In a certain material there is a current of 16 A flowing through a surface to the right, and there is an equal amount of positiv

e and negative charge passing through the surface producing the current. How much negative charge passes through the surface?

Answer:

Explanation:

Give that

I=16A

The current is flowing to the right

Equal amount of positive and negative charges.

i.e, total charge is q= Q+Q=2Q. i.e magnitude

Then, the rate of charge that pass though is dq/dt

Give that,

q=it

2Q=it

Let differentiate with respect to t

2dQ/dt=i

Then, dQ/dt=i/2

Since i=16A

Then, dQ/dt=16/2

dQ/dt= 8 A/s. Toward the left

Describe how an iron tyre is fitted onto the wheel of a train. ​
Novay_Z [31]

Explanation:

The tyre is a hoop of steel that is fitted around the steel wheel centre and a groove on inside diameter of a flange face. The diameter inside is machined to be slightly less than the wheel diameter at the centre on which it is mounted to give an interference fit.

A 243 mL cup of whole milk contains about 45 mg of cholesterol. Express the cholesterol concentration of the milk in kilograms p
timama [110]

Answer: 0.1851 \frac{kg}{m^{3}}

Explanation:

We have this concentration in units of mg/ml:

\frac{45 mg}{243 ml}

And we need to express it in kg/m^{3}, knowing:

1 ml= 1 cm^{3}

1 m^{3}= (100 cm) ^{3}

1g = 1000 mg

1 kg = 1000 g

Hence:

\frac{45 mg}{243 cm^{3}} \frac{1 g}{1000 mg} \frac{1 kg}{1000 g} \frac{(100 cm) ^{3}}{1 m^{3}}=0.1851 \frac{kg}{m^{3}}

A small laser used as a pointer produces a beam of red light 5 mm in diameter, and has a power output of 5 milliwatts. What is t
Nata [24]

Answer:

434.0 V/m

Explanation:

The power output of the laser is:

P=5 mW = 0.005 W

while the radius of the beam is

r=\frac{5 mm}{2}=2.5 mm = 0.0025 m

so the cross-sectional area is

A=\pi r^2 = \pi (0.0025 m)^2=2.0\cdot 10^{-5} m^2

So the intensity of the laser beam is

I=\frac{P}{A}=\frac{0.005 W}{2.0\cdot 10^{-5} m^2}=250 W/m^2

The intensity of a laser beam is related to the magnitude of the electric field by

I=\frac{1}{2}c\epsilon_0 E^2

where

c is the speed of light

\epsilon_0 is the vacuum permittivity

Solving the formula for E, we find

E=\sqrt{\frac{2I}{c\epsilon_0}}=\sqrt{\frac{2(250 W/m^2)}{(3\cdot 10^8 m/s)(8.85\cdot 10^{-12} F/m)}}=434.0 V/m
