Determine the magnitude of the force between two point charges, Q1 = -2e located at (-3.60 cm, +4.10 cm) and Q2 = -8e located at (-0.60 cm, -8.60 cm). Continue working the problem above by calculating the direction of the force that Q1 exerts on Q2. Give your answer in the form "abc.d" degrees, clockwise from the +x axis direction, and rounded to the nearest tenth of a degree.
An object is found to have a weight in air of 500N. It is then tied to a string connected to a balance and immersed in water (density of water is 1000 kg/m3). The scale now reads 450 N. at last the object is immersed in oil and is found to have a ..
what is the magnitude and direction of the force. explain the magnitude and direction of the force she exerts on you?
A ship's anchor weighs 5000 N. Its cable passes over a roller of negligible mass and is wound around a hollow cylindrical drum of mass 380kg and radius 1.10m. The drum is mounted on a frictionless axle. The anchor is released and drops 16 m to water.
A child on a boat throws a 5.40 kg package out horizontally with a speed of 12.0 m/s. determine the velocity of the boat immediately after, assuming it was initially at rest. The mass of the child is 26.5 kg and the mass of boat is 55.5 kg.
A small rocket to gather weather data is launched straight up. few seconds into the flight, its velocity is 110 and it is accelerating at 17 . At this instant, the rocket's mass is 50 and it is losing mass at the rate of 0.45 as it burns fuel.
