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:
Substitute these values into equation 1
Hence, the volume of the sample is 48.39 cm³.

Explanation:
O + 6V = 9V, so O = 3V
P = 9V as it is parallel to the 9V power supply.
The voltage in the extension cord is 30 V.
The problem above can be solved using ohm's law
⇒ Formula:
V = IR.................. Equation 1
⇒ Where:
- V = Voltage in the extension cord
- I = Current flowing through the extension cord
- R = Resistance of the extension cord.
From the question, I think there was a slight error in the value of the current given it suppose to be 500 A, and not 5.00 A
⇒ Given:
⇒ Substitute these values into equation 1
Hence the voltage in the extension cord is 30 V

Answer:
The trip with less acceleration has it when the radius is smaller, for which Gertrude is right
Explanation:
We will propose the solution of this exercise, with the second law of / newton
F = m a
where the acceleration is centripetal, whose equation is
a = v² / r
where v is the linear speed of the chair and r is its radius from the turning point.
Acceleration depends on the two parameters: linear speed and radius, for which reason we must take them into account for an analysis.
angular and linear speeds are related
v = w r
therefore we see that the linear speed also changes with the radius, but the angular speed is constant for the entire apparatus; let's substitute to see which variable is more important
a = (w r)² / r
a = w² r
Since the angular velocity is constant, the relationship dependency is linear with the radius.
The trip with less acceleration has it when the radius is smaller, for which Gertrude is right
Bernice's problem is that it does not take into account that the acceleration depends on the two parameters linear speed and radius
