The displacement of the cyclist from point A to B is 39.3 m.

The displacement of the cyclist is equal to the change between the final position and initial position of the cyclist. This can also be described as the shortest distance between two positions.

From the given image, the displacement of the cyclist from point A to B can be determined by formula for calculating length of arc,

D = (θ/360) x 2πr

D = (90/360) x 2π x 25

D = 39.3 m

Thus, the displacement of the cyclist from point A to B is 39.3 m.

Answer:

acceleration equal to 0.5 m / s

Explanation:

since 20 x 0.5 = 10

Answer:

Yes it is possible. An object can have a negative acceleration (deceleration) and change its direction. Take for example a car decelerating from 5 m/s to a speed of 1 m/s and then taking a right turn. It changed its direction while still maintaining a negative acceleration.

Answer:

What is the difference between a comet and an asteroid?

Well, the difference between them is the composition which means what they're made of.

Asteroids are made of metals and rocky material.

Comets are made of Ice, dust, and again rocky material.

Answer:

Sound can be of different types—soft, loud, pleasant, unpleasant, musical, audible (can be heard), inaudible (cannot be heard), etc. Some sounds may fall into more than one category. For instance, the sound produced when an aeroplane takes off is both loud and unpleasant.

Answer:

Explanation:

When dealing with optics, there is an incident wave, a reflected wave, and a transmitted wave. An incident wave is the initial wave coming out from the source, like a flashlight.

Then the reflected wave is created when the incident wave encounters an interface like a piece of glass. The reflected wave will reflect like you would expect.

Then, the transmitted wave is the wave which passes through the interface and continues.

So, a good question would be to ask for the value of the reflected wave function given an initial incident wave.

Another example entirely would be to look at the reflected wave on a tensioned string. If you shake a string up and down, a wave will be sent through it. Once hitting the wall, the wave will reflect back. A good question there is asking how the amplitude of the wave changed.

moles of Xe:

[tex]= \frac{0.06}{131.293} \\\\ =0.00045699313 \ \mol[/tex]

moles of [tex]F_2[/tex]:

[tex]= \frac{0.0274}{38} \\\\= 0.00072105263\ \ mol[/tex]

moles of produced [tex]XeF_2:[/tex]

[tex]= 0.00024[/tex]

moles of left [tex]Xe[/tex]:

[tex]= 0.00021[/tex]

Calculate the Pressure:

[tex]= \frac{(0.08206\times 0.00024 \times 293)}{(.1)} + \frac{(0.08206\times 0.00021 \times 293)}{(.1)} \\\\= 0.10819611 \ \ atm \\\\ = 0.10819611 \times 760 \\\\ = 82.2 \ \ torr[/tex]

Answer:

[tex]\boxed {\tt 0.481481481 \ g/in^3}[/tex]

Explanation:

Density can be found by dividing the mass by the volume.

[tex]d=\frac{m}{v}[/tex]

The mass is 13 grams. Let's calculate the volume. This is a cube, so the volume formula is:

The volume is 27 cubic inches.

[tex]m= 13 \ g\\v= 27 \ in^3[/tex]

Substitute the values into the formula.

[tex]d=\frac{13 \ g}{27 \ in^3}[/tex]

Divide.

[tex]d=0.481481481 \ g/in^3[/tex]

The density is 0.481481481 grams per cubic inch.

Answer:

to go to get a bike

Explanation:

Option C is correct. The image is located between F and the center of the lens, on the other side of the lens the upright than the actual object.

Virtual and imaginary image is the type of upright image. A virtual picture is generated when light rays appear to meet at a certain spot following reflection from a mirror.

The picture that appears right-side-up is called an erect image. Unlike a virtual image, it is created by the real junction of light beams.

The lens in the illustration is a concave lens. The light rays that fall from the item onto the lens diverge, making it a diverging lens.

The item is held between the focus and the lens's center. At the same side of the item, an image would form between the focus and the lens's center.

