All of these statements about flux are true, except for the last one - <span>When turning a surface inside of an electric field, the maximum flux is achieved if the electric field vector and the surface vector are perpendicular.
These vectors don't have to be perpendicular, which is why this statement is incorrect, whereas the rest of them are true. </span>
Answer:
19 contraction cycles could theoretically be fueled by the complete combustion of one mole of glucose.
Explanation:
Complete Question
Assume that the complete combustion of one mole of glucose to carbon dioxide and water liberates 2870 kJ/mol.
One contraction cycle in muscle requires 67 kJ, and the energy from the combustion of glucose is converted with an efficiency of 45% to contraction, how many contraction cycles could theoretically be fueled by the complete combustion of one mole of glucose? Round your answer to the nearest whole number.
Complete combustion of glucose liberates 2870 kJ/mol.
Complete combustion of one mole of glucose will liberate 2870 × 1 = 2870 kJ
The energy from the combustion of glucose is converted with an efficiency of 45% to contraction.
So, the amount of energy from the combustion of one mole of glucose that is converted to contraction is
45% × 2870 = 1,291.5 kJ
One contraction cycle requires 67 kJ of energy, so, 1291.5 kJ will cause
(1291.5/67) contraction cycles = 19.28 contraction cycles = 19 contraction cycles to the nearest whole number.
Hope this Helps!!!
Answer:
Explanation:
Displacement is the shortest distance or path between two points.
1) Displacement = √(36² + 45²) = 57.63 miles
2) Displacement = √(100² + 500²) = 509.9 meters
3) Displacement = √(60² + 40²) = 72.11 miles
4) Displacement = √(700² + 500²) = 860.23 miles
5) Displacement = 300 - 300 = 0 miles
6) Displacement = 200 + 100 = 300 miles
7) Displacement = √(650² + 650²) = 919.24 miles
8) Yes, since a distance is moved in a direction

Failed the assignment but got this answer correct.
Answer : The specific heat capacity of the alloy
Explanation :
In this problem we assumed that heat given by the hot body is equal to the heat taken by the cold body.
where,
= specific heat of alloy = ?
= specific heat of water =
= mass of alloy = 21.6 g
= mass of water = 50.0 g
= final temperature of system =
= initial temperature of alloy =
= initial temperature of water =
Now put all the given values in the above formula, we get
Therefore, the specific heat capacity of the alloy
