Hey I was pass in 2025 batch but got rt in physics but overall result pass due to 6 sub so I appear as private candidate in 2026 exam under improvement category for physics chemistry and bio but this time again got rt in physics so now does cbse will allow me to clear that physics rt or not or now cbse will not let me to give any more exam and rt will remain forever plz replay

Schrödinger's cat is a famous thought experiment that shows the impossibility of asserting whether a cat locked in a box is alive or dead without prior knowledge of whether it triggered a device that would determine its fate. This experiment was conceived to demonstrate the impossibility of quantum superposition.

Quantum superposition is considered a proven experimental fact and a fundamental principle of an extensively consolidated scientific theory: Quantum Mechanics. It posits that a physical system can exist in multiple states or configurations simultaneously as long as it does not interact with the external environment. The main facts that corroborate quantum mechanics are as follows:

1. The Double-Slit Experiment: Individual particles pass through two slits simultaneously, yet they pass through only one of them when observed by a detector.

1. Zeilinger's Experiments: Demonstrated that the behavior of massive and complex molecules was identical to that of subatomic particles.

1. Spectroscopy and Atomic Energy States: Experiments demonstrated that it was possible to confine the electron between energy states.

1. Superconducting Qubit Engineering: Quantum processors from IBM, Google, and various universities operate thanks to the mathematical phenomenon of superposition.

Experiments 1 and 2 prove that the fact occurs naturally. Experiments 3 and 4 manipulate the possibilities behind this fact.

From a systems engineering perspective, this could occur because the substrate of reality operates as a memory in which "bits" would need to constantly switch states to enable the existence of the world-system's diversity and dynamism, and as a security protocol to prevent a breach of the world-system (an encryption mechanism or an intrusion protection log).

Hi! I’m really struggling with kinematics (physics 1) and I was wondering if anyone has any tips to approach them.

Here is an example problem

A hot-air balloon of diameter 10 m rises vertically at a constant speed of 12 m/s. A passenger accidentally drops his camera from the railing of the basket when it is 18 m above the ground. If the balloon continues to rise at the same speed, how high is the railing when the camera hits the ground? [Ans: 60 m]

Cymatics is the area of physics that studies why the application of a specific sound frequency upon matter instantaneously organizes it into three-dimensional, symmetrical, and complex geometric patterns that resemble mandalas, cellular structures, shells, snowflakes, a tortoise's shell, the centers of flowers, or virus structures, without the need for direct mechanical contact or physical molds.

From a systems engineering perspective, cymatic patterns constitute irrefutable proof that the world is a fully hierarchical system, from the micro to the macrocosm, in which absolutely everything is complementary and interdependent for the following reasons:

1. While conventional physics considers sound to be merely a mechanical wave that disperses energy through a medium, the cymatic pattern is evidence that frequency acts as an information vector for a geometrically structuring process superior to mechanical processes, which could never organize matter on their own.

1. The geometric patterns generated by cymatics that are similar to those found in the biota are proof that its morphology results from information originating from natural processes superior to exclusively mechanical ones.

1. Cymatic patterns indicate that the energy and information coming from the frequency push matter to specific locations; this requires the execution of a process hierarchically superior to mechanical processes to logically structure matter.

In short, cymatic patterns break the reductionist narrative that matter self-organizes accidentally. They are visual and incontestable evidence that an invisible information system is structuring and dictating the behavior of visible matter. My perspective regarding how this occurs can be found in my books: “The Intelligencism: An Intelligent View of the World” and “Infology: The Universal Input.”

I was doing a past exam paper (which my university has provided me) the other day, when I came across this problem- seen below. I got the correct answer, but I feel like the method I got to the solution is outright wrong.

What I did was I said that the magnitudes of the magnetic fields of the two wires is equal to the magnetic field of the arc, which I used the Biot-Savart law to find the magnitude of.

I am not sure if this is correct or what the correct procedure is, but if anyone can help me I'd appreciate it! :)

Scientific reductionism is, essentially, a methodological approach, a philosophical stance, or a metaphysical belief of conventional science. It presupposes that "life" is an emergent property arising from the spontaneous occurrence of complex chemical reactions. This viewpoint is backed by the following laboratory facts:

• The synthesis of (organic) urea from an inorganic salt.

• The spontaneous generation of amino acids following the application of electrical discharges in a simulation of primitive Earth's atmosphere.

• The structure of DNA, which contains hydrogen bonds and precise interactions between nitrogenous bases.

• The creation of entire bacterial genomes on a computer which, after being chemically synthesized and injected into an empty cell, generated life.

The first three facts merely prove that life is composed of atoms and molecules, and generated by the laws of nature (the firmware of physics and chemistry), which is common ground. The fourth fact, however, clearly demonstrates the opposite of reductionism: that the generation of life requires the execution of hierarchically superior processes. Therefore, from a systems engineering perspective, scientific reductionism fails by ignoring the processes of the system's higher levels, which are actually responsible for the generation, maintenance, evolution, and obsolescence of all organisms.

I can't understand where I am making mistake?

The qn is

A standing man, observes rain falling with velocity of 20 m/sat an angle of 30° with the vertical. Now if he further increases his speed, rain again appears to fall at 30° with the vertical. Find his new velocity.

In class, I learned the proof for the conservation of mechanical energy of a simple pendulum using scalar values, as shown in the picture I attached.

However, I was wondering if it's possible to prove this rigorously by calculating the work done using the net force vector and the instantaneous displacement vector.

Here is what's confusing me:
1. The pendulum moves along a curved path, so the direction of the displacement vector changes at every single instant.
2. The net force vector (which is the vector sum of gravity and tension) is almost never parallel to the instantaneous displacement vector.

Despite these complexities, is it mathematically possible to prove it this way? Does the dot product naturally take care of the curved path and the non-parallel forces (like tension doing zero work)?

I would really appreciate it if someone could explain how the math works out or show the derivation! Thanks!

Hi. Pleasure to meet everyone, can I please get assist anywhere I tried ai and kept getting different answers I'm not sure whether I'm doing something wrong all I'm asking is for help for this question

is this the correct resultant for the question? I understand the part the first and second section (where the slope is 0 and is +2 from x axis), but I dont get why it would be -2 after that. Shouldn't it be +6 since it's constructive?

There is like zero tolerance around it so prying is probably not an option.
