Answer:
0.4344A
Explanation:
From Ampere's law, it can be shown that the magnetic field B inside a long solenoid is
Where
B= Magnetic field strenght at distance d
I= current
Permeability of free space (
)
N= Number of loops
Our values are defined as follow,
T
As a current required to become 104 times the Earth's magnetic field is required, we use B '
<em>Therefore is needed 0.4344A in the solenoid to produce a magnetic field inside the solenoid, near its center, that is 104 times the Earth's magnetic field.</em>
Answer:
F' = F/12
Therefore, the electrostatic force is reduced to one-twelve of its original value.
Explanation:
The electrostatic force of attraction or repulsion between to charges is given by Coulomb's Law:
F = kq₁q₂/r² ---------- equation 1
where,
F = Electrostatic Force
k = Coulomb's Constant
q₁ = magnitude of first charge
q₂ = magnitude of 2nd charge
r = distance between charges
Now, if we double the distance between charges and reduce one charge to one-third value, then the force will become:
F' = kq₁'q₂'/r'²
where,
q₁' = (1/3)q₁
q₂' = q₂
r' = 2r
Therefore,
F' = k(1/3 q₁)(q₂)/(2r)²
F' = (1/12)kq₁q₂/r²
using equation 1:
<u>F' = F/12</u>
<u>Therefore, the electrostatic force is reduced to one-twelve of its original value.</u>
The average force a 70.0 kg sprinter exerts backward on the track is 84 N.

What is law of conservation of energy?</h3>
The law of conservation of energy states that energy can neither be created nor destroyed but can be converted from one form to another.
E = Fd
where;
- F is the applied force
- d is the displacement of the object
The average force exerted by the sprinter is calculated as follows;
F = ma
where;
- a is the acceleration of the sprinter
- m is mass of the sprinter
The acceleration of the sprinter is calculated as follows;
v² = u² + 2as
where;
- v is the final velocity
- u is the initial velocity
- s is the distance
(8)² = (2)² + (2x25)a
64 = 4 + 50a
60 = 50a
a = 60/50
a = 1.2 m/s²
Average force exerted by the sprinter;
F = ma
F = 70 kg x 1.2 m/s²
F = 84 N
