Suppose in a situation like m1 = 200g were at the 20-cm position and m2 = 100g at the 65-cm position. Would there be a problem in experimentally balancing an equilibrium system with m3 = 50g? Explain. If so, how might the problem be resolved?
A container of hot water at 80 degrees cools to 79 degrees in 15 seconds while it is placed in a room that is t 20 degrees. Use newton's law of cooling to estimate the time it will take for the container to cool from 50 degrees to 49 degrees.
If a beam is incident normal (perpendicular to the surface) to a plane mirror, what is the angle of reflections
A space vehicle is coasting at a constant velocity of 28.5 m/s in the +y direction relative to a space station. The pilot of the vehicle fires a RCS (reaction control system) thruster, which causes it to accelerate at 0.523 m/s2 in the +x direction.
In some places, insect "zappers", with their blue lights, are a familiar sight on a summer's night. These devices use a high voltage to electrocute insects.
