Answer:
8-5=3
The bigger force is to the left
3N to the left
Explanation:
A measure of the quantity of matter is called mass. D.
This is how much of matter is contained in an object. It is different from weight, which is the pull of gravity on an object.
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.
