Explanation:
It is given that,
Length of the copper wire, l = 4.4 m
Diameter of copper wire, d = 1.3 mm = 0.0013 m
Radius of copper wire, r = 0.00065 m
The resistivity of the copper wire,
We need to find the resistance of the copper wire. It is given by :
R =0.055 ohms
So, the resistance of the copper wire is 0.055 ohms. Hence, this is the required solution.
The acceleration of the object if the net force is decreased = 0.13 m/s²
<h3>Further explanation</h3>Given
A net force of 0.8 N acting on a 1.5-kg mass.
The net force is decreased to 0.2 N
Required
The acceleration of the object if the net force is decreased
Solution
Newton's 2nd law :
The mass used in state 1 and 2 remains the same, at 1.5 kg
- state 1
ΣF=0.8 N
m=1.5 kg
The acceleration, a:
- state 2
ΣF=0.2 N
m=1.5 kg
The acceleration, a:
