ue of acceleration due to gravity at a height from the surface of the earth of radius is,But if HENCE we know that,Taking Thus (1) BECOMES, Then percentage decrease in the VALUE of acceleration due to gravity is,We know that, weight of a body,Hence percentage change in weight will be,Since mass of body REMAINS CONSTANT, Then,From (3),According to the question,Hence,Hence the percentage decrease is Negative sign indicates the decrease in the value.

So, you know that you're dealing with two particles, one at the top of a tower that's h meters high, and the other one on the bottom.Moreover, you know that if you drop the top particle with no initial velocity and launch the bottom particle with an initial velocity equalto V0, they meet when the UPPER particle travelled 1/n of the heigt of the tower.For the upper particle, the DISTANCE it travelled can be written as1/n*h = v0upper = 0*t+1/2*g*t^21/n*h = 1/2*g*t^2  ---------------------------(1), wheret - the time needed for the particle to reach that height.The bottom particle will travel a distance of:h−1/n*h = (n−1)/n*hFor the bottom particle you can write(n−1)/n*h = v0*t−1/2*g*t^2----------------------------(2)Since the two particles meet up at this point, the time of FLIGHT for both particles must be equal.Use EQUATION (1) to find a relationship for t^2t^2 = 2h/ngPutting this into equation (2) to get(n−1)/n*h = v0*√2h/ng−1/2 * g * 2h/ng(n−1)/n*h = v0*√2h/ng − h/nRearrange to isolate v0 on one side of the equationv0*√2h/ng = (n−1)/n*h + h/nv0*√2h/ng = n/n * h − h/n + h/nv0 = h / √2h/ng = h * √2h/ng / 2h/ng     = ng/2 * √2h/ngThis is equivalent tov0 = ⎷n^2*g^2/4 * 2h/(n*g)v0 = √ngh/2Explanation:

15,000 rpm15,000 rpmThere are many types of jet engines with one or more SHAFTS ROTATING coaxially in each other and these shaft are rotating at different speeds with the lowest being the onw that drives the large FAN in front. The smaller bladed discs inside the core RUN much FASTER. 2,500 up to 15,000 rpm.

Explanation:Here is..Solution :Given that magnification = 100Average WIDTH of the HAIR in the field of VIEW of the microscope is 3.5 mmActual estimate  THICKNESS of hair = AVERAGE width on field of view / magnification                                                                   =3.5 mm / 100  = 0.035 mmAnswer:  estimate on the thickness of hair = 0.035 mm Mark me brainliest

ist starts from REST and ATTAINS a velocity of 50m/s in 10 SEC its acceleration isu = INITIAL velocity = 0m/sv = final velocity = 50m/st = time taken = 10seca = (50 - 0)/10 m/s²a = 50/10 m/s² a = 5 m/s²

Explanation:Hello Friend,ANSWER RELATIVE velocity of a particle P in the frame of Q changes linearly with time during the flight of P Acceleration of Particle P and Q along the inclined is same Acceleration of particle P PERPENDICULAR to the incline PLANE =10 COS60                                                                                                     =10 × 1/2                                                                                                    =5 m/sec  squareSoV p −5(2)=0V p  = 10 m /sHence speed of projection of P is 10 m/sec.

Solids of conductor-)When the ELECTRONS pass from valance BAND to the conduction band these solids conduct electricity with FLOW of charges in the FORM of electrons. In Conductors this energy gap is extended and the valance band and the conduction band overlap each other. This makes it easy for the electricity to pass through them.insulator BASED on kronig i don't know

Experimental data in science and ENGINEERING is data produced by a measurement, test METHOD, experimental design or quasi-experimental design. ... Experimental data MAY be qualitative or quantitative, each being appropriate for DIFFERENT investigations.

Magnetic permeability μ (Greek mu) is thus DEFINED as μ = B/H. Magnetic flux density B is a MEASURE of the actual magnetic field within a material considered as a CONCENTRATION of magnetic field lines, or flux, per unit cross-sectional area.

Explanation:Question 11. Potassium chlorate (KCIO3) on heating forms potassium chloride and oxygen. Write a BALANCED equation for this reactionThanks it is a brilliant questionQ1. 2KCLO3 -----∆----> 2KCL + 3O2. Q2. 2 MG + CO2 = 2MGO + C. In the above question it is based on molar concept because there is BALANCING equation balancing equation is based on the molar mass because no one after and before reaction molar masses change that's why the molar mass ICD container in that so we should to be maintained this formula and keep balancing the EQUATIONS help you★ HOPE IT WILL HELP YOU ★ Please mark me as brain LIST  BY Tolety Roshan
