The orbital period of a space shuttle in a 250 mile high orbit is approximately 91.3 minutes, and the orbital speed is approximately 17,500 miles per hour (7.68 kilometers per second).

This speed is determined by the gravitational pull from Earth, as well as the height of the orbit. The higher the orbit, the slower the orbital speed. For a 250 mile high orbit, the shuttle will need to maintain a constant speed in order to stay in orbit. The speed and orbital period of a space shuttle in orbit depend on a number of factors, including the height of the orbit, the mass of the shuttle, and the gravitational pull of the Earth.

The pressure of the gas in a container with a volume of 1.54 L is initially evacuated. Then it is filled with 0.221 g of N2 is 1619Pa.

A gas with a small density and at a sufficiently high temperature so that the interaction between its particles can be neglected can be considered an ideal gas. In this case, the pressure, volume, and temperature of the gas are related as follows:

PV=mMRT, where m is the mass of the gas and M is the molar mass of the gas. The pressure of the gas can be found using the ideal gas law:p =mRT/MV.

The temperature of the gas can be found from the RMS speed of the molecules of nitrogen, which is given by: vrms=√3RT/M. Solving for the temperature, we obtain: T= Mv² / 3 R. And pressure is P= mv² /3V. So P=[ 0.221×(184)²]/ 3×1.54 = 1619 Pa.

[tex]1.602 x 10^-17[/tex] is the work must we do on an electron to move it from point A, , to point B, that is at a potential of -50V, along the semicircular path.

In order to move the electron from point A to point B, we need to do work on it to overcome the electric potential difference between the two points. Since the two points have potentials of +50V and -50V respectively, the total potential difference is 100V.

Since the electric field is conservative, the work done by it depends only on the potential difference between points A and B and not on the path taken. The potential difference between points A and B is given by:

ΔV = V_B - V_A = -50 V - (+50 V) = -100 V

To move an electron from point A to point B, we need to do work on it equal to the change in its potential energy. The potential energy of an electron in an electric field is given by:

U = qΔV

where q is the charge of the electron, and ΔV is the potential difference.

The charge of an electron is:

q = -1.6 x [tex]10^{-19 }[/tex]C

Substituting the values, we get:

U = (-1.6 x [tex]10^{-19 }[/tex] C) x (-100 V)

U = 1.6 x [tex]10^{-19 }[/tex]

Therefore, we need to do work on the electron equal to 1.6 x 10^-17 J to move it from point A to point B along the given semicircular path.

The acceleration is expressed as the product of the change in time and the change in velocity, and it is 2.3 m/s. 34.78 seconds pass before the wheels lift off the ground.

Speed is the rate at which an object travels along a path over time, whereas velocity is the speed and direction of an item's motion.

Taking the first interval, we find

a = Δvx/Δt

a = 23m/s/10m/s

a = 2.3m/s

By dividing the acceleration in m/s2 by the value of g, or the acceleration of gravity (9.81 m/s2), we may determine the jet's acceleration in g's.

ag = a/g

2.3/9,8

ag = 0.33g

When the jet reaches its takeoff velocity, which is 80 m/s, the wheels come off the ground.

The jet's velocity is zero at time t=0 s. Since we are aware that the acceleration is constant (a=2.3 m/s2), we can use the equation to determine the time t at which the jet achieves a velocity of vf=80 m/s.

vf = vi + at

angular velocity after 12.0 s = 4.50 rad/s - (0.822 rad/s^2 * 12.0s)

angular velocity after 12.0 s = 2.052 rad/s

What is angular velocity?

Angular velocity is a measure of the angular displacement over time of a rotating object. It is expressed as the rate of change of angular displacement with respect to time, and is usually expressed in radians per second or revolutions per minute. Angular velocity is considered to be a vector quantity, meaning it has magnitude and direction. It is also a measure of the speed at which an object is rotating. When an object is rotating in a circular motion, its angular velocity is the same as its tangential velocity. Angular velocity can also be used to calculate the linear velocity of an object, by multiplying its angular velocity by the radius of its circular path.

The total rotational kinetic energy of the system can be found by evaluating the above expression using the given values of m, r, and ω [tex]KE = 1/2 * (m1 * r1^2 + m2 * r2^2 + m3 * r3^2) * (2.00 rad/s)^2[/tex]

The total rotational kinetic energy of a system can be found by evaluating the expression 1/2 Iω^2, where I is the moment of inertia of the system and ω is its angular velocity. In this case, the moment of inertia of the system can be found by adding the moments of inertia of each particle and the connecting rods.

Since the rods have negligible mass, their moment of inertia is also negligible and can be ignored. The moment of inertia of each particle is given by the formula:

I = mr^2

where m is the mass of the particle and r is its distance from the axis of rotation.

Assuming the particles have masses m1, m2, and m3 and distances from the axis of rotation r1, r2, and r3, respectively, the total moment of inertia is:

[tex]I = m1 * r1^2 + m2 * r2^2 + m3 * r3^2[/tex]

Substituting the given values, we find:

I = (m1 * r1^2 + m2 * r2^2 + m3 * r3^2)

Finally, substituting the moment of inertia and angular velocity into the expression for rotational kinetic energy, we find:

KE = 1/2 * I * ω^2

[tex]KE = 1/2 * (m1 * r1^2 + m2 * r2^2 + m3 * r3^2) * (2.00 rad/s)^2[/tex]

The rate at which velocity changes is called acceleration. Acceleration typically indicates a change in speed, but not necessarily. An item that follows a circular course while maintaining a constant speed is still moving forward because the direction of its motion is shifting.

The motion of an item is related to the forces operating on it by Newton's equations of motion. According to the first law, until a force acts on an item, it will not alter its motion.
