Answer:
The law of conservation of energy is the preserved form of energy.
Option (1) is correct that is the total amount of energy in the universe remains constant.Because energy is conserved.
Option (3) is correct since, it is conserved so, it can not be created or destroyed.
Option (4) Energy can change from one type to another like mechanical to electrical energy but it will remain conserved.
Option (5) is correct because in closed, isolated system energy is conserved.
If a system allows the exchange of energy but does not permit exchange of matter between the system and surroundings, this system is classified as a CLOSED system. The energy that flows in and out of the system boundaries is in the form of heat.
Provided the dots represent time-lapse snapshots of an object's motion from left to right, then
(a) The underlying object is slowing down because the distance between adjacent snapshots (dots) decreases with time

Tangential acceleration of a point on the rim of the flywheel during this spin-up process is 0.2548 m/s².
Tangential acceleration is defined as the rate of change of tangential velocity of the matter in the circular path.
Given,
Radius of flywheel (r) = 1.96 cm = 0.0196m
Angular acceleration (α)= 13.0 rad/s²
The tangential acceleration formula is at=rα
where, α is the angular acceleration, and r is the radius of the circle.
using the formula; at=rα = (13.0 rad/s²) (0.0196m) = 0.2548 m/s².
The tangential acceleration is 0.2548 m/s².
