Here's what you need to know about alternatives of Earth

-


The search for alternative Earth-like planets, also known as exoplanets, is a topic of great interest in the field of astronomy. While there are billions of planets in the galaxy, the vast majority of them are not suitable for life as we know it. However, there are a few exoplanets that have been discovered that are considered to be "Earth-like" and could potentially support life.

  1. Kepler-186f: Kepler-186f is an exoplanet that orbits a red dwarf star located about 500 light-years from Earth. It is about the same size as Earth and is considered to be in the "habitable zone," meaning it is at the right distance from its star to potentially support liquid water, a key ingredient for life as we know it.

  2. Kepler-438b: Kepler-438b is another exoplanet located about 640 light-years from Earth that is considered to be in the habitable zone. It is slightly larger than Earth and is thought to be rocky.

  3. Proxima Centauri b: Proxima Centauri b is an exoplanet that orbits the star Proxima Centauri, which is the nearest star to Earth at just 4.2 light-years away. While it is slightly larger than Earth and is considered to be in the habitable zone, it is also much closer to its star, which means it is likely to be much hotter than Earth.

  4. TRAPPIST-1e: TRAPPIST-1e is an exoplanet that orbits the star TRAPPIST-1, which is located just 39 light-years from Earth. It is about the same size as Earth and is considered to be in the habitable zone.

  5. LHS 1140b: LHS 1140b, is a super-Earth exoplanet that orbits a red dwarf star in the constellation Cetus, 40 light-years away. It is about 1.4 times the size of Earth and has a rocky surface. The planet is located in the star's habitable zone, where it receives about the same amount of light as Mars does in our solar system.

Estimation of total chlorophyll by Aron's method

-
Purpose:- Estimation of total chlorophyll by Arnon's method. Requirement:- Spectrophotometer Buchner's funnel, filter paper test tube, Fresh leaves. measuring cylinder pestle & mortar 80% Acetone  Formula:- 20.2 (A645) +802 A663) / 1000 x W Principle:- Chlorophyll is extracted in 80% acetone & the absorption at 660 nm& 645 nm are read in s spectrophotometer using the absorption co-efficient, the amount of chlorophyll is calculated Procedure:- 1) Weigh 1 gm of finely cut & well mixed representative sample of a leaf or fruit tissue into a clean mortar 2) Grind the tissue to a fine pulp with the addition of 20mil of 80% acetone   3) Centrifuge (5000 rpm for 5 min) & transfer the supernatant to a 100 ml volumetric flask  4) Repeat this procedure until the residue is colorless wash the mortar and pestle  thoroughly with 80% acetone and collect the clear washing in the volumetric flask 5) Make up the volume to 100 ml with 80% acetone  6) Read the absorbance of the

Aim:-  To determine the value of Stefan's constant. Apparatus:-  Black body radiation unit, Ammeter, Voltmeter, connecting wires, DC source. Theory:-  Stefan's constant: A physical constant denoted by  σ , is the constant of proportionality in the Stefan's-Boltzmann law- the total intensity radiated over all wavelength increases as the temperature increases Procedure:- 1) The electrical connections are made as shown in the circuit diagram. 2) Copper black body radiator is preheated to  30 0 C   by setting maximum voltage in the power supply 3)after the temperature indicator indicates a temperature of about    30 0 C , the voltage is reduced to some value  4) increase the voltage in steps of 0.2 V and note down the current, hence calculate power l. 5) Determine the value of Stefan's constan t. Observations:-  Room temperature t o =t+273=......of 2) surface area of the black body  A=4π r 2  = .........m square Calculation  σ  = P/ AT 4 Results:- 1)Stefan's constant st

Pre-Emphasis & De-Emphasis Networks

Aim:-  To draw the frequency response of Pre-emphasis & De-emphasis networks. Introduction:- Educational trainer a useful kit for the demonstration of Pre-emphasis & De-emphasis at different time constants & plot the graph of the frequency response of Pre-emphasis and De-emphasis networks. The kit consists of 200 Hz-20 kHz audio oscillator 70µ sec & 50µ sec De-emphasis networks.  Pre-Emphasis Circuit Diagram:- DE-Emphasis Circuit Diagram:- Theory:- Pre-emphasis refers to boosting the relative amplitudes of the modulating voltage for higher audio frequencies from 2 to approximately 15 kHz . De-emphasis means attenuating those frequencies by the amount by which they are boosted.  However, Pre-emphasis is done at the transmitter and De-emphasis is done in the receiver. The purpose is to improve the signal-to-noise ratio for FM reception. A time constant of 75µ sec is specified in the RC or L/Z network for Pre-emphasis and De-emphasis. Tabular column:- Pre-Empha
