<span>Since forces are vector quantities, we must indicate direction using positive and negative values. East will be assigned positive and west will be negative. Friction will act as a negative force since it impedes action. To calculate the net force we sum the vector quantities, as follows. Net force equals 50n which is derived by the following calculation: 300n-220n-30n.</span>
I believe the answer should be the last option. upon interaction, both objects should have the same charge after the electrons are transferred.
Weight = mass * gravity = 60 kg * 3.75 m/s² = 225 N
<span>Option D.</span>
First is melts then it expands next it gets cooler Finally it gains ener. Hope this helps you out.
Mass is measured in kg
Velocity is measured in ms^-1
Hope this is what you were looking for
