Explanation:
this is my answer this is helpful for you
Answer:
Part a)
When there is no friction then acceleration is

Part b)
if there is friction force along the inclined then acceleration is

Explanation:
Part a)
As we know that the skier is on inclined plane
So here if there is no friction then net force along the inclined plane is given as

now acceleration of the skier is given as




Part b)
if there is friction force along the inclined then net force along the inclined plane is given as

now acceleration of the skier is given as




The distance that the canoe moves in this process is 1.29 meters.
We first have to find the center of mass

Where
Ms = Woman's mass = 45
Mc = Canoe's mass = 60kg
Xs = position from left= 1 cm
Xc = position from left end of canoe's mass = 2.5cm
When we put these values into the equation we have:

The center of gravity lies at the center of this boat. Therefore,

5.00 - 1. 00 = 4 meters

To get the distance that is moved by this canoe
distance = 3.143-1.857
= 1.286
≈ 1.29 meters
The distance that the canoe moves in this process is 1.29 meters.

No, if it takes less time, the acceleration is greater.

Direct current is the unidirectional flow of an electric charge.
The term 'unidirectional' in the statement means that direct current only moves in one direction. Direct current usually produced by things such as batteries, dynamos, and power supplies
