Aball is thrown at an angle upward from a raised platform. it is released from a height of 2.1m above the ground. the ball raises into the air and comes back to land on the ground 4.2s later a horizontal distance of 40.0m away. what is the initial velocity of the ball and the maximum height of the ball above ground?

In a voltaic cell, electrons flow from the (positive/negative) to the (positive/negative) terminal.

In a stagnant pool of water, a crayfish may spend much of its time lying with one side of its carapace near the surface of the water. in this position, it will move the walking legs on that side in a rhythmic back-and-forth motion. explain the likely function of this behavior.

High schoolphysics 5+3 pts a neon light consists of a glass tube with metal wires at each end. when connected to a high-voltage source, the gas glows. if a fly lands on the glass tube, what will most likely happen? a) the fly will not feel a shock because the glass conducts any free electrons back into the gas. b) electrons will flow directly from the metal wires along the glass and shock the fly. c) the fly will not feel a shock because the glass insulates it from the electrons in the gas and the metal. d) electrons that are moving through the gas will be conducted through the glass and shock the fly.
