57.27 degree

Gaurav Seth 2 months, 1 week ago

The degree measure of 1 radian (taking π = (22 / 7)) is  57°16’22” (approx.)

π = radian = 180°

∴ 1 radian = <center>180°</center>  


= <center>180 × 7°</center>  


=   <center>630</center> = 57 <center>3</center> °
11 11


= 57°   <center>3</center> × 60" = 57° <center>180'</center>  
11 11


= 57°16' <center>4</center> × 60" = 57°16'22"

Antigens are large molecules of proteins, present on the surface of the pathogen- such as bacteria, fungi viruses, and other foreign particles. When these harmful agents enter the body, it induces an immune response in the body for the production of antibodies.


For example: When a common cold virus enters the body, it causes the body to produce antibodies to prevent from getting sick.

Dark reaction is also called carbon-fixing reaction. It is a light-independent process in which sugar molecules are formed from the carbon dioxide and water molecules.

The dark reaction occurs in the stroma of the chloroplast, where they utilize the products of the light reaction.

Plants capture the carbon dioxide from the atmosphere through stomata and proceed to the Calvin cycle.

In the Calvin cycle, the ATP and NADPH formed during light reaction drives the reaction and convert six molecules of carbon dioxide into one sugar molecule, i.e. glucose.

(K-273)/100=C/100=(F-32)/180 So, (K-273)/100=25/100=(F-32)/180 => K= 298 => F= 77

Gaurav Seth 3 months ago

The normal room temperature which would be comfortable for living is around 20 - 25° C.

In chemistry, The upper limit 25°C is taken as Standard room temperature .

We know that,
Temperature on Celsius + 273 = Temperature on Kelvin.

25°C = 25 + 273 = 298K .

Therefore, The standard room temperature in Kelvin is 298 k

Andreas Vesalius was a Belgian born anatomist and a physician. Vesalius published his most important work, 'De Humani Corporis Fabrica Libri Septem' (seven books on the fabric of human body), generally known as Fabrica. Fabrica is the most famous anatomy book ever written and also the first book on human anatomy to be reasonably accurate. He is thus known as the father of anatomy.

Newton’s laws of motion imply the relationship between an object’s motion and the forces acting on it. In the first law, we come to understand that an object will not change its motion unless a force acts on it. The second law states that the force on an object is equal to its mass times its acceleration. And, finally, the third law states that for every action, there is an equal and opposite reaction.

What are some daily life examples of Newton’s 1st, 2nd and 3rd laws of motion?

Riding a bicycle is a good example of Newton’s 2nd law. In this example, the bicycle is the mass. The leg muscles pushing on the pedals of the bicycle is the force.

  • The motion of a ball falling through the atmosphere, or a model rocket being launched up into the atmosphere are both excellent examples of Newton’s 1st law.
  • You hit a wall with a certain amount of force, and the wall returns that same amount of force. This is an example of Newton’s 3rd law.

C=e°A/(d-t+t/k) Where d=distance b/w plates t=thickness of dielectric k= dielectric constant

Gaurav Seth 4 months ago

Consider a parallel plate capacitor without any dielectric medium (vacuum) between the plates. Let A be the area of the plates and d be the plate separation. The two plates have charges Q and – Q. Since d is much smaller than the linear dimension of the plates (d2 << A), 

Plate 1 has surface charge density σ = Q/A and plate 2 has a surface charge density – σ. Using earlier result of the electric field in different regions is: Outer region I (region above the plate 1), 

Outer region II (region below the plate 2), 

In the inner region between the plates 1 and 2, the electric fields due to the two charged plates add up, giving 

The direction of electric field is from the positive to the negative plate. Thus, the electric field is localised between the two plates and is uniform throughout. For plates with finite area, this will not be true near the outer boundaries of the plates. The field lines bend outward at the edges – an effect called ‘fringing of the field’. Hence σ will not be strictly uniform on the entire plate. 

However, for d2 << A, these effects can be ignored in the regions sufficiently far from the edges, and the field there is given by Eq. (1). Now for uniform electric field, potential difference is simply the electric field times the distance between the plates, that is,

The capacitance C of the parallel plate capacitor is then 

which, as expected, depends only on the geometry of the system.

Dimensional of a physical quality are powers to which base qualities are raised to represent that quality.

Gaurav Seth 4 months, 3 weeks ago

Dimensions of a physical quantity are powers (exponents) to which base quantities are raised to represent that quantity. They are represented by square brackets around the quantity.

  • Dimensions of the 7 base quantities are – Length [L], Mass [M], time [T], electric current [A], thermodynamic temperature [K], luminous intensity [cd] and amount of substance [mol].

Force = Mass x Acceleration = [M][L]/[T]2 = [MLT-2]

Aristotle is known as the “Father of Biology” because he extensively studied the natural world and contemplated its origins using scientific insights and systematic observations rather than attributing it to divine intervention. He was also the first to uncover the relationship between animals and establish a system of classification. 

During his time, Aristotle made many observations about the local flora and fauna, for instance, he was the first to document that an octopus can change its colour when disturbed. He also named close to 500 species of animals, identifying their characteristic features and documenting them.
