<em>Hello, </em>
<h3><u>QUESTION)</u></h3>
According to the second Newton's Law,
<em>✔ We have : F = m x a ⇔ m = F/a </em>
The mass of the object is therefore 200 kg.
Electrons have a negative charge, so if you give away electrons, you give away negative charge, thus ending with a positive charge.
T=2s
g=10m/s2
h=?
free fall: h=gt2/2
h= 10*4/2
h=40/2
h=20m
<span>The repelling of the support magnet decreases friction. is the answer you're looking for . :)
