Answer:
0.5 A
Explanation:
Applying,
V = IR.................. Equation 1
Where V = Voltage, I = current, R = Resistance.
make I the subject of the equation
I = V/R............... Equation 2
From the question,
Given: V = 75 V, R = 150 Ω
Substitute these values into equation 2
I = 75/150
I = 0.5 A.
Hence the cuurent through the resistor is 0.5 A
Answer:
(a) Friction force = 50 N
(b) Work done by friction = 300 j
(c) Net work done = 0 j
Explanation:
We have given that the box is pulled by 6 meter so d = 6 m
Force applied on the box F = 60 N
We have have given that velocity is constant so acceleration will be zero
So to applied force will be utilized in balancing the friction force
So friction force ![F_{friction}=50N](https://tex.z-dn.net/?f=F_%7Bfriction%7D%3D50N)
Work done by friction force ![W_{friction}=F_{friction}\times d=50\times 6=300j](https://tex.z-dn.net/?f=W_%7Bfriction%7D%3DF_%7Bfriction%7D%5Ctimes%20d%3D50%5Ctimes%206%3D300j)
Work done by applied force ![W=F\times d=50\times 6=300j](https://tex.z-dn.net/?f=W%3DF%5Ctimes%20d%3D50%5Ctimes%206%3D300j)
So net work done = 300-300 = 0 j
