Answer:
Explanation:
Normal length of spring = 28.3 cm
stretched length of spring = 38.2 cm
length of extension = 38.2 - 28.3 = 9.9 cm
= 9.9 x 10⁻² m
force applied to stretch = .55 x 9.8 ( mg )
= 5.39 N
Force constant = force applied / extension
= 5.39 / 9.9 x 10⁻²
= .5444 x 10² N /m
= 54.44 N/m
Answer:
The radius is 
Explanation:
From the question we are told that
The current is 
The magnetic field is 
Generally the magnetic field produced by a current carrying conductor is mathematically represented as

=> 
Here
is the permeability of free space with value 
=> 
=> 
The average force is -212.4 N
Explanation:
We can solve this problem by using the impulse theorem, which states that the impulse exerted on the object (the product of the force exerted and the time) is equal to the change in momentum of the object:

where
F is the net force on the object
is the time
m is the mass
is the change in velocity
In this problem, we have:
m = 26.3 kg

Solving for F, we find

where the negative sign indicates that the direction of the force is opposite to the motion of the object.
