Answer:

Explanation:

The first method to engage is to listen to where the sound of air in the inner Tor escaping originated and look to see if u can find it. You can then feel the escape air with your hand.

You can Put it inside a container of water and see the bubble and rotate the inner tube to pass all of it through the water

Find electric field at point p which is a distance l away from the both +q and -q

denis-greek [22]

Answer:

$\frac{1}{4\times(pie)\times\text{E}} \times\frac{q}{I^{2} }+\frac{1}{4\times(pie)\times\text{E}} \times\frac{-q}{I^{2} }$

Explanation:

As given point p is equidistant from both the charges

It must be in the middle of both the charges

Assuming all 3 points lie on the same line

Electric Field due a charge q at a point ,distance r away

$=\frac{1}{4\times(pie)\times\text{E}} \times\frac{q}{r^{2} }$

Where

q is the charge
r is the distance
$E$ is the permittivity of medium

Let electric field due to charge q be F1 and -q be F2

I is the distance of P from q and also from charge -q

⇒

F1 $=\frac{1}{4\times(pie)\times\text{E}} \times\frac{q}{I^{2} }$

F2 $=\frac{1}{4\times(pie)\times\text{E}} \times\frac{-q}{I^{2} }$

⇒

F1+F2= $\frac{1}{4\times(pie)\times\text{E}} \times\frac{q}{I^{2} }+\frac{1}{4\times(pie)\times\text{E}} \times\frac{-q}{I^{2} }$

A droplet of pure mercury has a density of 13.6 g/cm3. What is the density of a sample of pure mercury that is 10 times as large

luda_lava [24]

A droplet of pure mercury has a density of 13.6 g/cm3. What is the density of a sample of pure mercury that is 10 times as large as the droplet?

Answer: In this case the density will remain constant for both droplets. The reason being that volume will not change the density of the material. The only way of changing it is by changing its state. If you increase the volume then the mass will also increase. Leaving the density the same.

I hope it helps, Regards.

5) A parallel series electric blasting circuit consists of 6 branches of 8 caps each. Cap legwire length is 28 ft. The cap circu

andrezito [222]

Answer:

Minimum DC current $= 9$ Ampere

Voltage $= 74.862$ V

Explanation:

Here in this questions three resistors are used in series

Resistance of cap circuit

$R_1 =\frac{ 8* 2.3}{6} \\R_1 = 3.067$

Here $2.3$ is the resistance per cap

Resistance of bus wire

$R_2 = \frac{50 * 4.02 }{1000} \\R_2 = 0.201$

Where $4.02$ is the resistance per $1000$ feet of bus wire of gauge 16

Resistance of firing line

$R_3 = \frac{(2*1000)* 2.525}{1000} \\R_3 = 5.05$

where $2.525$ is the resistance per $1000$ feet of bus wire of gauge 14

Total resistance is equal to

$R = R_1 + R_2 + R_3\\R = 3.067 + 0.201 + 5.05 \\R = 8.318$

Current in firing line is equal to

$1.5 * 6\\= 9$

Voltage is equal to product of resistance and current

$= 9 * 8.318\\= 74.862$
