Fig. 62.7 A C₁2V 50 V 5₁ 30 (a) Calculate the readings of the ammeter and the voltmeter when the switches are as shown with S closed and S₂ open. Explain your calculations.​

Answers

The reading on the ammeter will be 10 A.The reading on the voltmeter will be 50 V.

What is ammeter?

Generally, To solve this problem, we need to first analyze the circuit and determine the current and voltage at various points.

Starting at the left side of the circuit, we have a 50 V battery with its positive terminal connected to a resistor and its negative terminal connected to a switch. When the switch is closed, this allows current to flow from the battery through the resistor. The current will be given by Ohm's law:

I = V/R

Where I is the current, V is the voltage (50 V in this case), and R is the resistance of the resistor (5Ω in this case). Plugging in these values, we get:

I = 50 V / 5Ω = 10 A

Next, we need to determine the voltage across the resistor. This can be found using Ohm's law again:

V = IR

Where V is the voltage across the resistor, I is the current through the resistor (10 A in this case), and R is the resistance of the resistor (5Ω in this case). Plugging in these values, we get:

V = 10 A * 5Ω = 50 V

Since the voltage across the resistor is equal to the voltage of the battery, we know that the current through the resistor must be flowing in the same direction as the battery's current.

The ammeter in the circuit is connected in series with the resistor, so it will measure the current flowing through the resistor. Therefore, the reading on the ammeter will be 10 A.

The voltmeter is connected in parallel with the resistor, so it will measure the voltage across the resistor. Therefore, the reading on the voltmeter will be 50 V.

The law of conservation of linear momentum states that the sum of the initial momentum is equal to sum of the final momentum, provided that the system is Isolated.

Mathematically, the law of conservation of linear momentum is given as;

Pi = Pf

g calculate the mass-to-light ratio for a globular cluster with a luminosity of 106 lsun and 105 stars. (assume that the average mass of a star in such a cluster is 1 msun.)

Answers

The mass-to-light ratio for a globular cluster is equal to 137.7 kg/lsun

To measure the mass-to-light ratio of a globular cluster, we first determine the total mass of the cluster. Since the cluster has 105 stars, and the average mass of a star in the cluster is 1 m-sun, therefore, the total mass of the cluster is 10^5 * 1 msun = 10^5 msun.

Now, we convert the luminosity of the cluster from solar units to kilograms. The luminosity of the cluster is given as 10^6 lsun, which is equal to 10^6 * 3.828 x 10^26 W.

Using the equation, [tex]E = mc^2[/tex], we can convert this energy to mass:

[tex]mass = (luminosity * time) / (c^2)[/tex]

where, c is the speed of light (3 x 10^8 m/s) and time is the amount of time over which the luminosity is measured (here, time is equal to 1 second).

Substituting the values in above equation, we find that the mass of the cluster in kilograms is approximately 1.45 x 10^31 kg.

To determine the mass-to-light ratio, divide the total mass of the cluster (in kilograms) by its luminosity (in solar units):

mass-to-light ratio = (total mass of cluster in kg) / (luminosity in solar units)

Substituting the values in above equation, we find that the mass-to-light ratio for this globular cluster is approximately:

1.45 x 10^31 kg / 10^6 lsun = 137.7 kg/lsun.

Probability refers to potential.  The range of the value is 0 to 1. Mathematics has included probability to forecast the likelihood of certain events. The degree to which something is likely to happen is basically what probability means.

The Schrödinger equation is a linear partial differential equation that describes the wave function or state function of a quantum-mechanical system.

To find the most probable distance, differentiate the equation |Ψ(1s)|²x² with respect to x and equating to zero, we get

According to Newton's third law,

Given that a soccer player runs at 10m/s and plows into a 80kg referee standing on the field causing the referee to fly forward at 56m/s. Let

mass of the player = ?

initial velocity of the player = 10m/s

Final velocity of the player

mass of the referee = 80 kg

Initial velocity of the referee = 0 ( since he is at rest )

Final velocity of the referee = 6 m/s

Since it is a perfectly elastic collision,

U1 =V2 - V1 ........ (1)

M1U1 = M2V2 + M1V1........ (2)

Substitute all the necessary parameters into the equation (1)

10 = 6 - V1

V1 = 10 - 6

V1 = 4 m/s

Now, Substitute all the necessary parameters into the equation (2)

10M1 = (80 x 6) + (4M1)

10 M1- 4 M1 = 480

4M1 = 480

M1 = 480/4

M1 = 120kg

4. For an ideal gas, the specific heat at constant pressure Cp is greater than the specific heat at constant volume CV because the A. pressure of the gas remains constant when its temperature remains constant B. gas does work on its environment when its pressure remains constant while its temperature is in creased C. increase in the gas's internal energy is greater when the pressure remains constant than when t he volume remains constant D. heat input per degree increase in temperature is the same in processes for which either the pressure or the volume is kept constant

Answers

Whenever the gases are heated at a fixed volume, no outside work is done as well as the heat energy given is simply used to make the gas more energetic internally.

Why is CP for just an ideal gas higher than Cv?

The specific heat under constant pressure for an ideal gas, Cp, is higher than Cv.This is due to the fact that when the gas' temperature rises while the pressure stays constant, the gas must perform some finite work on its surroundings.

Does CP always exceed Cpk?

When the goal value and the specification's average are equal, Cpk equals Cp.Never can Cpk go above Cp.With the creation of descriptive statistic displays and histograms, Cp and Cpk can both be determined.

when a man loves a magnetic continually changes magnitude and direction a voltage is continually being induced in the coil this voltage is called voltage

Answers

When a magnetic field continually changes magnitude and direction, a voltage is continually induced in the coil. This voltage is called induced voltage.

Induced voltage is the type of voltage that is a product of electromagnetic induction. It is generally defined as the rate of change of magnetic flux with respect to time via a closed circuit.

A wire that is carrying a current will experience an induced voltage along its length if the current changes. The changes in current change the magnetic field flux perpendicular to the wire.

Induced voltage is calculated using the Faradays equation:

e = N(dΦ/dt)

e = induced voltage (volts).N = number of turns in the wire coil.Φ = magnetic flux (webers).t = time (seconds)
