A monochromatic light passes through a narrow slit and forms a diffraction pattern on a screen behind the slit. As the slit widt

h increases, the diffraction pattern:
O becomes dimmer.
O shrinks with all the fringes getting narrower.
O spreads out with all the fringes getting alternately wider and then narrower.
O remains unchanged.
O spreads out with all the fringes getting wider.

Answer:

shrinks with all the fringes getting narrower

Explanation:

As the light passes through the slit, the diffraction pattern shrinks, as the waves have more opening to penetrate, and the fringes becomes more narrow as a result of that, The opposite happens as the conditions are reversed.

Which of the following statements is/are true? Check all that apply. A nonconservative force permits a two-way conversion betwee
saul85 [17]

Answer:

A conservative force permits a two-way conversion between kinetic and potential energies.

The work done by a nonconservative force depends on the path taken.

A potential energy function can be specified for a conservative force.

Explanation:

A conservative force is defined as a force whose work done does not depend on the path taken, but only on the initial and final position of motion.

This means that for a conservative force, it is possible to defined a potential energy function U which depends only on the position of the object. An example of conservative force is gravity: the gravitational potential energy of an object, in fact, depends only on its position in the field, not on the path taken.

This behaviour also implies that when an object moves from A to B and then back from B to A, the potential energy gained (or lost) moving from A to B is lost (or re-gained) when moving from B to A. This means that the total mechanical energy (sum of kinetic energy and potential energy) of the object is conserved, and therefore there is a constant conversion between potential and kinetic energy during the motion.

A non-conservative force instead does not show this properties, as the work done by it depends on the path taken, and therefore it is not possible to define a potential energy function. An example of non-conservative force is friction.

According to what we wrote above, therefore, the only correct statements are:

A conservative force permits a two-way conversion between kinetic and potential energies.

The work done by a nonconservative force depends on the path taken.

A potential energy function can be specified for a conservative force.

Suppose light from a 632.8 nm helium-neon laser shines through a diffraction grating ruled at 520 lines/mm. How many bright line
Leya [2.2K]

Answer:

1 bright fringe every 33 cm.

Explanation:

The formula to calculate the position of the m-th order brigh line (constructive interference) produced by diffraction of light through a diffraction grating is:

y=\frac{m\lambda D}{d}

where

m is the order of the maximum

\lambda is the wavelength of the light

D is the distance of the screen

d is the separation between two adjacent slit

Here we have:

\lambda=632.8 nm = 632.8\cdot 10^{-9} m is the wavelength of the light

D = 1 m is the distance of the screen (not given in the problem, so we assume it to be 1 meter)

n=520 lines/mm is the number of lines per mm, so the spacing between two lines is

d=\frac{1}{n}=\frac{1}{520}=1.92\cdot 10^{-3} mm = 1.92\cdot 10^{-6} m

Therefore, substituting m = 1, we find:

y=\frac{(632.8\cdot 10^{-9})(1)}{1.92\cdot 10^{-6}}=0.330 m

So, on the distant screen, there is 1 bright fringe every 33 cm.

Can anyone please tell me where these labels would go?
Nadya [2.5K]
The least potential energy would go at the very bottom of the track. the greatest kinetic energy would be on the upper half of the track and the least kinetic energy would be on the lower half of the track. please review this on google if you are not sure.

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
