Answer:
silver
Explanation:
It is because it contains a higher number of movable atoms ( free electrons)
So we want to know what is the resistance of the ceiling fan if the current I=0.625 A and the voltage V=120 V. So we can get the resistance from Ohms law: I=V/R where I is the current, V is voltage and R is resistance. So the resistance is R=V/I. Now we input the numbers and get: R=120/0.625=192 Ω. That is resistance to the closest whole number.
Answer:
Explanation:
Snell's law for index of refraction of a medium is as follows .
sin i / sin r = μ
i is angle of incidence , r is angle of refraction and μ is refractive index.
sin r = sin i / μ .
As μ for blue light is greatest , angle of refraction for blue light will be least . Similarly , angle of refraction will be maximum for red light .
So maximum deviation in the direction of light will occur in blue light due to least angle of refraction because
deviation angle = angle of incidence - angle of refraction .
So the order of light from inward towards surface
= blue , green , red .

Answer: (b)
Explanation:
Given
Mass of box 
Applied force 
Friction force 
Box travels a distance of 
time taken 
Net unbalanced force 
Work done by the unbalanced force
Power developed by unbalanced force
Thus, option (b) is correct.
