Answer:
The toy's energy is 18 J.
Explanation:
We have, a 4 kg toy is lifted off the ground and falls at 3 m/s. It is required to find toy's energy.
The toy will have kinetic energy due to its motion. The energy is given by :

So, the toy's energy is 18 J.
Answer:
ummmmmmmmmmmm ask your teacher or perant for help
Explanation:
so umm ask an adult or teen figure and maybe you will get it write not sure do
Answer:
(a) Total time will be 8.05 hour
(B) Total cost will be $417.6
Explanation:
We have given dryer uses 16 A of current so current i = 16 A
Voltage V = 240 volt
Time t = 45 minutes =45×60 = 2700 sec
So power P = VI = 240×16 = 3840 W
So energy E = power×time = 3840×45×60 = 9396 KJ
(A) Now current in the computer i = 2.7 A
Voltage V = 120 V
So power P = 120×2.7 = 324 W
Now computer is using energy of dryer
So time by which it will use energy is 
So time will be 8.05 hour
(b) Cost per kilowatt is $0.12
So total cost =3480×0.12 = $417.6
