Answer:
0.5 m/s²
Explanation:
Applying,
F = ma............... Equation 1
Where F = Force applied to the chair, m = mass of the student, a = acceleration of the chair
make a the subject of the equation
a = F/m............ Equation 2
From the question,
Given: F = 35 N, m = 70 kg
Substitute these values into equation 2
a = 35/70
a = 0.5 m/s²
Hence the new acceleration of the chair is 0.5 m/s²
Given :
Number of operations move through a pocket calculator during a full day's operation , 
.
To Find :
How many coulombs of charge moved through it .
Solution :
We know , charge in one electron is :
So , charge on n electron is :
Therefore , -21.44 coulombs of charge is moved through it .
Hence , this is the required solution .
The vertical component is given by the sin of the angle. So this is 20*sin(53)=15.97m/s
