bhai। SPEED KARTI H!!!!!!

(a) V1 = ve = veExplaination:Velocity of body doesn't depend on the mass of body.It only DEPENDS on the height of free fall.Velocity with which the object reaches the ground  v = 2ghFor all THREE masses, height is same and hence velocity at ground level will be same. ⟹ v1 : v2 : V3 = 1 : 1 : 1⟹ v1 = ve = ve {OPTION (a)}

(1) when three RESISTANCES each of value r Ohms are connected in series, their equipment resistance becomes r+r+r=3R Ohms(2) when three resistances each of value r Ohms are connected in parallel , their equipment resistances becomes r/3 Ohms(3) RATIO of resistances in series to parallel connection, Rs/Rp = 3r/r÷3 = 3r ×3/r =9

Refraction of waves INVOLVES a CHANGE in the direction of waves as they pass from one medium to ANOTHER. Refraction, or the bending of the path of the waves, is ACCOMPANIED by a change in speed and wavelength of the waves. ... Thus, if water waves are PASSING from deep water into shallow water, they will slow down.

Hey Mate! Here is your answer.Explanation:The theory of LIGHT being a particle completely VANISHED until the end of the 19th century when Albert Einstein revived it. Now that the dual nature of light as "both a particle and a wave" has been proved, its essential theory was further evolved from electromagnetics into quantum mechanics. Einstein believed light is a particle (photon) and the flow of photons is a wave. The main point of Einstein's light quantum theory is that light's energy is RELATED to its oscillation frequency. He maintained that photons have energy equal to "Planck's constant times oscillation frequency," and this photon energy is the height of the oscillation frequency while the intensity of light is the quantity of photons. The various properties of light, which is a type of electromagnetic wave, are DUE to the behavior of extremely small PARTICLES called photons that are invisible to the naked eye.

Because the density of GOLD is CONSTANT. Density is constant for whatever shape you'll build.Explanation:Not only RING or brick, it doesn't matter what shape you MAKE, all will have same density.Because, you USED the same material, which has it's constant density.

a)diffusion is faster at higher temperatures because the GAS MOLECULES have greater kinetic energy.b)Carbon dioxide and OXYGEN are the TWO gases of air which dissolves in WATER by diffusion.the oxygen is dissolved in water so that fishes can take in oxygen through water to breathe ,this is the biological importance of this process in nature

Yes, I agree with the statement that ENERGY from VARIOUS SOURCES is considered to have been derived from the Sun. Sun is the ultimate source of energy. All forms of energy are DIRECTLY or indirectly derived from the solar energy.

As the temperature of the semi-conductor is increased, the ELECTRONS in the valence band gain sufficient energy to escape from the confines of their ATOMS. As a RESULT, in higher TEMPERATURES, a semi-conductor's valence electrons are FREE = conduction results, resistivity decreases. ✔✔HOPE ITS HELP FOR YOU ✌✔

tion:Conclusion that we get from fact that when an OBJECT is PLACED in the path of LIGHT a shadow is formed behind the object is that light always travel in straight line and light rays are NEVER DEVIATED from this straight line and do not show any bending...

Explanation:Gravitational force- F\; = \frac{G\, m_{1}\, m_{2}}{r^{2}} Acceleration due to gravity (g) g=\frac{GM}{R^{2}} Variation in 'g' with HEIGHT g'\alpha\, \frac{1}{r^{2}} r=R+h Variation in 'g' with depth GRAVITATION- FORMULA- Variation in Acceleration due to gravity with depth g'\alpha (R-d) g'=g\left [ 1-\frac{d}{R} \right ]

Well if by NORTH and south you mean up and down, a ball thrown upwards is the answer. It has an upwards VELOCITY and since the earth is pulling it down, the ACCELERATION is towards the ground, i.e., a NEGATIVE acceleration.Explanation:FOLLOW me..

I HOPE U will understandplz ADD to BRAIN LEAST

its VELOCITY and ACCELERATION

s enjoy Anonymous questions concerning a "body", I know it's an expression, but wish the folks would say "OBJECT". In this case, I am forced to imagine a guy who did something bad to my daughter, now tied to a rope in my HAND, and being forced with a WHIP (in my other hand) to run in a circle of whatever radius I decide (R?).To answer, he will stop when I tell him to. If it's where I first suggested he START running, his displacement and distance from that point will be ZERO.Same thing as a weight tied to a string; no VELOCITY or speed computation...

here's the ANSWER PLEASE FOLLOW me

1stanswer 1. (a) SCALARS are quantities that are fully described by a magnitude (or numerical value) alone.(b) Vectors are quantities that are fully described by both a magnitude and a direction. answer 2. as object equal DISTANCE in equal interval of time it is said to be uniform motion whereas if a body covers unequal distance in equal interval of time or an equal distance in unequal interval of time it is said to be non uniform motionanswer 3.yes in object which has moved through a distance can have zero displacement example when a person walking along a circular PATH return back to the starting point after completing a circle his displacement is zero but he covers a distance to payaar where r is the radius of circular path the displacement is zero is the shortest distance between the initial and final position of the person is zero.answer4. 1. speed is the rate of CHANGE of distance between velocity is the rate of change of displacement in a specified direction 2.speed is a scalar quantity but velocity is a vector quantityanswer5. speed =distance /time =200m/25sec =8m/sec answer6. velocity=displacement /time =150m/10sec=15m/secpicture 2ndanswer1. when a body is moving it is said to be in motion .ex. a moving car answer2. when a body stay at a place or said to be as not moving it is said to be at REST .ex. electrical poleanswer3 . refrence point or origin is tge point from where a body starts moving .answer4. distance - it is defined as the actual path covered by a body . it is a scalar quantity full stop it can never be negative or zero. distance can be equal to or greater than displacement displacement - it is the shortest distance between two points by between which the body moves it is a vector quantity. it can be negative zero positive positive displacement can be equal to or less than displacement answer5. i) A body moving in a straight line path can have displacement and distance equalii) when a person walking along a circle pass returns back to the starting point after completing a circle is displacement is zero but he covers the distance to payaar where r is the radius of the circular path the displacement is zero as the shortest distance between the initial and final position of person ishere are your answers høpê ít hêlp yøú plzz mårk ås ßràíñlíést plzzz følløw mē
