Answer:
the acceleration of the car is 5m/s2
Answer:
Explanation:
If a perfect vacuum existed in any volume, then no sound would be able to propagate through it, because a sound wave is a pressure wave, and there would be identically zero pressure. Of course, we could get into speculations about “dark energy” or “vacuum energy” supporting pressure waves, but let’s not go there.
Well, I'm not sure right now that it actually does.
But if it does, that's because the sun is about 400 times
FARTHER from the Earth than the moon is.
<h3><u>Answer;</u></h3>
= 21600 Joules or 21.6 Kilo joules
<h3><u>Explanation;</u></h3>
Electrical energy is given by the formula = VIt ;
where V is the voltage in volts, I is the current in Amperes, and t is time in seconds.
Voltage = 120 volts
Current = 3 amperes
Time = 60 seconds or 1 minute
Therefore;
Electrical energy = 120 × 3 × 60
<u> = 21600 Joules or 21.6 Kilo joules</u>
