Which equation represents ohm's law?
Literally, ohm's law implies that current (I) is directly proportional to voltage (V) and inversely proportional to resistance (R).
Mathematically, this can be represented as:
![I\ \alpha\ \frac{V}{R}](https://tex.z-dn.net/?f=I%5C%20%5Calpha%5C%20%5Cfrac%7BV%7D%7BR%7D)
Convert the expression to an equation
![I\ =\ \frac{V}{R}](https://tex.z-dn.net/?f=I%5C%20%3D%5C%20%5Cfrac%7BV%7D%7BR%7D)
Multiply both sides by R to make V the subject
![I\ * R\ =\ \frac{V}{R} * R](https://tex.z-dn.net/?f=I%5C%20%2A%20R%5C%20%3D%5C%20%5Cfrac%7BV%7D%7BR%7D%20%2A%20R)
![I\ * R\ =V](https://tex.z-dn.net/?f=I%5C%20%2A%20R%5C%20%3DV)
Reorder
![V = I\ * R](https://tex.z-dn.net/?f=V%20%3D%20I%5C%20%2A%20R)
![V = IR](https://tex.z-dn.net/?f=V%20%3D%20IR)
<em>Option (a) is correct; Others are not</em>
Answer:
Angular acceleration = 23.68 rad / s²
Explanation:
Given that,
acceleration = 9m/s²
Therefore acceleration of string is 9m/s²
since string is constant in length
cylinder of radius 38.0 cm = 0.38m
Angular acceleration = a / r
Angular acceleration = 9 / 0.38
= 23.68 rad / s²
Angular acceleration = 23.68 rad / s²
<h3>Question -:</h3>
The Earth orbits around the sun because the gravitational force that the sun
exerts on the Earth:
O A. causes Earth's acceleration toward the sun.
O B. is very small because the sun is so far from the Earth.
O c. is smaller than the force the Earth exerts on the sun.
O D. pushes the Earth away from the sun.
<h3>Answer -:</h3>
O A. causes Earth's acceleration toward the sun.
