No, light does not have mass because a photon does not way anything.
Answer:
25 N; 250 W.
Explanation: Work Done
=
Force
×
Displacement
×
cos
(
The angle between Force and Displacement
)
So, Let's Assume the Force to be
x
Newtons.
So, According to The Sum,
×
x
x
⋅
100
=
2500
⇒
x
=
25
00
1
00
=
25
So, The force was
25
N
.
And, We also know,
Power
=
Work Done
Time
So,
The Power of the Machine =
2500
10
Watts
=
250
Watts
Nope Copper is a better conductor
