Uhh it is used to detirmine heat
A transmitter “encodes” or modulates messages by varying the amplitude or frequency of the wave – a bit like Morse code. At the other, a receiver tuned to the same wavelength picks up the signal and 'decodes' it back to the desired form
I think it’s A or D
Answer:
You were a freeloader of my questions, so I'll be one too.
2.72 N
Explanation:
Step 1:
From the basic formula in electrostatics
F = E * q
where F = Force due to charges
E = Electric field strength
q = Charge
Step 2:
From the given question
q= 
E = 
F = 
N
The reactants are <em>Calcium</em>, <em>Hydrogen</em> and <em>Oxygen</em>.
We need 1 atom of <em>Calcium</em>, 4 atoms of <em>Hydrogen</em> and 2 atoms of <em>Oxygen</em>.
Hope this helps.
