How Many Significant Digits are in 0.0217

A). calculate the trajectory neglecting the force due to aerodynamic drag. (same as matlab assignment 1) b). calculate the trajectory using a constant drag coefficient of cd = 0.5. c).

What two forces keep the planets of our solar system in orbit around the sun

Some runners train with parachutes that trail behind them to provide a large drag force. These parachutes are designed to have a large drag coefficient. One model expands to a square 1.8 m on a side, with a drag coefficient of 1.4.

An astronaut on the planet Trappist-1b tosses a rock horizontally with a speed of 7.95m/s. The rock falls through a vertical distance of 2.35m and lands horizontal distance of 9.57m from the astronaut.

A student holds a magnet 1 m from a paper clip and sees no evidence of a force acting between the two. When the student brings the magnet 1 cm away from the paper clip, the paper clip begins to slide toward the magnet.

According to Newton's 3rd Law, an object's momentum depends on it's velocity and mass. 4 dog-sled teams competed to see who could gain the greatest momentum.

When resistors are connecting in a series, does the position of ammeter make any difference?
