Answer: Friction

Explanation:

The friction force is the force exerted by a surface as an object moves across it or makes an effort to move across it. There are at least two types of friction force - sliding and static friction. Though it is not always the case, the friction force often opposes the motion of an object.

Logically why would light move faster in vacuum than in a solid? *

light cannot travel in vacuum; it needs a medium to travel in just like mechanical waves
this is incorrect, light moves faster in a solid
in a solid light gets absorbed by atoms before coming out the other side
there's nothing for light to bounce off of in vacuum

The coating on the head of a match is highly flammable. When it burns, it releases a great deal of energy. However, before the match can burn, it must gain a small amount of energy from a spark. That spark is typically produced by striking (rubbing) the match head against a rough surface.
Sketch and describe a potential energy diagram that represents the striking and burning of the match. Remember to label the diagram with the energy changes that occur. Your answer must include the potential energy diagram and a written description.
(Note: you do not have to use actual energy values.)

Which of the following statements is correct about the type of tide that would be created based on the placement of the moon according to the image above?

1.If the moon is at A, a neap tide will occur because the gravitational pull of the moon cancels out some of the pull from the sun to create lower than normal tides.

2.If the moon is at B, a neap tide will occur because the moon's gravitational force increases due to the shadow of the sun.

3.If the moon is at C, a spring tide will occur because the combined gravitational pull of the moon and sun creates higher than normal tides.

4.If the moon is at D, a spring tide will occur because the sun's gravitational force is reduced due to the shadow of the moon.
