Volume=mass/density
volume=455.6/19.3
volume=23.6 mL
True because friction happens when two things are rubbed against each other and it creates force and sliding something vigorously against something else can create force.
Explanation:
It is given that,
An electron is released from rest in a weak electric field of,
Vertical distance covered,
We need to find the speed of the electron. Let its speed is v. Using third equation of motion as :
.............(1)
Electric force is and force of gravity is . As both forces are acting in downward direction. So, total force is:
Acceleration of the electron,
Put the value of a in equation (1) as :
v = 0.010 m/s
So, the speed of the electron is 0.010 m/s. Hence, this is the required solution.
That would be only rotational motion
