If both the speed and radius of a circular path of a body  are doubled then centripetal acceleration will also be doubled.

The characteristic of an object moving in a circular path is known as centripetal acceleration. Centripetal acceleration is the term for any moving object whose acceleration vector is directed toward the center of the circle. The centripetal acceleration formula is as follows:

\(a_c=v^2 /r\)

where v is the angular speed and r is the radius.

Now for the given question,

Original centripetal acceleration,

\(a=v^2 /r\)

New centripetal acceleration,

\(a^{'} =(2v)^2 /2r\\\\=2v^2/r\\=2a\)

Hence, centripetal accelearation is also doubled.

By ideal gas approximation, the final pressure is 75.76 atm.

We need to know about the ideal gas theory to solve this problem. The ideal gas is assumed that there is no interaction between particles in a gas. It can be determined by the equation

P . V = n . R . T

where P is pressure, V is volume, n is the number of moles gas, R is the ideal gas constant (8.31 J/mol.K) and T is temperature.

From the question above, we know that

P1 = 50 atm

T1 = 330 K

T2 = 500 K

When the initial and final volume is the same, we can use the ratio of pressure and temperature as

P1 / P2 = T1 / T2

50 / P2 = 330 / 500

P2 = 50 x 500 / 330

A 200 watt to decibels is option (b) 53 dBm.

To convert 200 watts to decibels referenced to 1 milliwatt, we can use the formula:

dB = 10 * log10(P/Pref)

where P is the power being measured (in this case, 200 watts) and Pref is the reference power (1 milliwatt).

First, we need to convert 200 watts to milliwatts. Since 1 watt is equal to 1000 milliwatts, we have:

200 watts = 200 * 1000 = 200,000 milliwatts.

Now we can calculate the decibel value:

dB = 10 * log10(200,000/1)

dB = 10 * log10(200,000)

Using a calculator, the result is approximately 53 dB.

The decibel (dB) is a logarithmic unit used to express the ratio of two power levels. In this case, we are comparing the power of 200 watts to the reference power of 1 milliwatt. By converting the power to decibels, we can more easily express and compare power levels on a logarithmic scale. In telecommunications and electronics, dBm is often used, which is a decibel measurement referenced to 1 milliwatt. In this context, 53 dBm indicates that the power of 200 watts is 53 decibels higher than 1 milliwatt.

Due to heat energy , metal expands . Formula for linear expansion is as follows .

L = l ( 1 + α Δt )

where L is expanded length , l is original length , α is coefficient of linear expansion and Δt is increase in temperature .

To pass the sphere through the ring , the diameter of both ring and sphere should be same after heating . Let after increase of temperature Δt , their diameter becomes same as L  . The linear coefficient of brass and steel are

20 x 10⁻⁶ and 12 x 10⁻⁶ respectively .

For steel sphere ,

L = 25 ( 1 + 12 x 10⁻⁶ Δt )

For brass ring

L = 24.9 ( 1 + 20 x 10⁻⁶ Δt )

25 ( 1 + 12 x 10⁻⁶ Δt ) = 24.9 ( 1 + 20 x 10⁻⁶ Δt )

1.004( 1 + 12 x 10⁻⁶ Δt ) =  ( 1 + 20 x 10⁻⁶ Δt )

1.004 + 12.0482 x 10⁻⁶ Δt  =   1 + 20 x 10⁻⁶ Δt

A left-linear grammar is a kind of grammar in which all the production rules are of type A → aB or A → a, where A and B are non-terminals and a is a terminal symbol.

An NFA (Nondeterministic Finite Automaton) can be transformed into a left-linear grammar using the following steps:

If q0 is the initial state of NFA, S → q0B is the starting rule, where B is the first state reached from q0 using an ε-transition.

If qf is the final state of NFA, then we create a rule of form B → a, where a is the input symbol, and also a rule of form B → aC, where a is the input symbol and C is the state reached from qf after consuming a.

The rest of the rules are generated based on the following principle:

If (p,a,q) is a transition of NFA, then we create a rule of form C → bD, where b is an input symbol, and D is the state reached from q after consuming a.

Consequently, we obtain a left-linear grammar from an NFA directly.

