Answer:
8.35 ×
kg
Explanation:
Remember the formula for heat:

You just need to solve for m, doing so you're left with:

Replace the variables with numbers and that's it.
Answer: Really
Explanation:
Just look it up for this page and maybe you will find an anwser sheet.
It would be 1. B 2. A 3. A
efficiency=work output/work input×100
since it exhausts(use up)3000j of heat that's the work input and the 1500j is the work input
efficiency=1500/3000×100
=50%
Answer:A. It is modified by the cell, so there is still more glucose on the outside of the cell than inside it
Explanation: The cells are the primary unit of a living organism,it is the place where cellular respiration takes place, which is the use of oxygen to break down food substances such as Glucose to release energy in the form of Adenosine trisphosphate (ATP) and give out Carbondioxide as a by-product of cellular respiration.
Most of the Glucose enter the cells to get modified through cellular respiration so their is still more Glucose outside than the Glucose inside.
