Answer:
7.2 V
Explanation:
The three batteries are connected in series to the terminals of the phone: it means that they are connected along the same branch, so the current flowing through them is the same.
This also means that the potential difference across the phone will be equal to the sum of the voltages provided by each battery.
Here, the voltage provided by each battery is
V = 2.4 V
So, the overall voltage will be
V = 2.4 V + 2.4 V + 2.4 V = 7.2 V
<span>I don't think there is enough information from the question. If you are asked to calculate the number of microbes in a certain area., then it should be that the total area or maybe the volume of that should be given so you can estimate the number of microbes. Hope this helps.</span>
I think its suicidal ideation......

Answer:
The velocity of the bus at B is 
Explanation:
Let's take position B as base point .
From the diagram height between point B and A ia mathematically evaluated as


From the question we are told that
The velocity at location A is
According the law of conservation of energy

Where
is the potential energy at A which is mathematically represented as

is the kinetic energy energy at A which is mathematically represented as

is the kinetic energy at A which is mathematically represented as

Where
is the velocity at location B
So

Making
the subject of the formula

Substituting values
