Answer:
Explanation:
Torque on a loop in a magnetic field
Maximum torque = M B
M is magnetic moment of loop and B is magnetic field
M = area x current
= 3.14 x .10² x i
Maximum torque = M B
1 x 10⁻³ = 3.14 x .10² x i x .65 x 10⁻⁴
i = 490 A
Current = 490 A.
I think it’s the cardiovascular system
Answer:
1. D
2. D
3. A
The reason why your body goes right and the car car goes left is because your body tries to stay where it was, which is on the right. Your upper body doesn't feel a force and because of that continues in the same direction. Your lower half is pulled out from under you by seat friction to the left, leaving you leaning to the right.
Answer:
E = 10t^2e^-10t Joules
Explanation:
Given that the current through a 0.2-H inductor is i(t) = 10te–5t A.
The energy E stored in the inductor can be expressed as
E = 1/2Ll^2
Substitutes the inductor L and the current I into the formula
E = 1/2 × 0.2 × ( 10te^-5t )^2
E = 0.1 × 100t^2e^-10t
E = 10t^2e^-10t Joules
Therefore, the energy stored in the inductor is 10t^2e^-10t Joules
They will rise to the 2nd layer of the atmosphere where the temperature decreases by a lot and then they will blow up
