Answer:
hearing range for a healthy young person is 20- 20,000 hertz. The highest frequency for a normal middle aged man is 12-14 kilohertz.
Answer:
Part a)
Moment of inertia of the cylinder is given as
Part B)
Height of the cylinder is of no use here to calculate the inertia
Part C)
Since we don't know about the viscosity data of the soup inside the cylinder so we can't say directly about the moment of inertia of the cylinder as
Explanation:
As we know that the inclined plane is of length L = 3 m
and its inclination is given as 25 degree
so we know that acceleration of center of mass of the cylinder is constant so we will have
so we have
now we know that
Now we have know that final speed of the cylinder due to pure rolling is given as
Part B)
Height of the cylinder is of no use here to calculate the inertia
Part C)
Since we don't know about the viscosity data of the soup inside the cylinder so we can't say directly about the moment of inertia of the cylinder as
The answer to this question should be a gravitational force.
A gravitational force is something that sort of attracts two things of mass. This force must never ever pull the objects of mass apart. It must always try to pull them together. So, judging by the question we can tell that the two masses in this situation are the leaf and the ground. When the leaf fell on the ground this was the gravitational force pulling the leaf down so it connects with the ground.

I think you wrote 4900 twice so will use that as the distance. To solve this it is helpful to draw a picture. The drawing should be of a triangle. Since the driver is driving up at an angle, the 4900 ft will be the hypotenuse of the triangle. since we do not know the values of the other two sides of the triangle we cant solve for the altitude using Pythagorean theorem but we can solve using the sine function on our calculator. As sine of angle is equal to opposite over hypotenuse(sinθ=opposite/hypotenuse). Having θ and the hypotenuse we can solve for opposite or the altitude. using some algebra we get hypotenuse*sinθ=opposite or altitude. now to plug everything in and solve: 4900 ft*(sin(2°))=opposite or altitude=171 ft
