rgy of the PARTICLE CAN change FORMS. Initially, when the particle is projected from ground ( that is, when you throw a particle STRAIGHT up into AIR) the particle has a lot of kinetic energy because you have given it a pretty large upward VELOCITY. ... When a particle is thrown up into the air, all its initial kinetic energy is converted into gravitational potential energy when it reaches its maximum height.Hope it helps

on CORE is USED in an electromagnet which increases the strength of the magnetic field.electromagnet works on the principle of generating magnetic field by the passage of current in a SOLENOID INSIDE which the soft iron bar is kept.The soft iron core can either be a bar or horseshoe shaped.HOPE IT HELPED !!

re no ways to change the pitch of the notes, outside of varying the string tuning. Perhaps a severe change in TEMPERATURE will have that effect by altering the tension, but its not something musically useful, as each string will react differently.However, some synthesizers have tone bending levers, where you can alter the pitch, up or down by jiggling the LEVER. And many ELECTRIC pianos have controls where you can change the pitch of the whole keyboard up or down.PLEASE MARK AS THE BRAINLIEST

diameter of pipe , d = 200mm radius of pipe , r = 100mm COEFFICIENT of friction, f = 0.04 shear STRESS at a point r = 40mm , = 0.00981 N/cm²we have to find shear stress at the pipe wall.Let shear stress at the pipe wall is first of all, we have to find where is viscous or not . we know, the flow will be viscous if Reynolds's NUMBER less than 2000.use Re = 16/0.04 = 400 < 2000this means flow is viscous. now shear stress in case of viscous flow through a pipe is given by, but is constant across a section as There is no variation of x so, there is no variation of p.so, e.g., so, = 100/40 × 0.00981 =0.0245 N/cm²

c motion, in PHYSICS, motion repeated in equal intervals of time. Periodic motion is performed, for example, by a rocking chair, a bouncing ball, a vibrating tuning FORK, a SWING in motion, the EARTH in its ORBIT around the Sun, and a water wave.Hope it helps

your ANSWER but I am SORRY it is in english✌️✌️

carrying capacity is defined as the AMPERAGE a conductor can carry before melting either the conductor or the insulation. Heat, caused by an electrical current flowing through a conductor, will determine the amount of current a wire will handle. THEORETICALLY, the amount of current that can be passed through a single bare copper conductor wire can be INCREASED until the heat generated reaches the melting temperature of copper. There are many factors which will LIMIT the amount of current that can be passed through a wire.

is your QUESTION???

es that under a constant temperature when the PRESSURE on a gas increases its volume decreases. In other words according to Boyle's law volume is inversely proportional to pressure when the temperature and the number of molecules are constant.The Gas Laws All gases generally show similar behaviour when the conditions are normal. But with a slight change in physical conditions like pressure, temperature or volume these show a deviation. Gas laws are an analysis of this behaviour of gases. The variables of state like the Pressure, Volume and Temperature of a gas depict its true nature. HENCE gas laws are relations between these variables. Let us STUDY more about the important gas laws! Boyle’s Law Boyle’s law states the relation between volume and pressure at constant temperature and mass. Robert Boyle conducted an experiment on gases to study the deviation of its behaviour in changed physical conditions.It states that under a constant temperature when the pressure on a gas increases its volume decreases. In other words according to Boyle’s law volume is inversely proportional to pressure when the temperature and the number of molecules are constant. p  ∝ 1/V p = K1 1/V k1 here is a proportionality constant, V is the Volume and p is the pressure. On rearranging, we get: k1= pV. Now, if a fixed mass of gas undergoes an expansion at constant temperature then the final volume and pressure shall be p2 and V2. The initial volume and initial pressure here is p1 and V1 then according to Boyle’s law: p1×V1 = p2×V2 = constant (k1) p1/p2  =  V2/V1 So according to Boyle’s law, if the pressure is doubled then at constant temperature the volume of that gas is reduced to half. The reason being the intermolecular force between the molecules of the gaseous substance. In a free state, a gaseous substance occupies a larger volume of the container due to the scattered molecules. When a pressure is applied to the gaseous substance, these molecules come closer and occupy a lesser volume. In other words, the pressure applied is directly proportional to the density of the gas. Boyle’s law can be graphically represented  as FOLLOWS:

