Answer:

Materials required : TALL glass, jar , bell and candle .

Method : TAKE a glass jar. Attach a small bell to the bottom of the cap of the jar. Close the jar with the cap. Shake the bottle and note the sound made by bell. Now open the jar , place lighted candle in it and close thr jar again. WAIT for the candle to be extinguished. Shake the bottle again. The sound is not produced.

The oxygen is taken up by the candle.

So, the bell does not PRODUCE any sound.

This proves that sound NEEDS a medium to travel.

Answer:

Following are the THREE types of equilibrium :

1. Stable Equilibrium
2. UNSTABLE Equilibrium
3. Neutral Equilibrium

1. Stable Equilibrium : A body is said to be in stable equilibrium if after a slight tilt it returns to its previous POSITION.

Examples :

• Chair lying on the floor
• The heavy base of the vehicle
• Table lying on the ground
• Cone lying on its base by lowering its center of gravity
• BOTTLE lying on its base

2. Unstable Equilibrium : If a body does not return to its previous position when sets free after the slightest tilt is said to be in unstable equilibrium.

Example :

• A bottle standing on the edge of its mouth
• A cone resting on its apex
• A book PLACED on its edge

3. Neutral Equilibrium : If a body remains in its new position when disturbed from its previous position, it is said to be in a state of neutral equilibrium.

Examples :

• Ball moving on the ground
• Motion of sphere
• A roller
• A pencil lying horizontally
• An egg lying horizontally on a flat surface .

Answer:

The Galileo's LAW of ODD numbers states that the distances traveled are proportional to the squares of the elapsed TIMES. In other words, in equal successive periods of TIME, the distances traveled by a free-falling body are proportional to the succession of odd numbers(1, 3, 5, 7, etc.)

ANSWER:

Concurrent forces are forces that pass through the same point. RESULTANT is a SINGLE force that can replace the effect of a number of forces. "Equilibrant" is a force that is exactly opposite to a resultant. Equilibrant and resultant have equal magnitudes but opposite directions

The DIFFERENCE between a resultant and equilibrant vector is that resultant vector is a direct QUANTITY, one with both magnitude and direction, while the equilibrant vector is a force equal to, but opposite of, the resultant sum of vector forces, that force which balances other force

Answer:

A TRADITIONAL thermostat has two PIECES of different metals BOLTED together to form what's called a bimetallic strip (or bimetal strip). ... When the strip gets hot, one of the metals expands more than the other so the whole strip bends very slightly. Eventually, it bends so much that it breaks open the CIRCUIT.

Explanation:

Calorimetry is the act of measuring the heat of chemical reactions or physical CHANGES, or the SCIENCE of making such MEASUREMENTS. Calorimetry is performed with a CALORIMETER. The word calorimetry is derived from the LATIN word calor, meaning heat and the Greek word μέτρον, meaning measure.

Answer:

Reversible process: A process carried out in such manner that at every stage, the driving torce isnonly infinitesimally greater than the OPPOSING forcenand it can be reversed by an infinitesimal increase innforce and the system exists in equilhbrium with itsnSurroundings throughout, is called a reversible proEsS

Features:

(a) This is a hypothetical process.

(b) Driving force is infinitesimally greater than the opposing force throughout the change.

C)The process can be reversed at any point by making infntesimal changes in the conditions.

(d) The process takes place infinitesimally slowly involving infinite number of STEPS.

(e) At the end of every step of the process, the system attains mechanical equilibium, hence, throughout the process, the system exists in temperature-pressure cquilibrium with its Surroundings.

(f) In this process, maximum work is obtained.

(g) Temperature remains constant throughout the isothermal reversible process.

IRREVERSIBLE process : - It is defined as the unidirectional process which proceeds in a definite DIRECTION and cannot be reversed at any stage and in which driving force and opposing force differ in a LARGE magnitude. It is also called a spontaneous process.

Features

(a) It takes place without the aid of external agency.

(b) All ireversible processes are spontaneous.

(c) All natural processes are irreversible processes.

(d) Equilibrium is attained at the end of process.

(e)They are real processes and are not hypothetical.

Examples:

G) Flow of heat from a matter at higher temperature to a matter at lower temperature.

(i) Flow of a gas from higher to lower pressure.

ii) Flow of water from higher level to lower level.

iv) Flow of a solvent into a solution through a semipermeable membrane due to osmosis.

(v) Flow of electricity from higher potential terminal to lower potential terminal.

Answer:

The specific heat is the amount of heat per unit MASS required to raise the temperature by one DEGREE Celsius. The RELATIONSHIP between heat and temperature change is usually expressed in the FORM shown below where c is the specific heat. As a result, water plays a very important role in temperature REGULATION.

★ Photons always travel in a straight line.

★ Photons have zero mass and rest energy.

★ Photons have no ELECTRIC charge.

★ Photons are SPIN 1 particles which makes them bosons.

★ They carry energy and momentum which are dependent of frequency.

Answer:

For ISOTHERMAL process,

constant.

So,

constant.

So,

is always greater than 1 as the specific HEAT at constant PRESSURE is always greater than that at the constant volume.

Hence, the slope(steepness to be exact) is more in the case of adiabatic CURVE by the FACTOR of in comparison to isothermal curve.

ANSWER:

Laws of Limiting Friction:

The limiting friction hinges upon the material, the nature of the SURFACES interacting and their evenness. So long as the normal reaction is the same, the MAGNITUDE of limiting friction is free of the shape or the area of the surfaces in contact, for any two given surfaces.

EXPLANATION:

PROVIDED by MASS

Cutoff wavelength = 0.3 micrometer

Explanation:

Given: Photoelectric work function of a METAL surface is 4.14 EV

Find: Cutoff wavelength.

Solution:

W = 4.14 e V

Converting W to JOULES, we get: 4.14 * 1.6 * 10^-19 J

W = H c / λo

Where λo is the cutoff wavelength, h = 6.626 * 10-34, and c is the speed of light in vacuum.

So λo = h c / W

  = 6.626 * 10^-34 * 3 * 10^8 / (4.14  * 1.6 * 10^-19)

  = (6.626 * 3 / 4.14 * 1.6) * 10^-7

  = 3.0009 * 10^-7 m

 = 0.3 micrometer

Cutoff wavelength = 0.3 micrometer
