, magnification is the ratio of height of image to height of object. here it is given that, LINEAR magnification PRODUCED by a spherical mirror is + 1/3 e.g., height of image/height of object = 1/3 height of image = 1/3 × height of object it is clear that, height of image is one third of height of object. it is POSSIBLE only when mirror is convex mirror. because in case of concave mirror, magnification will be positive and GREATER than 1 . image formed by mirror is virtual , erect and diminishedthe image formed by mirror is shown in ray diagram.

and V=220vI = P/V = 100/220=5/11=0.45ASo,R= V/I= 220×11/5=44×11=484 OHM

there are two positively CHARGED bodies having masses m1 and m2 they will SHOW a gravitational FORCE of ATTRACTION. they'll also show repulsion as they are both positively charged. remember electrostatic force of repulsion will be more than gravitational force of attraction.if you find it helpful please mark it as brainliest.

+R2+R3 is the REQUIRED FORMULA

0°C has a total latent heat ofQ=m*L = 540*80 = 43200 cal.Now for water to come at 0°C and it's state to REMAIN as water, we need to remove heat from it which is given by,Q= m*Cp*(∆T) = 540* 1* 80 = 43200 cal.So, we can see thatHeat released by water to reach from 80°C to 0°C = heat REQUIRED by ICE to melt into water at 0°C.So, the ice will melt to water and it's temperature will be 0°C.Hence, the final state would be water at 0°C.So, the answer is A.Hope this help you.

re the OPTIONS ?FOLLOW me

n reason for refraction of light is DUE to the reason that when light travels from one MEDIUM to another the velocity of the light wave changes due to change in wavelength of light wave. So since velocity of the light is not same in EVERY medium the path of light changesPlease mark as brain LIST PLEASE

case the angle of refraction is greater than angle of INCIDENCE. When light rays travel from glass into air or from WATER into air they bend away from the NORMAL. The speed of light rays increase while TRAVELLING from glass or water into air. In this case refraction of light takes placetwo timesPlease mark as brain list please please please

is the twisting force that tends to cause rotation. The POINT where the object rotates is known as the axis of rotation. MATHEMATICALLY, torque can be written as T = F * r * sin(theta), and it has UNITS of Newton-meterPlease mark as brain list PLEASE

er is kept in glasses. the water is UNEQUAL in all the glasses. and as there is change in medium between SOURCE and PROPAGATION of SOUND, it PRODUCES different sounds

omplete QUESTION

that g = GM/r²When we go inside the earth, towards the centre, the R decreases, HENCE, r² would also decease. THUS, the acceleration due to gravity should increase as it is INVERSELY proportional. But this is not the case. When we move towards the centre of earth, the mass of earth above is EXCLUDED. Hence, the mass required for g decreases, so the value of g also decreases.

house potential difference : 240 VCurrent : 5 - 20 AThis means the line wires that are entering the meter have a potential difference of 240 V The minimum and maximum LIMIT of current that can be drawn from the mains is 5 - 20 A.When the current drawn from mains is more than 20A. Overheating OCCURS and MAY CAUSE a fire. This is called overloading.

all INTEX Question From NCERTThey are EASY and SUPER IMPORTANT for board.Hope it'll HELP You........

:Hey Mate,GIVEN,Man SPEED with CURRENT = 15 km/hrSpeed of the current = 2.5 km/hr=> Speed of a man + Speed of the current = Man speed with current=> Speed of a man + Speed of the current = 15 km/hr=> Speed of a man = 15 -  Speed of the current=> Speed of a man = 15 -  2.5=> Speed of the man = 15 - 2.5 = 12.5 km/hrMan speed against the current = Speed of the man - Speed of the currentMan speed against the current =  12.5 - 2.5 = 10 km/hr#Error : QUESTION PASTE twice.

all light waves move through a vacuum at the same speed, the number of wave crests passing by a given POINT in ONE second DEPENDS on the wavelength. ... The equation that relates wavelength and frequency for ELECTROMAGNETIC waves is: λν=c where λ is the wavelength, ν is the frequencyand c is the speed of light.

ill move the screen away from the lens. because nearer the object comes to the lens the father the image goes2.the size of image increases as more the object NEAR to the lens more the enlarged in image3.if he Moves the candle very CLOSE to the lens as near as the object distance is less than the focal length there will be no image on screen because now the image formed is VIRTUAL and not REAL. (LAST case of convex lens when object is between O and F)

of coating IRON and STEEL ARTICLES with ZINC is called Galvanization. HOPE it helps uhh❤❤❤

olic (or paraboloid or paraboloidal) reflector (or DISH or mirror) is a REFLECTIVE surface used to collect or project ENERGY such as light, sound, or RADIO WAVES. Its shape is part of a circular paraboloid, that is, the surface generated by a parabola revolving around its axis.

ost zone of flame is the HOTTEST as compared to the INNER most and the MIDDLE zone. Hence, goldsmiths use the OUTERMOST zone of the flame for MELTING gold and silver. Hope it helps uhh❤❤❤

F/m ,a=12/3=4m/s^2

are LESS polluting.2)they are EASY to TRANSPORT.

vin–Planck statement (or the heat ENGINE statement) of the second law of thermodynamics states that it is impossible to devise a cyclically OPERATING device, the sole effect of which is to absorb energy in the FORM of heat from a single thermal RESERVOIR and to deliver an EQUIVALENT amount of work.

this HELPS you!!❤️❤️

rk BRAINLIEST plse HOPE it helped U

it HELP you if YES GIVE brainli
