⠀⠀⠀⠀■ Solution

⠀

[tex] \textsf{ As here, we can see in the above diagram} \\ \\ \sf R_1 \: and \: R_2 \: both \: are \: in \: series. \\ \\ \textsf{ So their total resistance will be} \: R_s[/tex]

So for formula for series will be

[tex] \sf R_s = R_1 + R_2 \\ \\ \sf R_s = 100 + 200 \\ \\ \boxed {R_s = 300Ω}[/tex]

⠀

[tex] \sf As \: you \: can \: also \: see \: here , \\ \\ \sf R_s \: is parallel \: with \: R_3 \\ \\ \sf So \: their \: total \: resistance \: R \: will \: be[/tex]

⠀

[tex] \sf \frac{1}{R } = \frac{1}{R_3} + \frac{1}{R_s } \\ \\ \sf \frac{1}{R} = \frac{1}{600} + \frac{1}{300} \\ \\ \sf \frac{1}{R} = \frac{1 + 2}{600} \\ \\ \sf \frac{1}{R} = \frac{ \cancel3}{ \cancel{600} \: \: \small{200}} \\ \\ \sf \frac{1}{R} = \frac{1}{200} \\ \\ \boxed{ \tt{R = 200Ω}} [/tex]

⠀

⠀

So the total resistance will be 200Ω.

Explanation:

Frequencies would show resonance will be 30 Hz,45 Hz and 60 Hz. Option B and E are correct.

Mechanical systems and charged particles all have a frequency that they vibrate at. this frequency is referred to as the resonance frequency or natural frequency.

When the matching vibrations of another item enhance the amplitude of an object's oscillations, this is known as resonance.

15 Hz is the fundamental frequency of the string.

Higher frequencies, such as the first overtone, second overtone, third overtone, and so on, must be used to cause the string to vibrate in a resonant manner.

F₁ = 2F₀ = 2 x 15 = 30 Hz is the initial overtone.

F₂ = 3F₀ = 3 x 15 = 45 Hz is the second overtone.

F₃ = 4F₀ = 4 × 15 = 60 Hz is the third overtone.

Hence,frequencies would show resonance will be 30 Hz,45 Hz and 60 Hz. Option B and E are correct.

The force exerted by the output piston will be 20 N. The pressure exerted on the both end is equal.

The force applied perpendicular to the surface of an item per unit area across which that force is spread is known as pressure.

It is denoted by P. The pressure relative to the ambient pressure is known as gauge pressure.

The area of the input cylinder is found as;

A₁=πR₁²

A₁=π(2)²

A₂=4π

The area of the output cylinder is found as;

A₂=πR₂²

A₂=π(4)²

The difference between an electrician and an electrical engineer is the way of working towards a common electrical project.

An engineer is a person who performs a function like designing, building, or maintaining engines, machines, or structures.

Electrical engineers and electricians both commonly involved in the process of creating and installing critical electrical systems.

An electrical engineer can design electronics and is familiar with the working of electrical parts.

An electrician is much more like a builder. They take the designs from electrical engineer and follow them to create, repair, or revise actual electrical systems.

Thus,  the difference between an electrician and an electrical engineer is the way of working towards a common electrical project.

The wavelength of the wave which is travelling along right with speed of 0. 5 m/s time 4 second point is 2.

Speed of wave is the rate by which the wave travels. It can be described as the distance cover by the crest or thrust of it per unit of time. It can be calculated with the following formula,

[tex]v=f\times\lambda[/tex]

Here, (f) is the frequency and (λ) is the wavelength.

The frequency is inverse of time. Thus, the value of frequency in time t is,

[tex]f=\dfrac{1}{t}\\f=\dfrac{1}{4}\\f=0.25[/tex]

The speed of the wave is 0.5 m/s. Put the values in the formula,

[tex]v=f\times\lambda\\0.5=0.25\times\lambda\\\lambda=\dfrac{0.5}{0.25}\\\lambda=2[/tex]

Thus, the wavelength of the wave which is travelling along right with speed of 0. 5 m/s time 4 second point is 2.

Explanation:

Newtons are used to measure force.

The total energy available during the collision of the two protons is determined as 900,938 MeV.

Based on the principle of conservation of energy, the total energy of the two protons during the collision will be conserved.

Available energy = Er + K

Where;

Available energy = 938 MeV + 900 GeV

Available energy = 938 Mev + 900 x 10³ MeV

Available energy = 938 MeV + 900,000 MeV

Available energy = 900,938 MeV

When the outward-directed gas pressure (created by thermal nuclear energy) is balanced in a stable relationship with inward-directed gravitational force results in main sequence star.

The pressure is the force exerted per unit area.

A main sequence star fuses hydrogen in its core and has balanced outward pressure from core nuclear fusion and gravitational forces will be pushing inward.

The phenomenon of inducing voltage by changing the magnetic field around a conductor will be Electromagnetic Induction. Option B is correct.

According to Faraday's law of electromagnetic induction, the rate of change of magnetic flux link with the coil is responsible for generating emf in the coil to result in the flow of amount of current .

So in order to increase the current, we need to increase the EMF;

so we can increase it by;

1) Increasing the number of turns

2) Increase the area of the loop

3) By moving the magnet faster

Hence, option B is correct.

Hi there!

We can use Faraday's Law to solve:

[tex]\epsilon = N\frac{d\Phi _B}{dt}[/tex]

ε = Induced emf (? V)

N = Number of loops (1 loop)

ΦB = Magnetic flux (Wb)

We know that:

[tex]\Phi_B = \oint B \cdot dA = B\cdot A[/tex]

Since the area of the loop remains the same, we can take this out of the time derivative.

We get:
[tex]\frac{d\Phi_B}{dt} = A * \frac{dB}{dt}[/tex]

Also, since N = 1, we can now rewrite the equation for the induced emf as:
[tex]\epsilon = A * \frac{dB}{dt}[/tex]

dB/dt is equivalent to the change in the magnetic field with respect to time:
[tex]\Delta B = \frac{B_f - B_i}{\Delta t}\\\\\Delta B = \frac{3 - 2}{5} = 0.2 \frac{T}{s}[/tex]

Now, substitute this value into the equation for induced emf:
[tex]\epsilon = \pi (0.3^2) * (0.2) = \boxed{0.0565 V}[/tex]

**Also, since the magnetic field INCREASED out of the page, this change in magnetic flux will create an induced CLOCKWISE current that produces a magnetic field into the page in order to oppose the increase in magnetic flux OUT of the page.

explanation

When heat energy is added to a substance, the temperature will change by a certain amount. The relationship between heat energy and temperature is different for every material, and the specific heat is a value that describes how they relate.

heat energy = (mass of substance)(specific heat)(change in temperature)

Q = mc∆T

Q = heat energy (Joules, J)

m = mass of a substance (kg)

c = specific heat (units J/kg∙K)

∆ is a symbol meaning "the change in"

Why is the moon’s force of gravity less than that of the earth?

Since the moon has a smaller mass than the earth, the moon has less gravity than the earth. Gravity is related to mass.

Larger mass = larger gravity

Smaller mass = lesser gravity

Moon has small mass, therefore less gravity.

Angular frequency in radian per second for 20 vibrations in 10 seconds is 12.6 rad/s

Angular frequency is the number of vibrations in radian per second.

The total number of vibrations n is 20 and the time taken for these vibrations is 10 s

The frequency of the vibrations will be

f = 20 / 10 = 2 Hz

Angular frequency is related to the frequency as

ω = 2πf

ω=2π × 2

ω = 12.6 rad/s

Thus, the angular frequency is 12.6 rad/s.