ond law of thermodynamics states that the TOTAL entropy of an isolated system can never decrease over time. The total entropy of a system and its SURROUNDINGS can REMAIN constant in IDEAL cases where the system is in thermodynamic equilibrium, or is undergoing a reversible process.Please,Mark me as brainliest

e PERIOD is directly PROPORTIONAL to the AMPLITUDE a.Explanation :LET the eqn of the SHM , X = asinωt Given,U = k[x]=> Force F = -dU/dx = -k..................eqn1also for SHMd²x/dt² + ω²x = 0=> d²x/dt² = -ω²x=> force F = ma = m*d²x/dt² = -mω²x............eqn2from eqn1 and eqn2 we get,k = mω²x=> ω = √(k/mx) = √(k/m*asinωt)Time period of oscillation,T = 2π/ω=> T = 2π/√(k/m*asinωt) = 2π x √m*asinωt/k=> T ∝aHence the time period is directly proportional to the amplitude a.

Concave MirrorConvex MirrorStructureA concave MIRROR is a spherical mirror in which the reflecting surface and the CENTER of curvature fall on the same side of the mirror. In other words, if the mirror coating lies outside of the spherical surface, then it is known as a concave mirror.A convex mirror is a spherical mirror in which the reflecting surface and the center of curvature lie on the opposite sides of the mirror. In other words, if the mirror coating lies in the inside of the spherical surface, then it is known as a convex mirror.Other nameConverging MirrorDiverging Mirror, Fish eye mirrorImage projectionCan be projected on a screenCannot be projected on a screen.MeaningConcave means “hollowed or rounded”.Convex means “curved or rounded like the outside of a sphere or circle”.Image(C stands for center of curvature, F for focal point and V for vertex)POSITION of object (infinity) Position of Image (At F) Character of Image (Real, zero size)Position of object (between infinity and C) Position of Image (Between F and C) Character of Image (real, inverted, diminished) Position of object (AT C) Character of Image (Real, inverted, same size)Position of object (Between C and F)  Position of Image (Between C and infinity).

The curvature of the object ascertains the extent to which light is bent and in which direction. They are used in spectacles, microscope and telescopes. BASED on the shape, the lens can be grouped as a convex lens or concave lens. The former brings together the parallel beam of light, while the latter disperses it.hope it helps u plz mark me brainlist #varun

ion index: It is the ratio of peak value of modulating signal to the peak value of carrier wave.*Physical significance of MODULATION index It is used to DETERMINE the STRENGTH and quality of transmitted signal. If the modulation index is small, then the amount of variation in the carrier amplitude is small.Thus, the audio signal transmitted willnot be strong. The greater the degree of modulation, die stronger and CLEARER will be the audio signal during reception.Hope this was HELPFUL to u

the ABSENCE of any atmosphere, there will be no SCATTERING of sunlight and the sky will appear dark. (b) In the visible spectrum, the red colour has the largest wavelength. The red colouris LEAST scattered by fog or dust particles. Therefore, we can observe red colour easily even in foggy and dusty CONDITIONS.

ed of car is equal to 25 km an hour,so, 25KM = 1hr 500km = 20because, 25 = 1, 250 = 10 so obviously 250×2 =10×2 500km =20hrsif the bus takes 10 HOURS more than the car, than the speed of the bus and the car are :-in a car = 500km = 20+10 hrs. = 500km = 30 hrs. = 50km = 3 hrs. = 16.67km = 1 hr. = the speed of bus = 17 km. an hour (approx.)ANS.= the speed of bus = 17 km. an hr.
