What is the diameter of the sun in scientific notation?

For example, the diameter of the sun is approximately one million, three hundred ninety thousand kilometers, or 1,390,000 km. To make these large numbers easier to write, astronomers and other scientists use scientific notation. In scientific notation, the diameter of the sun is: 1.39 x 106 km Page 2 a.

Is radius a diameter or r?

A chord passing through the center of a circle is known as the diameter of the circle and it is the largest chord of the circle. This diameter is twice that of the radius of a circle i.e. D=2r, where ‘D’ is the diameter and ‘r’ is the radius.

What is 0.000000456 in scientific notation?

For example, starting with 1,230,000, move the decimal point six places to the left yielding 1.23, and multiply by 106, to give the result1.23×106. Similarly, starting with 0.000000456, move the decimal point seven places to the right yielding 4.56, and multiply by 10−7, to give the result4.56×10−7.

How do you write 384000000 in standard form?

Solution:- The standard form of the number 384,000,000 = 3.84 × 108 m. (b) Speed of light in vacuum is 300,000,000 m/s.

How far is the moon from Earth in meters scientific notation?

$384000\ km=3.84\times {{10}^{8}}m$. Thus, the value of distance between the Earth and the moon can be given in meters in exponential form as $3.84\times {{10}^{8}}m$ .

How far away was the Moon 1 billion years ago?

At the time of formation it was about 4 Earth-radii distant—that is, it was orbiting about 15,000–20,000 miles away, as opposed to the current average distance of 238,000 miles. (The numbers are approximate because they are based on models that contain a lot of uncertainties.)

How far away was the Moon 2 billion years ago?

We then used this precession signal to calculate the distance between the Earth and the moon 2.46 billion years ago (opens in new tab). We found that the moon was around 37,280 miles (60,000 kilometres) closer to the Earth then (that distance is about 1.5 times the circumference of Earth).

Is the Moon 60 miles away?

The Short Answer: The Moon is an average of 238,855 miles away from Earth, which is about 30 Earths away.

Is the Moon 25 miles away?

The Short Answer: The Moon is an average of 238,855 miles away from Earth, which is about 30 Earths away.

What is radius of moon Class 9?

The mass of the moon is 7.35×1022kg. The radius of the moon is 1.74×106 m.

What is moon radius in km?

Size and Distance With a radius of about 1,080 miles (1,740 kilometers), the Moon is less than a third of the width of Earth. If Earth were the size of a nickel, the Moon would be about as big as a coffee bean. The Moon is an average of 238,855 miles (384,400 kilometers) away.

Can a human walk around the Moon?

A 2014 NASA study looked at the theoretical maximum walking speed on the Moon, finding that you could walk at 5km/h before you would need to break into a loping run. At this speed, you would travel the 10,900km circumference of the Moon in 91 days of non-stop walking.
