You are correct. Mountains are part of the lithosphere.
The minimum coefficient of static friction between the pavement and the tires is 0.69.
The given parameters;
- <em>radius of the curve, r = 90 m</em>
- <em>angle of inclination, θ = 10.8⁰</em>
- <em>speed of the car, v = 75 km/h = 20.83 m/s</em>
- <em>mass of the car, m = 1100 kg</em>
The normal force on the car is calculated as follows;

The frictional force between the car and the road is calculated as;

The net force on the car is calculated as follows;


Thus, the minimum coefficient of static friction between the pavement and the tires is 0.69.

"Q = ΔU + W" is the equation is used to solve the questions related to "First law of thermodynamics".
<h3> What is the first law of thermodyanamics?</h3>
"First law of thermodynamics" states that "energy" neither created nor destroyed, but it can transfer from "one form of energy" to "another form of energy".
This "First law of thermodynamics" is also called as "law of conversation of energy". The formula for "First law of thermodynamics" of a system is that "change in internal energy of a system" is same as the difference of "heat energy" flows across the " boundaries of a system" and the "work done" on the system.
ΔU = Q - W
Q = ΔU + W
Where, "ΔU" is "change in internal energy", "Q" is "heat transferred and "W" is "work done.
Hence "Q = ΔU + W" is the equation is used to solve the questions related to "First law of thermodynamics".

If the group of all forces acting on an object is balanced,
then the effect of all of them is the same as if there were
no forces at all on the object. In that case, the object
continues moving in a straight line at a constant speed.
