Which response accurately describes a balanced force?
question 7 options:
a. a 25-n force acts on the left side of the marble at the same time as a 25-n force acts on the right side of the marble.
b. a marble resting on the sidewalk suddenly begins to roll downhill without being touched.
c. a 2-n force presses down on the marble at the same time as a 1.5 n-force presses up on the marble.
d. a marble rolling downhill suddenly comes to rest at a garden wall.

a. A 25-N force acts of the left side of the marble at the same time as a 25-N force acts on the right side of the marble.

Explanation:

When trying to balance an object, you must keep the same amount of weight on each side to keep it in the middle. Think of a seesaw: whatever side has more weight pressure is the side that falls first. Hence, the correct answer is A.

radiation

explanation:

heat is transmitted by radiation

answer: the metamorphic rocks are formed when they are exposed to high pressure and high temperatures. this happens when one of the earth's plates comes in contact with the other plate by traveling in opposite directions, straight into each other or slipping under one another. the friction that is caused by this activity results in   melting of rocks and when it cools they are known as metamorphic rocks. this process needs a controlled amount of pressure and temperature otherwise it may turn into magma.
