The potentially harmful effects of mining can be reduced by A. Flushing mines with water.
Well, it goes 60 miles in one hour......so set up a ratio.....
60 miles/5 miles = 1 hr/x.....you'll get 60x = 5....then 5/60 would be 0.083
Yes it is possible to add sound to a system to make it quieter
Hi there!
Recall the conservation of momentum for an inelastic collision:

Remember, velocity is a VECTOR and direction must be accounted for. Let the 1000 kg car have a positive velocity and the 1500 kg car have a negative velocity (opposite direction).
Plug in the given values:

Solve:

An Ammeter is actually connected:
d. It is in series with the circuit.
So it can read the current flowing through the circuit.
