When the distance between earth and sun is halved the duration of year will become?

This is known as the Kepler’s third Law of Planetary motion. Therefore, the new duration of year will be 2.82 times the original year i.e. 1032 days per year.

When the distance between the earth and the sun becomes half of its present value then calculate the number of days in a year?

(T1T2)2=(r1r2)3=[r112r1]3=8⇒T1T2=2√2∴T2=T12√2=365 days2√2=129 days.

When the distance between the Sun and the earth is minimum then the earth is said to be in?

Complete answer: The day is on 3rd or 4th January, it is called the perihelion. That day, the gap between earth and sun was about 148 km aside.

What is equal to the distance between the earth and the sun?

astronomical unit (AU, or au), a unit of length effectively equal to the average, or mean, distance between Earth and the Sun, defined as 149,597,870.7 km (92,955,807.3 miles).

Would be the duration of the year if the distance between the Earth and the Sun gets doubled?

According to Kepler’s Third Law, the square of a planet’s orbital period P is proportional to the cube of the orbit’s semi-major axis a, such that P2∝a3. P2 = 2.828 years. If you double the distance of Earth from the Sun, it will take Earth in the new location 2.828 years to complete one revolution.

What would happen if the distance between Earth and sun reduces to half?

If the distance between the Sun and the Earth reduces to half, what will be its effect on Earth? There will be no seasons. There will be a rise in temperature in summer as well as in winter.

What would be the possible length of the year if the distance between a planet and the sun gets doubled?

So, doubling the distance reduces the force by a factor of 4. Kepler’s third law relates the semi-major axis distance a in AU(Astronomical Units) to the orbital period P in years. This would make the orbital period P=2.828 years.

In which month the distance between Earth and sun is smallest?

January
Explanation : In January Earth makes its closest approach to the Sun for the year.

What will happen to the centripetal force if the distance between the planet and the sun is half?

By definition, period P is the time for one complete orbit. Now the average speed v is the circumference divided by the period—that is, v=2πrP v = 2 π r P . GMr=4πr2P2 G M r = 4 π r 2 P 2 .

How many days in a year if the distance from the Sun?

Let T1 and R1 be original time period and radius of revolutions of Earth’s orbit around Sun and T2 and R2 be the time period and radius after the distance between Sun and Earth is halved. Therefore if the distance between the earth and the sun were half its present value, the number of days in a year would have been 129 days

What would be the number of days in a year?

T2 and R2 be the time period and radius after the distance between Sun and Earth is halved. Therefore if the distance between the earth and the sun were half its present value, the number of days in a year would have been 129 days Answered by Shiwani Sawant | 5th Jun, 2020, 03:58: PM

What would happen if the distance between Earth and Sun were reduced?

If the distance between earth and sun were reduced to half of its present value, then the number… If the distance between earth and sun were reduced to half of its present value, then the number of days in one year would have been: 1. Planets revolve in elliptic orbits around the sum. 2.

What is the square root of time period around the Sun?

Square of time period of motion of a planet around sun is proportional to the cube of distance (radius/major axis) of the orbit i.e. T ∝ a3 2 T ∝ a 3 2 Become a Study.com member to unlock this answer!
