Answer:
11116.1135295
Explanation:
Finding square roots of of numbers that aren't perfect squares without a calculator.
Example: Calculate the square root of 10 ( ) to 2 decimal places.
Find the two perfect square numbers it lies between.
Divide 10 by 3. ...
Average 3.33 and 3. ( ...
Repeat step 2: 10/3.1667 = 3.1579.
Answer: 9300 kcal
Explanation: Given: Latent heat of fusion of aluminum is 93 kcal/kg.
That is for melting 1 kg of aluminium at 660 amount of heat required is = 93kcal
Thus for 100 kg of aluminium at 660 amount of heat required is=
Thus the amount of energy needed to melt 100 kg of aluminum at the melting point is 9300 kcal.
Answer:
c. Water
Explanation:
The solvent is the substance in which a solute is dissolved to make the solution.
In this case, the water is the solvent, the flavored powder is the solute, and the solution is the final drink.
Answer:
Eelas = 0.25[J]
Explanation:
This problem can be solved using the principle of energy conservation, in this particular case related to elastic energy.
The elastic energy can be calculated by means of the following equation:
where:
k = The spring constant is 50 [N/m]
x = distance compressed = 0.3 - 0.2 = 0.1 [m]
A decrease in it's operating temperature would make a heat engine less efficient. This is because in order to operate, a heat engine needs to be hot and maintain that temperature.
