A. Illustrates how a theory becomes a law
I got inner ear for my answer if wrong sorry
Hi there!
We can use impulse for this situation:
I = Δp = mΔv
Impulse = Force × time, so:
I = 63.9(24) = 1533.6 Ns
Find force by dividing by time:
I/t = 1533.6/1.2 = 1278 N
Answer:12,352 cal
Explanation:
Given
to change 16 gm ice at 
First we need to take ice to 
then change its state to water and then raises water temperature from 0 to 
.
After it change water phase to steam and then raise its temperature to 
+
Q=12,352 cal
The speed of sound really depends on the temperature and moisture in the air,
and the sound of the thunder doesn't necessarily travel straight from the lightning
to where you are. So we can't say exactly.
But if we use the nominal speed of 340 m/s, then 6 seconds means 2,040 meters,
or about 6,700 feet, or about 1.27 miles.
