tion:Why sand? The MAIN purpose of adding sand in concrete is to minimise the segregation of concrete and to FILL out the pores between the cement and COARSE aggregate. This test (bulking of sand or bulking of fine aggregate) is to ENSURE that we are using the right AMOUNT of sand while concreting

For electric CURRENT, the directionality is only that along the wire (opposite to FLOW of electrons). In Summary, since the electric current doesn't follow the Triangular LAW, it is not a VECTOR. It is just a scalar quantity. [Another such quantity is TIME.

positively charged PARTICLES are 0.03 m APART. The first PARTICLE has a charge of 8.1 C, and the second a charge of 2.6 C. Which change would INCREASE the electric force between the two particles

y here is your answer The dimensionless REYNOLDS number plays a PROMINENT role in foreseeing the patterns in a fluid's BEHAVIOR. The Reynolds number, REFERRED to as Re, is USED to determine whether the fluid flow is laminar or turbulent.hope it helps #chocolatey❤

h the cars A and B meet at C which is at kilometres away from initial position of car B, after time seconds. The car B moves with speed of WITHOUT acceleration.By SECOND equation of motion, DISPLACEMENT of car B will be,The car A moves with speed of but has an acceleration of By second equation of motion, displacement of car A will be,Subtracting (1) from (2),Then (1) becomes,Hence 5 km is the ANSWER.

The POINT is that for the same amount of WORK, power and time are INVERSELY proportional. The power equation SUGGESTS that a more powerful engine can do the same amount of work in less time. A person is also a machine that has a power rating.

Significant figures are the actual values that we USE to answer. ... Also, we COUNT the digits of the number starting from first non-zero DIGIT , in the case of significant figures. ORDER of magnitude, on the other hand, is an exponential change in the POWER of 10 in the value of a quantity.

Newton's second LAW states that the acceleration of an OBJECT is directly related to the net force and inversely related to its mass. Acceleration of an object DEPENDS on two THINGS, force and massExplanation:here is your answer if you like my answer PLEASE follow

If a zero is found between SIGNIFICANT digits, it is significant. Zeros can be used as (insignificant) PLACE HOLDERS to the LEFT of significant digits if the number is a decimal.

I THINK OPTION 2 is RIGHT

ac currentExplanation:Alternating CURRENT (AC) is an electric current which periodically REVERSES direction and changes its MAGNITUDE continuously with time in contrast to direct current (DC) which FLOWS only in one direction.

This is the real answerExplanation:VIDYUT is an Indian masculine/feminine given NAME. The SANSKRIT word which is a feminine word has SEVERAL meanings INCLUDING "shining, glittering ", " lightning" and "the dawn

n IDEAL (BASELINE) physical constant. Its CODATA value is: ε0 = 8.8541878128(13)×10^-12F⋅m−1 (FARADS PER meter), with a relative uncertainty of 1.5×10^−10.

esign of the flag of INDIA that was first presented in 1921 to Mahatma Gandhi, leader of the All-India Congress, was created by Pingali Venkayya. It consisted of the colours associated with the two principal religions, RED for Hindus and green for Muslims.★ ADDITIONAL INFORMATION★ The flag of India is composed of three horizontal stripes. The top stripe is a deep saffron colour, the middle is white, and the bottom is green. In the centre of the white stripe is a 24-spoked BLUE chakrAnswer with Quality :)

Explanation:GIVEN , ∅=60°Let the tow unit VECTOR a and band their magnitude are |a| & |B| respectively.∴ their vector product will be                   a×b= |a|.|b|.sin∅                         =   1 .  1 .sin60°                         =    √3/2                                         Answer.

i dont know man u can HANDLE this xD ac currentExplanation:Alternating current (AC) is an electric current which periodically reverses direction and changes its magnitude CONTINUOUSLY with time in contrast to DIRECT current (DC) which flows only in ONE direction.

here is your ANSWEREXPLANATION:i HOPE it will HELP you...

When two light waves from different coherent sources meet together, then the distribution of energy due to one WAVE is disturbed by the other. This modification in the distribution of light energy due to super- position of two light waves is called 'Interference of light'.The path difference of light from the sources S 1 and S 2 meeting at point P which is at a distance y above the CENTRAL axis is Dyd Hence for constructive interference, Dyd =nλTherefore bright fringes occur at y=0, dDλ , d2Dλ ,....THEREFORE the fringe width= dDλ......... please MARK me as BRAINLIEST

Input voltage = 240VRatio of the NUMBER of TURNS in secondary to the primary coil = 3 : 2TO Find :Output voltage.Solution :❖ The voltage and currents in a transformer are related as» For a step-up transformer, k > 1 and for a step-down transformer, k < 1Given that, By substituting the given values;Knowledge BoosteR :A transformer is essentially an a.c. device. It can't work on d.c. It changes alternating voltages/currents. It doesn't affect the frequency of a.c.The small transformers are self-cooled, which transfer heat directly to the surrounding. Large transformers are cooled by placing them in oil tanks to prevent overheating.

A SCALAR quantity is DEFINED as the physical quantity that has only magnitude, for example, mass and electric charge. On the other hand, a vector quantity is defined as the physical quantity that has both magnitude as well as direction LIKE force and WEIGHT.

tion: At the maximum height its veloicity be zero because we KNOW that EARTH is ATTRACTING the body downwards

An imaginary line that passes through the OPTICAL center and the center of curvature of both faces of the LENS, and is PERPENDICULAR to the faces is KNOWN as the principal axis. Focus is a point on the principal axis where all the rays that are parallel to the principal axis meet after REFRACTION from the lens.

:-There are TWO TYPES of CHEMICAL EQUILIBRIUM:-HOMOGENEOUS Equilibrium.Heterogeneous Equilibrium.

tion:Longitudinal wavesThere are two types of WAVES: Longitudinal waves and Transverse waves. Longitudinal Waves: A wave in which the particles of the medium vibrate back and FORTH in the 'same DIRECTION' in which the wave is moving. Medium can be solid, liquid or gases. THEREFORE, sound waves are longitudinal waves.

Electric Current is the flow of electrons through a wire or solution. In a solid the electrons are passed from one POSITIVELY CHARGED METALLIC atom to next but in solution the electron is carried by the ions present in the solution. A solution capable of carrying CHARGE is called an electrolyte.
