As compared to pure water, a body in salty water will:
Sink more
Sink less
Remain same
Depends on the way the body is immersed
This question relates to Archimedes' principle and the concept of buoyancy. Buoyancy, or the upward force exerted by a fluid, depends on the density of the fluid. We need to compare the densities of pure water and salty water to determine the effect on a submerged body.
Correct Option: B) Sink less. Because salty water is denser than pure water, it exerts a greater buoyant force on the body. This increased buoyant force means the body needs to displace less volume of water to support its weight, causing it to sink less or float higher.
The question asks to identify a colloidal solution from the given options. To answer this, we need to understand the definition and characteristics of a colloidal solution, and then classify each option accordingly.
B) Paint is a colloidal solution. It consists of pigment particles dispersed in a liquid medium, where the particle size falls within the colloidal range (1-1000 nm), and it exhibits characteristics like the Tyndall effect.

If KNIFE is coded as MPKHG, then what does the code DTGCF stand for?
The problem involves decoding a word based on a given coding pattern. We need to identify the rule by which KNIFE is coded as MPKHG and then apply the reverse of that rule to decode DTGCF.
Original word: KNIFE
Coded word: MPKHG
The coding rule is to shift each letter two places forward in the alphabet.
Since the coding rule is adding 2, the decoding rule will be subtracting 2 from each letter.
Combining the decoded letters, DTGCF stands for BREAD.
C) BREAD is the correct word derived by applying the reverse coding rule (subtracting 2 from each letter) to DTGCF.

The problem describes a scenario where a student performed an incorrect operation (multiplication instead of division) and obtained a result. We need to find the result of the correct operation. We will first determine the original number and then perform the correct division.
The student multiplied the number by 3 and got 89.1.
According to the problem statement, if the number is \(x\), then:
\[ x \times 3 = 89.1 \]To find \(x\), divide the incorrect result by 3:
\[ x = \frac{89.1}{3} \] \[ x = 29.7 \]The student was asked to divide the number by 3. So, we need to divide the original number \(x\) (which is 29.7) by 3.
\[ \text{Correct Answer} = \frac{29.7}{3} \] \[ \text{Correct Answer} = 9.9 \]Correct Option: C) 9.9
