ve:-VALUE of g on earth's surface. (9.8m/s²)Derivation:-•Mass of earth (Mₑ) = 6×10²⁴kg•Radius of earth (Rₑ) = 6.4×10⁶m•Value of G = 6.67×10⁻¹¹ Nm²/kg²Now,we KNOW that:-=> g = GM/R²Thus,value of g on earth's surface will be:-=>gₑ = GMₑ/R²ₑ=>gₑ = 6.67×10⁻¹¹×6×10²⁴/(6.4×10⁶)²=>gₑ = 6.67×10⁻¹¹×6×10²⁴/6.4×10⁶×6.4×10⁶=>gₑ = (6.67×6)/(6.4×6.4)×10⁻¹¹⁺²⁴⁻⁶⁻⁶=>gₑ = 40.02/40.96×10=>gₑ = 0.98×10=>gₑ = 9.8m/s²Hence,derived !!!Some Extra INFORMATION:-•The value of g at the surface of earth is 9.8m/s² on an average.•The value of g decreases with height.•The value of g decreases with depth.•The value of g is more at poles and less at equator.•The value of g is ZERO at the centre of the earth.

2237484is the ANSWER of the QUESTION

your QUESTION????

In CHEMISTRY, neutralization or neutralisation (see spelling differences) is a chemical reaction in which acid and a base react QUANTITATIVELY with each other. In a reaction in WATER, neutralization results in there being no EXCESS of HYDROGEN or hydroxide ions present in the solution.

Electrostatics is a branch of PHYSICS that studies electric CHARGES at REST. Since classical physics, it has been known that some materials, such as amber, attract lightweight particles after rubbing. The Greek word for amber, ήλεκτρον, or electron, was thus the SOURCE of the word 'electricity'. Explanation:Hope it helps you

The MAGNITUDE of the moment of couple or torque is EQUAL to the product of one of the FORCES and the perpendicular distance between the lines of ACTION of the two forces. The calculation is not linked with the axis of rotation. Hence it is independent of the position of the axis of rotation.Hope it helps  . EXPLANATION:

During change of state (from solid to liquid, GAS to liquid, etc.) the heat energy that is supplied to the substance is used for the change of state and not to increase the kinetic energy of the MOLECULES (that contributes to the temperature of the substance), so the temperature remains constant.Explanation:HOPE IT WILL HELP YOU ☺️HAVE A NICE DAY AHEAD ☺️

tion:If the axis passes through the body's center of mass, the body is said to rotate upon itself, or SPIN. A rotation AROUND an external point, e.g. the planet EARTH around the Sun, is called a revolution or orbital revolution, typically when it is PRODUCED by gravity.

A pulley is a WHEEL on an axle or shaft that is DESIGNED to support movement and change of direction of a taut CABLE or belt, or transfer of power between the shaft and cable or belt. In the case of a pulley supported by a frame or shell that does not transfer power to a shaft, but is USED to guide the cable or exert a force, the supporting shell is called a block, and the pulley may be called a sheave.Explanation:FOLLOW me and mark me brainliest

In PHYSICS, a force is any INTERACTION that, when unopposed, will CHANGE the motion of an object.

d.energy is the ANSWER

When the resultant external torque ACTING on a SYSTEM is zero, the total ANGULAR MOMENTUM of a system is zero, the total angular momentum of a system remains constant.This is the principle of the conservation of angular momentum.

ooooooooooooExplanation:...........

The law of conservation of energy is a law of SCIENCE that states that energy cannot be created or DESTROYED, but only changed from one form into another or transferred from one object to another. This law is TAUGHT in physical science and physics classes in middle schools and high schools, and is used in those classes as well as in chemistry classes.Water can produce ELECTRICITY. Water falls from the sky, converting potential energy to kinetic energy. This energy is then used to rotate the turbine of a generator to produce electricity. In this process, the potential energy of water in a dam can be turned into kinetic energy which can then become electric energy. When playing pool, the cue ball is shot at a stationary 8 ball. The cue ball has energy. When the cue ball hits the 8 ball, the energy transfers from the cue ball to the 8 ball, SENDING the 8 ball into motion. The cue ball loses energy because the energy it had has been transferred to the 8 ball, so the cue ball slows down. Explanation:

tion:The angle α which the RESULTANT R makes with A is GIVEN bytanα= A+BcosθBsinθ or COS(θ/2)sin(θ/2) = A+Bcosθ2Bsin(θ/2)cos(θ/2) which gives A+Bcosθ=2Bcos 2 ( 2θ )or A+B[2COS 2 ( 2θ )−1]=2Bcos 2 ( 2θ )A=B.thank you for question

tion:It is FOUND that whenever a current carrying conductor is placed INSIDE a MAGNETIC field, a force acts on the conductor, in a direction perpendicular to both the directions of the current and the magnetic field. While current flows through a conductor, one magnetic field is induced AROUND it.