We can directly get left-linear grammar from an NFA by utilizing the above-described method. This is helpful because NFA is more versatile than a grammar, as it can recognize regular languages without needing to explicitly list all of their strings.

In contrast, grammar recognizes the language by explicitly listing all of its strings. A language may have an infinite number of strings, which makes grammar impractical to use in such cases.

Automata, on the other hand, are more practical in this situation because they define languages more naturally, by defining a set of strings that can be accepted by an automaton.

A left-linear grammar can be directly obtained from an NFA using the method described above. This technique is useful because automata are more versatile than grammars, making them more practical for languages with an infinite number of strings.

➝ Equivalent resistance of series connection is given by

➝ We know that, Equal current flow through each resistor in series connection.

➝ As per ohm's law, Current flow through a conductor is directly proportional to the applied potential difference.

◈ Equivalent resistance :

⇒ Req = R1 + R2 + R3

⇒ Req = 5 + 10 + 30

⇒ Req = 45Ω

◈ Current flow in circuit :

⇒ V = IReq

GMm/r = mv². This is the same as the centripetal force equation, which we know to be true since the orbit is circular.

The mass of the earth is M, the gravitational constant is G, and the orbital radius is r. The mass of the satellite is m and its velocity is v. We assume that the orbit is a perfect circle and that the only force acting on the satellite is the gravitational force between the satellite and the earth. We will determine the value of the radius of the orbit (r) in terms of known constants M, m, G and v.

Solve the equation on the far right for v. Then substitute this expression for "v" into the first set of equations. Now solve for "r," the radius of the discrete orbit.

Since the orbit is a perfect circle, the centripetal force is given by F = mv²/r. The gravitational force between the satellite and the earth is given by F = GMm/r². Since these are equal, we can equate these two and get

mv²/r = GMm/r²

Multiplying both sides by r², we get

v²r = GMm

Dividing both sides by v², we get

r = GM/v²

Substituting this value of r in the second equation, we get

F = mv²/GM × v²

Substituting this value of v² from the above equation, we get

F = mGM/r²

Therefore, r = √(GM/F)

According to time dilation, the elapsed time between two events is different for observers in relative motion to each other. The formula for time dilation is given by:

Δt' = Δt / sqrt(1 - v^2/c^2)

where Δt is the time interval measured by the observer in the rest frame, Δt' is the time interval measured by the observer in the moving frame, v is the relative velocity between the two frames, and c is the speed of light.

In this problem, the neutron is at rest relative to the first observer and its lifetime is measured to be 900 s. The neutron is moving relative to the second observer, and its lifetime is measured to be 2065 s. We want to find the velocity v of the neutron relative to the second observer.

We can use the time dilation formula twice, once for each observer:

Δt' = Δt / sqrt(1 - v^2/c^2)

For the first observer (rest frame of the neutron), Δt = 900 s and Δt' = 2065 s (measured by the second observer):

2065 = 900 / sqrt(1 - v^2/c^2)

Simplifying and rearranging:

(1 - v^2/c^2) = (900/2065)^2

1 - v^2/c^2 = 0.155

v^2/c^2 = 0.845

v/c = sqrt(0.845)

v = 0.919c

Therefore, the neutron is moving at a speed of 0.919 times the speed of light relative to the second observer.

The velocity of the boat immediately after the package is thrown with a speed of 10.0 m/s, assuming it was initially at rest and ignoring water resistance, can be calculated using the equation of conservation of momentum.

The equation states that the total momentum of the boat and the package before the throw is equal to the total momentum of the boat and the package after the throw.

In this case, the initial momentum of the boat is 0 since it was initially at rest, and the initial momentum of the package is 0.7 x 10.0 m/s (due to the mass of the package being 5.70 kg and the speed of 10.0 m/s).

The total initial momentum is thus 0.7 x 10.0 m/s. After the throw, the momentum of the package is 0 since it is no longer part of the system, and the momentum of the boat is equal to the momentum of the package before the throw, which is 0.7 x 10.0 m/s. The velocity of the boat after the throw can be calculated by dividing the momentum of the boat (0.7 x 10.0 m/s) by the mass of the boat (50.0 kg). This yields a velocity of 0.14 m/s.
