Solve the following equation using the GRASS method 2. A kettle was tested for its energy efficiency. Its power rating was 900 W. The
temperature of 1.0 L of water increased from 24°C to 48°C in a time of 4 minutes
and 30 seconds.

a. Calculate the energy efficiency of the kettle.

b. Why is the kettle not 100% efficient? What happened tỏ the "missing" energy?

3.2x10^7

as we probably am aware that our atmosphere or air have various levels, each level has different gasses, and each gas has another porousness. at the point when the light originates from lower porousness to higher penetrability, it alters its course. with the goal that implies that when the light originates from the moon to the earth, it alters it's course a lot more occasions. it essentially implies that the state of the light piece of the moon is changed on the earth.

not copied too! hope this !

joke:

h o h o hope you have a merry christmas!

higher potential

explanation:

because it is in a high speed so it must move into a of high potential
