Answer:
The reaction force from the shaft, which keeps the wheels in place during operational rotation
Explanation:
The pinwheel design which has the same principle of a turbine, relies on a external energy source such as the wind or water to provide motive force for spinning
Whereby the reaction force provided by the shaft holding the wheel is non existent or insufficient, the wind will be able to push the wheel in its direction thereby giving the wheel only a net translation and no rotation.
The answer is B. I don’t think I need to explain this,
Mean is average, Mode is the most common number, and Median is the middle number when you put the numbers is numerical order from least to greatest

Explanation:
There is some evidence that regular static stretching outside periods of exercise may increase power and speed, and reduce injury. The best time to stretch is when the muscles are warm and pliable. This could be during a yoga or pilates class, or just after exercising.
Answer:
a = 6.31 m/s²
Explanation:
a) The acceleration of the car can be found using the Newton's second law:
<u>Where:</u>
F: is the net force acting on the car
m: is the mass
a: is the acceleration of the car
W: is the weight of the car
θ: is the angle = 40.0°
g: is the gravity = 9.81 m/s²
Hence, the acceleration is:
Therefore, the acceleration of the car is 6.31 m/s².
I hope it helps you!
