Explanation:
I = 120/30=2A
Voltage across R3= current × resistance
= 2A × 15 ohm = 30 volt
Types of Air Resistance: There are three main types of drag in aerodynamics – Lift Induced, Parasitic, and Wave. Each affects an objects ability to stay aloft as well as the power and fuel needed to keep it there.

The particles in diagram 3 move fast enough to break away from each other.
Answer:
Explanation:
Initial momentum
4.0(9) + 2.0(-9) = 18 kg•m/s
final momentum
4.0(-3) + 2.0(15) = 18 kg•m/s
Initial kinetic energy
½4.0(9²) + ½2.0(-9²) = 243 J
final kinetic energy
½4.0(-3²) + ½2.0(15²) = 243 J
