You can calculate the mass by multiplying the density with the volume. So if you know the volume and the mass. You can calculate the density by doing mass ÷ volume

<u>Answer:</u> Holly can calculate the density of the block for the given information.

<u>Explanation:</u>

For the given options:

  • <u>Option A:</u> Acceleration

Acceleration is defined as the rate of change of velocity with respect to time. S.I. unit of acceleration is m/s^2 The equation used to calculate acceleration is:

a=\frac{v}{t}

  • <u>Option b:</u> Density

Density of an object is defined as the ratio of its mass and volume. The chemical equation representing density of an object is:  

\text{Density of object}=\frac{\text{Mass of object}}{\text{Volume of object}}

  • <u>Option c:</u> Force

Force is defined as the push or pull on an object with some mass that causes change in its velocity.

It is also defined as the mass multiplied by the acceleration of the object.

Mathematically,

F=ma

  • <u>Option d:</u> Velocity

Velocity is defined as the rate of change of position with respect to time. The equation used to calculate velocity is:

v=\frac{d}{t}

Hence, Holly can calculate the density of the block for the given information.

To determine an athlete's body fat, she is weighed first in air and then again while she's completely underwater. it is found th
il63 [147K]

The difference in weight is due to the displacement of water (the buoyancy of water is acting on the athlete thus giving her smaller weight).<span>

The amount of weight displaced or the amount of buoyant force is: </span>

Fb = 690 N - 48 N

Fb = 642 N

From newtons law, F = m*g. Using this formula, we can calculate for the mass of water displaced:

m of water displaced = 642N / 9.8m/s^2

m of water displaced = 65.5 kg

Assuming a water density of 1 kg/L, and using the formula volume = mass/density:

V of water displaced = 65.5kg / 1kg/L = 65.5 L

The volume of water displaced is equal to the volume of athlete. Therefore:

V of athlete = 65.5 L

The mass of athlete can also be calculated using, F = m*g

m of athlete = 690 N/ 9.8m/s^2

m of athlete = 70.41 kg

 

Knowing the volume and mass of athlete, her average density is therefore:

average density = 70.41 kg / 65.5 L

<span>average density = 1.07 kg/L = 1.07 g/mL</span>
