Answer:
W = 750 Joules.
Explanation:
Given that,
Force acting on the object, F = 50 N
Distance moved by the object, d = 15 m
To find,
Work done by the object
Solution,
Let W is the work done by the object. It is given by the product of force and distance. Its expression is given by :
Here, 
(force and distance are in same direction)
W = 750 Joules
So, the work done by the force is 750 Joules.
Answer:
so you know the units in the problem and answer are the same, if they aren't you have to convert them to the same units.
Answer:
The differences are:
Mass:
1) It is the total amount of matter contained in a body.
2) It's SI unit is kilogram (kg).
3) It's measured by using beam balance
Weight:
1) It is the force which pulls an object towards the center of the earth.
2) It's SI unit is newton(n).
3) It's measured by using spring balance.
plz mark brainliest ✌️✌️
Plant and animal life, atmosphere and water are the major causes of weathering .
Yhuihoifjhh <span>F = Gm1m2 / r^2
if the masses are doubled then the force is increased by a factor of 4
if the distance is doubled the force is decreased by a factor of 1/ 2^2
the net result is no change in force</span>
