Answer:air flow and the movement from where it’s coming from
Explanation:
Yes they do. So if you need to add or subtract a pair, then you have to first change one or the other so that they both have the same power of 10.
Answer: A. Superconductor
Explanation:
Ground-Fault Circuit Interrupter
, Fuse, Circuit Breaker cause the circuit to break when high amount of current flows through it; thereby protecting any electrical accidents. A superconductor has zero resistance. It gives an easy path for an amount of electricity to flow through it. Thus, it would not prevent electrical accidents.
Answer:
Explanation:
Use the equation
where h(t) is the height after a certain amount of time goes by, v0t is the initial upwards velocity, and h0 is the initial height of the projectile. For us:
h(t) = 10
v0t = 80
h0 = 3 and filling in:
and get everything on one side to factor:
This factors to
t = .09 sec and 4.9 sec. Let's interpret this.
The time of .09 is when the ball reached 10 feet on the way up, and
the time of 4.9 is when the ball reached 10 feet on the way back down. That's the height we need, 4.9 seconds.
