1. What is the Kinetic Energy of a 260 kg object that is moving with a speed of 26 m/s?

Explanation:

so you just have replace the figures were they is mass replace with 260 and were they is velocity replace with 26squared then if you square the 26 you will get 676 then multiply everything you will get the answer

two charges are fixed in place on the x-axis as shown. the charge at x = 0 is negative and has magnitude q = 2 μcoulombs (1 μcoulomb = 10-6 coulombs). the charge at x = d, (d = +12 cm), is positive and has magnitude q = 4 μcoulombs. find a point x = xo along the x-axis at which the electric field is zero.

layers of the earth affect the waves and these effects are seen on instruiments such as seimometers
