Glucose is important to plants because it is a source of energy that can be converted into other components like starch or cellulose; these components are necessary forcell structures such as the cell walls and for the plant's development.Glucose is also necessary for respiration in plants.
Answer:
The volume of water that was in the kettle is 1170 
Explanation:
Given:
Power, P = 2.0 kW = 2000 W, Mass of stainless steel, 
= 710 g = 0.71 kg at temperature of 
Part A:
If it takes time, t = 3.5 minutes to reach boiling point of water 
, then from conservation of energy,
Total energy supplied by the burner = Total heat gained by the water and the stainless steel to rise from to
i.e. Pt = 
(100 - 20 ) + 
(100 - 20 )
= 
= 1.17 kg
where = 4200 J/Kgk (specific heat capacity of water), = 450 J/Kgk (specific heat capacity of steel)
But volume of water in the the kettle, v = 
∴ v = 1170
<span>In a rocket combustion chamber the rocket exhaust is forced out of the nozzle by the rapid expansion of exhaust gases and the directing shape of the rocket nozzle. The equal and opposite reaction is that the rocket nozzle (and hence the shuttle it is attached to) is forced in the other direction</span>
