A 12.0 volt battery is connected in a series to 4 identical 5.00 ohm resistors connected in parallel to each other. What is the current through the battery?

Answers

Answer:

9.6 Amperes

Explanation:

since the resistors are connected in parallel connection the equivalent resistance is

1/R = 1 /5 + 1/5 + 1/5 + 1/5

solving for R we get 5/4 ohms

then from V=IR

I = V/R

I=12/(5/4)

hence I= 9.6 Amperes

A 12.0-volt battery is connected in a series, then the current through the battery is 9.6 A.

What are Resistors?

Electrical resistance is implemented as a circuit element by resistors, which are passive two-terminal electrical components. Resistors are devices that are used in electronic circuits for a variety of purposes, including lowering current flow, adjusting signal levels, dividing voltages, biasing active components, and terminating transmission lines.

As part of motor controllers, power distribution systems, or as test loads for generators, high-power resistors that can dissipate many watts of electrical energy as heat may be used.

According to the question,

1/R = 1 /5 + 1/5 + 1/5 + 1/5

R = 5/4 ohms

By ohm's law,

V=IR

I = V/R

I=12/(5/4)

I= 9.6 Amperes

I have always wondered if the saying it was hot enough to fry an egg on the sidewalk could 20 points be true. Please describe how you would determine if this could really happen.

Answer:

This is one of the hottest summers America has ever seen and Jeremiah Warren is taking advantage of the heat wave and doing a little cooking…in his car!

It was about 98 or 99 degrees in Texas, so Jeremiah thought he’d head outside to see if it was hot enough to actually cook food.  He buttered up a frying pan on his dashboard and filled it with an egg, cookie dough, a hot dog and bacon (mmm…bacon!).  He set up another frying pan on the sidewalk and a few hours later he came back for a mid-day snack.

The wavelength of a water wave is 6 cm when the frequency is 10 hertz .

1. What is the distance between successive crests of the wave ?
2. What is the speed of propagation ?
3 What is the period of the wave ?

Please show workings.​

Answers

The distance between successive crests (or successive troughs) is defined as the wavelength. The time elapsed between the crossings of two successive crests through a given point is the period of the wave.The Velocity of propagation (Vp) of a cable is the speed at which an electrical signal can propagate through the cable in comparison to the speed of light. For example, in a vacuum, the velocity of propagation would be 100% or 1 (depending on how it is represented).The wave period is the time it takes to complete one cycle. The standard unit of a wave period is in seconds, and it is inversely proportional to the frequency of a wave, which is the number of cycles of waves that occur in one second.

The cell membrane is capable of transforming oxygen and glucose into energy for the cell The cell membrane controls the movement of molecules into and out of the cell.

Answers

Answer:

The cell membrane is capable of transforming oxygen and glucose into energy for the cell

Explanation:

The cell membrane encapsulates all the organelles of the cell. It provides protection for the organelles of the cell.

It transports nutrients into the cell and toxic materials out of the cell. It also prevents the entry of harmful materials into the cell.

The cell membrane does not perform the function of  transforming oxygen and glucose into energy for the cell.

a 200 L of water tank is filled from a reason the inlet pipe at the bottom electrical overflow pipe prices with colourful the bottom boats 50 50 cm in diameter how much does the water rise in the overflow pipe in the water is heated from 10 degrees Celsius to 40 degrees Celsius​

Answers

Answer:

The water rises by 4.45 m

Explanation:

Mass is constant

Mass = Volume /Specific Volume

Mass = 200/(1*10^-3*1.001) = 199.8 Kg

Volume after heating = specific volume * mass

= 1.008 *10^-3 lt/gm * 199800 gm

= 201.398 t

Change in volume = 1.3986

(pi)r^2 *h = 1.3986 *10^-3 m^3

3.14 * (1*10^-2 m)^2 *h = 1.3986 *10^-3 m^3

H = 4.45 m

Calculate the refractive index for a substance where the angle of incidence is 300 , the angle of refraction is 600 , and the refractive index of second substance is 1.5

Answers

Answer:

η₁ = 2.6

Explanation:

Here, we will use snell's law to calculate the refractive of the substance:

[tex]\frac{\eta_2}{\eta_1} = \frac{Sin\theta_1}{Sin\theta_2}[/tex]

where,

η₁ = refractive index of first substance = ?

η₂ = refractive index of second substance = 1.5

θ₁ = angle of incidence = 30°

θ₂ = angle of refraction = 60°

Therefore,

[tex]\frac{1.5}{\eta_1} = \frac{Sin\ 30^0}{Sin\ 60^0}[/tex]

η₁ = 2.6

Iron ball sinks in water but not in mercury. Why?
