A circular coil with 12 loops of copper wire is placed in the horizontal plane. The magnetic field is uniform and is oriented 40 degrees above the plane of the loop. The radius of the loops of wire is 3.50 cm. If the magnetic field changes at a uniform rate of 12.0 mT/s, what is the absolute value of induced emf in the coil

If you touch a hot light bulb and get burned, that is an example of a. radiation b. convection c. conduction

One day, after pulling down your window shade, you notice that sunlight is passing through a pinhole in the shade and making a small patch of light on the far wall. you see that the patch of light seems to be a circular diffraction pattern. it appears that the central maximum is about 1 cm across and you estimate that the distance from the window shade to the wall is about 3 m. what is (a) the average wavelength of sunlight? (b) the diameter of the pinhole?

Gas cloud 1 is likely to form a star. gas cloud 2 is not. based on this information, match the given conditions with each cloud
