Answer:
an object sliding down hill
Explanation:
On a slope, the force applied is due to gravity. Its direction is straight down. If the object is sliding down the hill, its displacement is at an angle to the applied force. The angle of displacement will depend on the steepness of the hill.
Force = mass x acceleration
113N = 25.2a
a = 4.48 m/s^2
Vf = Vi + at
Vf = 2.33 + 4.48(2) = 11.3 m/s
Answer:
zero
Explanation:
If the car is moving at a constant velocity then there cannot be any acceleration. Acceleration is any change in velocity over time. If velocity doesn't change, then there is no acceleration.
Answer:
The values of the two resistors are 48 ohms and 12 ohms.
Explanation:
Power (P) = Voltage^2 (V^2) ÷ Resistance (R)
R = V^2 ÷ P
The minimum power drawn by the heater is 300 watts
Voltage is 120 V
R = 120^2 ÷ 300 = 14,400÷300 = 48 ohms
The maximum power drawn by the heater is 1200 watts
R = 120^2 ÷ 1200 = 14,400 ÷ 1200 = 12 ohms
