<span>1g=32 ft per second ^2
62.6=330528ft
62.6 miles per hour =330528ft perhour=(330528ft perhour/3600seconds per hour)=91.8ft per second
formula for the velocity (v(t))in feet per second at time t in seconds :
v(t))=224t+v0,v0=initial velocity = 0ft per seconds
v(t))=224t
224t =91.8
t=0.409seconds</span>
Answer: Rub the rod with a piece of metal that is already magnetized. Or
Rub the rod with two magnets, drawing the north pole of one magnet from the center of the rod to one end while you draw the south pole of the other magnet in the opposite direction.
Explanation:
Answer:
The charge is
Explanation:
From the question we are told that
The mass of each ball is
The distance of separation is
Generally the weight of the each ball is mathematically represented as
where g is the acceleration due to gravity with a value
substituting values
Generally the electrostatic force between this balls is mathematically represented as
given that the the charges are equal we have
So
Now from the question we are told to find the charge when the weight of one ball is equal to the electrostatic force
So we have
=>
