___________ is a tiny, hair-like fiber that aids in movement.

A parallel-plate capacitor in air has circular plates of radius 2.8 cm separated by 1.1 mm. Charge is flowing onto the upper pla

Hatshy [7]

Answer:

The time rate of change of the electric field between the plates is $\frac{E }{t} = 2.29 *10^{14} \ N \cdot C \cdot s^{-1}$

Explanation:

From the question we are told that

The radius is $r = 2.8 \ cm = 0.028 \ m$

The distance of separation is $d = 1.1 \ mm = 0.0011 \ m$

The current is $I = 5 \ A$

Generally the electric field generated is mathematically represented as

$E = \frac{q }{ \pi * r^2 \epsilon_o }$

Where $\epsilon_o$ is the permitivity of free space with a value

$\epsilon_o = 8.85*10^{-12 }\ m^{-3} \cdot kg^{-1}\cdot s^4 \cdot A^2$

So the time rate of change of the electric field between the plates is mathematically represented as

$\frac{E }{t} = \frac{q}{t} * \frac{1 }{ \pi * r^2 \epsilon_o }$

But $\frac{q}{t } = I$

So

$\frac{E }{t} = * \frac{I }{ \pi * r^2 \epsilon_o }$

substituting values

$\frac{E }{t} = * \frac{5 }{3.142 * (0.028)^2 * 8.85 *10^{-12} }$

$\frac{E }{t} = 2.29 *10^{14} \ N \cdot C \cdot s^{-1}$

State guy lussac law

tatuchka [14]

The combined gas law has no official founder; it is simply the incorporation of the three laws that was discovered. The combined gas law is a gas law that combines Gay-Lussac’s Law, Boyle’s Law and Charle’s Law. Boyle’s law states that pressure is inversely proportional with volume at constant temperature. Charle’s law states that volume is directly proportional with temperature at constant pressure. And Gay-Lussac’s law shows that pressure is directly proportional with temperature at constant volume. The combination of these laws known now as combined gas law gives the ratio between the product of pressure-volume and the temperature of the system is constant. Which gives PV/T=k(constant). When comparing a substance under different conditions, the combined gas law becomes P1V1/T1 = P2V2/T2.

If wavelength and speed of a wave are 4 m and 332 m/s respectively, calculate its frequency

Furkat [3]

Explanation:

Given 

wavelength = 4 m

speed = 332 m/s

frequency = ?

We know we have the formula 

wavelength = speed / frequency 

4 = 332 / frequency 

frequency = 332/4

Therefore frequency is 83 Hertz .

A net force of 0.7 N is applied on a body. What happens to the acceleration of the body in a second trial if half of the net for

Dmitriy789 [7]

Answer:

The answer is The acceleration is double its original value.

Explanation:

<h2>It is because of the second trial of accelaration. Because of this, an object's acceleration doubles from its original value.</h2><h2></h2>

Hope this helps....
