The sample's density with respect to the volume it displaces is equal to: C. 0. 60 g/mL
<u>Given the following data:</u>
- Mass = 1.8 grams
- Initial volume = 20 mL
- Final volume = 23 mL
To calculate the sample's density:
First of all, we would determine the volume displaced by the sample;
Volume displaced = 3 mL
Density can be defined as mass all over the volume of an object. Thus, density is mass per unit volume of an object.
Mathematically, the density of a substance is given by the formula;
Substituting the given parameters into the formula, we have;
Density = 0.60 g/mL

(a)
The tangential acceleration component of the car is simply equal to the change of the tangential speed divided by the time taken:
This rate of change is already given by the problem, 0.800 m/s^2, so the tangential acceleration of the car is
(b)
The centripetal acceleration component is given by
where
v is the tangential speed
r is the radius of the trajectory
When the speed is v = 3.00 m/s, the centripetal acceleration is (the radius is r = 10.0 m):
(c)
The centripetal acceleration and the tangential acceleration are perpendicular to each other, so the magnitude of the total acceleration can be found by using Pythagorean's theorem:
and the direction is given by:
where the angle is measured with respect to the direction of the tangential acceleration.
