What is the force of gravity acting on a 490 kg spacecraft which has a circular orbit at a distance 2030 km from the surface of the earth? Data: Mass of the earth: 598 * 10^24
Radius of earth = 6.38*10^3
G=6.67*10^-11

B. At what speed is the satellite traveling around the Earth

The first law of thermodynamics states that heat added to a system is neither created nor destroyed but is transformed ⇒ as it changes into other forms of energy.

Very large accelerations can injure the body, especially if they last for a considerable length of time. one model used to gauge the likelihood of injury is the severity index ( ), defined as =/ . in the expression, is the duration of the accleration, but is not equal to the acceleration. rather, is a dimensionless constant that = the number of multiples of that the acceleration is equal to.in one set of studies of rear-end collisions, a person's velocity increases by 13.7 km/h with an acceleration of 36.0 m/s2 . let the + direction point in the direction the car is traveling. what is the severity index for the collision?

The heliocentric and the geocentric models of the solar system included these central principles
