Q9.एखाद्या वस्तूवर एकापेक्षा अधिक बले प्रयुक्त असतील तर त्या वस्तूवर होणारा परिणाम हा ______________असतो.

Q9.If more than one force are acting on a body, then the effect on the body is ________.

A) प्रयुक्त निव्वळ बलामुळे
Due to net force

B) शून्य
Zero

C) ऋण
Negative

D) धन
Positive

Explanation:
When multiple forces act on a body, their combined effect is determined by the net force, which is the vector sum of all the individual forces. The net force causes the body to accelerate according to Newton's second law of motion. If the forces are balanced, the net force is zero, and the body remains at rest or in uniform motion. If the forces are unbalanced, the net force causes a change in the body's state of motion.

Q10.अनियमित परावर्तनासंबंधीचे अचुक विधान / समीकरण निवडा.

Q10.Find the correct statement / equation regarding irregular reflection.

A) अनियमित परावर्तनात परावर्तनाचे नियम पाळले जात नाहीत.
Laws of reflection are not followed in irregular reflection.

B) आपतन कोनाचे माप परावर्तन कोना इतके नसते
Angle of incident is not equal to angle of reflection.

C) ) i = r1 ≠ r2 ≠ r3 = ________.

D) अनियमित परावर्तन गुळगुळीत पृष्ठभागावरून होते.
Irregular reflection takes place at smooth surface.

Explanation:
In irregular (or diffuse) reflection, the surface is uneven, causing the reflected rays to scatter in different directions. However, each individual ray still obeys the laws of reflection, where the angle of incidence (𝑖i) equals the angle of reflection (𝑟r) for each point on the surface. Due to the irregularities, the reflected angles (𝑟1,𝑟2,𝑟3,r1,r2,r3, etc.) differ for different rays.

Innumerable images of the glass pieces are formed

D) याचा उपयोग वेगवेगळया रचना शोधण्यासाठी करतात.
It is used to find various designs.

Explanation:
In a kaleidoscope, three mirrors are typically placed at 60° angles to each other, forming an equilateral triangle. This arrangement creates symmetrical and repeating patterns of reflections, producing innumerable images of the objects inside.

Q12.पुढीलपैकी कोणता घटक अणुभट्टीमध्ये न्युट्रॉनची संख्या कमी करण्यासाठी नियंत्रक म्हणुन वापरला जात नाही ?

Q12.Amongst the following which element is not used as controller to reduce the number of neutrons in the nuclear reactor?

A) बेरिलिअम
Beryllium

B) ग्रॅफाईट
Graphite

C) कॅडमिअम
Cadmium

D) बोरॉन
Boron

Explanation:
Graphite is used as a moderator in a nuclear reactor, not as a controller. Moderators like graphite slow down neutrons to sustain the nuclear chain reaction, whereas control elements like cadmium, boron, and sometimes beryllium are used to absorb neutrons and regulate or reduce their number in the reactor.

B) CaO - आम्लधर्मी Acidic

C) KCI - उदासीन Neutral

D) SO2 आम्लारीधर्मी Alkaline

Explanation:
Na2CO3 (Sodium carbonate) is alkaline, not neutral, because it forms a basic solution in water, so statement (1) is incorrect.
CaO (Calcium oxide) is basic, not acidic, because it reacts with water to form calcium hydroxide, so statement (2) is incorrect.
KCl (Potassium chloride) is a neutral salt formed from the reaction of a strong acid (HCl) and a strong base (KOH), so statement (3) is correct.
SO2 (Sulfur dioxide) is acidic, not alkaline, as it dissolves in water to form sulfurous acid, so statement (4) is incorrect.

Explanation:
Chromatography is a widely used technique in pharmaceutical science for identifying and separating components of a mixture based on their different rates of movement through a stationary phase under the influence of a solvent (mobile phase). It is especially effective for separating complex mixtures, such as drugs, active pharmaceutical ingredients (APIs), and other substances.
Centrifugation is used to separate components based on density but is not typically used for detailed separation of complex mixtures in pharmaceutical science.
Method of separation is a general term, not a specific technique.
Distillation is used to separate liquids based on their boiling points but is not the primary method for identifying and separating pharmaceutical components, especially for complex mixtures.
