A ballet director assigns slow, graceful steps to larger dancers, and quick movements to smaller dancers. Why is this plan successful?

At some distance away from a long, straight current carrying wire, the magnetic field points perpendicular to the wire. This is known as the right-hand rule, which is used to determine the direction of the magnetic field in relation to the direction of the current flow.

A long, straight current-carrying wire produces a magnetic field, and the direction of the field is determined by the right-hand rule. This rule states that if you wrap your right hand around the wire in such a way that your thumb points in the direction of the current, your fingers will point in the direction of the magnetic field.

The direction of the magnetic field can also be determined by the direction of the current flow. The field is perpendicular to the wire and circular around the wire. This means that the field lines of the magnetic field are circular around the wire, and they point in the direction of the current flow.

However, if aliens were to increase the rotational speed of the space station, it would have a dramatic effect on the people inside.  They would experience a decrease in their apparent weight, which could cause problems with movement and coordination. In addition, the increased centrifugal force could put a strain on the structure of the space station, potentially causing damage or even catastrophic failure.

If aliens came and caused the rotational speed of a large rotating space station to increase, the apparent weight of the people would decrease.

This is because the apparent weight of a person is determined by the force exerted on them by the surface they are standing on, which is usually the ground.

In a large rotating space station, the apparent weight of a person is caused by the centrifugal force they experience due to the rotation of the station.

As the speed of the rotation increases, so does the centrifugal force.

This means that the apparent weight of the people inside the station would decrease.

The idea of living inside a large rotating space station has been explored in science fiction for many years, but it is also a concept that scientists have studied as a potential way to simulate gravity in space.

By rotating a large space station, it is possible to create artificial gravity that could be used to keep astronauts healthy on long-duration missions.

Overall, while the concept of living inside a large rotating space station is an intriguing one, it is important to remember that it would require careful engineering and design to ensure the safety and well-being of the people inside.

The streamlines equations are \(x^2 - y^2 = c_1\) and \(xy = c_2\), where \(c_1\) and \(c_2\) are constants.

The velocity field is given by,

\(V_x = x (x^2 + y^2)^-^1^/^2\)

\(V_y = y (x^2+ y^2)^-^1^/^2\)

Now, we know that the tangent to a streamline is always parallel to the velocity vector. Hence, for the streamline equations, we must have

\(dx/dy = V_x/V_y\)

Therefore,\((x/y) = V_x/V_y = x/y\)

⇒ \(x^2 - y^2 = c_1\)

or, \((x+y)(x-y) = c_1\)

Hence, the equation of the streamlines are given by \(x^2 - y^2 = c_1\)

Now, for the other streamline equation, let's differentiate both sides of \(V_x\)= constant along the streamline:

\(dx/ds = constant/y\)

And differentiate both sides of \(V_y\) = constant along the streamline:

\(dy/ds = constant/x\)

Multiplying both equations, we get

\(xdx/ds = ydy/ds\)

or,\(xdx = ydy\)

Integrating, we get

\(x^2/2 = y^2/2 + c_2\)

or,\(xy = c_2\)

Thus, the equations of the streamlines are \(x^2 - y^2 = c_1\) and \(xy = c_2\)

S-waves, also known as shear waves, flow through liquids but not solids, which is correct information regarding seismic waves travelling through the earth.

Seismic waves are created when materials unexpectedly move inside the Earth, such as when they slide down a fault when in an earthquake.. Seismic waves can also be produced by volcanic eruptions, explosions, landslide, avalanches, or even swiftly flowing rivers. An acoustic wave that passes through the Planet or the other planetary body is called a seismic wave. Large landslides, volcanic eruptions, magma movement, earthquakes, and man-made explosions that release a lot of low-frequency acoustic energy can all cause it.

Sudden movement along Earth's fault lines causes earthquakes. The motion releases "elastic strain" energy that has been accumulated inside the form of seismic waves, that travel through the Earth & cause the earth to tremble. Seismic wave research is crucial for understanding and forecasting earthquakes and tsunamis, but it also provides details on the structure and properties of the Earth, much like it did for the discovery the Mohorovicic's discontinuity.

To calculate the capacitance needed to produce a resonant frequency of 1.00 GHz with an 8.00 nH inductor, we can use the formula, So, you would need a capacitance of approximately 2.53 pF to produce a resonant frequency of 1.00 GHz using an 8.00 nH inductor.

resonant frequency = 1 / (2π√(inductance * capacitance))
Rearranging the formula to solve for capacitance, we get:
capacitance = 1 / (4π² * inductance * resonant frequency²)
Plugging in the values given, we get:

capacitance = 1 / (4π² * 8.00 nH * (1.00 GHz)²)
capacitance = 4.97 pF
Therefore, to produce a resonant frequency of 1.00 GHz with an 8.00 nH inductor, we need a capacitance of 4.97 pF.
To find the capacitance needed to produce a resonant frequency of 1.00 GHz using an 8.00 nH inductor, you can use the formula for resonant frequency in an LC circuit:

f = 1 / (2 * π * √(L * C))
Where f is the resonant frequency, L is the inductance, and C is the capacitance.
First, convert the resonant frequency to Hz: 1.00 GHz = 1,000,000,000 Hz.
Next, rearrange the formula to solve for capacitance:
C = 1 / (4 * π^2 * L * f^2)
Now, plug in the values:
C = 1 / (4 * π^2 * 8.00 x 10^-9 H * (1,000,000,000 Hz)^2)
C ≈ 2.53 x 10^-12 F\
Finally, convert the capacitance to pF:
C ≈ 2.53 pF

The force acting on the sports car is the product of its mass and acceleration. The force on the car is 3300 N.

Force is an external agent acting on a body to deform it or to change it from the state of rest or motion. There are different kinds of forces such as frictional force, gravitational force, nuclear force, magnetic force etc.

Frictional force is acting as a hindrance to the motion of an object. The frictional force is the product of normal force and coefficient of friction.

According to second law of motion, force is the product of mass and acceleration.

Given mass m = 1000 Kg

The ratio of r 2/r 1 of their resistances is 4.

So, the correct answer is E.

Let the resistivity of wire 1 be r 1, and resistivity of wire 2 be r 2. Let the length and diameter of wire 1 be l and d respectively.

Thus, length and diameter of wire 2 will be 2l and 2d respectively.

Thus, r ∝ (l/A).

The cross-sectional area of wire 1 is πd²/4.The cross-sectional area of wire 2 is π(2d)²/4 = πd².

Since r ∝ (l/A), we have:

r 1/r 2 = (l1/d²)/(l2/d²) = (l1/l2) = 1/2

Thus, the ratio of the resistances is:

r 2/r 1 = r 2/r 1 = 2/(1/2) = 4.
