The current is the same at every point in a series circuit, so
each of those resistors has the same current flowing through it.
The current in that particular circuit is
(battery voltage) / (23) amperes.
<span>Acceleration of ball (a) = 9.8 m/s^2
Speed (v) = 24.5 m/s
Time (t) = Acceleration / Time
= v / a
= 24.5/9.8
= 2.5 s
So it will take 2.5 seconds to reach that speed.</span>
Speed= (4.92-2.45) 2.47 m/s

Answer:
(A) 
(B) 
Explanation:
Given:
- diameter of the cylinder,

- mass of piston sealing on the top,

- initial temperature of the piston,

- initial height of piston,

- atmospheric pressure on the piston,

(A)
<u>Initial pressure of gas is the pressure balanced by the weight of piston:</u>



<em>Which is gauge pressure because it is measured with respect to the atmospheric pressure.</em>
(B)
Given:
- Final temperature,

<u>Now, volume of air initially in the cylinder:</u>



Using gas law:
........................................(1)
<em>∵In every condition of equilibrium the gas pressure will be balanced by the weight of the piston so it is an </em><em>isobaric transition</em><em>.</em>
∴
<u>Hence eq. (1) is reduced to:</u>

putting respective values:
