Nano scale ranges between ............m to .............m
-
10-9 to 10-7
-
10-8 to 10-7
-
10-5 to 10-7
-
None
Correct Answer
A. 10-9 to 10-7Explanation
The correct answer is 10-9 to 10-7. The nano scale ranges between 10-9 meters to 10-7 meters. This range represents the length scale at which materials and structures exhibit unique properties and behaviors due to their small size. At the nanoscale, quantum effects become more pronounced, and materials can have different optical, electrical, and mechanical properties compared to their bulk counterparts. This range is crucial for various fields such as nanotechnology, electronics, and medicine.Rate this question:

The greatest number from the following is .................
-
10-9
-
10-6
-
10-3
-
10-2
Correct Answer
A. 10-2Explanation
The greatest number from the given options is 10-2. When subtracting a smaller number from a larger number, the result is a larger number. Therefore, 10-2 is greater than 10-3, 10-6, and 10-9.Rate this question:

The ratio between surface area and volume increase lead to ......................
-
Increase rate of chemical reaction
-
Decrease rate of chemical reaction
-
Rate of chemical reaction constant
-
None
Correct Answer
A. Increase rate of chemical reactionExplanation
When the ratio between surface area and volume increases, it means that the surface area of the substance in question is increasing relative to its volume. This increased surface area allows for more contact between the substance and its surroundings, which in turn increases the chances of chemical reactions occurring. Therefore, an increase in the ratio between surface area and volume leads to an increase in the rate of chemical reaction.Rate this question:

Its part of billion part is ..............................
-
Nano meter
-
Nano
-
Nano scale
-
None
Correct Answer
A. NanoExplanation
The correct answer is "nano." This suggests that the given part is a billionth part of something, specifically measured in nanometers. The term "nano" is commonly used to indicate a scale of measurement that is extremely small, making it an appropriate choice for the given context.Rate this question:

In macro scale , gold has ..............color
-
Yellow
-
Red
-
Blue
-
B/c
Correct Answer
A. YellowExplanation
Gold has a yellow color in macro scale. This is due to its unique atomic structure and the way it absorbs and reflects light. The metal's electrons absorb certain wavelengths of light, particularly in the blue and green regions of the spectrum, while reflecting yellow light. This selective absorption and reflection of light gives gold its distinct yellow color.Rate this question:
