Here i state the conservation of energy rule and use that to justify my answer. I showed how to manipulate percentages to get the final answer of 11000J (2sf). Hope I'm right xx
Answer:
The mass will accelerate. Balanced Forces: When forces are in balance, acceleration is zero. Velocity is constant and there is no net or unbalanced force. A plane will fly at constant velocity if the acceleration is zero.
Explanation:
True. The 7 colors, also called a rainbow, are red, orange, yellow, green, blue, indigo, and violet. This rainbow is formed because the prism bends the white light and spreads it out into the colors it was made of. If there is more you were looking for, comment here.
Answer:
The phase difference between waves 31.7 rad
Explanation:
Given :
Wavelength 
m
Separation between two slit 
m
Angle 
25°
From the formula of phase difference,
Where 
phase difference
rad
Therefore, the phase difference between waves 31.7 rad
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.
