<span>to plot and time the positions of comets and asteroids as they orbit the The application to Kepler's law are:
1. Sunplotting a course out of the solar system to explore other planets similar to Earth
2. plot the orbit of moons or man-made space satellites
</span><span>
An example of this is Kepler’s harmonic law is the third law of the Planetary Motion. He discovered this after ten years that there is a relation between the time of a planet’s orbit and its distance from the sun. The harmonic law states that the squares of the orbital periods of the planets around the Sun are proportional to the cubes of the planet’s orbital period</span>

Answer:

A. To plot and time the positions of comets and asteroids

Explanation:

Kepler's law helps to understand the orbits of many planets and celestial bodies including comets and asteroids.

It was found that like other bodies or planets, comets also revolve around the sun in an elliptical path.

Consider sun is situated at one foci, when comets revolve around the sun the distance is very large but as soon as it comes closer to sun, it starts to melt thus forming a comet tail.

Hence time and position of a comet is described by Kepler's law.

Answer:

1) D, 2) D, 3) B, 4) B, 5) C

Explanation:

You are asked to select the correct answer

1) The conservation of energy is one of the most important principles of physics that allows solving countless problems in life.

the correct answer is D

2) when a body falls, the gravitational potential energy is transformed into kinetic energy and both are transformed into thermal energy

the correct answer is D

3) When the gravitational potential energy is maximum, the kinetic energy is minimum and when the kinetic energy is maximum, the gravitational energy is minimum.

Correct answer B

4) speed is defined by

v = x / t

so the correct answer is B in the SI system

5) when we repeat a measurement several times, the random or statistical errors decrease, therefore the confidence of the measurement increases.

The correct answer is C

How could you increase the sleds acceleration

gladu [14]

By putting this special transportation plastic on the bottom of the sled, because the transportation plastic is slick. that is what the transport bins slide around on. (p.s) the plastic is really expensive!

A weather balloon is inflated to a volume of 26.8 LL at a pressure of 744 mmHgmmHg and a temperature of 31.2 ∘C∘C. The balloon r

elena-s [515]

Answer:

43.96 L

Explanation:

We are given that

$V_1=26.8 L$

$P_1=744mm Hg$

$T_1=31.2^{\circ} C=31.2+273=304.2K$

$P_2=385mmHg$

$T_2=-14.8^{\circ}=273-14.8=258.2K$

We know that

$\frac{P_1V_1}{T_1}=\frac{P_2V_2}{T_2}$

$V_2=\frac{P_1V_1T_2}{P_2T_1}$

Substitute the values

$V_2=\frac{744\times 26.8\times 258.2}{385\times 304.2}$

$V_2=43.96 L$

Hence, the volume of balloon at -14.8 degree Celsius=43.96 L

A race car starting from rest accelerates uniformly at a rate of 3.90 m/s^2 what is the cars speed after it has traveled 200 m.

snow_tiger [21]

The formula for accelerational displacement is at^2/2, so we know that 3.9t^2/2 = 200, or 3.9t^2 = 400. t = $\sqrt{400/3.9} \approx 10.12739367$ , at = v, so $3.9 * 10.12739367 \approx 39.5 m/s$
