Answer:
total energy lost = 16.1 KJ
Explanation:
Heat of vapor to water = 1.84j/gK is - because have a loss of energy
Heat lost during cooling from 155 to 100 = 1.84x 5 x(155 + 273 - 100+273) = 506J
latent heat of steam = 2260J/g x 5g = 11300J
Heat lost during cooling from 100 to 0 = 4.18 x5 x (100 - 0) = 2090J
Heat due to fusion is = 336J/g x 5g = 1680J
heat to cool ice of 0 to -55 = 2.09J/gK x 5g x (0 -(-55)) = 574.75J
the sum of all H = H of reaction
506J + 11300J + 2090J + 1680J + 574.75J = 16150.75J = 16.1KJ
total energy lost = 16.1 KJ

Calculating the Perimeter of the rectangle:
In option D
Calculating the difference between length and width:
In option E
Calculating the ratio of length to width:
Answer:
Explained
Explanation:
The electrons get rubbed off some items onto others. This causes an excess or electron on one item and deficiency of electron on the other. Therefore an electrostatic force of attraction is produced and hence clothes often cling together after tumbling in a clothes dryer
Albert Einstein was a German-born theoretical physicist. He developed the general theory of relativity, one of the two pillars of modern physics. Einstein's work is also known for its influence on the philosophy of science.
Zero acceleration means the object's velocity is not changing.
So the object is moving in a straight line, at a constant speed
that could be anything (including zero) as long as it's constant.
