(A) power loss due to air resistance is Apus
(B) power loss due to air resistance is Apus
(C) drag force is Apu?
(D) drag force is Apu?​

Answer 1

Answer:

thankyou

Explanation:

Suppose a car is modelled as a cylinder moving with a speed v. If A is the area

of cross-section of the car and p is the density of air then

(A) power loss due to air resistance is Apus

(B) power loss due to air resistance is Apus

(C) drag force is Apu?

(D) drag force is Apu?

Answer 2

Answer:

The correct answer is:

(A)Power loss due to air resistance is Apv^3/2

(B) drag force is Apv^3/2

Explanation:

Car is modelled as a cylinder moving with a speed v.

If A is the area of cross section of car and p is the density of air then the

Power loss due to air resistance is Apv^3/2 and drag force is Apv^3/2.

The power P=IV

Here power is P, I is the current, V is voltage.

I is the flow of charge per unit time.

Also P=V^2/R.

where R is resistance.
