Answer:
Explanation:
As we know that there is no external torque on the system of platform, banana and the monkey
so the angular momentum of the system will remains conserved
so here we can say
here we know that
Now from above equation
Answer:
E
Explanation:
There is not enough information in the question. A beat is the observed differences between two frequencies.
Hence, 3 beat represents a difference of 3-hertz between the two frequencies. So the frequency of the piano string could be 1056+3 = 1059-hertz or 1056-3= 1053-hertz.
In order to ascertain the actual value i.e if it is an increase or a decrease in frequency observed, we need more information.
Answer:
When an object moves in a straight line, it is said to be in linear motion. By Newton's first law of motion, a body tends to be in rest or motion in a straight line until a net non-zero force acts on it.
Rate of change of position with respect to time is known as velocity. Uniformly accelerated motion refers to the motion where the rate of change of velocity with respect to time is constant.
Kinematic equations can be used to measure different aspects of a linear motion:
v = u + a t
s = u t + 0.5 a t²
v²= u² + 2 a s
where, u is initial velocity, v is final velocity, a is acceleration, t is time and s is displacement.
