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.)

Instructions: Create a comic strip detailing the adventure of your character as the character is exposed to thermal energy, causing it to undergo phase changes from a solid, to a liquid, to a gas. Place drawings inside the boxes and written content on the lines below each box.
Your presentation must include the following:
• title and introduction of your character, including what substance it is made of
• source of thermal energy your character encountered (conduction, convection, and/or radiation)
• detailed description and/or diagram of the particle transformation from solid to liquid phase
• detailed description and/or diagram of the particle transformation from liquid to gas phase

I am stuck on this assignment for 2 weeks, Please Help me

The sun is brighter than all other stars because of its:

absolute magnitude
luminosity
apparent magnitude

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

pls help asappppppppppp

The distance of Saturn from the sun is:

< 1 A.U.
> 1 A.U.
= 1 A.U.

The diagram below shows the sun and four positions, A, B, C, and D, of the moon around Earth. (1 point)

Two circles are shown. The smaller circle is on the left and is labeled Earth. It has the label B on top, C on the right, D at the bottom, and A on the left. The larger circle is labeled Sun and is on the right of the circle labeled Earth

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.
