The amplitude and wavelength are measured in meters while frequency is measured in decibels.
<h2>
Units of measurement:</h2>
- Amplitude: It is the maximum displacement of the points of the wave from its mean position. Hence it is measured in meters.
- Frequency: It is measured in Hertz. A hertz is a number of waves passed from a single point per second.
- Wavelength: It is the distance between two consecutive crests or troughs. hence it is measured in meters.
- Wave speed: It is measured in m/s.
- Loudness: The loudness of the sound is measured in decibels.
Therefore, the amplitude and wavelength are measured in meters while frequency is measured in decibels.

Explanation:
the process by which heat or electricity is directly transmitted through the material of a substance when there is a difference of temperature or of electrical potential between adjoining regions, without movement of the material.
The idea of a mechanical device, like a wind up toy, is to take take advantage of the laws of thermodynamics in order to perform some kind of work.
In the case of a wind up toy, mechanical energy (winding the handle) is stored as potential energy in an internal spring. This creates a state of 'low entropy' in the toy since work was done to concentrate energy in the spring.
The natural tendency of the spring is to unwind and distribute it's energy in a more disordered fashion, thereby increasing entropy and following the laws of thermodynamics.
The mechanism inside the toy is engineered to focus the flow of energy being delivered by the spring into a specific mechanical motion (Kinetic Energy), then sound (air pressure) and finally heat (thermal energy).
To solve this problem we will apply Newton's second law for which weight is defined as the product between mass and acceleration of gravity. That is to say
Here,
m = mass
g = Gravitational acceleration
If we have that 0.22lb is equal to 1N, then the weight will be
Gravitational force is equal to , then
Therefore the mass of the car is 1320.5Kg
Answer:
B) 0.0456
Explanation:
It is given that :
Rationale :
UCL = 480
LCL = 480
∴ Mean ,
The standard deviation of sample (Sn) = 11.55
Z (for UCL)
= 2
Similarly,
Z (for LCL)
= -2
Now using the z table for finding the confidence level between Z value of -2 and 2.
Confidence level = 0.4772 + 0.4772
= 0.9544
Risk (alpha) = 1 - confidence level
= 1 - 0.9544
= 0.0456
