i worked it out on a diffrent sheet so its hard to explain
The x and y-components of the vector R is 44.15i + 23.47j.
The given parameters:
- Magnitude of vector R = 50 m
- Position of vector R = 28 degrees
<h3>What is component vectors?</h3>
- This is the representation of vectors in x and y-coordinates.
The x and y-components of the vector R is calculated as follows;

R is a unit vector.

Just took it and got it right!</span>
The correct answer is: acceleration.
In fact, the slope of the graph of velocity versus time corresponds to the ratio between the variation of v and the variation of t:

But this is exactly the definition of acceleration:

, so acceleration is the correct answer.
Answer:
R = 0.93 ohms
Explanation:
Let's start by calculating the resistance of the coil,
V = I ( R + r )
Make R the subject of the above equation.
Hence,
V = IR + Ir
V - Ir = IR
( V - Ir )/I = R
Given that V = 10V
r = 0.07ohms
I = 10A ( this is an assumption )
( 10 - 10×0.07 ) ÷ 10
R = 0.93 ohms
Note: r is the internal resistance, R is the resistance, I is the current and the emf is represented as V. Since current was supposed to be included in the question but it was not, hence it was assumed to be 10A . Meaning whatsoever value is given for current will be substituted into the equation. Thanks
