Scientists have changed the model of the atom as they have gathered new evidence. one of the atomic models is shown below.
a large black cross in a purple circle with a black line around the purple, with 10 small green balls dispersed within the purple circle.
what experimental evidence led to the development of this atomic model from the one before it?
a few of the positive particles aimed at a gold foil seemed to bounce back.
the colors of light emitted from heated atoms had very specific energies.
equations were used to identify regions around the nucleus where electrons would likely be.
cathode rays were bent in the same way whenever a magnet was brought near them.

Which bonds are found inside a water molecule

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.

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?
