To determine
Why ultraviolet
Expert Solution & Answer
Answer to Problem 2CQ
The ultraviolet rays have enough energy to ionize the atoms and molecules in the skin but visible light do not have enough energy for ionization.
Explanation of Solution
The photon model of light connects the energy of light to its frequency only. The ultraviolet rays have more energy than the visible photons due to the high frequency of the ultraviolet rays than the visible light. Due to the high energy they can cause more damage to the skin.
The ionizing power of the high frequency ultraviolet rays is more. The can ionize skin molecules and atoms causing harm to the skin. The visible light of higher frequency does not have the enough energy for ionization. Therefore, the ultraviolet rays has enough energy to ionize the atoms and molecules in the skin but visible light do not have enough energy for ionization.

Consider the situation in the figure below; a neutral conducting ball hangs from the ceiling by an insulating string, and a charged insulating rod is going to be placed nearby.
A. First, if the rod was not there, what statement best describes the charge distribution of the ball?
1) Since it is a conductor, all the charges are on the outside of the ball. 2) The ball is neutral, so it has no positive or negative charges anywhere. 3) The positive and negative charges are separated from each other, but we don't know what direction the ball is polarized. 4) The positive and negative charges are evenly distributed everywhere in the ball.
B. Now, when the rod is moved close to the ball, what happens to the charges on the ball?
1) There is a separation of charges in the ball; the side closer to the rod becomes positively charged, and the opposite side becomes negatively charged. 2) Negative charge is drawn from the ground (via the string), so the ball acquires a net negative charge. 3)…

- Hello, I need some help with calculations for a lab, it is Kinematics: Finding Acceleration Due to Gravity. Equations: s=s0+v0t+1/2at2 and a=gsinθ. The hypotenuse,r, is 100cm (given) and a height, y, is 3.5 cm (given). How do I find the Angle θ1? And, for distance traveled, s, would all be 100cm? For my first observations I recorded four trials in seconds: 1 - 2.13s, 2 - 2.60s, 3 - 2.08s, & 4 - 1.95s. This would all go in the coloumn for time right? How do I solve for the experimental approximation of the acceleration? Help with trial 1 would be great so I can use that as a model for the other trials. Thanks!arrow_forwardAfter the countdown at the beginning of a Mario Kart race, Bowser slams on the gas, taking off from rest.
