Atomic weight is Ar of the atom (what you see on the periodic table)
atomic weight<span> is relative </span>atomic mass, so yeah same thing
Answer:
Energy
potential energy kinetic energy
chemical energy thermal energy
joules
Explanation:
chemical energy is a type of potential energy or stored energy. Heat is a kinetic energy and energy is measured in joules.
I would convert my years of age to months, to days, to hours to minutes and finally to seconds. By knowing these facts:
365 days = 1 years
1 day = 24 hours
1 hour = 60 minutes
1 minute = seconds
I would be able to solve it.

Answer:
The correct answer is a) 300 Kg b) 225 Kg c) 400 Kg and d) 600 Kg.
Explanation:
Based on the given value, that is. 40-15-10 shows the compositions of nitrogen, phosphorus, and potassium found in the compound fertilizer in the form of percentage.
41 percent nitrogen is equal to 40/100 = 0.4, 15 percent phosphorus is equal to 15/100 = 0.15, and 10 percent potassium is equal to 10/100 = 0.1.
To find the amount of fertilizer, which is needed per hectare to supply the different nutrients per hectare, there is a need to divide the quantity to be supplied by the percentage composition, now the values comes out as:
a) At 120 Kg per ha, the required nitrogen will be 120/0.4 = 300 Kilogram of fertilizer.
b) At 90 kg per ha, the required nitrogen will be 90/0.4 = 225 Kilograms of fertilizer.
c) At 60 kg per ha, the required phosphorus will be 60/0.15 = 400 Kilograms of fertilizer.
d) At 60 Kg per ha, the required potassium will be 60/0.1 = 600 Kilograms of fertilizer.
