<span>Net charge of the object = 0.500 ÎĽc
The charge of electron = -1.602 x 10^-19 C
Calculating the net change in the number of electrons = 0.5 x 10^-6 / -1.602 x 10^-19 = - 3.12 x 10^12
The negative sign implies the number of electrons that needs to be removed that is 3.12 x 10^12</span>
Answer:
4
Explanation:
you have to divide the velocity by time so 40 divided by 10 and the answer should be 4
Answer:
Length of the pendulum will be 3.987 m
Explanation:
We have given time period of the pendulum T = 8 sec
Acceleration due to gravity 
We have to find the length of the simple pendulum
We know that time period of the simple pendulum is given by



So length of the pendulum will be 3.987 m
The substance that a wave moves through is called a _medium_
