Answer:
c) The wavelength decreases but the frequency remains the same.
Explanation:
Light travels at different speed in different mediums.
Refractive index is equal to velocity of the light 'c' in empty space divided by the velocity 'v' in the substance.
Or ,
n = c/v.
<u>The frequency of the light does not change but the wavelength of the light changes with change in the speed.</u>
c = frequency × Wavelength
Frequency is constant,
The formula can be written as:
n = λ / λn.
Where,
λn is the wavelength in the medium
λ is the wavelength in vacuum
<u>When the light travels to glass, it speed slows down and also the wavelength decreases as both are directly proportional. There will be no effect on frequency.</u>
Density = mass/ volume
13.6g/cm^3 = m /14.6cm^3
13.6g/cm^3 *14.6 cm^3 = m
198.56g = m
Kinetic energy is equivalent to .5*(mass)*(velocity)^2
The mass should be in kilo grams and the velocity in meters per second.
Let me know if you need more help with it.
Answer:
12
Explanation:
The equation is w= f *d
36=3*d
12=d 12 units is the mass
Answer:
Summary: Nutrition and exercise are critical for improving body composition. Keeping your calories, fiber and protein in check is a good first step. All exercise can help with fat loss, but weight training is the best way to increase muscle mass.
