Water waves are waves because the wave moves up and down. transverse longitudinal​

Answer:

he wavelength is different (greater) than the wavelength of the incident photon

Explanation:

The Compton effect is the scattering of a photon by an electron, this process is analyzed using the conservation of momentum, in which we assume that initially the electron is at rest and after the collision it recedes, therefore the energy of the incident photon decreases and consequently its wavelength changes

To complete the sentence we use the wavelength is different (greater) than the wavelength of the incident photon

Answer:

The thickness is  [tex]\Delta y = 2.4 *10^{-6} \ m[/tex]

Explanation:

From the question we are told that

   The wavelength is  [tex]\lambda = 480 \ nm = 480*10^{-9} \ m[/tex]

    The first order of the dark  fringe is  [tex]m_1 = 16[/tex]

     The second order of dark fringe considered is  [tex]m_2 = 6[/tex]

Generally the condition for destructive interference is mathematically represented as

        [tex]y = \frac{m \lambda}{2}[/tex]

Here y is the path difference between the central maxima(i.e the origin) and any dark fringe

So  the path difference between the 16th dark fringe and the 6th dark fringe is mathematically represented as

      [tex]y_1 - y_2 = \Delta y = \frac{m_1 \lambda}{2} - \frac{m_2 \lambda}{2}[/tex]

=>  [tex]y_1 - y_2 = \Delta y = \frac{16 *480*10^{-9}}{2} - \frac{6 *480*10^{-9}}{2}[/tex]

=>  [tex]y_1 - y_2 = \Delta y = 5 (480*10^{-9})[/tex]

=>  [tex]\Delta y = 2.4 *10^{-6} \ m[/tex]

Answer:

It is the same in magnitude and opposite in direction.

Explanation:

The gravitational force the moon and the earth exert on each other are equal.

According to Newton's third law of motion, action and reaction are equal and opposite.

The gravitational force the earth exerts on the moon is equal in magnitude but opposite in direction to the gravitational force the moon exerts on the earth.

The magnitude of the gravitational force between the moon and the earth is calculated as follows;

[tex]F = \frac{GM_e M_m}{R^2}[/tex]

Thus, the gravitational force the moon and the earth exert on each other are equal.

Answer:

The displacement of the train in this time period is 2,616.86 m.

Explanation:

A Uniformly Varied Rectilinear Motion is Rectilinear because the mobile moves in a straight line, Uniformly because of there is a magnitude that remains constant (in this case the acceleration) and Varied because the speed varies, the final speed being different from the initial one.

In other words, a motion is uniformly varied rectilinear when the trajectory of the mobile is a straight line and its speed varies the same amount in each unit of time (the speed is constant and the acceleration is variable).

An independent equation of useful time in this type of movement is:

[tex]vf^{2} =vi^{2} +2*a*d[/tex] Expression A

where:

The equation of velocity as a function of time in this type of movement is:

vf=vi + a*t

So the velocity can be calculated as: [tex]a=\frac{vf-vi}{t}[/tex]

In this case:

Replacing in the definition of acceleration:  [tex]a=\frac{42.4 m/s-27.5 m/s}{75 s}[/tex]

a=0.199 m/s²

Now, replacing in expression A:

[tex](42.4 m/s)^{2} =(27.5 m/s)^{2} +2*(0.199 m/s^{2}) *d[/tex]

Solving:

[tex]d= \frac{(42.4 m/s)^{2} - (27.5 m/s)^{2} }{2*(0.199 m/s^{2}) }[/tex]

d= 2,616.86 m

The displacement of the train in this time period is 2,616.86 m.

      [tex]\sum f_x=300 *1.5[/tex]

      [tex]\sum f_x=450N[/tex]

Hence

     [tex]R= 450\=i +259.81\=i[/tex]

     [tex]R=\sqrt{450^2+259.8^2}[/tex]

Answer: D) Mass, speed and radius all impact the centripetal force

Explanation:

If we change either the mass, speed, and/or radius, then the centripetal force will be different. Though on rare occasions we could change the variables together in a way to have the centripetal forces line up, but in general the before and after forces will likely be different. Changing one variable at a time only will definitely result in a different centripetal force.

This is because the centripetal force F is determined by the formula

F = (m*v^2)/r

where,

m = mass

v = velocity

r = radius

Answer:

2. ahead of the package.

Explanation:

Using y' - y = ut - 1/2gt², we find the time, t it takes the package to hit the ground. So, u = initial vertical velocity of package = 0 m/s, y = initial position of package = 3970 m, y' = final position of package = 0 m, g = acceleration due to gravity = 9.8 m/s².

Substituting the variables into the equation, we have

y' - y = ut - 1/2gt²

0 m - 3970 m = 0t - 1/2 × (9.8 m/s²)t²

-3970 m = -(4.9m/s²)t²

t² = -3970 m ÷ -4.9 m/s²

t² = 810.2 s²

t = √810.2 s²

t = 28.5 s

Using v = u' + at, we find the horizontal acceleration of the plane. Since the initial horizontal velocity of the package is that of the plane, u' = 162 m/s, v = 0 m/s since the package stops and t = 28.5 s when the package stops.

So, a = (v - u')/t

a = (0 m/s - 162 m/s)/28.5 s

a = -162 m/s/28.5 s

a = -5.68 m/s²

Using v² = u'² + 2as, we find the horizontal distance ,s where the package stops.

