Calculate: First measure the mass of the flowerpot in the Gizmo. Then predict the weight of the flowerpot on each planet (multiply the mass by that planet's strength of gravity). Finally check your predictions by
actually weighing the flowerpot on each planet, using the Gizmo.

You throw a baseball directly upward at time t = 0 at an initial speed of 12.3 m/s. what is the maximum height the ball reaches above where it leaves your hand? at what times does the ball pass through half the maximum height? ignore air resistance and take g = 9.80 m/s2.

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.

In positive numbers less than 1, the zeros between the decimal point and a non-zero number are blank significant
