Answer:
B. They usually need to be cooled to dissipate thermal energy build-up and prevent damage.
Explanation:
High energy mechanical devices needs to be cooled down because they have moving parts which creates heat which may affect the other electrical and electronic component of the device. Because quality of material changes with the temperature. If high temperature occur might change the shape of that component and may affect the efficiency of the machine.
I believe the correct answer from the choices listed above is option B.

Answer:
Mass = 27.6 grams
Explanation:
Given the following data;
Density of ice = 0.92g/cm³
Volume = 30cm³
To find mass of ice;
Density can be defined as mass all over the volume of an object.
Simply stated, density is mass per unit volume of an object.
Mathematically, density is given by the equation;
Making mass the subject of formula, we have;
Mass = 27.6 grams
Therefore, the mass of ice is 27.6 grams.
