Answer:
i want to say nuclues but again i also think that it is electron shells
Hello!
Yes, it needs oxygen to metabolize sugars that, in the end, produce carbon dioxide (CO2).
Answer:
A
-1440J
Explanation:
Hello,
This question requires us to calculate the work done on a object to move it from point A to point B
Data
Mass = 60kg
Initial velocity (V1) = 8.0m/s
Final velocity (V2) = 4.0m/s
Workdone on an object is equal to force applied on the object to move it through a particular distance.
Work done = force × distance
Force (F) = mass × acceleration
Distance = s
F = Ma
Work done = M× a × s
But a = velocity (v) / time (t)
Work done = mvs / t
But velocity = distance/ time
Work done = mv × v/
Work done = mv²
Work done = ½mv²
Workdone = ½M(V2² - V1²)
Workdone = ½ × 60 (4² - 8²)
Work done = 30 × (16 - 64)
Workdone = 30 × (-48)
Work done = -1440J
Work done = -1.44kJ
The workdone on the object is equal to -1.44kJ
The energy it plays is heat energy ahahha an
The reaction will come to an end if all the reactants are used up. The reaction's limiting reactant is reactant B.
Limiting Reactant: The limiting reactant is the one that is consumed first and sets a limit on the quantity of product(s) that can be obtained.
This reactant is the one that restricts the production of products throughout the reaction. The reaction will come to an end if all of the reactants are used up.
surplus reactant
This is the limiting reactant that is present in excess and reacts with it all. Oxygen in the surroundings, as an illustration.
When all of the reactant B has been utilized, the reaction ends.
