Answer:
I = 12*B (the information about B does not appear in the statement)
Explanation:
The motion of the segment of the circuit, in a constant magnetic field makes that opposite charges inside the segment separate of each other. This generate a induced potential difference at the ends of the segment that is given by the following formula:
(1)
v: speed of the segment = 2.0m/s
B: magnitude of the magnetic field
(2)
The induced current calculated by replacing the result of (2) in the following formula:
(3)
Then, you only have to replace the value of the magnitude of the magnetic field B in (3) to calculate the current.
Answer:
200N
Explanation:
Given parameters:
Mass of wagon = 100kg
Acceleration = 2m/s²
Unknown:
Force on the wagon = ?
Solution:
From Newton's second law of motion:
Force = mass x acceleration
Now insert the parameters and solve;
Force = 100 x 2 = 200N
