Answer:
New length = 10.2 m
Explanation:
Let ΔL = change in length
ΔT = change in the temperature
L(0) = intial length
α = coeffient of linear expansion
Then
ΔL = αL(0)ΔT
=(2.4×10^-5)(10)(100-20)
=0.0192 m
New length = L(0) + ΔL
= 10 + 0.0192
= 10.2 m
I remember this from IPC! If farmers used reclaimed water, there is a chance of chemical contamination in the water can damage the plants, if not kill them entirely! :D
Other characteristic of radiation is the presence of positive and negative charge.
<h3 /><h3>What other characteristic does the radiation have?</h3>
Positive or negative charge are the other characteristic that is present in the radiation. Beta radiation have negative charge while on the other hand, alpha radiation have positive charge.
So we can conclude that other characteristic of radiation is the presence of positive and negative charge.

When the image of an object is seen in a plane mirror, the distance from the mirror to the image depends on the distance from the object to the mirror.
It is because a Plane Mirror is the incident ray, the reflected ray, and the normal to the surface all lie in the same plane, and the angle of incidence is equal to the angle of reflection. So, the distance from the object to the mirror equals the distance from the image to the mirror. Thus whoever the person viewing this image must sight at this image location.
<span>Rigel has a much greater absolute magnitude than Sirius, but appears to be much dimmer. This is due to the fact that Rigel is about one hundred times further away than Sirius. Sirius is a much lower energy star, but appears to be the brightest star in the sky because of its relatively close proximity of 8 light years.</span>
