Answer:
30Km/h
Explanation:
acceleration is the change of speed in a given time so when we substract the accelerations we can know how much the car goes per an hour
As we know that time period of simple pendulum is given as
T = 2π √L/g
V=IR. This is the formula that you can use to figure this question out. Because the voltage stays the same and the current decreases, this means that the resistance has increased.
Answer:
75 km/h
Explanation:
Speed = Distance divided by Time.
The train went a distance of 300 km in 4 hours. Therefore, the speed of the train is: 300 divided by 4 = 75 km/h
