Work=force X distance
Newtons is a measurement of force
4 meters is your distance 60×4=240
240 joules
Gravity increases as mass increases.
Gravity decreases when distance decreases
I hope I help.
A :-) F = mv^2 by t
Given - m = 10 kg
r = 10 m
v = 10 m/s
Solution -
F = mv^2 by t
F = 10 x 10^2 by 10
F = 10 x 100 by 10
( cut 10 and 10 because 10 x 1 = 10 )
F = 100 N
.:. The centripetal force is 100 N
Answer:
0.237 (23.7 %)
Explanation:
The thermal efficiency of an engine is given by:

where
W is the useful work output of the engine
is the heat in input
Here we have:

and the work done is the total heat in input minus the heat exhausted:

So, the efficiency is
(23.7 %)
