Answer:
Ultraviolet light has shorter wavelengths than infrared light. The frequency of ultraviolet light is greater than that of infrared light. Ultraviolet light is higher in energy than infrared light.
Answer
The correct formula for weight is F = m*g where g is the gravitational acceleration.
All over the earth's surface, g is slightly different. The mass does not change no matter where you are. We should be measuring out weights in Newtons, not in kg. So the unit of weight in the metric system is 9.8 about * mass in kg.
Stop reading. This is your answer.

Notes
It was hard enough to get people to change over to kg never mind newtons. Canada, which is on the metric system, still gives the price of food in pounds. Or if not, in grams if the container is small enough.
Cashews cost 19$ Canadian per 906 grams which is roughly 2 pounds.
Oranges are $1.27 a pound and that is the way they are listed in Walmart.
10 pounds of potatoes are 4.95 dollars.
I'm sure you get the point. We use kg for certain things and retain pounds for others.

Explanation:
Answer:
OC The electric force between them decreases.
Explanation:
Electric force is a force due to charges which charged objects exert on each other. The charged objects A and B thus exert a definite force on each other which its value can be varied by varying the distance between them.
It is goo to note that the force between two charges is inversely proportional the the square of the distance between them. Thus when the distance is increased, the electric force would decease.
In the given question, option C is appropriate.
