A parallel plate capacitor has plates of dimensions 20cm by 20cm separatedby 2mm. the dielectric constant of the material between the plate is 5and the plates are connected to a voltage source of 500v. calculate a).the capacitance, b)the charge on either plate c)the energy density d) the total energy stored in the capacitor ​

The image shows a pendulum in simple harmonic motion the pendulum starts at a and swing to e

Me pl give an example of a collision in real life. use the law of conservation of energy to describe the transfer of momentum. be sure and discuss the momentum before and after the collision occurs. you will need at least 3 sentences to thoroughly answer this question.

Amoving company collects data about couches they move and displays the data in a table. the force along the ramp, the angle of the ramp, and the height the couch is raised to are shown. which statements correctly compare the work done to move the couches? check all that apply. the same amount of work is done for couches 1 and 3. the same amount of work is done for couches 2 and 3. the work for couch 1 is greater than the work for couch 2. the work for couch 2 is less than the work for couch 3. the work for couch 3 is greater than the work for couch 1. the work for couch 2 is greater than the work for couch 1.
