<h2>
The car tire makes 149 revolutions before coming to stop.</h2>
Explanation:
a) We have equation of motion v² = u² + 2as
Initial velocity, u = 32.4 m/s
Acceleration, a = -1.70 m/s²
Final velocity, v = 0 m/s
Substituting
v² = u² + 2as
0² = 32.4² + 2 x -1.70 x s
s = 308.75 m
Distance traveled before stopping is 308.75 m
Radius of tire = 0.330 m
Circumference of tire = 2πx 0.33 = 2.07 m
1 revolution = 2.07 m
The car tire makes 149 revolutions before coming to stop.

We take the derivative of Ohm's law with respect to time: V = IR
Using the product rule:
dV/dt = I(dR/dt) + R(dI/dt)
We are given that voltage is decreasing at 0.03 V/s, resistance is increasing at 0.04 ohm/s, resistance itself is 200 ohms, and current is 0.04 A. Substituting:
-0.03 V/s = (0.04 A)(0.04 ohm/s) + (200 ohms)(dI/dt)
dI/dt = -0.000158 = -1.58 x 10^-4 A/s
You should allow the ventilation system to run for at least four minutes before starting the engine. This is necessary in order to allow the odour of the fuel to be blown away by the blower. After ventillation for four minutes you must re-check for the smell of the fuel. The boat should not be operated yet if the fuel odor is still very strong.
