5. Ultraviolet rays are potentially harmful to us primarily due to their A. intensity
B. high frequency.
C. long wavelength.
D. amplitude.

A

Explanation:

Ultraviolet light occurs after white light;

Do you know why gamma rays are harmful because of their high frequency and short wavelength leading to high intensity.

Though the frequency is higher than that of white light, its because of its intensity.

Ultraviolet rays comes handy from depletion of the earth's ozone layer

Hence harmful Ultraviolet rays from the sun attacks the skin Leading to Sun burn and other things.

  distance on the y-axis and time on the x-axis.

explanation:

the instantaneous velocity = change in position/time taken

the slope of the graph should give instantaneous velocity.

  slope of a graph = change in value of y -axis / change in values of x -axis

  comparing both the equations

    change in value of y -axis = change in position

  change in values of x -axis = time taken

so position values should be on the y axis and time values should be on the x axis.

distance on the y-axis and time on the x-axis.

its a 5.5 n
