After it was discovered, astronomers predicted uranus's orbit using newton's laws of motion and gravity, which had worked extremely well for all of the other planets. to their surprise, they found that their observations of uranus's motion through the sky did not match their predictions. which of the following would be the most logical next step?

a. check for other previously undiscovered factors that might alter uranus's orbit while still allowing it to obey newton's laws of motion and gravity.
b. newton's laws of motion and gravity must be modified to match the data.
c. newton's laws of motion and gravity have been falsified, so they should be scrapped in favor of a completely new hypothesis.
d. if the data doesn't match newton's laws of motion and gravity, then the data must be bad, so this finding should be disregarded.

Matt is driving down 7th street. he drives 150 meters in 18 sec. assuming he doesn’t slow down or speed up, what is his speed?

While studying chemical reactions and conservation of matter, sarah's class conducted a variety of experiments. sarah and her lab partner found the mass of a wax candle and placed the candle in a flask. the students lit the candle and let it burn to completion. all that was left was wax and charred candle wick. per their teacher's instructions, the students found the mass of the products. their data can be seen in the data table. formulate a hypothesis the students could test to explain why the experiment did not support the law of conservation of matter. a) the students could repeat the experiment using different candles; there might have been a flaw in the candle. b) the experiment should be repeatable. the students should run several trials and then take an average of the after mass in each trial. c) the students should have someone in the class check their measurement skills as they repeat the experiment. they may have made an error using the balance. d) the students should burn the candle in a container that has some type of lid so that any gas that is a product of the reaction can be contained and massed. submit

Pl asaaap ! match the term to the correct description. a type of wave that transfers energy where the particles in the medium move perpendicular to the direction in which the energy is traveling. a type of wave that transfers energy where the particles in the medium move parallel to the direction in which the energy is traveling. movement that is back and forth, like an equal sign = a type of wave that transfers energy where the particles in the medium move in a circle motion while the energy travels left or right. movement that is like a t transfers energy from one location to another 1. wave 2. parallel movement 3. perpendicular movement 4. transverse wave 5. longitudinal wave 6. surface wave
