Question

If the length of the axle was cut 5mm shorter, the volume would be reduced to 0.281 cm^3. What would be the new mass of the axle?

a) Not enough information to determine
b) Same as the original mass
c) Decreased by a specific amount
d) Increased by a specific amount

Answer 1

Without the material density or original volume of the axle, you cannot determine the new mass after cutting the length by 5mm, resulting in a volume reduction to 0.281 cm^3.

Step-by-step explanation:

The question is asking for the new mass of an axle if its length was cut 5mm shorter, given a reduction in volume to 0.281 cm^3. Unfortunately, without the information about the material of the axle which determines the density, or original volume to work out the original mass, you cannot calculate the new mass directly. The options provided suggest qualitative outcomes such as a decrease or increase, but for specificity, the exact material properties are needed.

b) The volume of the cylinder must be calculated using the formula V = πr^2h. However, in this scenario, since we don't have enough information to calculate the change in mass that would result from the reduced volume, the answer to the question is (a) Not enough information to determine.
