The relation between the angle of incidence and the angle of refraction is known as Snell's Law. Since the light travels with different speed in different media, the direction of the ray of light will change when it crosses the boundary between the two media
Because of the specific latent heat of fusion or vapourization of the substance
The question is not complete. Kindly find the complete question below:
Host A converts analog to digital at a = 58 Kbps Link transmission rate R = 1.9 Mbps Host A groups data into packets of length L = 112 bytes Distance to travel d = 931.9 km Propagation speed s = 2.5 x 108 m/s Host A sends each packet to Host B as soon as it gathers a whole packet. Host B converts back from digital to analog as soon as it receives a whole packet. How much time elapses from when the first bit starts to be created until the conversion back to analog begins? Give answer in milliseconds (ms) to two decimal places, normal rounding, without units (e.g. 1.5623 ms would be entered as "1.56" without the quotes)
Answer / Explanation
The answer is 19.65
Answer:
power will be quadruples
Explanation:
We know that power in circuit is given by P = VI ,here V is voltage and I is current
Now according to question if we double the voltage and current then power
P will be 
As we know that power is given by P = VI
So new power will be 4 P
So power will be quadruples
