ANS: The correct answer to the question is coefficient of friction.
EXPLANATION:
Let us consider a body resting on a table. The weight of the body is acting in vertical downward direction. The table also exerts an equal amount of force perpendicular to the surface of the body which is called normal reaction.
Here, normal reaction [N] = Weight [W]
Let an external force is applied on the body which will cause motion on the body. As the body is resting on the floor, friction will come into existence which will oppose the relative motion between table and body.
Let F is the force of friction.
The force of friction is directly proportional to the normal reaction. Mathematically we may write F ∝ N
Here, is a proportionality constant called the coefficient of friction.
⇒ [∵N= W]
From above, it is obvious that coefficient of friction is a unitless quantity.
Hence, the amount of friction divided by the weight of an object forms a unitless number called the coefficient of friction.
The same force accelerates a small mass faster than
it accelerates a large mass.
It's easier to get a little red wagon going by pushing it
than it is to get a school bus going by pushing it.
Answer:
2.4681 m/s
Explanation:
= Mass of cannon ball = 29 kg
= Mass of performer = 65 kg
= Initial Velocity of cannon ball = 8 m/s
= Initial Velocity of performer = 0 m/s
v = Velocity of combined mass
As the linear momentum of the system conserved
The recoil velocity is 2.4681 m/s
Answer:
ACCELARATION
The slope of a velocity graph represents the acceleration of the object. So, the value of the slope at a particular time represents the acceleration of the object at that instant.

In a parallel circuit nothing happens. All the other lights stay on but if it was a series circuit ALL the lights would turn off at one time.
If there is an ABCD question I can answer that but I wasn't sure so I just said this
Hope it is helpful :)
