A toaster needs a 110-volt outlet because it doesn’t need
too much electricity. Electricity can be
converted to heat, and toaster only needs to be heated and nothing else that
requires extra electricity while clothes dyer requires higher voltage because
it needs more effort and electricity in order to do its function.
Answer:
Density = 1.14 kg/mm³
Explanation:
Given the following data;
Volume = 2.10 cm³ to mm = 2.10 * 10 = 21 mm³
Mass = 23.94kg
To find the density;
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;

Substituting into the equation, we have;

Density = 1.14 kg/mm³
Density is calculated as mass per unit volume. In this case, since the material has a mass of 47 grams and we have the volume of 15 cm^3, we can simply divide the values:
Density = 47 grams / 15 cm^3 = 3.1 g/cm^3
Therefore, the material has a density of 3.1 g/cm^3
