How deep would you have to drill to reach the center of earth?

1 answer:

4 0

The radius of the Earth is about 3,960 miles.

That's how far the center of the Earth is straight down under your feet.
It's farther than the distance all the way across the USA, from New York
to Los Angeles. It's like the distance from London (England) to Chicago.

If you drill absolutely straight and aim straight down, that's how far
you need to drill to reach the center. Unfortunately, your drill will melt
long before you get there.

The longest hole ever drilled into the Earth (so far) is the Sakhalin-I Oduptu Well,
drilled by Russia into the sea-bottom in 2011.

That hole is 40,502 feet ... roughly 7.67 miles, or about 0.0019 of the distance
to the center of the Earth. You can see that we still have quite a long way to go !

Yanka [14]

Answer:

Every object in the universe that has mass exerts a gravitational pull, or force, on every other mass. The size of the pull depends on the masses of the objects. You exert a gravitational force on the people around you, but that force isn't very strong, since people aren't very massive.

A certain fuel-efficient hybrid car gets gasoline mileage of 55.0 mpg (miles per gallon). (a) If you are driving this car in Eur

ololo11 [35]

We will start by defining the units and their respective equivalences between the proposed measurement systems

$1km = 0.6214mi$

$1gallon = 3.788 litres$

PART A ) The mileage of the car is 55mpg (Miles per gallon)

$55mpg = 55(\frac{miles}{gallon}) (\frac{1km}{0.6214miles})(\frac{1gallon}{3.788L})$

$55mpg = 23.4km/L$

Therefore the mileage of the car is 23.4km/L

PART B ) The mileage of the car means that the car travels 23.4km and consumes 1 liter of fuel. Then

$1L = 23.4km$

For the car to travel 1500km the amount of fuel would be,

$1500km= (1500km)(\frac{1L}{23.4km})$

$1500km = 64.1L$

But 1 gas tank can only hold 45Liters of fuel, then the number of tank required would be

$\text{Number of tanks required} = \frac{64.1L}{45L}$

$\text{Number of tanks required} = 1.4tanks$

Thus the number of tanks of gas required to drive 1500km is 1.4

If we have a new moon today, when we will have the next full moon?.

Sav [38]

29.5 days

It takes 27 days, 7 hours, and 43 minutes for our Moon to complete one full orbit around Earth. This is called the sidereal month, and is measured by our Moon's position relative to distant “fixed” stars. However, it takes our Moon about 29.5 days to complete one cycle of phases (from new Moon to new Moon).
