Physics
1 answer:
GenaCL600 [577]3 years ago
5 0

Answer:

72 volts.

Explanation:

To solve this, we have to use the Ohm's law.

The ohm's law tells us that the voltage drop of a resistor is directly proportional to the current applied to the conductor.

V=I*R

in this case the current is 1.8 amps and the resistor is 40 ohm

V=1.8*40

so

V=72 volts.

How can you say that joule and Newton are derived units​
maxonik [38]

Answer:

F = M a    where M is acceleration and a is acceleration

a = x / s^2 = distance / time squared

The Newton is derived because mass, distance, and time are all fundamental units One would have to look at the fundamental requirements for these definitions, but they can all be repeated in a laboratory.

So the Newton is determined from these fundamental units and since the Joule equals Newton * Distance it is also derived from the fundamental units.

If one has the three fundamental units then one can derive the Joule and Newton.
