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.

the temperature and the pressure affect solubility. temperature affects by changing the properties of the solvent. the increase in pressure increases solubility, the decrease in pressure decreases solubility.
