Answer:
D) diffraction
Explanation:
Corona is an optical phenomenon produced by the diffraction of sunlight or moonlight, as light moves through water droplets in the atmosphere.
This phenomenon produces one or more diffuse concentric rings of light around the Sun or Moon, usually seen as colored circles.
Therefore, the explanation for these phenomena of colored concentric circles, sometimes seen with the Sun or the Moon involves diffraction.
Charge must pass by a point in a wire is 5 Coulomb
Given:
time = 10 s = t
current = 0.50 A = I
To Find:
charge = q
Solution: Current is defined as amount of charge passing through a region per unit time. It is given by the formula
I = q/t
q = I x t = 0.50 A x 10 s = 5 Coulomb
Hence, charge must pass by a point in a wire is 5 Coulomb

<em>When you rub a dry cloth across glass, it creates charged static electricity, which attracts little non-charged dust particles.</em>
The temperature reading in Fahrenheit scale when reading 310 K is 98.6F
<h3>What is temperature?</h3>
Temperature is the degree of hotness or coldness of the object.
Given is a temperature in Kelvin scale = 310 K
Temperature on centigrade scale = 310 -273 = 37°C
Temperature conversion from Centigrade to Fahrenheit is
C/5 = F -32/9
Plug the value, we get
37/5 = F-32/9
66.6 = F -32
F = 32+66.6 =
F = 98.6
Thus, the temperature of 310 K in Fahrenheit is 98.6F.

Answer:
3.53 m/s towards the left
Explanation:
= Mass of first glider = 400.5 g
= Mass of Second glider = 500 g
= Initial Velocity of first object = 2.3 m/s
= Initial Velocity of second object = -2.95 m/s
As momentum and Energy is conserved


From the two equations we get

The velocity of first glider after collision is 3.53 m/s towards the left
