Answer:
true,true,false
Explanation:
its false because if it is equal it would show an arrow pointing left and a 20 and the same for the right
The answer is Air Resistance
Answer:
Find answers below.
Explanation:
Given the following data;
Voltage = 220V
Current = 15 A
a. To find the power;
Power = current * voltage
Power = 15 * 220
Power = 3300 Watts
b. To find the energy;
Time = 8 hours = 60 * 60 * 8 = 28800 seconds
Energy = power * time
Energy = 3300 * 8
Energy = 26400
Energy = 26.4 Kwh
c. Cost = 13 cents
Cost = 13 * 31 * 26.4
Cost = 106392 cents
(E=mc^2)

<u>And c is a constant for speed of light</u>
Mass of base ball = 0.25kg
Time = t = 0.0075/s
Force = F = 18,500N
Impulse = J = ?
Formula = Impulse = Force x time
= 18,500x0.0075
= 138.75 N-S
