Answer:
1000 N
Explanation:
An impulse results in a change of momentum
FΔt = mΔv
F = 0.001 kg(1000 - 0) m/s / 0.001 s = 1000 N
Answer:
Kinetic energy and momentum are conserved.
Explanation:
Voltage is the difference in charge between two points.
Current is the rate the charge flows
Resistance is the tendency a material has to resist the flow of charge (current)
Combining voltage resistance and current Ohm developed the formula
V (Voltage)= I (Current) x R (Resistance)
Explanation:
Trees, because of their height, are natural lightning rods. Electricity seeks the path of least resistance, and the moisture inside a tree is a much better conductor than air. This means a tree provides the preferred path for lightning to reach the ground.
0.0605J is your answer. Use the formula KE=1/2mv^2
