Answer:

Pls mark brainlist... A graph showing Kepler's 3rd law. ... Kepler's 3rd law is a mathematical formula. It means that if you know the period of a planet's orbit (P = how long it takes the planet to go around the Sun), then you can determine that planet's distance from the Sun (a = the semimajor axis of the planet's orbit).

Explanation:

The square of the orbital period of a planet is proportional to the cube of the semi-major axis of its orbit” That's Kepler's third law. In other words, if you square the 'year' of each planet, and divide it by the cube of its distance to the Sun, you get the same number, for all planets

There are actually three, Kepler's laws that is, of planetary motion: 1) every planet's orbit is an ellipse with the Sun at a focus; 2) a line joining the Sun and a planet sweeps out equal areas in equal times; and 3) the square of a planet's orbital period is proportional to the cube of the semi-major axis of its ..

T=2π√r3GME. For an ellipse, recall that the semi-major axis is one-half the sum of the perihelion and the aphelion.

Answer:

option B

Explanation:

Radius of new planet,R' = 2R

Mass of the earth, M' = 2 M

R and M is the Radius and Mass of the earth.

Weight of the person on earth = 500 N

Weight of the person in the new planet = ?

We know acceleration due to gravity is calculated by using formula

$g = \dfrac{GM}{R^2}$

now, acceleration due to gravity on the new planet

$g' = \dfrac{GM'}{R'^2}$

$g' = \dfrac{G(2M)}{(2R)^2}$

$g' =\dfrac{1}{2} \dfrac{GM}{R^2}$

$g' =\dfrac{g}{2}$

here acceleration due to gravity is half in new planet, so weight will also be half on the new planet.

Weight on the new plane is equal to $\dfrac{500}{2}$ = 250 N

correct answer is option B

Determine the internal resistance of the capacitor.

11Alexandr11 [23.1K]

Answer:

The equivalent series resistance of a capacitor is the internal resistance that appears in series with the capacitance of the device. Almost all capacitors exhibit this property at varying degrees depending on the construction, dielectric materials, quality, and reliability of the capacitor.

If a characteristic of a parent, such as eye color,does not show up in offspring ,is it gone forever

mihalych1998 [28]

No it is not. It is still apart of the offspring's DNA. In fact it might show up in the very next generation!

1.A wave has a period of 20 seconds. What is the frequency?

Vesnalui [34]

1). Frequency = (1/period) = 1/(20sec) = (1/20) per sec .

2). Frequency= (3 waves) / (4 sec) = (3/4) (per sec)
Period = (1/freq) = 1/(3/4 per sec) = (4/3) sec

3). Speed= (freq) x (wavelength) (2 per sec) x (5 m) = (2 x 5) ( m per sec)
Speed doesn't depend on amplitude.
