3. At the end of the lab all of the matter (such as the string, the ball and the books) stayed in the area. The potential energy, that was stored in the ball on the high shelf and suspended weights
as well as the stored mechanical energy of the sling shot, had left the system in the form of
sound, motion and heat. What type of energy system (open, closed or isolated) is
represented by the lab device and why? (3 points)
Type: :
Why?

Astudent is given an assignment to demonstrate diffraction. he takes a photograph of a straw in a glass of water. the straw appears bent at the water level. which best describes this example? a) this is a good example of diffraction. b) this is an example of dispersion and not diffraction. c) this is an example of refraction and not diffraction. d) this is an example of reflection and not diffraction.

Will give brainliest! which statement best describes the similarities between fundamental forces? electromagnetic and strong nuclear forces influence the interaction between charged particles within an atom. gravitational and magnetic forces are both types of charges that occur in nature. nuclear and magnetic forces are both related to mass and weight. strong nuclear force is most like electrical force because they are both related to distance.
