Amass m = 0.6 kg is released from rest at the top edge of a hemispherical bowl with radius = 1 meters. the mass then slides without friction down the inner surface toward the bottom of the bowl. at a certain point of its path the mass achieves a speed v = 4.22 m/s. at this point, what angle \theta\: θ ( in degrees) does the mass make with the top of the bowl?

A3.9 g aluminum foil ball with a charge of +4.1×10−9 c is suspended on a string in a uniform horizontal e⃗ field. the string deviates to the right and makes an angle of 30∘ with the vertical. part a part complete what information about the e⃗ field can you determine for this situation? what information about the field can you determine for this situation? only the magnitude of e⃗ only the direction of e⃗ both the magnitude and the direction of e⃗ none of the above previous answers correct part b determine the magnitude of the electric field. express your answer with the appropriate units. e e = nothing nothing request answer part c determine the direction of the electric field. determine the direction of the electric field. to the right to the left away from you toward you
