Explanation:
Equation for Impact
FΔt = ΔP,
F = force
Δt = Impact of time
ΔP = Change in momentum
Car steering is engineered to fail in order to maximize the time of contact and hence reduce the initial impact and mitigate the damage incurred.
Road guard railing crumple on contact to maximize impact time and hence reduce impact intensity and mitigate damage.
Road safety containers are loaded with liquid or sand as they improve the period of impact.
A revolution equals 2*pi radians.
As the wheel rotates half every 4 seconds, then it means that it rotates half revolution.
Thus, the angular velocity of the wheel is given by:
w = (pi) / (4) = 0.79 rad / sec
answer
The wheel's angular velocity is 0.79 rad / sec
Answer:
Your answer is B.!
When things in general get hotter, the atoms inside move faster and vise versa with cold.
(for example water); if you put water in a pot on a stove to boil, its gets so hot to where the atoms are moving really fast to get it to look like that.
Please mark brainiest! if this answer is wrong, (which I'm pretty sure it isn't) then pick D. :D
Answer:
Internal energy will be
Explanation:
We have given that initial volume
And final volume
Pressure
Now change in volume
We know that change in internal energy is given by
, here we know that
Work done
So
