An electron enters a large solenoid at a 7.9 ∘ angle to the axis. A) If the field is a uniform 3.7×10−2 T , determine the radius of the electron's helical path if its speed is 1.0×107 m/s .
b)Determine the pitch (distance between loops) of the electron's helical path

Select all of the following that are equal to an impulse of 20 unitsa) force= 5, time= 5.5b) force= 25, time= 0.8c) force= 0.1, time= 200d) force= 10, time= 2(its b, c, and d)(also in order to find answer they have to add to get the unit)ex= 25x.8=20 or .1x200=20

Agroup of students were investigating the force of gravity. they began by dropping a foam ball from a height of 3 meters into a bucket of sand. the ball hit the sand in 0.306 seconds. they dropped additional balls of approximately the same diameter, but of different masses. here is the data they collected. based on this experiment and the collected data, what would their conclusion be?
