Answer:
Cape Point lighthouse
Explanation:
The lighthouse is located South of Cape Town, at a point where boats turn to go around the tip of Africa.
The new lighthouse has the most powerful light of all the lighthouses in South Africa, with a power of 10 megacandelas. That's why it's being visible for up to 63 km around.
It's a very important lighthouse helping to conduct the traffic around dangerous waters where 2 oceans meet.
Explanation:
It is given that,
Current in wire 1, I₁ = 10 A
Current in wire 2, I₂ = 20 A
Distance between wires, d = 10 cm = 0.1 m
Force per unit length is given by :




So, the magnetic force acting per unit length of the wires
. Since, the current is in same direction. So, the force is attractive in nature.
Answer:
84.196%
Explanation:
g = Acceleration due to gravity = 9.81 m/s²
x = 10 m
t = Time taken
= 3.5 m/s (assumed, as it is not given)
= 
We have the equation


From continuity equation we have

Fraction is given by

The fraction is 84.196%

Answer:
59.4 N
Explanation:
The force exerted on a current-carrying wire due to a magnetic field perpendicular to the wire is given by

where
I is the current in the wire
L is the length of the wire
B is the strength of the magnetic field
Here in this problem, we model the strike as a current-carrying wire, so we have:
I = 49,500 A is the current
L = 1 m is the length (we want to find the force per each meter of length)
is the strength of the magnetic field
Therefore, the force on each meter of the current due to the magnetic field is:
