A substance sample has a Mass of 45.0 g, and the Data Safety
marishachu [46]

The volume of the sample is 48.39 cm³.

<h3 /><h3>What is volume?</h3>

The term volume refers to the amount of three-dimensional space taken up by an item or a closed surface

To calculate the volume of the sample, we use the formula below

Formula:

  • D = m/v
  • v = m/D................ Equation 1

Where:

  • m = Mass of the smaple
  • D = Density of the sample
  • v = Volume of the sample.

From the question,

Given:

  • m = 45 g
  • D = 0.93 g/cm³

Substitute these values into equation 1

  • v = 45/0.93
  • v = 48.39 cm³

Hence, the volume of the sample is 48.39 cm³.

notsponge [240]

Answer:

 F = 0

Explanation:

Newton's second law is

         F = ma

As in this case the two blocks move with constant speed, it implies that the acceleration is zero, therefore the force applied to the system is zero

       F = 0
