Answer:
Explanation:
Angular acceleration is defined as the variation of angular speed with respect to time:
The relation between the angular speed and the linear speed is given by:
Replacing (2) in (1):
We need to convert 
to 
:
Recall that:
Replacing:
Answer: The visible part of the electromagnetic spectrum, <u>specifically blue and red wavelength</u>
Explanation:
Let's begin by explaining that pigments generally absorb more light than they reflect (they absorb certain wavelengths and reflect others). Therefore, the color that a given object seems to have depends on which parts of the visible electromagnetic spectrum are reflected and which parts are absorbed.
In this sense, in the thylakoid membranes there are two types of <u>chlorophyll pigments</u>:
-clorophyll b that absorbs the blue light of the electromagnetic spectrum
-clorophyll a that bsorbs the red light of the electromagnetic spectrum
That is why we generally see plants in green color and not in other colors.
Answer:
A real image is formed on a cinema screen.
Explanation:
It is a type of image that is formed when light rays coming from an object meet each other in actual after reflection or refraction. A real image can be easily obtained on the screen. It is always inverted
To have a force of 3.8x10-8 the two chaarges must be 0.65m apart.
The reaction force is the glove pushing against the ball because the reaction force would be the ball pushing onto the glove.
Hope that helps :)
