Answer: 20 m/s
Explanation:
P = mv
since we're trying to find the velocity, you change the formula to v = P/m
v = ?
P = 9 kgm/s
m = 0.45 kg
v = 9 kgm/s / 0.45kg = 20 m/s
Yes but then you need to find out what will happen then try the other wire
The coefficient of friction has no units.
Answer: Option D
<u>Explanation:
</u>
The coefficient of friction, just a measure of the relationship between normal forces when two bodies are in contact. It is a ratio-like quantity, where the numerator and the denominator are of same units. The coefficient of friction is a scalar.
This is used to determine the frictional forces acting on the body, in physics. It is simply, the tangent of the angle of friction, and hence, has no units. Coefficient of friction reduces the object's speed, or supports to change the state of an object. It acts, only when the surface which is in contact with the body, is rough.
Answer:
D.
For every action there is an equal and opposite reaction.

im doing the same one lol
