Heat always flows from warmer objects to cooler objects.
That's the reason why, if you want to cool your soda, you
drop an ice cube into it, and not a red hot iron horseshoe.
Answer:False
Explanation:Sound waves need a mediun
Using the formula t=root of 2h/g then where h=28 and g=9.8 then substitute so the answer is 2.4seconds
Hello!
Use the formula:
M = k * p
Data:
M = Mechanic energy
k = Kinetic energy
p = Potencial energy
Descomposing:
M = (0,5*mv²) + (mgh)
Replacing:
M = (0,5 * 59,6 kg * (23,4 m/s)²) + (59,6 kg * 9,81 m/s² * 44,6 m)
M = 16317,28 J + 26076,54 J
M = 42393,82 J
The mechanic energy is <u>42393,82 Joules.</u>
Here's a explanation!
Let's solve your equation step-by-step.
Step 1: Multiply both sides by x.
(Divide both sides by 4).
Take the root.
