If<span> the </span>speed<span> of the </span>object<span> becomes </span>double<span>, </span>its kinetic energy<span> changes to four times the initial </span>kinetic energy<span>. Hope it help!</span>
0.15m/s^2 i think. Hope it may help.
Answer:
ΔE / E = ΔV / V + Δd / d
Explanation:
The electric field and voltage are related by the expression
E = V / d
The uncertainty of the field is
ΔE / E = ΔV / V + Δd / d
We see that the uncertainty of the field must be added the uncertainty of the distance that in the measure of the different potential has no effect.
The only case in which the uncertainties are equal is if the distance measurement has no uncertainty, or the separation of very high
15 meters due to the fact that gravitational potential energy equals mass times gravity times height.
Explanation:
V= s / t
150 km/hr = 500 km / t
t = 500 km ÷ 150 km/hr
t = 10/3 hr (3 hrs 19 mins 49 sec)?
I'm not sure tho^^
