I'm not sure but I think that if objects are closer (less distant), than the gravitational pull is stronger. I'm sorry if I couldn't really help I remember learning about this kind of.
Answer:
Explanation:
According to the given reaction,
heat released by thecombustion of 2 molecules of Methanol, 
we know that molecular mass of Methanol, 
∴12 gram of methanol = 
we know 1 mole = 
so,
Heat from the combustion of 
:
<u>Now the mass of water that can be heated from 23.5°C to 88.2°C :</u>
KE=1/2 mv^2
=1/2(150kg)(15m/s)^2
=16875 kgms^-2
I believe this would be frequency, as wavelength measures the waves themselves, and a period is a section of time. Wave speed is the speed of their movement.
