Answer:
The correct answer is spin faster.
Explanation:
The angular momentum or kinetic moment is a physical magnitude, rotational equivalent of the linear momentum and represents the amount of rotational movement of an object. It is a vector quantity that characterizes the inertia properties of a body, which rotates in relation to a certain point. It is found in the three mechanics (classical, quantum and relativistic mechanics). In the International System of Units the angular momentum is measured in kg · m² / s. This magnitude plays a role similar to the linear moment in the translations with respect to the rotations.
Explanation:
a. the total time taken for the journey is 50sec.
b. u=0, v=10m/sec, t=20sec.
a=(v-u)/t = (10-0)/20 = 10/20 = 0.5 m/s².
hope this helps you to solve the problem.
Answer:
4 is initial distance and 6 is final distance or displacement
Explanation:
displacement is the shortest distance between final and initial distance...
Answer:
False
Explanation:
The object could be in a constant velocity and the sum of both the external torques and the external forces on an object is zero. Newton's first law states that when the total net force is 0 or there is zero force, the object could be at rest OR remain in constant velocity. It's not necessary at rest.
Answer:
B = A : 2
Explanation:
because is the opposite of A=2B
