Answer: a = 1, b = 9, c = 6, d = 4
Explanation:
With no velocity, total mechanical energy is all gravity potential energy
PE = mgh = 80.0(9.81)(25) = 19,620 J = 1.96e4 J
Answer:
5 seconds
Explanation:
Data provided in the question as per the question is as follows
Distance = 1,650 meter
Speed of the sound is 330 m/s
Based on the given information, the time taken is
As we know that

So,


= 5 seconds
We simply divided the total distance from the speed so that the time taken could be come and the same is to be considered
These are the correct answers. I couldn't get the rest of the answers
the answer is earth for the first one and sun for the second one
You haven't told us what any of those letters represents.
I'm going to assume that ...
-- ' P ' = power
-- ' I ' = circuit current
-- ' V ' = circuit voltage
-- ' E ' = energy
-- ' t ' = time.
Now I'm ready to answer the question that I just invented.
P = I / V
V = P x I
Both of these are false statements, and can't be used to calculate anything.
P = I x V is the correct equation to calculate electrical power.
<em>E = P x t</em> is the correct equation to calculate electrical energy.
