Answer:
its b option balance hi your last question
Answer:
The description of the given scenario is described in the explanation segment below.
Explanation:
- As a charge passes through some kind of potential gap, the electrical task is undertaken as well as energy will be transferred.
- The Potential difference seems to be an amount of work performed per unit charge and is denoted by "V" as well as a charge is denoted by "Q".
<u>The energy transferred could be determined by using the following equation or formula:</u>
⇒ Energy transferred = charge × potential difference
The only evidence you have that you exist as a self-aware being is your conscious experience of thinking about your existence. Beyond that you're on your own. You cannot access anyone else's conscious thoughts, so you will never know if they are self-aware.
The RC time constant, also called tau, the time constant (in seconds) of an RC circuit, is equal to the product of the circuit resistance (in ohms) and the circuit capacitance (in farads), i.e.

Here,
R = Resistance
C = Capacitance
Replacing we have that



Therefore the time constant of this circuit is 
Answer:
option A
Explanation:
given,
compression for lower setting = x
work done to compress in lower setting = 5 J
compression in higher setting, x' = 2 x
work done in higher setting = ?
Work done in compression of spring at lower setting

............(1)
Work done in compression of spring at higher setting




from equation (1)

W' = 20 J
Work take for the higher setting is equal to 20 J
Hence, the correct answer is option A
