Question: Read the following paper:
N.D. Finkelstein, W.K. Adams, C.J. Keller, P.B. Kohl, K.K. Perkins, N.S Podolefsky, and S. Reid, "When learning about the real world is better done virtually: A study of substituting computer simulati
This paper compares teaching circuits using a a virtual lab and using a real lab.
Prompts: 1. Has this paper persuaded you to use the PhET or similar simulation when you teach circuits? Why or why not? (Note: If you do not teach circuits, consider what you would do if you did teach circuits.)
2. In general, what are the strengths and weaknesses of virtual labs? What are the strengths and weaknesses of hands-on labs?
Glenn starts his day by walking around a circular track with radius 48 m for 15 minutes. what is his angular position with respect to where he starts
The aorta is a major artery, rising upward from the left ventricle of the heart and curving down to carry blood to the abdomen, find the magnitude (in m/s2) of the blood's centripetal acceleration
A lidar (laser radar) gun is an alternative to the standard radar gun that uses the Doppler effect to catch speeders. A lidar gun uses an infrared laser and emits a precisely timed series of pulses of infrared electromagnetic waves.
question a converging lens f 14.7 cm is located 24.1 cm to the left of a diverging lens f -6.64 cm. a postage stamp
A vertically polarized photon is incident onto a polarizer with a transmission axis oriented an angle of 80? counter-clockwise from the horizontal.
temperatures are often measured with electrical resistance thermometers. suppose that the resistance of such a
If the electron above passes directly between the pair of parallel plates used in this experiment, what voltage must we apply to the plates to send the electron crashing into one of the plates? (Note, this is Vd) The electron is initially moving p..
What is the magnitude of the acceleration of the girl?
Two points, A and B, are separated by 0.0360m. The potential at A is +81.1 V, and that at Bis +41.6 V. Find the magnitude of the constant electric field between the points.
Two conductors having net charges of +17.0 µC and -17.0 µC have a potential difference of 17.0 V between them. Determine the capacitance of the system
In a time t, N hailstones strike a glass window of area A at angle theta to the window surface. Each hailstone has a mass m and a speed v. If the collisions are elastic, what are the average force and the pressure on the window?
Circular loop carries current I. It is placed in constant magnetic field in such a way that field lines are perpendicular to the plane of the circle. What is the force on the loop? Does the magnetic field have any effect on the loop?
