Can be absorbed and transformed into heat. i know this because i used to work as a constructor for lights and i had to go over a training on this subject.
Answer:
F = 3.01 N
Explanation:
Given that,
Mass of a block, m = 2.75 kg
Force applied to the block, F = 5.11 N
It is directed 53.8° above horizontal.
We need to find the total force acting on the block. The force acting on it is given by :

So, 3.01 N of force is acting on the block.
Answer:
The induced current will flow in a direction north of the plane of the paper
Explanation:
This is in compliance with faraday's right hand rule pictured below.
Explanation:
The given data is as follows.
width = 100 m, speed = 3 m/s
So, minimum time required to cross the stream is calculated as follows.
t =
Also, in the same time the man has moved downstream by 50 meter.
Hence, distance traveled downstream is as follows.
d = velocity of river × t

= 
= 
= 1.5 m/s
Thus, we can conclude that the river is flowing by 1.5 m/s.
