 0.040625 m
b) 5.02272 J
Explanation:
k = Spring constant
x = Stretched length
F = Force
a)
Extension of the spring would be 0.040625 m
b) Work done in a spring
The work done by the shopper to stretch this spring a total distance of 8.00 cm is 5.02272 J
Weight = (mass) x (gravity)
On Earth ...
Weight = (1 kg) x (9.8 m/s^2)
Weight = 9.8 Newtons
