Answer the questions all of them pls its 30 points I spent Describe what characterizes science and explain the difference between a hypothesis, a theory and a scientific law.

Explain Newton’s 3 laws of motion by using the example of a rollercoaster.

Breakdown and explain, in terms of frame of reference, if you’re inside a moving train everything on the outside can seem to be moving.

Propose a way to explain to someone the differences between the terms: speed, velocity and acceleration.

If you’re in a car moving at a high speed, and you stop abruptly, what would happen when wearing a seatbelt as opposed to not wearing a seat belt? Which of Newton’s 3 laws would apply?

In the future, people will only enjoy one sport: electrodisc. in this sport, you gain points when you cause metallic discs hovering on a field to exchange charge. you are an electrodisc player playing the popular four disc variant. the disks have charges of qa = −8.0 µc, qb = −2.0 µc, qc = +5.0 µc, and qd = +12.0 µc. (1) you bring two disks together and then separate them. you measure the resulting charge of these two disks and find that it is +5.0 µc per disk. which two disks did you bring together? (a) a and b (b) a and c (c)a and d (d)b and c(e) b and d (f) c and d. (2) you bring three disks together and then separate them. you measure the resulting charge of these three disks and find that it is +3.0 µc per disk. which three disks did you bring together? a, b, and c (a) a, b, and d (c) a, c, and d (d) b, c, and d. (3) given the resulting charge of each disk measured in (b) is +3.0 µc, how many electrons would you need to add to a disk of this charge to electrically neutralize it? electrons
