Answer:
I_max= 1000 A
Explanation:
Expression of torque is given by
τ= BIA Sinθ
B= strength of magnetic field
I= current
A= Area
for maximum torque θ=90°⇒sin 90=1
Now for I_max= τ/BA
Let us take the average magnetic field of the earth as 50μT.
Area is calculated as
Substitute the values and calculate for maximum current
I_max= 1000 A
Answer:
A combination of longitudinal & transverse
Explanation:
That's false. Think about a stone or a baseball, during the first
several seconds after you tossed it straight up, before it reaches
its maximum height and starts to come down again.
There's no upward force on it during that time.
Also, after a roller coaster reaches the top of the FIRST hill, there's
no upward force on it for the whole rest of the ride, even though it
coasts up many more hills.
That way the 5 cm long vector represents 50 km/h
