Answer:
<h2>4 N to the right</h2>
Explanation:
<u>The force acting to the right of the body is acting in the positive x direction while the force acting to the left of the body is acting in the negative x direction.</u>
If a force of 12N acts to the left on a body and a force of 16 N acts to the right, force acting to the left will be -12N while that acting to the right will be +16N.
The resultant force acting on the bod will be the sum of the two forces.
Resultant = -12N+16N
Resultant = 4N
<u>The direction of the resultant force will be towards the right since the resultant is a positive value.</u>
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:
<h2>Magnetic field strength in that region is 1.2 T</h2>
Explanation:
As we know by the formula of radius of charge moving in external field is given as
so we will have
now we have
now we have
Since we are only looking at the vertical height, we can use the free fall equation to find the height:
h = 0.5*g*t^2, where h is height in m, g is acceleration due to gravity (9.81 m/s^2), and t is time in seconds
h = 0.5*(9.81 m/s^2)*(3.7 s)^2
h = 67.15 m
Therefore, the 7th floor window is 67.15 m above ground level.
