An object weighs 2.6 N in air and 2.2N when completely immersed in water. Determine the relative density of the object (2mks

Modify the equation fδt=δ (mv) to find the force of friction.

Two thin 80.0- cm rods are oriented at right angles to each other. each rod has one end at the origin of the coordinates, and one of them extends along the x- axis while the other extends along the yaxis. the rod along the x- axis carries a charge of - 15.0 μ c distributed uniformly along its length, and the other rod carries 15.0 μ c uniformly over its length. find the magnitude and direction of the net electrical force that these two rods exert on an electron located at the point (40.0 cm, 40.0 cm). (e

What is the measurement of how fast an object moves relative to a reference point?
