Answer:
E. The momentum of the car-truck system is conserved, but the momentum of each one separately is not conserved.
Explanation:
Answer:
0.256 m/s
Explanation:
Speed is distance over time.
Find the speed of each trial and then find the average.
Trial 1: v = 0.7 m / 2.5 s = 0.280 m/s
Trial 2: v = 0.7 m / 2.75 s = 0.255 m/s
Trial 3: v = 0.7 m / 2.98 s = 0.235 m/s
v_avg = (0.280 m/s + 0.255 m/s + 0.235 m/s) / 3
v_avg = 0.256 m/s
Round as needed.
Answer:
The magnitude of charge on each sphere is .
Explanation:
Given that,
Force of repulsion between the charges, F = 22 mN
The distance between spheres, r = 16 mm = 0.016 m
It is mentioned that both the spheres carry equal charges. The force between charges is given by :
So, the magnitude of charge on each sphere is . Hence, this is the required solution.
It is possible. If you trap it in a certain space, it will be possible.
Answer:60mph means it runs every minute.
Explanation: because it makes sense.
