None of the diagrams you attached shows the scenario accurately,
or at all.
Heat flows from Object-B to Object-A, until both objects are at
the same temperature, somewhere between 10°C and 29°C.
The electromotive force on the free electrons in the wire is given by
E=vBl
where v is the velocity, B is the field component perpendicular to the wire and l is the length of the wire. So we get
E=15.6*40E-6*2.5m=1.56mV
Now the force that causes this to happen is given by F=q(v X B) where q is the charge on the electron which is negative. the cross product of the velocity and magnetic field points in a direction that is westward. Since the electrons are negative they are pushed to the east, leaving the west end of the wire with a positive charge .
Explanation:
Eg = mgh
a. Eg = (2.00 kg) (9.8 m/s²) (12.0 m)
Eg = 235 J
b. Eg = (2.00 kg) (9.8 m/s²) (3.00 m)
Eg = 58.8 J
c. Eg = (2.00 kg) (9.8 m/s²) (4.50 m)
Eg = 88.2 J
d. When the coconut hits the bystander:
Ek = 235 J − 58.8 J = 176 J
When the coconut hits the ground:
Ek = 88.2 J − 0 J = 88.2 J
Ek is the greatest when the coconut hits the bystander.
Answer : I = 0.0906 A.
Explanation :
It is given that,
No of electrons flowing in a wire,
We know that the charge on an electron is given by,
So the total charge becomes:
We know that the current in wire is defined as,
Hence, this is the required solution.
The final momentum of the ball is 3.8 kgm/s.
<h3>Change in momentum of the ball</h3>
The impulse received by the ball is equal to change in momentum of the ball.
J = ΔP
where;
- J is the impulse
- ΔP is change in momentum
ΔP = P₂ - P₁
P₂ = ΔP + P₁
<h3>Final momentum of the ball</h3>
The final momentum of the ball is calculated as follows;
P₂ = 8 + (- 0.1 x 42)
P₂ = 8 - 4.2
P₂ = 3.8 kgm/s
