Answer:
192 mm/s
Explanation:
The frequency, speed and wavelength of any given wave are related to one another by the formula;
fλ = v
Where f denotes the frequency, v the speed or velocity and λ the wavelength
We are given that;
λ = 12
f = 16
v = 16 * 12 = 192 mm/s
Answer:
a)
b)
c)
The estimate is low.
Explanation:
a) Using the energy conservation we have:

we have kinetic energy intially and gravitational potential energy at the maximum height.


b) We can use the equation of the gravitational force
(1)
We have that:
(2)
at the surface G will be:

Now the equation of an object at a distance x from the surface.
is:


Using that dv/dt is vdx/dt and integrating in both sides we have:



c) The difference is:
So the percent difference will be:


The estimate is low.
I hope it helps you!
Answer:
A.ENERGY: Radio<microwaves<infrared<visible light<ultraviolet<xrays<gammarays
B. WAVELENGTH: Radio>microwaves> infrared>visible light>ultraviolet>xray> gammarays
C. FREQUENCY: Radio<microwaves<infrared<visible light<ultraviolet<xray< gammarays
Explanation:
THIS IS BECAUSE OF THE FOLLOWING EQUATIONS
1.ENERGY (E)= hX freqency
So as energy of radiation increases frequency also increases
2. Velocity (v) = wavelength x frequency
So as wavelength increases frequency decreases and vice versa
Answer:
Height of the cube under water will be 3.33 cm
Explanation:
We have given height of the cube = 5 cm
Density of the material 
Density of liquid 
We have to find the height of the cube under the water
Height under water is given by
Height under water = 
Height of the cube under water will be 3.33 cm
