What is the relationship between the distance from the Sun and the orbital period?

P^3=a^2
P^2=Gm
P^2=a^3
T^2=P^3

Answers

Answer 1

Answer:

Kepler's third law - shows the relationship between the period of an objects orbit and the average distance that it is from the thing it orbits. This can be used (in its general form) for anything naturally orbiting around any other thing.

Formula: P2=ka3 where:

P = period of the orbit, measured in units of time

a = average distance of the object, measured in units of distance

k = constant, which has various values depending upon what the situation is, who P and a are measured.

This is the general form of the formula, so obviously you need at least two of the quantities to find the third. "k" is the trickiest thing since it depends upon the objects that are involved and how you measure "P" and "a". Since "P" can be measured in any unit of time (seconds, days, years, etc), and "a" can be measured in any unit of distance (meters, km, AU), the value of "k" can be quite diverse from one system to another.

There is a simplified version of this law: P2 = a3 where:

The object must be orbiting the Sun

P = period of the orbit in years

a = average distance of the object from the Sun in AU

This version is much more simple, since it has "k" = 1, so it is ignored when those units of measure are used.

an experimental plane, currently overhead, is flying at 120 mph at an altitude of 32 thousand feet. how fast is the plane’s distance from you increasing at the moment when the plane is flying over a point on the ground 24 thousand feet from you?

Answers

This question involves the concepts of Pythagora's Theorem and derivatives.

The plane's distance is increasing at a rate of "105.6 ft/" (OR) "72 mph".

First, we will write an expression for the distance between the person and the plane in terms of time. For that purpose, we will use Pythagora's Theorem. Here, the altitude will act as perpendicular, the horizontal distance on the ground will be the base, and the straight line distance between the plane and the person will be the hypotenuse.

[tex]Hyp^2 = Base^2+Perp^2\\s^2 = (vt)^2+(32000\ ft)^2\\s=\sqrt{(vt)^2+(32000)^2}[/tex]

where,

s = plane's distance from the person

v = horizontal speedof the plane = [tex](120\ mph)(\frac{1.47\ ft/s}{1\ mph})[/tex] = 176 ft/s

t = time

Therefore,

[tex]s=\sqrt{(176t)^2+(32000)^2}[/tex]

Taking the derivative with respect to time:

[tex]\\\\\frac{ds}{dt} = \frac{1}{2}\frac{(2t)(176)^2}{\sqrt{(176t)^2+(32000)^2}}\\\\\frac{ds}{dt} = \frac{61952\ t}{2s}[/tex]

where,

[tex]\frac{ds}{dt}[/tex] = rate at which plane's distance is increasing from the person = ?

s = distance = [tex]\sqrt{(24000\ ft)^2+(32000\ ft)^2} = 40000\ ft[/tex]

t = time = [tex]\frac{horizontal\ distance}{v} = \frac{24000\ ft}{176\ ft/s} = 136.36\ s[/tex]

Substituting these values in the equation, we get:

[tex]\frac{ds}{dt}=\frac{(61952)(136.36)}{(2)(40000)}[/tex]

[tex]\frac{ds}{dt}=105.6\ ft/s = 72\ mph[/tex]

Answers

From the graph, the segments that move the greatest distance are AB and DE.

We have,

From the graph,

The y-axis is the speed.

The x-axis is the time.

This means,

Speed = Distance / Time

So,

The horizontal line is the distance.

Now,

There are 5 points: A, B, C, D, and E.

There are four parts:

AB, BC, CD, and DE.

On the graph.

So,

I part = 1/3 = 0.33

The distance covered in each part is:

AB = 2 parts = 2 x 0.33 = 0.66

BC = 1 part = 0.33

CD = 1 part = 0.33

DE = 2 parts = 2 x 0.33 = 0.66

Thus,

The segments that move the greatest distance are AB and DE.

a 3000 kg car with a full load of people, has a kinetic energy of 190,000 J. What would the kinetic energy of the car be if it was moving at the same speed but a different mass of 1500 kg?

Answers

Answer:  15.9 m/s

Explanation:

KE = 1/2(mv^2)

190,000J = 1/2(3000kg)*v^2

1 J = 1 kg*m^2/s^2

190,000 kg*m^2/s^2 = 1/2(3000kg)*v^2

v^2 = (190,000 kg*m^2/s^2)/(1/2(3000kg))

v^2 = (190,000 kg*m^2/s^2)/(1500kg))

v^2 = 126.6667 m^2/s^2

v = 11.25 mm/s velocity of 3000kg vehicle

With the same kinetic energy, a vehicle of 1500kg would have a different velocity:

190,000 kg*m^2/s^2 = 1/2(1500kg)*v^2

190,000 kg*m^2/s^2 =(750kg)*v^2

v^2 = 253.33 m^2/s^2

v = 15.9 m/s

Helicopter rescue winch-men must dangle a metal wire below them so that it always touches the ground or water surface first. This discharges static electricity that may have built upon the helicopter.

What is static electricity?

Static electricity is a familiar electric phenomenon in which charged particles are transferred from one body to another. For example, if two objects are rubbed together, especially if the objects are insulators and the surrounding air is dry, the objects acquire equal and opposite charges.

What is static electricity caused by?

Static electricity is generated by friction between two insulating materials. When the materials are rubbed together, electrons are removed from atoms within the materials, giving rise to a static electric charge.

Two astronauts are playing catch in a zero gravitational field. Astronaut 1 of mass m1 is initially moving to the right with speed v1 . Astronaut 2 of mass m2 is initially moving to the right with speed v2>v1 . Astronaut 1 throws a ball of mass m with speed u relative to herself in a direction opposite to her motion. Astronaut 2 catches the ball. The final speed of astronaut 1 is vf,1 and the final speed of astronaut 2 is vf,2 .What is the speed vf,1 of astronaut 1 after throwing the ball?

Answers

The final velocity ([tex]v_1_f[/tex]) of the first astronaut will be greater than the final velocity of the second astronaut ([tex]v_2_f[/tex]) to ensure that the total initial momentum of both astronauts is equal to the total final momentum of both astronauts after throwing the ball.

The given parameters;

Mass of the first astronaut, = m₁Mass of the second astronaut, = m₂Initial velocity of the first astronaut, = v₁Initial velocity of the second astronaut, = v₂ > v₁Mass of the ball, = mSpeed of the ball, = uFinal velocity of the first astronaut, = [tex]v_f_1[/tex]Final velocity of the second astronaut, = [tex]v_f_2[/tex]

The final velocity of the first astronaut relative to the second astronaut after throwing the ball is determined by applying the principle of conservation of linear momentum.

[tex]m_1v_1 + m_2v_2 = m_2v_2_f + m_1v_1_f[/tex]

if v₂ > v₁, then [tex]v_1_f > v_2_f[/tex], to conserve the linear momentum.

Thus, the final velocity ([tex]v_1_f[/tex]) of the first astronaut will be greater than the final velocity of the second astronaut ([tex]v_2_f[/tex]) to ensure that the total initial momentum of both astronauts is equal to the total final momentum of both astronauts after throwing the ball.
