Explanation:
From the question we are told that
The temperature coefficient is
The resistance of the filament is mathematically represented as
Where is the initial resistance
Making the change in temperature the subject of the formula
Now from ohm law
This implies that current varies inversely with current so
Substituting this we have
From the question we are told that
Substituting this we have
=>
Answer:
v = 88.89 [m/s]
Explanation:
To solve this problem we must use the principle of conservation of momentum which tells us that the initial momentum of a body plus the momentum added to that body will be equal to the final momentum of the body.
We must make up the following equation:
where:
F = force applied = 4000 [N]
t = time = 0.001 [s]
m = mass = 0.045 [kg]
v = velocity [m/s]
