Answer:
False
Explanation:
We have never made it to the mantle.
Unlike the one-way flow of energy, matter is recycled within and between ecosystems. Every living organism needs nutrients to build tissues and carry out essential life functions.
Speed of wave = frequency x wavelength
= 250 x 6 = 1500 m/s.
Answer:
E = 75 J
Explanation:
First, we will calculate the total power consumed by the five lamps:

Now, the energy supply can be calculated as follows:

where,
E = Energy = ?
t = time = 5 s
Therefore,
E = (15 W)(5 s)
<u>E = 75 J</u>
A. The sound will decrease in volume
