Answer with Explanation:

There are two types of Observation:

1.→ Qualitative Observation : In which things are Selected on the basis of Quality ,like Color,Shape , Size ,Behavior,Nature of a person, etc...

2.→Quantitative Observation: Representation is done with the help of numbers ,Alphabets or Special Characters or by Combining all of them.

Option A: A Change of State: ------It denotes Quality.

Option B: A change in Size : ----It can be both Quality as well as Quantity.For Example Animal loosing and gaining weight can be represented in terms of both numbers as well Quality.For example :50-30,Fat-Thin.

Option C: A number-----It denotes Quantity.

Option D: A Color----It denotes Quality.

⇒A Number is : is must a quantitative observation.

In which electric circuit would the voltmeter read 10 volts ?

ki77a [65]

Given that,

Voltage = 10 volt

Suppose, The three resistance is connected in parallel and each resistance is 12 Ω. find the current in the electric circuit.

We need to calculate the equivalent resistance

Using formula of parallel

$\dfrac{1}{R}=\dfrac{1}{R_{1}}+\dfrac{1}{R_{2}}+\dfrac{1}{R_{3}}$

Put the value into the formula

$\dfrac{1}{R}=\dfrac{1}{12}+\dfrac{1}{12}+\dfrac{1}{12}$

$\dfrac{1}{R}=\dfrac{1}{4}$

$R=4\ \Omega$

We need to calculate the current in the circuit

Using ohm's law

$V=IR$

$I=\dfrac{V}{R}$

Where, V = voltage

R = resistance

Put the value into the formula

$I=\dfrac{10}{4}$

$I=2.5\ A$

Hence, The current in the circuit is 2.5 A

A “real” image occurs when light rays actually intersect at the image, and become inverted, or turned upside down. ... In flat, or plane mirrors, the image is a virtual image, and is the same distance behind the mirror as the object is in front of the mirror. The image is also the same size as the object.
