Explanation:
Given that,
Power drawn by the refrigerator = 20 watt
Power of burning light inside = 20 watt
Room temperature = 27°C
We need to calculate the temperature
Using formula of coefficient of refrigerator
Put the value into the formula
is less than 
Therefore, refrigerator cools its interior below room temperature while the bulb is on.
Hence, This is the required solution.
Unit is m^3 or metres cubed. You need to multiply the three dimensions of the block to get the volume.
A ruler can be used to measure the edges.
Answer:
Explanation:
Lower the refractive index , higher the wave length
Refractive index becoming high reduces the velocity and hence wavelength as frequency remains unchanged.
So refractive index 1.4831 will correspond to wavelength of 450 nm.
For refractive index is 1.4831 , angle of incidence i , angle of refraction r .
Sin i / Sinr = 1.4831
sin65 / sinr = 1.4831
sir r = sin65 / 1.4831
= .9063 / 1.4831
= .6111
r = 37.67 degree
For refractive index is 1.4754 , angle of incidence i
Sin i / Sinr = 1.4754
sin65 / sinr = 1.4754
sir r = sin65 / 1.4754
= .9063 / 1.4754
= .61427
r = 37.9 degree
angle between two refracted ray
37.9 -37.67
= 0. 23 degree
Answer:
kinetic energy increases with the energy which causes the particles to move faster resulting in increases collision rates and rate of diffusion.
