Question

Five thousand volts can be expressed as

(a) 5000 V
(b) 5 MV
(c) 5 kV
(d) either (a) or (c)

Answer 1

Five thousand volts can be expressed as 5000 V or 5 kV, corresponding to options (a) and (c) respectively.

Step-by-step explanation:

The question is asking how to express five thousand volts. In the International System of Units (SI), the prefix 'kilo-' (k) stands for thousands, so one thousand volts is 1 kV. Therefore, five thousand volts can be correctly expressed as 5 kV (option c). It can also be simply presented without a prefix as 5000 V (option a). Because 'mega-' (M) represents millions, 5 MV would be incorrect for five thousand volts. Therefore, the correct answers are (a) 5000 V and (c) 5 kV.
