n :Since gravitation force provides the necessary centripetal force;∴ The velocity required by an object at distance 2R from centre is found out by putting in 2R in place of R in the above formula.Now the total ENERGY of an object at a height is given by :E= P.E + K.ENow putting in values of v and r as 2R, we get final energy of an orbiting body as :Initial energy of satellite at earth's SURFACE is given by [where v' is the speed provided so as to reach orbit]Now equating due to conservation of energySo the minimum kinetic energy required is : And minimum total energy(with PE component)is: [as obtained for ]Hope this ANSWER helped you :)

0.55 is the ANSWER v=i/r so FORMULA is i=v/r. so i= 220/400= 0.55amp and MAGNITUDE is in OPPOSITE DIRECTION

Resistance DEPENDS on following factors: 1) Length: It is directly PROPORTIONAL to resistance of the conductor. 2) AREA: It is inversely proportional to resistance to the cross SECTIONAL area of the conductor. 3) Temperature: It is directly proportional to resistance.please mark me brainliestitz kavya ❣

tion:the rotation of RIGID BODY is Defined by FILTRATION 0.25 in to 2 second

A pressure gauge MEASURES the pgauge reading as 31 psi. If the atmospheric pressure is 14.2 psi. Compute the absolute pressure that CORRESPONDS to pgauge reading. Answer: GIVEN: patm (Atmospheric pressure) = 14.2 psi pgauge (Gauge pressure) = 31 psi Absolute pressure (pabs) =  patm + pgauge = 14.2 psi + 31 psi pgauge= 45.2 psi HOPE THIS HELPS YOU!!!

From VELOCITY TIME relation conceptv=u+at t= v-u/at= 10-o/30t= 10/ 30t=1/3 seconds HOPE it helpspls THANK me❤❤❤

t=0.5sExplanation:USE KINEMATIC EQUATIONS, v^2-u^2=2as v=ginal velocityu=intial velocitya=accelerations=displacement so, 30×30-10×10=2×a×4 a=100ms^2 now use v=u+at FORMULA 30=10+100t 30-10=100t20=100tt=0.5s

energy is a scalar quantity like other FORMS of energies. CONSIDER a body of mass "m" STARTS moving from rest. After a time interval "t" its VELOCITY BECOMES V. Expression for K.E - KINETIC ENERGY-K.E = m ✔️✔️

Some reasons due to which the shadow cannot be obtained are as follows.1. When the screen is PLACED far AWAY from the ball than he cannot get shadow on the screen.2. The beam of light from the torch is falling parallel to the screen on the ball due to which the ball is not able to obstruct the whole light from the torch and shadow is not obtained.3. The torch is kept away from the ball. This MAKES the source of light far away hence the sufficient light is not reached to the ball.An ACCURATE shadow of the ball will be formed only when the ball, torch, and screen are in the same straight line. The FIGURE below shows the arrangement.

tion:if an object is at rest, then acc. to NEWTONS law resultant force=zeroconsider a column of fluid above that point, pressure=force/area force=mass×accelerationhere acceleration=gmass=DENSITY×height of the fluid column above that point×areasubstitute these values in p=f/a formula. p=density×h×a×g÷a p=density×h×gthis is the formula for pressure at a point in a fluid in any container. here density,h and g will not CHANGE according to container. only area will change but U dont have area in the final formula. so pressure exerted by fluid at rest is INDEPENDENT of the shape of the container.

I THINK it should be 1600N as there are 10 WAGONS

The bending of light as it passes from ONE medium to another is CALLED REFRACTION. The angle and wavelength at which the light enters a substance and the DENSITY of that substance DETERMINE how much the light is refracted.  The bending occurs because light travels more slowly in a denser medium.

There are three different TYPES of pressure:1)ABSOLUTE pressure.2)GAUGE pressure.3)differential pressure.Explanation:A solids exert pressure only on its BASE DOWNWARDS while a fluid exerts pressure at all points in every direction. ... A liquid exerts pressure only on its base downwards while a solid exerts pressure at all points in every direction. C. Both exerts pressure on its base downward.

given that ,the forces of 19N and 28N ACTING in same direction on the body and a force of 75N opposing this MEANS that ,the resultant force=|19+28-75|=|47-75|=|-28|=28Nthis is your ans mate hope it is helpful to you.

Explanation:Approximately half of the flux through a CLOSED surface enclosing the charge. Imagine the closed surface to be a spherical surface just TOUCHING the corners of the GIVEN square. Assume the given square to be in the horizontal plane (as per the question). Consider a vertical section through the centre of the sphere with a diagonal of the square as a chord. If we calculate the radius of the section (and the sphere) we find that it is approximately half the diagonal of the square, which is to be expected since the charge is just 2 mm above the square. The rest follows. Edit: Earlier that was “If we calculate the diameter of the section”. I think that should have been “radius”, now CORRECTED. 541 views · View 2 Upvoters · ANSWER requested by Harsh Singhal (हर्ष सिंघल)

bottle when EMPTY = 25 g.Mass of bottle when completely filled with WATER = 55 g. Therefore mass of water in the bottle = 55 g - 25 g = 30 g. Hence VOLUME of bottle is given by,Since We KNOW that density of water Then,Mass of bottle when completely filled with unknown liquid = 52 g.Therefore mass of the unknown liquid = 52 g - 25 g = 27 g. Hence density of the unknown liquid is given by,Both volumes of liquid and bottle are same.
