Answer:
I think it is the forth one
Answer:Whenever a moving object experiences friction, some of its kinetic energy is transformed into thermal energy. Mechanical energy is always transformed into thermal energy due to friction. Mechanical energy is always transformed into thermal energy due to friction.

Answer: B)To the left of the charges.
Explanation: between the charges the electric field will not cancel but will be added since electric field lines from both charges point in the same direction. To the right of the charge the -4q will take over as it’s strength overcomes the strength of the +q charge. At this point the magnitude of +q will never reach a magnitude strong enough to cancel the -4q. To the left, it is further away from -4q and is closer to +q and electric field lines point in different direction
Answer:
orange line
Explanation:
it is the only straight line that makes sense. curved lines imply velocity changed. and the completly flat green line implies the vehicle didn't move since its position value stayed the same. must be the downward pointing orange line
Answer:
0.2 m/s
Explanation:
= Mass of glider A= 0.125 kg
= Mass of glider B = 0.375 kg
= Initial Velocity of glider A = 0 m/s
= Initial Velocity of glider B = 0 m/s
= Final Velocity of glider A = 0.6 m/s
= Final Velocity of glider B
As linear momentum is conserved
Magnitude of the glider B at this time is 0.2 m/s
