Let the total distance covered by the particle be 2s. Then

We can derive Newton’s third and first laws from the second law.

The correct option is C third and first laws from the second law
We can derive Newton's third and first laws from second law. If force on particle is zero, then according to Newton's second law

F=ma

0=ma

a=0 (Since mass cannot be zero)
So, this shows that the body moves with constant velocity or remains at rest if no external force on the system. This is the statement of first law itself.

Suppose an isolated system of two bodies A and B. Suppose A exerts force F₁ on B and B exerts F₂ on A. Now, rate of change of momentum of A is dp₁/dt and that of B is dp₂/dt. Therefore, from second law,

F₁=dp₁/dt …(i)

F₂=dp₂/dt …(ii)

Adding (��) and (����), we get

F₁+F₂=dp₁/dt+dp₂/dt

Since the system is isolated, so the total change in momentum or rate of change of momentum dp₁/dt+dp₂/dt should be zero. Thus, F₁+F₂=0 or F₁=−F₂.This is the statement of third law.

The property by virtue of which the free surface of a liquid at rest behaves like an elastic stretched membrane tending to contract so as to occupy minimum surface area is known as surface tension. By the definition of surface tension.

Wall that permits *heat" to flow through them,such as engine block is called diathermic wall.
wall Perfectly insulating ball that doesn't allow the flow heat to them are called adiabatic walls.

We know that if frequency of an external forced  oscillation is equal to the natural frequency of the body, then amplitude of the forced oscillation of the body becomes very large. This phenomenon is known as resonant vibration. Therefore, resonance is an example of forced vibration.

Van de Graff generator- is an electrostatic generator which is devised to produce very high voltage by means of an endless belt collecting electrostatic charge from a source and transferring it to a large isolated metal sphere on which a large change accumulates.

60/40 = l/100-l, = R/8

so R=12

now changed position 8 is proportional to l and 12 to (100-l)

8/12 = l/100-l

l = 40ohm

Photoelectric effect, phenomenon in which electrically charged particles are released from or within a material when it absorbs electromagnetic radiation. The effect is often defined as the ejection of electrons from a metal plate when light falls on it. In a broader definition, the radiant energy may be infrared, visible, or ultraviolet light, X-rays, or gamma rays; the material may be a solid, liquid, or gas; and the released particles may be ions (electrically charged atoms or molecules) as well as electrons.

We use the concept of conservation of energy and distance of closest approach in Rutherford's alpha scattering experiment to find the radius of the nucleus is proportional to the Mass Number. The consequence of this is that the density of the nucleus is a constant, independent of mass number for all nuclei.
 

Nucleus contains only neutrons and protons.

We can observe from the table that Yˉ=A.B⇒Y=AB
So, the table represents a NAND gate.

In quadrant sin, cos tan, cot, sec, cosec all +ve .In second quadrant sin and cosec are +ve. in 3rd quadrant tan and cot are positive.And in 4th cos and sec are +ve.

2x² - 4x + 3 = 0
x = [-(-4) +- (√16-24)]/2(2)
x = (4 +- i√8)/4
x = (4 +- 2i√2)/(2 * √2 * √2)
x = 2(2 +- i√2)/(2 * √2 * √2)
x = 1 +- i/√2

Sum (S_n) = a x (rⁿ -1)/(r-1)
5460 = 4 x (4ⁿ -1)/3
16380 = 4ⁿ⁺¹ - 4

16384 = 4ⁿ⁺¹

4⁷ = 4ⁿ⁺¹

7 = n + 1

n = 6

Let I=∫(0 to k) 1/[1 + 4x²]dx = π8
Now, ∫(0 to k) 1/[4(1/4 + x²)]dx
= 2/4[tan⁻¹ 2x]0 to k
= 1/2tan^-1 2k − 0 = π/8
1/2tan⁻¹ 2k = π8
⇒ tan⁻¹ 2k = π/4
⇒ 2k = 1
∴ k = 1/2

The two curves y² = 4x and y = x meet where x² = 4x i.e ..where x = 0 or x = 4 . Moreover , the parabola lies above the line y = x between x = 0 and x = 4 . Hence , the required are is :

This statement is wrong: A ten rupee's note will not buy you

Correct Statement will be: A ten rupee note will not buy you.

In passive voice, the object of the active voice sentence ("the papers") becomes the subject in the passive voice sentence, and the subject ("the teacher") becomes the object.

Refer to, “The long-term trends for flood impact in India have been one of declining loss of lives and cattle since the decadal high of 1971-80, but rising absolute economic losses, though not as a share of GDP. “

It is clear from the passage that the long term trends of impact of floods in India have been on the decline in terms of lives of people and cattle lost but on the other hand the economic losses have quantified multiple times during this particular time duration. Among the given options, we can choose Option A only since it gives us the correct information regarding the data on lives lost in floods since 1970s till date. Others can be eliminated since they do not follow from the passage.

This makes option A the correct choice among the given options.

Explanation:
Let's visualize Hemant's movements step by step:
1. Hemant started at point A and walked 40 meters North to point B.
2. Then, he turned left (towards West) and walked 50 meters to point C.
3. Finally, he turned left again (towards South) and walked 40 meters to point D.
Now, let's analyze his final position relative to the starting point:
- Hemant is 40 meters South of point B (his position after the first move), so he is at the same vertical level as point A (his starting point).
- Hemant is 50 meters West of point A (his starting point).
Hence, Hemant's final position relative to his starting point is:
- 50 meters West
Therefore, the correct answer is:
D: 10 m, West

HCF (240, 300, 120) = 60

All others denote various feelings.

M x N → M is the mother of N

N % S → N is the wife of S

and S + T → is the father of T.

Hence, M is the maternal grandmother of T.

Potassium permanganate is a point-of entry treatment method that oxidizes dissolved iron, manganese, and hydrogen sulfide into solid particles that are filtered out of the water.

The objective of the MoU between MoD and FSSAI is to promote the use of millets and healthy eating practices among the Armed Forces and ensure the availability of safe and nutritious food. The collaboration aims to create awareness about the nutritional benefits of diet diversity and millet-based food products among Army personnel. It also seeks to introduce millet-based menus in mess, canteens, and other food outlets under the MoD. Therefore, option b is the correct answer.

The man in the photo is the son of the sister of Bajpai. Hence, Bajpai is the maternal uncle of the man in the photograph.
