How does the length of days change if radius of earth is doubled?
Answer: Length of day will also be doubled ie. 48 hours…
What would happen if the earth is doubled in size?
If Earth’s diameter were doubled to about 16,000 miles, the planet’s mass would increase eight times, and the force of gravity on the planet would be twice as strong. Life would be: Built and proportioned differently.
What will be the duration of the day and night in hour if the diameter of the Earth is suddenly reduced to half?
Length of the day would become 6 hours.
What is duration Day?
a. Also called mean solar day. a division of time equal to 24 hours and representing the average length of the period during which the earth makes one rotation on its axis.
What will be the duration of the day if the earth suddenly?
If the volume of earth suddenly shrinks to 1/64th of its original volume then the radius of the earth will decrease to 1/4th of its original radius. So, duration of the day will be 1.5 hrs.
What will be the duration of the Day of the Earth suddenly shrinks to 1 27?
Earth would spin 9 times faster, so our day would be only 2.66 hours long.
How does the length of day affect the size of Earth shrinks?
∴ On shrinking the earth the moment of inertia will decrease, ∴ Time duration of day will decrease as I∝T.
What will happen if Earth shrinks?
If the earth were to shrink from its original size than the moment of inertia will decrease. By the conservation of angular momentum, the angular velocity will increase to to its small size and thus the length of the day will decrease.
What would happen to the graph of the earth shrinks to half of its radius?
Answer. m1 is the mass of the Earth and m2 to be the mass of the body. If mass is kept constant and G being universal gravity constant, radius is halved, then as radius decreases acceleration due to gravity increases, the new acceleration due to gravity becomes 4 times g or 4g. Weight is calculated as a Force.
What happens if Earth’s radius is halved?
It is all solved above. Only , the weight of the body becomes four (4)times the initial weight when the radius of the earth is halved and its mass is kept constant due to the increase in acceleration due to gravity (g) of the earth.
Where do you weight the most on the earth?
Jupiter is the largest planet in our Solar System with the most mass. Because of Jupiter’s mass, you would weigh more on that planet than on any other one in our Solar System. If you weighed 68 kg on Earth then you would weigh 160.7 kg on Jupiter, over twice your normal weight.
What would happen to your weight if the Earth’s radius doubled?
Doubling the mass of the Earth would double your weight, since gravitational force is directly proportional to mass, but doubling the radius (which doubles if the diameter doubles) would decrease your weight by a factor of 1/4, since gravitational force is inversely proportional to the square of the radius.
How does the duration of day changes if radius of earth reduces to half its original radius keeping the mass constant?
So, for an Earth that is contracted to half its present size with mass constant, the duration of a day will be just 6hrs.
Does moment of inertia depend on angular velocity?
A. Angular velocity of the body. Hint: Moment of inertia of a body is defined as the quantity which is expressed by the body resisting the angular acceleration which is given as the product of the mass of every particle with its square of the distance from the axis of the rotation. …
What happens to the duration of the day if Earth suddenly contracts mass remaining constant?
Mass remaining constant, if the earth suddenly contracts to one third of its present radius, the length of the day would be shorted by. Step by step solution by experts to help you in doubt clearance & scoring excellent marks in exams.
What is the radius of the earth?
6,371 km
Who calculated Earth radius?
Eratosthenes
