Answer:B
Explanation:
As you are sitting on the chair, gravity tends to pull you downwards but the normal reaction exerted by the chair is just enough to keep you from falling downwards. It works in the upward direction
Answer:
A.
Explanation:
The speed or celerity of deep-water waves increases with increasing water depth.
With increase in depth, the pressure inside the increases as p=ρgh.
And with this increase in pressure force associated with waves increase because force is directly proportional to the pressure. Now greater the force greater will be accleration and greater velocity is obtained.
Answer:
Distance covered 28 km
displacement is 22.8 km North-East
Explanation:
Distance shows how far apart objects or points are from each other. The distance he covered is the sum of all the distance travelled. Therefore:
Distance covered = 12 km + 6 km + 10 km = 28 km
Displacement is a vector quantity (has direction). It is the overall change in position.
The total distance traveled north = 12 km + 10 km = 22 km
The distance traveled east = 6 km
The displacement (d) is:
d² = 22² + 6² = 484 + 36
d² = 520
d = √520 = 22.8 km
Therefore the displacement is 22.8 km North-East
