The changes in celsius are the same as those in kelvins. the difference between the two scales is that 0 celsius is about 273 kelvins and that 0 kelvins is about -273 celsius (note the minus sign)
<span>Nothing, in terms of the chemistry.
The distance between the electrodes affects the electrical resistance very slightly. Increasing the distance increases the resistance and reduces the current slightly, which reduces slightly the amount of product.
For most practical applications, for electrolysis done in a beaker, varying the distance between the electrodes will make little difference.
Increasing the concentration of the electrolyte will increase the current flow because there are more charged particles to carry charge, and increase the product yield.</span>
<h2>
So, the correct answers are:</h2>
Travels in longitudinal waves
Travels most slowly through a gas
Speeds up when temperature is increased
Is caused by vibration
Explanation for correct answers:
Yes, it does travel in longitudinal waves
Yes, sounds weird, but travels faster in the water
Yes, does speed up when temperature is increased
And yes, Is caused by vibration.
<h2>
Wrong answer is:</h2>
Can travel through a vacuum
Explanation for wrong answer:
actually, in space, there is NO sound, because there are no particals for the sound to vibrate with, there's just empty SPACE.
Answer:
acceleration = 0.8181 m/s²
Explanation:
given data
mass = 1.1 kg
apart d = 1 m
charge q = 10 μC
to find out
What is the initial acceleration
solution
we know that acceleration is
acceleration = 
.................1
here force = 
here q1 q2 is charge and r is distance and Coulomb constant k = 9 × 
Nm²/C²
force = 
force = 0.9 N
so from equation 1
acceleration = 
acceleration = 0.8181 m/s²
Answer:
Explanation:
We shall apply the formula of Doppler effect here
F( APPARENT) = F( REAL ) X V/(V + Vs) [ v is velocity of sound and Vs is velocity of source.
415 = 440 X 343/343+Vs
142345 + 415Vs = 150920
415 V₀ = 8575
V₀ = 20.66 m/s.
