Make a conclusion on the relationship of mass to the rate of the change of motion of the balloon at a constant force.

sasho [114]

At a constant force, the mass of the balloon is inversely proportional to the rate of change motion of the balloon.

The force applied to an object can be determined by applying Newton's second law of motion, the force applied to an object is directly proportional to the product of mass and acceleration of the object.

F = ma

$F = m\frac{\Delta v}{t} \\\\\frac{F}{\frac{\Delta v}{t} } = m$

The mass of an object is inversely proportional to the rate of change motion of the object.

Thus, we can conclude that at constant force, the mass of the balloon is inversely proportional to the rate of change motion of the balloon.

A parallel plate capacitor is constructed with a dielectric slab with κ = 1.5 inserted between the plates. The area of each plat

maksim [4K]

Answer:

The value is $V = 4.533 \ V$

Explanation:

From the question we are told that

The dielectric constant is k = 1.5

The area of each plate is $A = 5 \ cm^2 = 0.0005 m^2$

The distance between the plates is $d= 1 \ mm = 0.001 \ m$

The charge on the capacitor is $Q = 6*10^{-11} \ C$

Generally the electric field in a vacuum is mathematically represented as

$E_o = \frac{V_o}{d}$

Generally $V_o$ is the voltage of the capacitor which is mathematically represented as

$V_o = \frac{Q}{C_o}$

Here $C_o$ is the capacitance of the capacitor in a vacuum which is mathematically represented as

$C_o = \frac{\epsilon_o * A}{d}$

Here $epsilon_o$ is a constant with value $epsilon_o= 8.85*10^{-12} C^2 \cdot N^{-1} \cdot m^{-2}$

=> $C_o = \frac{8.85*10^{-12} * 0.0005 }{0.001}$

=> $C_o = 4.425 *10^{-12} \ F$

$V_o = \frac{6*10^{-11} }{ 4.425 *10^{-12}}$

$V_o = 13.6 \ V$

$E_o = \frac{ 13.6}{0.001}$

=> $E_o = 13600 \ V/m$

The electric field when the dielectric slab is inserted is mathematically represented as

$E = \frac{E_o}{k}$

=> $E = \frac{13600}{1.5}$

=> $E =9067 \ V/m$

Generally the electric field between the plates is mathematically evaluated as

$E_{N} = E_o - E$

=> $E_{N} = 13600- 9067$

=> $E_{N} = 4533 \ V/m$

Generally the potential difference between the plates is

$V = 4533 * 0.001$

=> $V = 4.533 \ V$

Why is it important to cite units when engaging in scientific conversation / problem solving?

Dmitriy789 [7]

It is really important to cite units while engaging with scientific problems as they help in evaluating the right solution without any mistake.

<u>Explanation: </u>

While solving analytical questions to evaluate the right answers, the units play a crucial role in the equations. With the help of units in the formula, we can easily judge whether we are placing the values in the same parameters and hence, lessen the probabilities of wrong answers.

For example, while adding two measurements i.e. 4 m and 36 cm; if we don't consider the units and move on with the addition, the answer will be 40. Now, the first thing is that we are adding two measurements of different parameters. Besides this, the answers will be wrong i.e. 4.36 m is the correct answer instead of 40 and that too without mentioning the unit.

The chances of selecting the wrong answer are more when we need to choose options out of multiple choices because here we often get confused. That's why we should always make sure that we approach the scientific questions along with the units.
