cle of mass 10 g moves along a circle of RADIUS 6.4 cm with a constant tangential acceleration. What is the MAGNITUDE of this acceleration if the kinetic energy of the particle becomes equal to 8 X 10^-4 J by the end of the second revolution after the beginning of the MOTION?kinetic energy = 8 × 10^-4 Jor, 1/2 mv² = 8 × 10^-4 or, 1/2 × 10 × 10^-3 v² = 8 × 10^-4 or, v² = 16 × 10^-2 => V = 0.4 m/s initial velocity of particle, u = 0 m/s we have to find Tangential acceleration at the end of 2nd revolution. total distance covered, s = 2(2πr) = 4πr so, v² = 2as a = v²/2s = (0.4)²/2(4πr) = 16 × 10^-2/(8 × 3.14 × 6.4 × 10^-2) = 0.0995 m/s² ≈ 0.1 m/s²

nd...*_*All living organism need some method of MOVING substances from one part of the body to other parts of the body. For example, in living organisms food and oxygen are moved in the body to all the cells and waste materials such as carbon DIOXIDE is taken away from them. The system of moving substances in different parts of body is called transport system. In plants, food and water are transported by bundles of tubes present in STEM called phloem and xylem. In animals, food, water and respiratory gases (oxygen and carbon dioxide) and other substances are transported by blood.       In plants, transport system is not COMPLICATED as in animals. The transport system in plants consists of bundles of tubes in the stem, branches and roots. These tubes are called xylem and phloem. The main function of xylem is to transport water and dissolved minerals from the roots to rest of the plant body. While, the phloem transports the food manufactured in the leaves to all parts of the plant. hope its help U...my frnd*_*

our answer is here.A stone is thrown vertically upwards it come down after reaching a particular height because that the Earth attracts object towards it is due to the GRAVITATIONAL force . Objects Falls towards the earth under this force alone, we say that the objects free fall .while falling there is no changes in the direction of motion of the object . But due to the earth's attraction , there will be a change in the magnitude of the velocity . Any change in velocity involves acceleration . Whenever and objects Falls towards the earth, an acceleration is involved. This acceleration is due to the earth's gravitational force. Therefore, this acceleration is called the acceleration due to the gravitational force of the earth . It is denoted by g unit of g is the same as that of acceleration, that is , metre per second square .I hope it is useful for you ,and I THINK you understand .Then; please mark me BRAIN list .And FALLOW me .

!!! friction is a force which oppose the motion . or ( as per standard 9 ) friction is type of contact force which act between the TWO Bodies to oppose the motion in contact . as per class 11 th friction have two type 1 ) static friction :- friction which are self adjusting . ( in simple WORD ) 2) kinetic friction :- friction which act in moving body is called kinetic friction . force of friction is GIVEN by F = μN where μ is coffecient of friction . and N is Normal act on body . hope it helps you dear !!! thanks !!

e¡!!Here is the answer==================In REFRACTIVE index, MAIN point is that.. Light passes through LIGHTER MEDIUM to the denser ones... and the optical density refers to "the degree to which a refractive medium RETARDS transmitted rays of light."From this, we may concluded that, If the refractive index is more, more is the optical density

e!!! The TWO CONDITIONS for the body to remain at rest are(1). All the externally applied FORCES were cancelled out.. (2). the externally applied force is not exceeded the LIMITING friction...

anding wave, the wave does not move, but there is an oscillation at EVERY point. A standing wave can be obtained by a SUPERPOSITION of a left- and right-moving travelling wave. An other WAY of obtaining a standing wave is to contain it in a finite region such as requiring the the AMPLITUDE be 0 at both ENDS.

ircuit, also called a resonant circuit, is an ELECTRIC circuit consisting of an inductor(L) and a capacitor (C), connected together. The electric current and the charge in the capacitor in the circuit UNDERGO electrical LC oscillations when a charged capacitor is connected to an inductor. The electrical energy stored in the capacitor is its initial charge (qm). It is expressed as follows: Ue =1/2( qm)^2/C/.The inductor contains zero energy, and the charge varies sinusoidally with time. When the switch is turned on the current in the circuit starts to increase and the charge in the capacitor keeps decreasing, The current in the circuit induces a magnetic field in the inductor. When the current increases to its maximum level (Im) the magnetic energy in the circuit is represented as: Ub = 1/2*L*(Im)^2.The magnetic field starts decreasing because there is no further change in current in the inductor. Then the current is induced in the circuit as a result of the decreasing magnetic field. With reverse polarization current starts charging the capacitor. The process is repeated again once the capacitor is fully charged, The energy in the WHOLE SYSTEM thus oscillates between the capacitor and the inductor. The charge oscillates with a natural frequency of w(o) = 1/(LC)^1/2.In PRACTICE this process is never achieved at its maximum level due to loss of energy in the form of heat from the resistance and also energy loss due to radiation of electromagnetic waves.

nergy or solar energy is the main  factor responsible for the formation of WIND  and wind energy.Air moves from high pressure region to low pressure region. Due to uneven HEATING on earth we have land and sea breeze. So, WARM air expands and cooler air fills the gap.Hence wind is created. The kinetic energy possessed by the air due to its velocity is called wind energy.Due solar energy, land breeze and sea breeze are caused. Hence, Wind energy is a TRANSFORMED FORM of Sun's Energy.

error (percentage error) is the difference between an EXPERIMENTAL and theoretical value, divided by the theoretical value, MULTIPLIED by 100 to give a percent. In some fields, percent error is ALWAYS expressed as a POSITIVE number. In other fields, it is correct to have either a positive or negative value.
