The answer of a & b are force of cohesion and force of adhesion
Of rest two answers I don't know
4, because 3+1=4 and displacement is the amount of distance traveled. Hope this helps!
In physics, we define speed as:
speed = distance / time, or
In order for this to work properly - we need to convert 1.9 minutes into seconds. One minute is 60 seconds, nine tenths of a minute is 54 seconds. So 1.9 minutes in seconds is 60 + 54 = 114.
Now just solve the fraction.
Jude travels .06 m/s.
Answer:
F= 12 N
Explanation:
Given that
Work done by student ,W= 60 J
The mass of the box ,m = 3 kg
Length ,x = 5 m
We know that ,The work done by a force a force F is given as
W= F .x
x=Displacement
F=Force
W=Work
Now by putting the values
60 = F x 5
F= 12 N
That is why the magnitude of the force will be 12 N.
