There is not a time when the terminal voltage would exceed the emf. option A
<h3>What is the terminal voltage?</h3>
The terminal voltage is the voltage across the external circuit. We know that the emf is the voltage when current is not being delivered to the external circuit.
Now, we know that as current continue to be supplied to the external circuit the emf continues to drop. But it should be now that there is not a time when the terminal voltage would exceed the emf.

Answer:
tension is 37.8 N
Explanation:
given data
mass of bar m1 = 2 kg
length of bar L = 1.4 m
suspended mass m2 = 5 kg
suspended object position length L2 = 0.8 m
to find out
tension
solution
we consider here bar is connected with hinge and
we know here system is equilibrium
so here net torque will be zero at joint
and mass 2 kg act at L1 = 1.4 /2 = 0.7 m
so torque = m1×g× ( L1 ) + m2 ×g× (L2) - T(L)
so
2 ×9.8 × ( 1.4/2) + 5×9.8 × ( 0.8) - T(1.4) = 0
T = 52.98 / 1.4
T = 37.8
so tension is 37.8 N
