It is trajectory acceleration. A friction track is a device to study motion in low friction environments, I believe. Does this help?
To solve this problem we will apply the concepts related to the Force of gravity from Newtonian theory for which it is necessary to
Where,
G = Gravitational universal constant
M = Mass of Earth
m = mass of Object
x = Distance between center of mass of the objects.
From this equation we can observe that the Force is inversely proportional to the squared distance between the two objects. The greater the distance, the lower the force of gravity and vice versa.
If you want to increase the force of gravity, you need to reduce the distance of the two. Therefore the correct option is B. Talk to the distance between them.
Nuclear power generates alot of power, ALOT. It requires Uranium and other radioactive substances to power it, which over time can degrade and become depleted. This radioactive waste would have to be placed somewhere, and it accumulates over time slowly.
Answer:
D.The striking foot pushes backward against the ground. The friction with the ground provides an equal and opposite force forward
Answer:
Explanation:
The distance will be the total distannce covered during the journey.
If you move 3 meters East and move 4 meters north, then the distance will be calculated as;
Distance = distnace through East+distance through north
Distance = 3m + 4m
<em>Distance = 7m</em>
Displacement is the distance covered in a specified direction. It is the shortest distance covered by me. This can be gotten using the Pythagoras theorem.
d² = 3²+4²
d² = 9+16
d² = 25
d = √25
d = 5m
<em>Hence the displacement of the object is 5metres</em>
