Answer:

As voltage increases, current increases and resistance stays the same .

Explanation:

Ohm's law gives the relationship between the voltage, resistance, and current. The mathematical form of Ohm's law is given by :

$V\propto I\\\\V=IR$

R is resistance

I is current

V is voltage

So, as voltage increases, current increases and resistance stays the same. The correct option is (A).

Sunlight shines through a salt shaker. Should you expect more, less, or the same amount of scattering from blue light compared t

pshichka [43]

Blue light will scatter more compared to red light.

Blue light has a short wavelength; red light a longer wavelength. The sky looks blue because blue light is scattered far more than red light, owing to the shorter wavelength of blue light.

<h3>What is scattering of light?</h3>

Scattering of light is the phenomenon in which light rays deviate from their original path upon striking an obstacle like dust, gas molecules or water vapors. Scattering of light gives rise to many spectacular phenomena such as Tyndall effect and the red hues that can be seen at sunrise and sunset.

<h3>What is the scattering of light with example?</h3>

Some example of scattering of light that we come across in day-to-day life are: Blue colour of the sky: Out of the seven components present in sunlight, blue colour is scattered the most by the particles present in the atmosphere and hence, the sky appears blue.

B.A certain piece of copper wire is determined to have a mass of 2.00 g per meter.

masha68 [24]

Answer:

14cm

Explanation:

Mass per gram of the piece of wire;

2g of the wire is found in 1m

Since

100cm = 1m;

So;

100cm of the wire contains 2g of the wire

To provide 0.28g

Since;

2g of wire is made up of 100cm

0.28g of wire will be contained in $\frac{100 x 0.28}{2}$ = 14cm

14cm of the wire will contain 0.28g
