Answer:$0.1125
Explanation:
power=750 watts
Power=750/1000=0.75 kilowatts
$0.15 for 1 kilowatts-hour
$h for 0.75 kilowatts-hour
$h=(0.75 x 0.15)
$h=$0.1125

well, since player b is obviously inadequate at athletics, it shows that player b is a woman, and because of this, she would not be able to hit the ball. The magnitude of the initial velocity would therefore be zero.

First you need to solve for time by using
d=(1/2)(a)(t^2)+(vi)t
1m=(1/2)(9.8)t^2 vertical initial velocity is 0m/s
t=.45 sec
Then you find the horizontal distance traveled by using
v=d/t
1.3m/s=d/.54sec
d=.585m
Then you need to find the time of player B by using
d=(1/2)(a)(t^2)+(vi)t
1.8m=(1/2)(9.8)(t^2) vertical initial velocity is 0
t=.61 sec
Finally to find player Bs initial horizontal velocity you use the horizontal equation
v=d/t
v=.585m/.61 sec
so v=.959m/s
For question 1 if you have your acceleration equal to -9.8m/s^2 then you can find how fast it is traveling when it hits the water. You would use the equation Vf=Vi+a(t). You are looking for your Vf. Vi is 0m/s. a is -9.8m/s^2. t is 3.87s. If you now plug in what you have and solve you would end up with Vf=-37.926. For how far did it drop use the equation, d=Vi(t)+1/2(a)(t)^2. plug in the Vi, a, and t and solve. Then you are left with the distance vertically being 73.38681m (don't forget sig figs). (When you solve for d it ends up being negative, but because you can't ever go backwards in distance it has to be positive)

Answer:
plastics are susceptible to degradation due to ultraviolet (UV) light from the sun. With enough exposure, UV light can cause a chemical reaction in the plastic, which results in scission, or severing, of those big polymer molecules.
