An unstable atomic nucleus has a mass of 17.010-27kg, and starts out at rest. when it decays, it the original nucleus disintegrates into three particles. one particle has a mass of 5.0010-27kg and velocity of 6.00106 jm/s, and a second particle has a mass of 8.4010-27kg and velocity of 4.00106 im/s. calculate (a) the velocity of the third particle and (b) the total increase in kinetic energy as a result of the decay. (note that this kinetic energy actually comes from the mass of the original nucleus, according to e = ∆mc2, but only a tiny amount of mass is turned into energy, so we don’t have to worry about it for this problem.)

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

There are two routes similar in terrain; however, one route has an incline of approximately 28 degrees, and you must decide on which route to take. what is the maximum road grade that your fully loaded ecv can climb?
