ctional force between two bodies depends mainly on THREE factors: (I) the adhesion between BODY SURFACES (ii) ROUGHNESS of the surface (iii) deformation of bodies.

bvExplanation:

A CELL is a MASS of cytoplasm that is bound externally by a cell membrane. USUALLY microscopic in SIZE, cells are the smallest structural units of living MATTER and compose all living things. Most cells have one or more nuclei and other organelles that carry out a variety of tasks.

m:it DEFINES the AMOUNT of force applies for a interval of time.force is responsible for changing the Momentum of an object. Solution:-- negative implies the opposite IMPACT of force with respect to motion.★ 64 N of AVERAGE force is applied by the player.

an instrument for measuring an electromotive force by balancing it against the potential DIFFERENCE produced by passing a known CURRENT through a known VARIABLE resistance.Explanation:A potentiometer (also known as a pot or potmeter) is defined as a 3 terminal variable resistor in which the resistance is manually VARIED to control the flow of electric current. A potentiometer acts as an adjustable VOLTAGE divider.

For a cell, a graph is plotted between the POTENTIAL difference V across the terminals of the cell and the current I drawn from the cell (SEE Figure). The emf and the internal resistance of the cell are E and r, respectively. Then :157607

Steroids are a man-made VERSION of chemicals, known as HORMONES, that are made NATURALLY in the human body. Steroids are designed to act like these hormones to reduce inflammation. They're ALSO known as corticosteroids, and are different to anabolic steroids used by bodybuilders and athletes.

) Roxanne experiments with different liquids from the table. She has two identical beakers and puts one LITRE of water into each of them. She puts one litre of OIL into BEAKER A. The oil floats on the water because of their densities. Roxanne puts one litre of ANOTHER of the liquids into beaker B. The liquids do not mix together. Look at the diagrams. (i) Which beaker of liquids is heavier, A or B?Ans - B is heavier

Mass, in physics, QUANTITATIVE MEASURE of inertia, a fundamental PROPERTY of all matter. It is, in effect, the resistance that a body of matter offers to a change in its speed or position UPON the application of a force. The greater the mass of a body, the smaller the change produced by an applied force.

a fundamental PROPERTY of matter. It is a combination of the TOTAL NUMBER of ATOMS, the density of the atoms, and the type of atoms in an OBJECT.

Check this answerExplanation:(a) Principle:  It works on the principle of FARADAY’s law of electromagnetic induction. Whenever a coil is rotated in a uniform magnetic field about an axis perpendicular to the field, the magnetic flux linked with coil changes and an INDUCED emf is set up across its ends. Working:  When the coil STARTS rotating with the arm AB moving up and the arm CD moving down, cutting the magnetic lines of force, then according to Fleming's right-hand rule and the induced current is set up in these arms along the direction of AB and CD. So an effective induced current flowing in the direction of ABCD is OBTAINED.   If there are large number of turns in the coil, the current generated in each turn adds upto give a large quantity of current through the coil.   After half rotation of the coil, its arm CD starts moving up and AB moving down. As a result, the direction of the induced currents gets reversed in the coil in the direction of DCBA. Thus after every half rotation the polarity of the current in the respective arm changes. Such a current, which changes its direction after equal intervals of time, is called to get a direct current a split ring type commutator must be used in place of slip ring commutator.   emf induced in a coil   Consider a coil of N turns and area A being rotated at a constant angular velocity ω in a magnetic field of flux density B, its axis being perpendicular to the field.  When the normal to the coil is at an angle θ to the field, the flux through the coil is BAN cosθ = BAN cos(ω)t, since θ = ωt.E=− dt /dϕ ​E=−  dt /d(BANcosθ) ​ E=BANωsin(ωt) The maximum value of the e.m.f (E  o ​ ) is when θ (= ωt) = 90o (that is, the coil is in the plane of the field as shown in Figure 2) and is given by E  o ​ =BANω B.

tion:Newton's second law of motion states that the acceleration of a SYSTEM is directly proportional to and in the same direction as the NET EXTERNAL force acting on the system, and INVERSELY proportional to its MASS. In equation form, Newton's second law of motion is a=Fnetm a = F net m .

what is this?EXPLANATION:is it a LINK or SOMETHING?

net Δ t . F net Δ t F net Δ t is known as impulse and this EQUATION is known as the impulse-momentum THEOREM. From the equation, we see that the impulse equals the average net external force MULTIPLIED by the time this force acts. It is equal to the change in momentum.Impulse = force x TIMEPLEASE mark me brain mark LIST

