Answer: What are the answer options?
Explanation:
Answer:
option B
Explanation:
given,
spring constant (k ) = 45 N/m
distance of the spring = 0.8 m
Magnitude of the force to handle grip = ?
Magnitude of spring force =
F = k x
F = 45 x 0.8
F = 36 N
The magnitude of spring force is equal to F = 36 N
The correct answer is option B
B) 37 V
The potential difference between point a and point b is equal to 37 V
<h3>
Explanation:</h3>
The potential difference across a and b can be calculated by finding the equivalent resistance of the resistors R1, R2 and R3 and then by applying Ohm's law.
Given:
R1 = 3.0 Ω
R2 = 8.0 Ω
R3 = 10.0
Current = I = 5 A
<u>To calculate equivalent resistance of the circuit: </u>
R2 and R3 are connected in parallel configuration. The equivalent resistance of R2 and R3 can be calculated as
Resistance R1 is in series with Rp. The equivalent series resistance is calculated as
Thus the given 3 resistor circuit can be written as an equivalent resistance Rs equal to 7.44 Ω through which current I passes.
By Ohm's law;
If V is the potential difference between a and b
Potential difference across points a and b = Current flowing through the circuit × Resistance between points a and b
37.2 V ≈ 37 V
Therefore, the potential difference between point a and point b is equal to 37 V
