Answer:
Option D. 23.5 m
Explanation:
From the question given above, the following data were obtained:
Frequency = 200 Hz
Speed of sound in brass = 4700 m/s
Wavelength of sound in brass =?
We can obtain the wavelength of the sound in the brass by using the following formula as illustrated below:
Wave speed = wavelength × frequency
4700 = wavelength × 200
Divide both side by 200
Wavelength = 4700 / 200
Wavelength = 23.5 m
Thus, the wavelength of the sound in the brass is 23.5 m
To see if the insulation would affect the temp of whatever you are measuring. <span />
Answer:
a) 
, b) 
Explanation:
a) According to the Principle of Energy Conservation, the kinetic energy of the box is transformed into elastic potential energy.
The spring constant is:
b) The initial speed needed to compress the spring by 1.5 centimeters is:
They can be the same shape & size but they can have different mass. And mass is density so if they have different masses then they have different densities.
MASS=DENSITY
nuclear energy is found in the nucleus of an atom
thermal energy is found when internal energy is transferred
Electrical energy is found in the flow of electrical charges
Chemical energy is found in the bonds between atoms
