A car is built from various subsystems. If these subsystems are not working properly it is dangerous because it can cause a serious traffic accident.
<h3>What subsystems do cars have?</h3>
When you're testing the build of a car, you have to check its many subsystems:
- the battery
- the engine
- the cabin
- the thermal-management system
- the gearbox
- the chassis
- the suspension
<h3>Why is a car with damaged subsystems dangerous?</h3>
The subsystems of a car are very important components that allow the proper functioning of the car. These subsystems work synchronously making the car work properly.
However, if one of these subsystems is not working properly it could cause a malfunction that could lead to a traffic accident.

Answer:
497.00977 N
3742514.97005
Explanation:
= Density of water = 1000 kg/m³
C = Drag coefficient = 0.09
v = Velocity of dolphin = 7.5 m/s
r = Radius of bottlenose dolphin = 0.5/2 = 0.25 m
A = Area
Drag force

The drag force on the dolphin's nose is 497.00977 N
at 20°C
= Dynamic viscosity = 
Reynold's Number

The Reynolds number is 3742514.97005
Answer:
Explanation:
We can use the conservation of the angular momentum.


Now the Inertia is I(professor_stool) plus mR², that is the momentum inertia of a hoop about central axis.
So we will have:

Now, we just need to solve it for ω.

I hope it helps you!
Explanation:
Recall the equation for time is distance divided by speed. Here you can use that to solve for "t".
