Answer:
Explanation:
For this problem we must use Newton's second law where force is gravitational attraction
F = m a
Since movement is circular, acceleration is centripetal.
a = v2 / r
Let's replace
G m M / r² = m v² / r
G M r = v²
The distance r is from the center of the planet
r = R + h
v = √ GM / (R + h)
If the friction force is not negligible
F - fr = m a
Where the friction force must have some functional relationship, for example
Fr = b v + c v² +…
Suppose we are high enough for the linear term to derive the force of friction
G m M / r - (m b v + m c v2) = m v2
G M / r - b v = v²
We see that the solution of the problem gives lower speeds and that change over time.
To compensate for this friction force, the motors should be intermittently suspended to recover speed.
The correct answer to this question is : C) Conduction
EXPLANATION:
Before coming into any conclusion, first we have to understand conduction.
Conduction is the mode of transmission of heat in which heat will flow from a body at high temperature to a body at low temperature in contact or from hotter part of the body to its colder part, without any actual transport of particles.
As per the question, the heat is transferred to driver's hand when he touches the steering wheel.
As there is actual contact between hand and steering wheel, the heat transmission will be conduction.
