The AU ... Astronomical Unit ... used to be defined as the average distance between the Sun and Earth during the year.
Now it's defined as 149,597,870,700 meters exactly.
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.

I believe that is a Geiger Counter
Answer:
d = 186.3 m
Explanation:
Given that,
Speed of Matthew 3.45 m/s due eastward
It takes 54 seconds to walk to the store.
We need to find the distance covered. The product of speed and time is equal to the distance covered.
d = vt
Putting all values,
d = 3.45 m/s × 54 s
d = 186.3 m
Hence, he will cover a distance of 186.3 m.
