Select all of the responses below that are true statements The ratio of the effort arm to the resistance arm (i.e. AE/AR) of a lever is equal to the ratio of the Effort distance to the resistance distance (dE/dR) and also to the ratio of the Resistance force to the Effort force (FR/FE) The force due to gravity is a constant on earth The acceleration due to gravity is a constant on Earth. The rods in the eye are responsible for color vision When the density of a uid decreases it will tend to sink relative to the other uids around it. If you decrease the temperature of a uid in a container, the pressure of the uid will increase. When temperature increases, the rate of random molecular motion increases In simple machines, if the machine decreases the distance a force operates over, the size of the force exerted will increase
