A bicycle wheel makes 5000 revolutions in moving 11kmWhat is the radius of the wheel?
To find the radius of the wheel, we first calculate the circumference of the wheel using the formula: Circumference = 2 * π * radius. Since the wheel travels a distance of 11 km in 5000 revolutions, each revolution covers a distance of 11 km / 5000 = 0.0022 km. The circumference of the wheel is twice the distance covered in one revolution. Thus, we have Circumference = 2 * 0.0022 km = 0.0044 km. By setting up the equation 0.0044 km = 2 * π * radius, we can solve for the radius as 0.0044 km / (2 * π) ≈ 0.0007 km, or 0.7 meters.
In about 5 billion years at the end of its lifetime the Sun will end up as a white dwarf having about the same mass but reduced to about 15000 km in diameter What will be its density?
If the diameter is 15,000 km = 15,000,000 meters -> radius = 7,500,000 meters Volume -> 4*pi*r3/3 = 1.77×1021 m3 Mass of the Sun = 1.9891×1030 Density=M/V=1.9891×1030 / 1.77×1021 = 1,123,785,310.7 kg/m3
What is the maximum cell radius in LTE?
The maximum cell radius in LTE is approximately 100 km. However, this can vary based on factors such as terrain, frequency band used, and cell configuration.
What depth from surface of earth is value of acceleration due to gravity one fourth the value at the earth surface?
The force of gravity is proportional to the masses of the two objects and inversely proportional to the square of the distance between them. As a result, a gravity of one fourth that on the surface of the Earth would be observable at an altitude equal to the radius of the Earth, i.e. 6400 km. Note: This is up, in the air, not down, into the Earth. This distance is in outer space.In the other direction, the force of gravity gets smaller as one goes deeper into the earth. This is because the mass outside your current radius (as you descend) does not contribute. The mass inside your current radius is proportional to the cube of the radius. Gravity is proportional to this mass divided by the square of the radius. Therefore, gravity decreases linearly with the radius. So the acceleration of gravity is equal to one fourth its value at the earth's surface at one fourth of the earth's radius, or a depth of approximately 4800 km.
What radius of land was affected by nuclear fallout after the attack at Hiroshima?
The affected radius of land from nuclear fallout after the Hiroshima bombing was roughly 10 km (6.2 miles) from ground zero. This area suffered substantial damage and contamination from the blast and radiation.
How many earths could fit between earth and the sun?
The Earths Equatorial diameter is 12756 km, and there are (on average) 149,597,890 km to the sun, so we are talking about 11728 Earths.
How large is Mars and were is it located?
Mars is 6792 km in diameter at the equator, while the Earth is 12756 km in diameter at the equator. The Diameter of Mars is around 53% of Earths. Mars is the fourth planet from the sun, orbiting at a distance of 227,936,640 km (141,633,263 miles) from the sun on average.
How many times does the earth fit in the sun?
The Earths Equatorial diameter is 12756 km, and there are (on average) 149,597,890 km to the sun, so we are talking about 11728 Earths.
What planet has a diamiter of 12756 km?
The planet that has a diameter of approximately 12,756 km is Earth.
What is the radius and diameter of venus?
Radius = approx 6050 km, so diameter = 12100 km.
What is Europa's diameter compared to earth?
Europa: 1561 km radius Earth: 6371 km radius The diameter is twice the radius.
What is the diameter of Mercury compared to the earths diameter?
Mercury's diameter is about 3032 miles (4879 km), which is about three-eighths of Earth's diameter (about 38%).Earths volume is around 17.86 times that of Mercury's volume.Earth's radius is 2.61 times that of Mercury and 18.18 times the mass.
How many Mars equal one Earth?
It is difficult to quantify how many Mars planets equal one Earth due to the vast differences in size and composition between the two planets. However, it is estimated that it would take around 6.5 Mars planets to equal the mass of Earth.
What is the radius of a circle that has a diameter of 48 km?
radius = 48/2 = 24 km
What is Earth's diameter compared to Mars'?
The diameter of Mars is just over half the diameter of Earth.To be accurate, it depends on where you measure it.The equatorial radius of Mars is 3,396.2 km which is 0.533 Earth's 6,378.1 km.The polar radius of Mars is 3,376.2 km which is 0.531 Earth's 6,356.8 km.
A circle with a radius of 8 km?
Then it will have a diameter of 16 km
What approximate is the diameter of earths core?
Seismic data was used to estimate the radius of the Earths core. Inner = 1,221 km Outer = 2,259km Total = 3,480km Therefore an approximate diameter to the Earth core is 6,690 km or 4,325 miles. See related link for more information.
