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?

An isolated conducting spherical shell carries a positive charge. part a which statement (or statements) about the electric field and the electric potential inside and outside the spherical shell is correct? which statement (or statements) about the electric field and the electric potential inside and outside the spherical shell is correct? electric potential inside the shell is constant and outside the shell is changing as 1/r2 both the electric potential and the electric field does change with r inside and outside the spherical shell electric potential inside and outside the shell is constant, but not zero electric potential inside the shell is constant and outside the shell is equal to zero electric field inside and outside the shell is constant (does not change with the position r), but is not equal to zero electric field inside and outside the shell is changing as 1/r (where r is the distance from the center of the sphere) electric field inside is equal to zero and outside the shell is constant, but not zero electric potential inside the shell is constant and outside the shell is changing as 1/r electric field inside and outside the shell is changing as 1/r2 electric field inside is equal to zero and outside the shell is changing as 1/r2 electric field inside and outside the shell is zero electric field inside is constant and outside the shell is changing as 1/r
