If they are slightly different, they amplify, they form a bigger wave. We say they have constructive interference.

A student must design an experiment to determine the gravitational mass of an object. Which of the following experiments could t
Elena L [17]

Answer: a. Place the object on one side of a lever at a known distance away from the fulcrum. Place known masses on the other side of the fulcrum so that they are also paced on the lever at known distance from the fulcrum. Move the known masses to a known distance such that the lever is in static equilibrium.

d. Place the object on the end of a vertically hanging spring with a known spring constant. Allow the spring to stretch to a new equilibrium position and measure the distance the spring is stretched from its original equilibrium position.

Explanation:

The options are:

a. Place the object on one side of a lever at a known distance away from the fulcrum. Place known masses on the other side of the fulcrum so that they are also paced on the lever at known distance from the fulcrum. Move the known masses to a known distance such that the lever is in static equilibrium.

b. Place the object on a surface of negligible friction and pull the object horizontally across the surface with a spring scale at a non constant speed such that a motion detector can measure how the objects speed as a function of time changes.

c. Place the object on a surface that provides friction between the object and the surface. Use a surface such that the coefficient of friction between the object and the surface is known. Pull the object horizontally across the surface with a spring scale at a nonconstant speed such that a motion detector can measure how the objects speed as a function of time changes.

d. Place the object on the end of a vertically hanging spring with a known spring constant. Allow the spring to stretch to a new equilibrium position and measure the distance the spring is stretched from its original equilibrium position.

Gravitational mass simply has to do with how the body responds to the force of gravity. From the options given, the correct options are A and D.

For option A, by balancing the torque, the mass can be calculated. Since the known mass and the distance has been given here, the unknown mass can be calculated.

For option D, here the gravitational force can be balanced by the spring force and hence the mass can be calculated.

How is aperture measured? What do the measurements mean?
gulaghasi [49]
Aperture is measured in F-stops, in which the f-stops is the amount of light allowed to pass through the aperture, which simply put means that the smaller the aperture, the higher the f-stops. What it does is reduce the amount of light that reaches the film, so the higher the f-stops, the less light reaches the film.

A solenoid with 385 turns per meter and a diameter of 17.0 cm has a magnetic flux through its core of magnitude 1.28 × 10-4 (T·m
shepuryov [24]

Answer:

(a)The current passes through the solenoid is 11.7 A.

(b) The new current will be one-fourth of the initial current.

Explanation:

Given that,

The number of turns per meter = 385

Diameter of solenoid = 17.0 cm = 17\times 10^{-2} m

Magnetic flux  through core of solenoid \phi = 1.28\times 10^{-4} Tm²

(a)

Magnetic field B= \mu_0nI

\mu_0= 4\pi \times 10^{-7} T/amp m

Cross section area of the solenoid A= \pi \frac{d^2}{4}

                                                             =\pi\frac{ (17\times 10^{-2})^2}{4}  m²

The angle between magnetic field and cross section of the solenoid is \theta =0^\circ

The magnetic flux through a area A with magnetic fie;d B is

\phi = BA cos\theta

\Rightarrow \phi =( \mu_0nI)(\pi \frac{d^2}4)cos \theta

\Rightarrow I =\frac{\phi}{(\mu_0\pi n \frac{d^2}4cos\theta)}

       =\frac{4\phi}{(\mu_0n)(\pi d^2)cos\theta}

      =\frac{1.28\times 10^{-4}\times 4}{(4\pi \times10^{-7}\times385 )\times(\pi\times17\times 10^{-2})^2cos 0^\circ}

     =11.7 A

The current of the solenoid is 11.7 A.

(b)

I =\frac{4\phi}{(\mu_0\pi n d^2cos\theta)}

From the above equation it is clear that, the current is inversely proportional to the square of the diameter of a solenoid.

I\propto \frac1{d^2}.

Consider d' be the new diameter of the solenoid .

Since the new diameter of the solenoid is double of the initial diameter.

That is d'= 2d.

\frac{I}{I'}= \frac{(d')^2}{d^2}

\Rightarrow \frac{I}{I'}=\frac{(2d)^2}{d^2}

\Rightarrow \frac{I}{I'}=4

⇒I=4I'

\Rightarrow I'=\frac{I}{4}

The new current will be one-fourth of the initial current.
