Does taking 1 ml of solution y (pure bleach) out of the first beaker change the solution’s concentration? what would the concentration of the second beaker be? if beaker #2 is a 1% solution of y, and beaker #3 is 1/100th of that in the final solution, what percentage solution would beaker #3 be?

If the force applied to an object remains constant, is more power needed for the object to move faster ? explain

An athlete swings a ball, connected to the end of a chain, in a horizontal circle. the athlete is able to rotate the ball at the rate of 8.13 rev/s when the length of the chain is 0.600 m. when he increases the length to 0.900 m, he is able to rotate the ball only 6.04 rev/s. (a) which rate of rotation gives the greater speed for the ball? 6.04 rev/s 8.13 rev/s (b) what is the centripetal acceleration of the ball at 8.13 rev/s? m/s2 (c) what is the centripetal acceleration at 6.04 rev/s? m/s2
