|acceleration| = (change in speed) / (time for the change)
= (10 m/s - 0) / (4 s)
= (10 / 4) (m/s²)
= 2.5 m/s² .
The direction of the acceleration is west.
Kinetic energy because there is motion (PE converting to KE). Potential energy is the amount of stored energy.
We know the equation for calculation of speed of sound at temperature:
<span>v = 331 m/s + (0.6 m/s/C) * T
</span>Here, T = 30 C
v = 331 m/s + (0.6 m/s/C) * 30 C
v = 331 m/s + 18 m/s
v = 349 m/s
In short, Your Answer would be 349 m/s
Hope this helps!
Answer:
Explanation:
We can use kinematics equation .
What we're given:
- of 100.0 m/s
- of 12 s
- of -8.0
Solving for :
<h3>
♫ - - - - - - - - - - - - - - - ~Hello There!~ - - - - - - - - - - - - - - - ♫</h3>
➷ Use this equation:
Q = IT
Rearrange for I
I = Q/T
Substitute in the values:
I = 240/3
I = 80
The electric current is 80 amps.
