Answer:
Pushing molecules like a wave.
Explanation:
Well it seems that you did not give answer choices, but that its fine since we can use newtons law of universal gravitational, Fg = GM1M2/r^2. So G is the gravitational constant, which is 6.67*10^-11, we can plug in 6*1024 for M1, and 7*1022 for M2, and 3.8*108 for r. Which then we get 1.74 * 10^8 N as the force of attraction between the Earth and the moon.

When the angle of the ramp increases, the weight of the box acting perpendicular to the ramp decreases.
<h3>
Normal reaction of the box</h3>
The normal reaction of the box is due to weight of the box acting perpendicular to the ramp.
Fn = Wcosθ
<h3>when the angle of the ramp = 30⁰</h3>
Fn = Wcos(30)
Fn = 0.866W
<h3>when the angle of the ramp = 45⁰</h3>
Fn = W x cos(45)
Fn = 0.7071W
Thus, when the angle of the ramp increases, the weight of the box acting perpendicular to the ramp decreases.

Popcorn can be popped by either of the three forms of heat transfer:
Conduction in a pan with hot oil on a stove element.
Convection by an air popper and warm air rising over a heating element... no direct contact with heat source.
Radiation is what occurs in a microwave. Invisible radiant heat activates water molecules in the popcorn.
All the above heat the kernel over 100 Celsius. Water vaporizes/boils (latent heat) and erupts through the kernel.
Mmmm popcorn watch out for the lipids (fat in the oil and butter)
