Answer:
The source of carbon in a glucose molecule produced by photosynthesis is carbon dioxide
A positively charged ion is referred to as a cation, it is formed through the loss of valence electrons.
Answer:
1.40 × 10⁻²⁰ J
Explanation:
Step 1: Calculate the mass of 1 atom of argon
The molar mass of argon is 39.95 g/mol, that is, 6.02 × 10²³ atoms of Ar have a mass of 39.95 g. We can use this relation to find the mass of 1 atom of Ar.

Step 2: Convert the mass of 1 atom of argon to kilograms
We will use the relationship 1 kg = 1,000 g.

Step 3: Calculate the kinetic energy of 1 atom of Ar moving at 650 m/s

Because the force of gravity is pulling down on the object.
I would say A but then again im not too sure so hope that makes it easier to somehow
