An aircraft makes a horizontal circular turn. The air craft enters the turn with velocity of v = 300i+400j, 20 seconds later it leaves the turn with velocity of v = 400i - 300j. Determine the acceleration of the aircraft in g units.

um i think if u go to the settings on ur acc then u should b able to scroll down and deactivate it to answer ur other question lol

Explanation:

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.

i believe the answer would be:

d. violin, clarinet, french horn, and tuba
