Multiplication is commutative. So both

V=IR and V=RI is same and correct formula of Ohm's law.

Setler [38]3 years ago

Answer:

V = I R

Explanation:

As per ohm's law the voltage difference across a given resistor is the product of current and resistance of the resistor

So we will have

V = I R

here we know that

I = electric current in the given resistor

R = resistance of the given resistor

V = voltage difference across the resistor

The scientific question can be supported by evidence that must be true of the possible answers to a scientific question. Option D is correct,

<h3>What is a Scientific hypothesis?</h3>

A scientific hypothesis must meet two criteria, A scientific hypothesis must be testable, and a scientific hypothesis must be falsifiable The basic idea of a hypothesis is that there is no predetermined outcome.

For a solution to be termed a scientific hypothesis, it has to be an idea that can be supported or refuted through carefully crafted experimentation or observation.

Only scientific questions may be answered by scientific activity. The design of the research is also influenced by scientific issues.

The scientific question can be supported by evidence that must be true of the possible answers to a scientific question.

They are accurate regarding the scientific question and can be substantiated by proof.

​

Hence option D is correct.

How much gravitational potential energy does an object have if it is located 20 m above the point that we define as O height and
raketka [301]

Answer:

Explanation:

PE = mgh where m is the mass in kg, g is the pull of gravity which is 9.8, and h is the height of the object above the point to which it could possibly fall, measured in meters. Plugging in:

PE = 10(9.8)(20) so

PE = 1960 J

This should be rounded to 1 sig fig according to the rules of sig fig and your numbers here, but I imagine you're not following them all that much. It should be 2000 J
