Between 3000 and 2000.
The aortic valve allows the blood to leave the left ventricle.
Because it can and it's free.
Drinking the blood of the innocent.
I love cleaning the earth. I think it is the responsibility of everyone to leave the earth a better place. Each person can make a difference.
it's hot. ;)
The speed that a spacecraft must reach to leave Earth forever is 25,000 miles per hour. This is called "escape velocity", and this is the initial velocity required to leave the Earth behind completely. However, the concept of "escape velocity" is fundamentally flawed, being based on the concept of a shell being fired from a giant cannon. A rocket with enough fuel may leave the Earth behind at any speed desired. The required velocity to attain orbit depends on the altitude of the orbit; curiously, lower orbits require more speed, while higher orbits require less speed - but more fuel to get there! At the altitude of the ISS, an object must be going at about 18,000 MPH to be in a circular orbit.
Gravity is the force that allows satellites to orbit the Earth. The gravitational pull between the Earth and the satellite causes the satellite to continuously fall towards the Earth while moving forward at a speed that keeps it in orbit.
Earth travels around the sun at an average speed of about 67,000 miles per hour or 107,000 kilometers per hour. This fast speed allows Earth to complete one orbit around the sun in about 365.25 days.
Escape velocity from Earth is approximately 11.2 km/s, which is the speed a rocket needs to surpass Earth's gravitational force and leave its orbit.
The speed at which forward velocity carries an object into orbit (falling past the Earth's edge) is called "escape velocity". With no atmopheric friction or a counteracting acceleration, the object can coast in a stable orbit. The speed required, as measured at the Earth's surface, is 11.2 kilometers per second (7 miles/sec) or about 25,000 mph. That is the speed needed to leave Earth's atmosphere and go into space.
A space shuttle needs to reach a speed of approximately 17,500 miles per hour, known as orbital velocity, to successfully leave the Earth's atmosphere and enter space. This speed allows the shuttle to counteract the pull of Earth's gravity and achieve a stable orbit around the planet.
if you leave earth
No, a rocket leaving the moon's surface would not require as great a speed or force as one leaving the Earth's surface. This is because the moon has lower gravity than Earth, so the escape velocity required to overcome gravity and leave the moon is lower than that required to leave Earth.
The average speed of a space shuttle in Earth's orbit is approximately 17,500 miles per hour (28,000 kilometers per hour). This speed allows the shuttle to maintain its orbit around the Earth while traveling at a high velocity.
The International Space Station travels at an average speed of about 28,000 kilometers per hour (17,500 miles per hour) in low Earth orbit. This fast speed allows it to orbit the Earth roughly every 90 minutes.

A space station like the International Space Station (ISS) travels around the Earth at approximately 28,000 kilometers per hour (about 17,500 miles per hour). This high speed allows it to orbit the Earth about once every 90 minutes.
