Hello aspirant,

In eleventh-grade physics, kinematics focuses on characterizing motion without taking into account the forces that cause it. Displacement, velocity, acceleration, and time are important ideas, with evenly accelerated motion receiving particular attention.

Correct Answer: District Consumer Disputes Redressal Forum

Solution : The correct answer is (a) District Consumer Disputes Redressal Forum

The District Consumer Disputes Redressal Forum is the appropriate authority at the district level to handle consumer complaints and take action against businesses, including supermarkets, for various consumer protection violations, such as selling expired food products. The State Consumer Disputes Redressal Commission and the National Consumer Disputes Redressal Commission are higher-level authorities that handle appeals and more significant cases, but for most cases, the initial action would be taken by the District Consumer Disputes Redressal Forum. Consumer Protection Councils play a different role in consumer advocacy and education but don't have the authority to take direct action against businesses.

A man goes from a to b at v1 speed and  returns from b to a at v2 speed.

Let distance between a and b = d

let time taken by man go from a to b = t1 and time taken by man return from b to a =t2

As we know,

time = distance / speed

so, t1 = d /v1   and  t2= d/v2

ATQ,

average speed = total distance/total time

= (d+d) / (t1+t2 )

= (d+d) /(d/v1 + d/v2)

= 2d / (d(v2+v1)/v1*v2)

= (2v1*v2) / (v2+v1)

Answer = 2(v1*v2) / (v2+v1)

Hi Aspirant,

Kinematics is an important chapter and  it includes laws of motion,Rotational Motion which comprises of omprises of basic concepts of rotational motion, force, torque, and angular momentum. It also includes gravitationlike  Universal law of gravitation, Kepler's law of planetary motion.

Hope it helps!!

Hi

As per your question In this method the investigation starts with a response system in equilibrium; the

response to be studied has finished, and no in addition changes take place. The external conditions are

then altered very rapidly; the gadget is then now not at equilibrium, and it relaxes to a brand new

equilibrium.

Ex: These reactions can take vicinity in seconds or in minutes. ... For example, combustion of LPG

gasoline in kitchen takes region in a few seconds so it's far a quick reaction. In the same way reaction of

an acid like HCl with a base including NaOH takes area in seconds to provide a salt NaCl and water may

be very fast response.

Hope helpful.

Hello Shivendra, According to the kinetic theory of gases, at absolute temperature, The normal active vitality of gas particles is straightforwardly relative to total temperature just; this suggests all sub-atomic movement stops if the temperature is diminished to total zero.

Hope this helps.

Thank you.

Hey Raushan,

Hope You are doing Well!

COULOMB'S LAW:

It is the law that the force (attraction/repulsion) between two charges is equal to the product of their charges and inversely proportional to the square of distance between them.

LIMITATIONS OF COULOMB'S LAW:

1)Applicable only in cases when inverse law works.

2)Applicable For Point Charges at Rest

3)It is Difficult to apply Coulomb's Law,when charges are in arbitrary shape.

Hope This was helpful!

All The Best!

Keep Smiling :)
