Beat frequency, fb = |f2-f1|

That is, beat frequency is the absolute difference between two frequencies. Is is as a results of destructive and constructive inferences.

Therefore, in this case:

fb = 203 - 199 = 4 Hz

Question
Extend your thinking: household appliances are usually connected in a parallel circuit. why do you think it might be a problem if too many appliances are turned on at once? (hint: current in a wire also produces heat.)
Solution 1

There might be a problem of a lot of power being dissipated if too many

appliances are turned on at once.

We can infer from Ohm's law that as resistance decreases, the total current increases.

I= V/R

The power dissipated through the circuit is directly proportional to the square

of the current.

P= I²R

We can therefore state that the power dissipated via heat will be much when

too many appliances are turned on at once.

Solution 2
The equivalent resistance of several devices connected in parallel is given by where are the resistances of the various devices. We can see that every time we add a new device in parallel, the term increases, therefore the equivalent resistance of the circuit decreases.

But Ohm's law: tells us that if the equivalent resistance decreases, the total current in the circuit increases. The power dissipated through the circuit (and so, the heat produced) depends on the square of the current: therefore if there are too many devices connected in parallel, this can be a problem because there could be too much power dissipated (and too much heat) through the circuit.

Apply: what will be the total resistance and current in a parallel circuit with a 15-volt battery and three 10-ohm resistors? test your answers with the gizmo.
Solution 1
1) Total resistance

the total resistance of a circuit with n resistors in parallel is given by where are the single resistances.

In our circuit, we have 3 resistors of each, so the total resistance of the circuit is given by which means a total resistance of 2) Current in the circuit

The current in the circuit can be found by using Ohm's law: where V is the voltage of the battery and Req is the total resistance we found before. By using V=15 V, we find Question

Question
What is an advantage of using coal power over solar power to generate electricity
Solution 1

An advantage of using coal power over solar power to generate electricity is Reliable Fuel.

Compared to solar power or wind energy, coal is a reliable, predictable, and dependable fuel. While it may not be at the forefront of national energy production, it can provide invaluable backup service and highly reliable fuel.

### What is coal power ?

"Coal-fired power plants burn coal to make steam and the steam turns turbines (machines for generating rotary mechanical power) to generate electricity." Many industries and businesses have their own power plants, and some use coal to generate electricity for their own use and mostly in combined heat and power plants.

### What is solar power ?

"Solar power works by converting energy from the sun into power." There are two forms of energy generated from the sun for our use – electricity and heat. Both are generated through the use of solar panels, which range in size from residential rooftops to 'solar farms' stretching over acres of rural land.

Question
How does natural selection result in adaptations in a species
Solution 1
An organism's "fitness" is measured by its ability to live long enough to reproduce and pass down traits to their offspring. In sexually reproducing organisms, those who are most fit are most likely to survive often have a specialized trait that gave them the advantage in doing so. The organism with the traits that allowed them to survive and reproduce passes the trait to it's offspring. Assuming that the environment doesn't overly change, those offspring have a greater chance to survive and reproduce themselves. Thus, this trait becomes a specialized adaption for the environment and allows the species as a whole to survive longer.
Question
I need help finding the answer: When a guitar string plays the note "A", the string vibrates at 440 Hz. What is the period of the vibration?
Solution 1
The formula applicable:

Period, T = 1/f --- Where T = period (s), and f = frequency (Hz).

Substituting by use of the values of frequency given in the current scenario,

T = 1/440 = 2.27*10^-3 seconds
Question
Which of the following will induce a reduced emf in the secondary coil of a generator? fewer number of loops in the secondary coil. greater number of loops in the primary coil. larger area in the secondary coil. constant potential in the primary coil.
Solution 1

fewer number of loops in the secondary coil.

Explanation:

The transformer equation states that: where

Vp is the voltage in the primary coil

Np is the number of loops in the primary coil

Vs is the emf induced in the secondary coil

Ns is the number of loops in the secondary coil

Solving the expression for Vs, Therefore, we see that in order to reduce the emf in the secondary coil, we can reduce Ns, the number of loops in the secondary coil. So the correct option is

fewer number of loops in the secondary coil.

Question
Andre heated several solid crystals of a substance called iodine, and the iodine changed directly to a gas. The iodine gas then cooled and changed into droplets. Which two processes did the iodine undergo? A. condensation, then vaporization B. sublimation, then condensation C. deposition, then sublimation D. vaporization, then deposition
Solution 1

The correct choice is

B. sublimation, then condensation

Sublimation is the name of the process where a solid directly converts into gas on heating. on heating solid crystals of iodine directly change into gas. hence this is sublimation.

condensation is the process where gas is converted into liquid on cooling.

here iodine gas is being converted into droplets on reducing the temperature. hence this is condensation.

Solution 2
The answer in B)sublimation, then condensation.