So, s =  (v² - u'²)/2a

Substituting the values of the variables, we have

s =  ((0 m/s)² - (162 m/s)²)/(2 × -5.68 m/s²)

= - 162 m²/s²/(-11.36 m/s²)

= 14.26 m

The horizontal distance d the plane moves after releasing the package is d = u't = 162 m/s × 28.5 s = 4617 m

Since d = 4617 m > s = 14.26 m, the plane would be ahead of the package when the package hits the ground.

Answer:

D = 3.81 x 10⁻² m = 3.81 cm

Explanation:

We can use the formula of fringe spacing from Young's Double Slit experiment to answer this question:

[tex]\Delta x = \frac{\lambda L}{d}\\[/tex]

where,

Δx = distance between two consecutive dark fringes

λ = wavelength of light beam = 5.37 x 10⁻⁷ m

L = Distance between screen and slits = 2.14 m

d = slit separation = 6.03 x 10⁻⁵ m

But, we need the distance between first dark fringe on 1 side to 2nd dark fringe on other side. It means we need twice the distance between two dark fringes:

[tex]D = 2\Delta x = 2\frac{\lambda L}{d}\\[/tex]

where,

D = distance between first dark fringe on one side and 2nd dark fringe on other side of central maximum = ?

Therefore,

[tex]D = \frac{(2)(5.37\ x\ 10^{-7} m)(2.14\ m)}{6.03\ x\ 10^{-5}\ m }[/tex]

D = 3.81 x 10⁻² m = 3.81 cm

Answer:

|B - A| = 12.92 units

Explanation:

In order to find the magnitude of B-A vector, we first write A and B in Vector Notation:

A = Aₓ i + Ay j

A = 7.6 i - 9.2 j

B = Bₓ i + By j

B = -5.1 i - 6.8 j

So, there difference will be:

B - A = (-5.1 i - 6.8 j) - (7.6 i - 9.2 j)

B - A = -12.7 i + 2.4 j

Now, the magnitude of this vector can be found out by using the formula:

|B - A| = √[(x-component)² + (y-component)²]

|B - A| = √[(-12.7)² + (2.4)²]

|B - A| = 12.92 units

We will see that the magnitude of the difference of the vectors is 12.92

Here we have two vectors:

A = <7.6, -9.2>

B = <-5.1, -6.8>

To get the difference we just subtract the correspondent components:

B - A = <Bx - Ax, By - Ay> = <-5.1 - 7.6, -6.8 - (-9.2)> = <-12.7, 2.4>

The magnitude of that vector is just:

[tex]M = \sqrt{(2.4)^2 + (-12.7)^2} = 12.92[/tex]

Gravitational potential energy

= mgh

= (2kg)(10N/kg)(5m)

= 100J.

Answer:

[tex]\boxed {\boxed {\sf 100 \ Joules}}[/tex]

Explanation:

Gravitational potential energy can be found using the following formula.

[tex]E_p=m*g*h[/tex]

where m is the mass, g is the gravitational acceleration, and h is the height.

The mass of the ball is 2 kilograms, its height is 5 meters, and the acceleration due to gravity is 10 Newtons per kilogram.

[tex]m= 2 \ kg \\h= 5 \ m \\g= 10 \ N/kg[/tex]

Substitute the values into the formula.

[tex]E_p=(2 \ kg)(10 \ N/kg)(5 \ m)[/tex]

Multiply the first 2 numbers. The kilograms (kg) will cancel out when multiplying.

[tex]E_p=(20 \ N)(5 \ m)[/tex]

Multiply again.

[tex]E_p=100 \ N*m[/tex]

[tex]E_p= 100 \ J[/tex]

The gravitational potential energy of the ball is 100 Joules.

Answer:

See the explanation below

Explanation:

No matter at what height a body is dropped, the body will always accelerate to the same reason, which corresponds to Earth's gravitational acceleration.

g = 9.81 [m/s²]

That is, in the first second the velocity is 9.81 [m/s] = 9.81 [m/s²] x 1 [s]

Now in the second 2; 19.62 [m/s²] = 9.81 [m/s²] x 2 [s]

And in the third second 29.43 [m/s²] = 9.81 [m/s²] x 3 [s]

And etc.

The speed with which the auto was going when it left the road will be 29.3 m/s.

Acceleration is the rate of change of velocity of an object. Acceleration is a vector quantity as it has both the magnitude and direction. The SI unit of acceleration is meter per second square.

From the given question, we can deduce that the only force which will be acting on the car is the gravitational force and as such the acceleration during free fall of the object will be equal to the acceleration due to gravity acting on the object however, this will be negative since it is towards the ground surface.

Thus, acceleration of the auto = - 9.8 m/s²

The time in which the auto falls will be,

t² = 2 × s/ a

t² = 2 × -43.9/ -9.80

t² = 8.95

t =[tex]\sqrt{8.95}[/tex]

t = 2.99 seconds

The velocity with which the auto will be going when it left the road will be,

Velocity = Displacement/ Time

Velocity = 87.7/ 2.99

Velocity = 29.3 m/s

Therefore, the velocity with which the auto will be moving when it left the road will be 29.3 meters per second.