The picture would be simulated, shrunk, and centered. As a result, the correct answer is: "The picture is upright."

Hence option C is correct

A spinning top (also called easily a top) is a specific toy that does not utilize the gyroscope effect during its movement.

The gyroscope effect refers to the characteristic that allows an object to maintain a constant direction of axis rotation when it is rotating.

This effect (gyroscope effect) mainly depends on the velocity of the object and its direction.

The gyroscope effect is exploited by many applications such as in missiles or satellites when they are in orbit.

The point on the x-axis where the magnetic field will be zero is  [tex] d =  2.8 \ cm [/tex]

b

The point on the x-axis where the magnetic field will be zero is [tex]Z =  5.333 \  cm [/tex]Explanation:

From the question we are told that

   The first  current is [tex]I_1 = 5.5 \ A[/tex]

    The point of x- axis  intersection is  [tex]x =  -2.0 \  cm[/tex]

    The second current is  [tex]I_2  =  2.5  \  A[/tex]

     The point of intersection of the x-axis is  [tex]x =  2 .0  \  cm[/tex]

Generally given that the current of the two wires are same direction it means that the magnetic field in -between the wires will cancel out  giving zero

 So  

       [tex]B_1 -  B_2 =  0[/tex]

=>     [tex]B_1  =  B_2 [/tex]

=>      [tex]\frac{\mu_o *  I_1 }{2 *  \pi *  d }  = \frac{\mu_o *  I_2 }{2 *  \pi *  (4 -d) }[/tex]

Here  d is the of one wire to the point where the magnetic field is 0

and  given that the total distance in-between the wire is  D  =  2 =  2 =  4

Hence the distance of the other wire to the point where magnetic field is zero is  (4 - d)

So

     [tex]\frac{5.5}{ d}  =  \frac{2.5}{4-d}[/tex]

=>   [tex] 8d  =  22 [/tex]

=>   [tex] d =  2.8 \ cm [/tex]

So the point on the x-axis where the magnetic field will be zero is  [tex] d =  2.8  [/tex]

 Generally given that the current of the two wires are opposition direction it means that the magnetic field at a position which is not in-between the wire will be zero  

Let that position be  k

Let  the distance from the middle of both wires to k  be Z  

So

      [tex]\frac{\mu_o *  I_1 }{2 *  \pi *  ( 2 +  Z) }  = \frac{\mu_o *  I_2 }{2 *  \pi *  (Z -2) }[/tex]

=>  [tex]5.5 Z  - 11 =  5+ 2.5 Z[/tex]

=>    [tex]3Z  =  16[/tex]

=>    [tex]Z =  5.333\  cm[/tex]

The angular momentum remains constant because there is a changing net torque acting on the system that averages to zero over time.

This principle states that If the external torque acting on a system is zero, then the angular momentum of the system is constant.

When the spheres-rod system is thrown straight upward and it rotates counterclockwise, the net torque acting on the system averages to zero over time.

Thus, we can conclude that, the angular momentum remains constant because there is a changing net torque acting on the system that averages to zero over time.

Answer: 28.71 km

Explanation:

For the convex mirror (ocean):

Radius of curvature = 6.4*10^3 km

Focal length (f) = R/2 = 3.2*10^3 km

Object distance (u) = -3.84*10^5

Mirror formula: [tex]\frac{1}{u} + \frac{1}{v} = \frac{1}{f}[/tex]

[tex]\frac{1}{u} + \frac{1}{v} = \frac{1}{f}[/tex]

[tex]\frac{-1}{3.84*10^5} + \frac{1}{v} = \frac{1}{3.2*10^3}[/tex]

v = 3173.55km

Magnification, [tex]m = \frac{-v}{u} = \frac{-3173.55}{-3.84*10^5} = \frac{h_{i} }{h_{o} }[/tex]

So, height of image/height of object = 3173.55/3.84*10^5

Diameter of image = 3173.55/3.84*10^5 * 3475

Diameter of image = 28.71 km

Therefore, the diameter of the image is 28.71 km
