Answer:
The current in second wire is 5.0 A.
(B) is correct option.
Explanation:
Given that,
Current in first wire = 3.7 A
Distance = 8.0 cm
We need to calculate the magnetic field due to the current carrying wire
Using formula of magnetic field
Where, I = current
r = distance
Put the value into the formula
For first wire
...(I)
For second wire,
The distance is 8-3.7 = 4.3 cm
...(II)
The magnetic field in both the wires,
From equation (I) and (II)
Hence, The current in second wire is 5.0 A.
ANSWER: A ramp meter, usually is a basic traffic light or a two-section signal light, together with a signal controller, that regulates the flow of traffic that enters freeways according to the most traffic conditions.
K.E= 50,000 Joules= 1/2mv^2=1/2x1,000kgxv^2
v^2=2x50,000 Joules/1,000kg = 100m^2/v62
v=10m/s
The speed of the car is 10 m/s
Answer: displacement
Explanation:
According to the definition of displacement it is the shortest distance between two points.
