Swaralee takes 20 S to carry a bag weighing 20 kg to a height of 5 CM. How much power has she used?
Answers
Answer: Power used by Swaralee is 24.5 W.
Explanation:
Given:
m = 20 kg
h = 5 m
t = 40 s
To find: We have to find power used by Swaralee to carry bag.
Force applied by Swaralee,
F = mg = 20 * 9.8
F = 196 N
Work done by Swaralee to carry the bag to a height of 5 m,
W = F s = 196 * 5 = 980 J
By using the formula of Power,
Power = work / time
Power = 980/20
Power = 24.5 W
Therefore, Power used by Swaralee is 24.5 W.

velocity is the directional speed of a item in movement as a demonstration of its charge of alternate in role as discovered from a particular frame of reference and as measured by way of a particular wellknown of time (e.g. 60 km/h northbound).[1] speed is a essential concept in kinematics, the branch of classical mechanics that describes the movement of bodies.
speed is a physical vector quantity; both significance and course are had to define it. The scalar absolute value (significance) of speed is known as velocity, being a coherent derived unit whose quantity is measured in the SI (metric gadget) as metres according to 2d (m/s or m⋅s−1). for instance, "five metres according to 2nd" is a scalar, whereas "five metres according to second east" is a vector. If there may be a exchange in velocity, path or each, then the object is stated to be present process an acceleration.
