20Ah is the number of charge that can be supplied at 20A for 1 hour. If you wish to drain it in 19 minutes, then the current is:
Answer:
There are three types of mechanical waves: transverse waves, longitudinal waves, and surface waves. :/
Explanation:
What do you mean when you say "this" graph ? I don't see any graph.
First of all, I'm sure you don't have a "velocity versus time" graph.
You may have a "speed versus time" graph, that doesn't show any
information about the direction of the motion.
As you look at your graph ... a feat that's impossible for me ...
-- If the line is horizontal, then speed is not changing. If the direction
of motion is also not changing, then there is zero acceleration. Sadly,
the graph most likely doesn't carry any information about the direction.
It's possible that the speed is constant but the direction is changing.
Then acceleration isn't zero, but you can't tell that from the graph.
-- If the line is proceeding upward from left to right, whether it's straight
or curving, then there is positive acceleration.
-- If the line is proceeding downward from left to right, whether it's straight
or curving, then there is negative acceleration, or what some people might
call "positive deceleration".

Answer:
The equivalent resistance is equal to 18 Ω.
Explanation:
The given resistors are 2 Ω, 5 Ω and 11 Ω.
They are arranged such that the current flowing through all three resistances is the same. It means the resistors are connected in a series combination.
The equivalent resistance in series combination is given by :
So, the equivalent resistance is equal to 18 Ω.
