F=ma
Force= mass × acceleration
Answer:
In most cases, the electricity source is an outlet, battery, or generator. The power supply works to convert the power from the source into the correct format and voltage. Because a variety of options exist, the specific power supply function depends on whether it needs to regulate energy or convert power.
Answer:
18 000 m/ s
Explanation:
speed = wavelength * frequency
speed = 1.2 * 15 000 = 18 000 m/s
Your answer is a new experiment, since it's something that hasn't been tried before, or has, but resulted in with lots of errors.
For this problem, you would use the equation v=u+at. In this case, u=1 v=0 (when the object is at rest) a=-1
v=u+at
0=1+(-1)t
t=1 second
