Answer:
2.5 ms⁻²
Explanation:
By Newton's 2nd law,
The rate of change of momentum is directly proportional to the unbalance force applied on the object,
By that you can get the equation,
F = ma ⇒ a = F/m
where terms are in usual meaning
a = 3750/1500 = 2.5 ms⁻²
And think they are high energy waves. But I'm not sure
A= 50/8 m/s^2
<span>vf=at=50/8 * 5= 250/8 m/s at t=5sec </span>
<span>time to get to 50m/s </span>
<span>50=50/8*t or t=8 seconds </span>
<span>distance=1/2 a t^2=1/2 50/8 64 </span>
<span>distance= 400 m check that.</span>
Answer: 18000 coulombs
Explanation:
Given that:
Current, I = 5.0A
Electric charge Q = ?
Time, T = 1 hour
(The SI unit of time is seconds. So, covert 1.0 hour to seconds)
If 1 hour = 60 minutes and 60 seconds = 1 minute
Then, 1.0 hour = (60 x 60)
= 3600 seconds
Since electric charge, Q = current x time
i.e Q = I x T
Q = 5.0 A x 3600 seconds
Q = 18000 coulombs
Thus, 18000 coulombs of charge flows through the lamp in this time.
