Explanation

An electric circuit is a closed path through which electric current flows.

It enabling the transfer of electrical energy.

Electric current is measured in amperes using an ammeter.

Explanation

In Young's double-slit experiment, if the slit separation is halved and the screen distance is doubled,

The fringe width will become four times its original value.

This is because fringe width is directly proportional to the screen distance (D) and inversely proportional to the slit separation (d),

So halving 'd' and doubling 'D' results in a multiplication of the fringe width by 2 / (1/2) = 4. 

Explanation

Formula:

KE=1​/2mv2

Where:

• $m=$ (mass)

• $v=$ (velocity)

Step 1: Square the velocity

v^2=^52=25

Step 2: Multiply by mass

m⋅v^2=2×25=50

Step 3: Multiply by 1/2

KE=1​/2×50=25J

Explanation

A state function is a thermodynamic property

That depends only on the current state of a system, not on the path taken to reach that state.

Pressure, temperature, and entropy are all considered state functions

Because their values are determined solely by the system's conditions (like its composition, volume, and energy)

And not the process used to get there. 

Explanation

The measurable quantities that describe the condition of a system are called state variables. 

Explanation

An extensive property is a quantity that depends on the amount of matter present in a system.

Volume directly relates to the amount of space a substance occupies,

Meaning if you double the amount of substance, the volume will also double. 

Explanation

The breakdown of water using an electric current is called electrolytic decomposition.

The more specific term is electrolysis, and when applied to water, it is called the electrolysis of water. 

Explanation

- When an object falls through a fluid (like air), it accelerates until forces balance.

- At terminal velocity:

  - Air resistance = Weight (mg)

  - Net force = 0

  - So, acceleration = 0

- Common in skydiving and falling raindrops.

Explanation

. Ohmmeter (for measuring resistance):

- Measures resistance directly in ohms (Ω).

- Faster and more efficient than a voltmeter + ammeter combination.

- Used in electronics to test resistors and circuit continuity.

Explanation

Digital multimeters are measuring instruments that can measure quantities:

Such as voltage, current, and resistance.
