things that happen because of limited food sources and land area

differences among similar species

things that happen because of limited food sources and land area

differences among similar species

Which of Newton's laws of motion explains why you must lift a cup if you want to drink from it?

1st law--An object at rest will stay at rest and an object in motion will remain in motion unless a force acts upon it.

2nd law--The amount of force needed to move an object depends on its mass and acceleration.

3rd law--For every action there is an equal and opposite reaction

4th law--Gravity depends on mass and distance

Minerals have several properties including color. What does its color depend on?

its composition (the chemical it's made of)

Why does the Earth orbit the Sun and not a planet in the solar system?

The Sun is more massive than the planets so it's mass causes the gravitational pull.

The Earth is closer than the other planets so the distance causes the gravitational pull.

Some objects like the Sun produce their own light. Others don't. Why can we see objects that don't produce light?

They bounce the light around until it strikes our eyes.

Suppose you jump off a the front of a skateboard. What are the action and reaction forces between you and the skateboard?

You provide the action force and the boat reacts by moving backwards.

The skateboard provides the action force and you react by jumping forward.

There are two action forces and no reaction forces in this example.

The forces are equal and opposite. There's no action and reaction force.

What's a mid-ocean ridge?

An underwater mountain range formed where two plates separate.

An underwater mountain range formed where two plates collide.

Suppose you have a block of wood that has a mass of 5 kg. What will happen to the speed of the wood if you apply 10, 20, & 40 N of force to the block for 10 seconds.

The final speed will be four times the speed produced by the 10 kg force.

The final speed will be 80 times the speed produced by the 10 kg force.

What kind of adaptation would you be most likely to see in these little moles that live underground?
