Answer:
A. Chemical to electric energy
Step-by-step explanation:
The cells in the device undergo a chemical process to produce electric energy first
Answer:
A. 2
Step-by-step explanation:
The computation is shown below:
As we know that
The Volume of a right circular cylinder is

Here r is the radius
And h is the height
Now it is mentioned that the height of the right circular cylinder P is double to the height of the right circular cylinder Q
Now let us assume h be the height of cylinder p
And, H be the height of cylinder Q
So the equation is
h = 2H ........(1)
Also
The radius of both the cylinders would be the similar length
So
we assume the r be the radius of both cylinders
Now
The Volume of cylinder Q = 
And for P it is 
Now substitute equation 1

Hence, the correct option is A.
Yeah I think so I just took a wild guess and looked at my measurement sheet
I don’t know how to solve it on a graphing calculator but i can solve x for you♀️.
