In 1610 Galileo was the first person to observe with aid of the telescope these four moons orbiting Jupiter. Explain why Galileo's observation of this motion did not support the geocentric model of our solar system.

The image shows the positions of a car on a roller coaster track. arrange the cars in order based on their gravitational potential energy. begin with the lowest potential energy and end with the highest.

How to tell if a molecule is polar or nonpolar with electronegativity

The scalar triple product computes the magnitude m of the moment of a force vector f about a specified line. it is m = (r × f) · n, where r is the position vector from the line to the point of application of the force and n is a unit vector in the direction of the line. use matlab to compute the magnitude m for the case where f = [12, −5, 4] n, r = [−3, 5, 2] m, and n = [6, 5, −7].
