75 cmExplanation:GIVEN,Focal LENGTH, f=50cmMagnification, m=2m= uv =2v=2uFrom mirror FORMULA,F1 = v1 + u1 f1 = 2u1 + u1u= 23f= 23×50 =75 cmObject Is placed at 75cm from the mirror

the ANSWER that. 3 /4 = 0.75

Explanation:Density is the only thing affecting WHETHER something FLOATS or sinks. If an object has a HIGHER density than the fluid it is in (fluid can mean liquid or gas), it will sink. If it has a lower density, it will float. Density is determined by an object's mass and volume.plz LIKE my answer

distance / time = 54 KM / (3/2) hr = 54*2 / 3 = 18*2 = 36kmph . A BUS travels 54 km in 90 minutes. the speed of the bus is 36 KMPH.

ced CHEMICAL equation gives the IDENTITY of the REACTANTS and the PRODUCTS as well as the accurate number of molecules or moles of each that are CONSUMED or produced.❤

As such, all objects free FALL at the same rate REGARDLESS of their mass. Because the 9.8 N/kg gravitational field at EARTH's surface CAUSES a 9.8 m/s/s acceleration of any object PLACED there, we often call this ratio the acceleration of gravity.

caliper is an INSTRUMENT used to MEASURE the internal and external diameters of SMALL tubes.The least count is the finest MEASUREMENT you can take with the help of that vernier calipers.So least count= 1 MSD-1VSDHere 10 vsd=9 msd1 vsd=.9 msdFrom above LC= 1MSD-1VSDLC=1MSD-.9MSD=.1MSD(which is equal to .1 MM).Least count =.1 mm

Scalar quantity is DEFINED as the physical quantity with magnitude and no direction.Some physical QUANTITIES can be described just by their numerical value (with their respective UNITS) without directions (they don’t have any direction). The ADDITION of these physical quantities follows the simple rules of the algebra. Here, only their magnitudes are added.If it helps uh do mark me as BRAINLIST..thank u !!

tion:They are OFTEN water-based. Examples of naturally occurring polymers are SILK, wool, DNA, cellulose and proteins. In our previous section on network polymers, we MENTIONED vulcanized rubber and PECTIN. Vulcanized rubber is a synthetic (man-made) polymer, while pectin is an example of a natural polymer.

ff's Current Law (KCL) is KIRCHHOFF's first law that DEALS with the conservation of CHARGE entering and leaving a junction. ... His current law states that for a parallel path the total current entering a circuits junction is exactly EQUAL to the total current leaving the same junction.

There is not one, not two, not EVEN three gravity equations, but many! The one most people know describes NEWTON's universal law of gravitation: F = Gm1m2/r2, where F is the force due to gravity, between two masses (m1 and m2), which are a DISTANCE r apart; G is the GRAVITATIONAL constant.

y core contains a variety of blood vessels, and the bulk of blood concentrates there in the NORM. Hence, heat transfer in it is MAINLY convective. In surface tissues, where the rate of blood circulation is lower and the VASCULATURE has certain specific features, heat transfer is mainly conductive

tion:Answer: EXPLANATION: As you can see in the FIGURE the FORCE with which be gold ingot presses against the ground in this situation is just its normal force is the force pushing the two SURFACES together and the stronger the normal force the stronger the force due to friction hope it HELPED u!!

tential gradient of a WIRE depends upon the following FACTORS: (i) K∝I (i.e., CURRENT passing through the potentiometer wire) (ii) K∝ρ (i.e., specific resistance of the material of the potentiometer wire) (III) K∝1A, where A is the area of cross-section of the potentiometer wire. 4:35.

ntage is a way of expressing a number as a fraction of 100 (per cent meaning “per hundred”). It is denoted using percent sign, “%”. This concept is USEFUL for comparison of fractions as all the fractions are indexed to 100 when converted to PERCENTAGES. Any percentage can be expressed as a fraction or a decimal fraction and vice versa.For example, fractions such as 2/5 can be written as 0.8 or 80% and vice versa. Percentage Value = Fractional Value x 100 Important Percentages Formulas & ConceptsHere are some very important Percentages formulas and concepts to solve various percentages BASED problems. 1) Percentages Formulas for Percentage increase or decreasePercentage increase or decrease of a quantity is the percent representation of the ratio of the actual (absolute) increase and decrease to the original quantity.percentages formulas for percentage increase decreaseExample: If the price of an idly is increased from Rs. 25 to Rs. 35, the percentage increase in the price can be computed as Percentage change = (10/25)*100 = 40% 2) Percentages Formulas for MULTIPLICATION FactorWhenever there is any percentage increase or decrease in a quantity, instead of calculating the actual increase/decrease and then adding to/subtracting from the original quantity, we can directly compute the NEW quantity by using the concept of the multiplication factor.For every percentage increase or decrease, a number called multiplication factor can be calculated which when multiplied by the original quantity will give the increased quantity.Mark me as brainlist__"__"__!!!!!!
