Then the object moves in a circle.
Answer:
Quantum.
Explanation:
Quantum is defined as the discrete quantity of energy proportional in magnitude to the frequency of the radiation it represents.
It is the minimum amount of any physical entity (physical property) involved in an interaction or to put simply, it is defined as the minimum amount of energy that can be absorbed or released by matter.
Answer: either 3.20s or 1.18s
Explanation:
r = radius of the circle traveled by the particle = 76 cm = 0.76 m
T = time period of revolution for the particle = 4.5 s
w = angular velocity of the particle
angular velocity of the particle is given as
w = 2π/T
inserting the values
w = 2 (3.14)/4.5
w = 1.4 rad/s
a = centripetal acceleration of the particle in the circle
centripetal acceleration is given as
a = r w²
inserting the values
a = (0.76) (1.4)²
a = 1.5 m/s²
