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
Ptolemy's model theorizes that Earth is the center of the universe, and that all planets and the Sun revolve around it. If Venus is between the Earth and the Sun, then the Venus must always be crescent or all dark. <em>Thus, it is impossible to see a full or gibbous face of Venus. </em>Later on, this was disproved by Galileo when he saw through the telescope all phases of Venus. Hence, the heliocentric theory was approved instead.
a) Gravitational force only
b) Normal force only
c) Gravitational force, normal force, and frictional force
d) Gravitational force and normal force
