We are given the coefficient of friction which is:
Cf = 0.90
The acceleration based on this would be:
a = -Cf * g
a = -0.90 * (9.81 m/s^2)
a = -8.83 m/s^2
Calculate the distance at his total stop v = 0 using the formula:
v^2 = vo^2 + 2ad
where v is final velocity = 0, vo is initial velocity = 16, d is distance
0 = 16^2 + 2 (-8.83) d
d = 14.5 m
So he is short by 0.5 m, he does not reach the finish line
Answer:
The positive sign indicates that work is done by the gas.
Explanation:
Let consider that gas inside the cylinder behaves ideally and process is isothermal, so that change in internal energy can be neglected. The engine cylinder is modelled after the First Law of Thermodynamics:
The positive sign indicates that work is done by the gas.
<span>An imaginary line perpendicular to a reflecting surface is called "a normal" (principle line)
So, Your Answer would be Option B

Answer:
Flooding of roads near the coast
Explanation:
-Storms surges have the potential to harm lives and property via storm surge, heavy rain or snow causing flooding or road impassibility, lightning, wildfires, and vertical wind shear.
-The significantly high amounts of rainfall during storms leads to flooding of coastal regions , roads included thus rendering them impassable.
The formula for resonant frequency is:
Given information:
Plug in the given values to find one value of capacitance:
Plug in the given values to find the other value of capacitance:
This gives a range of 2.429 nF to 26.45 nF.
With significant figures taken into account, the range of capacitance is 2.43 nF to 30 nF.
