Which of the following describes power. Work done over a period of timeA force applied over a distanceChange in velocity over a period of timeThe difference in position

diagram is missing, but i will try to explain your doubt.

answer:

amplitude is the maximum displacement or distance moved on a point of a vibrating body or wave measured from its equilibrium position.it is equal to half the length of vibration path.

the old price per ounce is c/4.

the new price per ounce is c/3.6.

the ratio of the old price to the new one is

(c/4)/(c/3.6) = (c/c)×(3.6/4) = 0.9 . . = 9/10 . . "nine tenths" in either form

distance = 150m

displ = root (50 ^2 + 100^2)

root(2500+10000)

root 125000

did yall get answers for this yet
