Answer:
Here the answer is attached
Explanation:
Answer;
The above statement is True
Kinetic friction is affected by the weight of the object.
<h3><u>Explanation;</u></h3>
- Kinetic friction is a force that acts between moving surfaces. An object that is in motion over a surface experiences a force in the opposite direction to the direction of movement.
- The equation for kinetic friction is given by the formula;
F= coefficient of friction * Normal force.
- Normal force is the force of the table pushing back on the block and can be calculated by formula;
F = mass* acceleration due to gravity.
- Therefore, the weight of an object determines its kinetic friction.
Answer:
divide the mass value by 1e+8
Answer: (1) 5.0 x 10^ -10 s
Explanation:
1.5 x 10^-1 m / 3 x 10^8 = .5 x 10^-9
= 5 x 10^-10
