The final pressure of a sample of a gas (5.0 mol) at 1.0 atm is expanded at constant temperature from 10 l to 15 l is 0.67 atm

Boyle's law states that at constant temperature of a given mass of confined gas, the product of its pressure and volume is also constant. Let P1 and V1 be the initial pressure and volume of the gas and P2 and V2 be the final pressure and volume of the gas.

P1 = 1 atm

V1 = 10 l

V2 = 15 l

According to Boyle's law,

P1 V1 = P2 V2

1 * 10 = P2 * 15

P2 = 10 / 15

P2 = 0.67 atm

Therefore, the final pressure is 0.67 atm

What is force?

Force is the push or pull on any given object that can change the velocity of the object. It has both magnitude and direction which has the formula F = ma, where F is force, m is mass and a is acceleration.

Let the force be at angle θ to be horizontal. The block is in equilibrium, so

The possible distance from the person to the other speaker is c) 8.1m

To determine the possible distance we first convert the frequency from kHz to Hz as follows;

As 1 kHz = 1000 Hz

Therefore; 0.50 kHz = 0.50 × 1000 = 500 Hz

Now we determine the wavelength as follows;

wavelength = v ÷ f

wavelength = 340 ÷ 500

wavelength = 0.68 meters

Half wavelength = 0.5 × wavelength = 0.5 × 0.68 = 0.34 meters

For the sound interference to be destructive, the second source must be an odd multiple of 1/2 wavelength away from the first, therefore we calculate the possible distance from the person to the other speaker as follows;

distance between the person and speaker + odd multiple of wavelength = possible distance from other speaker

5 m + 0.34 m = 5.34 m

5 m + 3 × 0.34 m = 6.02 m

5 m + 5 × 0.34 m = 6.7 m

5 m + 7 × 0.34 m = 7.38 m

5 m + 9 × 0.34 m = 8.06 m  

5 m + 11 × 0.34 m = 8.74 m

One end of the taut cable is pulled, causing a transverse pulse to be created. In 0.835 seconds, the pulse travels four times down the cable and four times back then the tension in the ethernet cable is determined as 67 N.

It is given to us that -

Ethernet cable is 3.90 m long => l = 3.90 m

and has a mass of 0.190 kg => m = 0.190 kg

It is also given that the transverse pulse makes four trips down and back along the cable in 0.835 s.

=> time taken, t = 0.835 s

We have to find out the tension in the cable.

We know that

Speed = Distance/Time ----- (1)

Since the transverse pulse applied on the ethernet cable makes four trips down and back along the cable, the total distance travelled by the pulse = 4 * (2l)

Now, using equation (1) we can find out the speed of the pulse by -

[tex]v = \frac{4*2*3.90}{0.835} \\= > v = 37.36[/tex] m/s ---- (2)

We also know that the mass density of the pulse can be determined by the formula -

μ = [tex]\frac{m}{l}[/tex] ------ (3)

where,

m = mass of the cable

l = length of the cable

Substituting the given values of mass and length of the cable in equation (3), we can find out the mass density of the pulse as -

μ = [tex]\frac{m}{l} = \frac{0.190}{3.90} = 0.048[/tex] kg/m ------ (4)

We also know that the tension in the cable can be represented by the formula -

T = μ[tex]v^{2}[/tex]  ----- (5)

Substituting the values of v and μ from equations (2) and (4) respectively, we can find out the tension in the cable as -

T = μ[tex]v^{2}[/tex]

Magnitude of Charge (Q) = 290 pc

Potential difference between plates (V) = 41.0 V

Let capacitance be = C

Using the relationship between charge and potential difference,

= Q = C × V

= C = Q / V

= C = 290 × 10⁻¹² / 41

= C = 7.07 × 10⁻¹² F

Now, we know that C = (ε × A) / d

Here, Area (A) = 6.80 cm² and

Distance = d

Thus, distance =

= d = (ε × A) / C

= d = (8.85 × 10⁻¹² × 6.80 × 10⁻⁴) / (7.07 × 10⁻¹²)

= d = 8.51 × 10⁻⁴ m

= d = 8.51 mm

Using Q = C × V,

= V = Q/C

If the separation between the two plates is doubled, then the capacitance is halve of the original value.

Thus, new V =

The frequency of revolution of an electron with an energy of 100 ev in a uniform magnetic field of magnitude 35.0 mt is 9.78 x 10^5 Hz

What is cyclotron frequency?

A charged particle travelling perpendicular to the direction of an even magnetic field has a frequency that is known as the cyclotron frequency or gyrofrequency (constant magnitude and direction). The cyclotron frequency is determined by the centripetal force and magnetic Lorentz force being equal because that motion is always circular.

Kinetic Energy of the electron = 100 ev

                                                   = 100×(1.60×10^−19 J)

                                                   = 1.60×10 ^−17 J

The expression of kinetic energy of the electron in terms of the velocity-

E = mv^2/2

v = (2E/m)^1/2

Putting the values in the above expression we obtain the value of v,

v = ( 2 x 1.60 x 10 ^−17/ 9.1 x 10^-31)^1/2

  = 5.92 x 10^6 m/s

The radius of the circular path the electron moves inside a magnetic field is given as-

r = mv / eB

Putting the values we find,

r = (9.11×10^−31  kg)(5.92×10^6m/s)/ (1.6 x 10^-19 C)(35 x 10^-6 T)

 = 0.963 m

The orbital frequency is same as the velocity of the electron when it moves over the circular path, which is given as-

f = v / 2πr

 = (5.92×10^6 m/s)​/2π(0.963 m)

 = 9.78 x 10^5 Hz

Hence, the required frequency is 9.78 x 10^5 Hz

1.167[tex]cm^{3}[/tex]  × [tex]\frac{1 mL }{ 1cm^{3} }[/tex]× [tex]\frac{1L}{1000mL}[/tex]= 0.0011667 L

Ratio:   [tex]\frac{V gas}{V solid}[/tex]

([tex]\frac{0.85 L}{0.0011667 L}[/tex]) = 728.55
