The intensity of the magnetic force exerted on the wire due to the presence of the magnetic field is given by

where
I is the current in the wire
L is the length of the wire
B is the magnetic field intensity

is the angle between the direction of the wire and the magnetic field
In our problem, L=65 cm=0.65 m, I=0.35 A and B=1.24 T. The force on the wire is F=0.26 N, therefore we can rearrange the equation to find the sine of the angle:

and so, the angle is
C. Observations and measurements
Answer:
<h2>6 s</h2>
Explanation:
The time taken by the cyclist can be found by using the formula

v is the velocity
d is the distance
From the question we have

We have the final answer as
<h3>6 s</h3>
Hope this helps you
Correct answer would be d
I changed my undershorts. The elastic on the old ones I put on that day was deteriorated, and it completely failed when I dripped lab coffee on it, causing falldown.
