Answer : The correct option is, (B) 1, 4, and 6

Explanation :

Boyle's Law : It is defined as the pressure is inversely proportional to the volume of the gas at constant temperature and number of moles.  In this volume of gas changes.

P\propto \frac{1}{V}

Charles' Law : It is defined as the volume is directly proportional to the temperature of the gas at constant pressure and number of moles.  In this volume of gas changes.

V\propto T

Gay-Lussac's Law : It is defined as the pressure is directly proportional to the temperature of the gas at constant volume and number of moles. In this volume of gas is constant.

P\propto T

Therefore, the volume should be placed in cell numbered 1, 4, and 6.

Two fire trucks have sirens that emit waves of the same frequency. As the fire trucks approach a person, the person hears a high
Mumz [18]

Answer:

Only option A is correct

Explanation:

From the concept of Doppler effect, only speed matters. Thus, the faster a vehicle is moving, the closer together the sound waves get compressed and the higher the frequency. For example, for a very fast vehicle traveling at the speed of sound; the compressions are all right on top of each other. Thus, faster speed means closer compressions and higher frequencies. Hence, option only option A must be true because X is a higher frequency and so it must be going faster. The distance to the person will affect the volume but will not the pitch so Option B is not correct. Option C too is not correct because It doesn’t matter whether you are speeding up or slowing down, it only matters who is going faster. For example, from option c concept, if truck X was going 10 m/h and speeding up while truck Y was going 50 mph and slowing down, it would not meet the requirement that X has a higher frequency because only actual speed matters, not what is happening to that speed. Thus only option A is the correct answer

When the distance between two objects doubles, what happens to the gravitational attraction between these two objects?
Feliz [49]

Answer:

As indicated by Newton's law of attraction each article or body in the universe draws in every single item towards one another and that power of fascination is straightforwardly relative to the result of their masses and contrarily corresponding to the square of the distance between them.  

The power of gravity between two articles will diminish as the distance between them increments. The two most significant elements influencing the gravitational power between two items are their mass and the distance between their focuses. As mass increments, so does the power of gravity, however an increment in distance mirrors a reverse proportionality, which makes that power decline dramatically.  

At that point by Newton's All inclusive Law of Attractive energy;  

F=GMm/R^2  

Mm= result of the majority  

R=Distance Between the two masses by focus.  

On the off chance that R is multiplied, new force=GMm/(2R)^2  

=GMm/4R^2  

Unique Power/New Force=4/1  

F/4=New Power

A series RCL circuit includes a resistance of 280, an inductive reactance of 508, and a capacitive reactance of 315. The current
cestrela7 [59]

Answer:

The voltage of the generator is 88.53volts

Explanation:

The voltage across the RLC AC circuit will be the voltage across the generator. It is expressed as

V = IZ and

Z² = R² + (Xl-Xc)²

Z = √R² + (Xl-Xc)² where;

Z is the impedance that oppose the flow of current in the resistor, capacitor and inductor in the circuit

I is the total current = 0.312A

R is the resistance in the circuit = 280ohms

Xl is the inductive reactance = 508ohms

Xc is the capacitive reactance = 315ohms

Substituting to this parameters to get the impedance Z we have;

Z = √280²+(508-315)²

Z = √208²+(193)²

Z = √80,513

Z = 283.75ohms

The voltage V of the generator = current × impedance

V = 0.312×283.75

V = 88.53Volts

The voltage if the generator is 88.53volts
