Answer:

I = 0.058 [A]

Explanation:

Ohm's law is defined as voltage equal to the product of current by resistance.

V =I*R

where:

V = voltage = 4.2 [V]

I = current [amp]

R = resistivity = 72 [ohm]

Now clearing I, we have:

I = V/R\\I = 4.2/72\\I = 0.058 [A]

Answer: B

Explanation:the voltage is just like the force that drives the current through out the circui... When trippled, the force increases and the current increases since the resistance in the circuit remains constant.

If an object is conductive what do you know it can do?
fredd [130]

Explanation:

some objects that are conduct :Metals conduct electricity, so if there is just the symbol of a metal, eg Mg(s), then it will conduct, even in the solid or liquid state. 2. Ionic compounds conduct when they are dissolved in water, or are melted.

what can it do ?:

A conductor is a material which electricity, heat or sound can flow through. An electrical conductor conducts electricity. ... This means that they make it very hard for electricity to flow through them. A material that stops electric current is called an insulator (electricity).

hope this helped! if not I'll answer again

How would the photographer use the polarizing filter to find out the direction of polarization of the light coming from the blue
aleksklad [387]

Answer:

by rotating the filter                    

Explanation:

Rayleigh's scattering is given by the process of the scattering of light by molecules. This is very important physical phenomenon. Polarization is also an effect of light scattering.

A photographer wishes to capture photos of some cloud formation by using the polarizing filter. So the photographer will have to rotate the polarizing filter until the intensity of the light becomes maximum such that the light polarization is acts along the axis of the filter.
