Question

Convert the following to SI units without changing its values

a. 4000 g
b. 2.4 km

A. a. 4 kg, b. 2400 m
B. a. 4 kg, b. 2.4 x 10^3 m
C. a. 40 kg, b. 2400 m
D. a. 40 kg, b. 2.4 x 10^3 m

Answer 1

To convert 4000 g to kg, divide by 1000 to get 4 kg. To convert 2.4 km to meters, multiply by 1000 to get 2400 m. The correct SI units without changing the values are 4 kg and 2400 m.

Step-by-step explanation:

The question involves converting measurements into different SI units. The units given are '4000 g' and '2.4 km'. In SI units, mass is represented in kilogram (kg) and length in meter (m).

For part a, 4000 g can be converted to kilograms by dividing by 1000, since there are 1000 grams in a kilogram. This gives us:

• 4000 g / 1000 = 4 kg

For part b, 2.4 km is already in a unit of length, but we can convert kilometers into meters. There are 1000 meters in a kilometer, so:

• 2.4 km × 1000 = 2400 m

Therefore, the correct answer, maintaining each value, is:

a. 4 kg, b. 2400 m, which corresponds to option B.
