mr. Smith challenged his students to create an electromagnet that will pick up more paper clips than anyone else in the class Timmy is very excited and begins to collect all of the necessary materials he finds a d cell battery and Irondale and a large roll of copper wire what did Jimmy do using just these materials to increase the strength of his electromagnet to pick up the maximum amount of paper clips answer a cut the iron nail in half to use as the core answer be only attached the battery to one end of the nail and cersei increase the number of coils of copper he puts around the nail answer d decrease the number of coils of copper wire he puts around the nail

Which notation is used to represent an alpha particle? a. b. c. d.

Your starship, the aimless wanderer, lands on the mysterious planet mongo. as chief scientist-engineer, you make the following measurements: a 2.50-kg stone thrown upward from the ground at 14.0 m/s returns to the ground in 5.70 s ; the circumference of mongo at the equator is 2.20×10^5 km ; and there is no appreciable atmosphere on mongo. (a) the starship commander, captain confusion, asks for the following information: what is the mass of mongo? (b) if the aimless wanderer goes into a circular orbit 2.20×10^4 km above the surface of mongo, how many hours will it take the ship to complete one orbit? (c) an unmanned spacecraft is in a circular orbit around the moon, observing the lunar surface from an altitude of 44.0 km . to the dismay of scientists on earth, an electrical fault causes an on-board thruster to fire, decreasing the speed of the spacecraft by 23.0 m/s . if nothing is done to correct its orbit, with what speed (in km/h) will the spacecraft crash into the lunar surface?

Give an example in which the electrical energy changes to light energy
