Shrill sound is of -------------- *

Higher frequency
Lower frequency
Higher amplitude
Lower amplitude

Answers

Answer:

Higher frequency.

Explanation:

Sound are mechanical waves that are highly dependent on matter for their propagation and transmission.

Sound travels faster through solids than it does through either liquids or gases. A student could verify this statement by measuring the time required for sound to travel a set distance through a solid, a liquid, and a gas.

Mathematically, the speed of a sound is given by the formula:

[tex] Speed = wavelength * frequency [/tex]

Generally, the frequency of a sound wave determines the pitch of the sound that would be heard.

A shrill sound refers to a type of sound that is typically sharp, high pitched and as such has higher frequency.

Hence, shrill sound is of higher frequency.

A spring is stretched downward by a certain length and, as a result, exerts a
force in the upward direction. What happens to the force exerted by the
spring if the length by which it is stretched is reduced by half?
O A. The force exerted by the spring is reduced by half.
B. The force exerted by the spring is doubled.
O C. The force exerted by the spring reduced by one quarter.
O D. The force exerted by the spring remains unchanged.

Answers

Answer:

A

Explanation:

Hooke's law! F(spring)=-kx

There's no tricky square law here. The spring constant doesn't change, only x (distance stretched) changes. Therefore, if distance is halved, Force will be halved.

Answers

The principle of work and kinetic energy (also known as the work-energy theorem) states that the work done by the sum of all forces acting on a particle equals the change in the kinetic energy of the particle. ... This relationship is generalized in the work-energy theorem.

A weight-lifter raises a 2000 N weight through a vertical height of 2.0m in 0.80 s.
What useful power does he develop in doing this?
A
800 W
B
3200W
с
4000 W
D
5000W

Answers

Answer:

D. 5000W

Explanation:

Given the following data;

Force = 2000N

Distance = 2m

Time = 0.8s

To find the power;

First of all, we would determine the workdone by the weightlifter

Workdone = force * distance

Workdone = 2000 * 2

Workdone = 4000N

Now, we can find the power using the formula;

Power = workdone/time

Substituting into the equation, we have

Power = 4000/0.8

Power = 5000 Watts