Before getting started with the experiment, it is important to understand a few terms that are used in a concave mirror and convex lens:Centre of curvature: For a curved mirror, the centre of curvature, C can be defined as the centre of a hollow glass sphere of which a curved mirror is a part.Radius of curvature: For a curved mirror, the radius of curvature, R can be defined as the radius of the hollow glass sphere of a spherical mirror is part.Principal axis: Principal axis is defined as the imaginary line passing through the pole and centre of curvature of the spherical mirror.Principal focus: Principal focus is defined as a point at which the reflected rays meet or appear to meet for the spherical mirror. For a concave mirror, the principal focus is in the front and for a convex mirror, the principal focus is at the behind.Below is an experiment to determine the focal LENGTH of a concave mirror and convex lens.AimTo determine the focal length of:Concave mirrorConvex lens by obtaining the image of a distant object.TheoryHow to find focal length of concave mirror?Following are the ways to obtain the focal length of the concave mirror:A concave mirror is defined as the spherical mirror whose reflecting SURFACE is curved inwards and follows laws of reflection of light.The light rays coming from a distant object can be considered to be parallel to each other.If the image formed is REAL, inverted and very small in size, then the parallel rays of light meet the point in the front of the mirror.The image formed by the convex lens is real and can be obtained on the screen.f is used to denote the difference between the principal axis P and the focus F of the concave mirror.How to find the focal length of convex lens?Following are the ways to obtain the focal length of convex lens:The convex lens is thicker in the middle and thinner at the edges and is also known as the converging lens.The refracted rays from the parallel beam of light converge on the other side of the convex lens.If the image is obtained at the focus of the lens, the image would be real, inverted and very small.f is the focal length which is the difference between the optical centre of the lens and the principal focus.The image can be obtained on the screen as the image formed by the lens is real.To determine focal length of a given concave mirrorMaterials RequiredA concave mirrorA measuring scaleA screen holderA mirror holderA mirror standProcedureThe distance between the selected distinct object should be more than 50 ft.The concave mirror placed on the mirror stand and the distant object should be facing each other.The screen should be placed in front of the reflecting surface of the mirror. To obtain a clear, sharp image the screen should be adjusted.Using a metre scale the distance between the concave mirror and screen can be determined. The distance is the same as the focal length of the given concave mirror.Repeat the above procedure thrice to calculate the average focal length.Experimental Setupdetermination of focal length of a thin concave mirrorObservation TableSl.no Position of concave mirror (M) Position of screen (S) Focal length = (M-S)CM1 60 cm 50 cm 10 cm2 60 cm 50 cm 10 cm3 60 cm 50 cm 10 cmSwipe leftCalculationFollowing is the mean value of the focal length of concave mirror:F1+f2+f33cm=10cmResult10 cm is the focal length of the concave mirror.PrecautionsTo get a well illuminated and distinct image of the distinct object, the distant object should be well illuminated.A concave mirror should be always placed near an open window.The polished surface of the concave mirror and the distinct object should be facing each other.There should not be any hurdle between the rays of light from the object and the concave mirror.The screen and the concave mirror stand should be parallel to the measuring scale.The mirror holder along with the mirror should be perpendicular to the measuring scale.To determine focal length of a convex lensMaterials RequiredA wooden benchA convex lensA lens holderA screen fixed to a standA measuring scaleExperimental Setupdetermination of focal length of a convex lensProcedureWithout disturbing the lens and screen, arrange both of them on the wooden bench.Place the lens on the holder facing a distant object.Place the holder with the screen on the bench.The position of the screen should be such that the sharp image of the distant object is obtained on it.The difference between the position of the lens and the screen is equal to the focal length of the given convex lens.Now shift the focus to towards various other distant object and calculate the focal length of the convex lens.Observation TableSl.no Position of convex lens (L) Position of screen (S) Focal length = (L-S) cm1 60 cm 50 cm f1 = 10cm2 60 cm 50 cm f2 = 10cm3 60 cm 50 cm f3 = 10cmSwipe leftCalculationFollowing is the mean value of the focal length of convex lens:f1+f2+f33cm=10cmResult10 cm is the

An elastic modulus is a QUANTITY that MEASURES an object or substance's resistance to being deformed elastically when a STRESS is applied to it. The elastic modulus of an object is defined as the slope of its stress–strain curve in the elastic DEFORMATION region: A STIFFER material will have a higher elastic modulus.

aphy is the art, application, and practice of creating durable images by recording light, either electronically by MEANS of an image sensor, or chemically by means of a light-sensitive material such as photographic film. It is EMPLOYED in many fields of science, manufacturing (e.g., photolithography), and BUSINESS, as well as its more direct uses for art, film and video production, recreational purposes, hobby, and mass communication.Typically, a lens is used to focus the light reflected or emitted from objects into a real image on the light-sensitive surface inside a camera during a TIMED exposure. With an electronic image sensor, this produces an ELECTRICAL charge at each pixel, which is electronically processed and stored in a digital image file for subsequent display or processing.__________________________
