Explanation:
given that the raven flies south for
time= 10 sec
speed= 10km/s
we know that speed=distance/time
distance=speed*time
distance=10*100
distance=1000m
distance=1km
also flies
distance=0.5km = 500m
time= 50 sec
speed= distance/time
speed=500/50
speed= 10m/s
speed= 0.01km/s
The average speed of an object is defined as the distance traveled divided by the time elapsed.
average speed= (1000+500)/10+50
average speed= (1500)/60
average speed= 25m/s
average velocity= (10km/s+0.01km/s)/2= 10.01/2= 5.005km/s
Answer:
0.25A
1.0A
2.5A
Explanation:
this is only for the calculated current column on edge
I believe your answer would be False
They would only be elements because compounds and molecules consist of multiple elements
Do not use water on chemical fires such as magnesium, or on electrical fires.
A decomposition reaction would be the electrolysis.
<span>Usually it is separated in two equations, one for oxidation
and another for reduction, which are called half reactions:</span>
2 H+ + 2e− → H2
2 H2O → O2 + 4 H+ + 4e−
Then you should add them up. In order for the equation to be
balanced, the first equation has to be added twice:
2 H+ + 2e− + 2 H+ + 2e−+2
H2O → H2+ H2 + O2
+ 4 H+ + 4e−
4 H+ + 4e− +2 H2O → 2H2
+ O2 + 4 H+ + 4e−
Then you should cancel the substances which are both in reactives
and in products, and also the electrons:
2 H2O → 2H2 + O2
And there you have the overall equation for electrolysis.
Electrolysis does not happen naturally – you have to provide
electric energy for it to happen.
A synthesis reaction would be the opposite reaction, which
would be called: electrosyntesis.
2H2 + O2 → 2 H2O
