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:
Probably the more correct version of the story is that Newton, upon observing an apple fall from a tree, began to think along the following lines: The apple is accelerated, since its velocity changes from zero as it is hanging on the tree and moves toward the ground. Thus, by Newton's 2nd Law there must be a force that acts on the apple to cause this acceleration. Let's call this force "gravity", and the associated acceleration the "acceleration due to gravity". Then imagine the apple tree is twice as high. Again, we expect the apple to be accelerated toward the ground, so this suggests that this force that we call gravity reaches to the top of the tallest apple tree.
Changing the tilt of the axis from 23 degrees to 45 degrees would dramatically change the seasons. They would be more extreme. Increasing the tilt angle means a larger section of the earth would experience one season for a longer period. There would be longer and colder winters and likewise hotter and longer summers.
Answer: In a logical Pace forum subject to the distance
Explanation:
Answer:
40 J
Explanation:
= 4 C
= 2 C
= 20 J
The potential energy is directly proportional to the charge of the particle
The potential energy expected is 40 J
