A transformer is a device that is used to either raise or lower VOLTAGES and currents in an electrical CIRCUIT. In modern electrical distribution SYSTEMS, transformers are used to boost voltage levels so as to decrease line LOSSES during TRANSMISSION.

Light incident from particle P will be reflected at mirroru=−5cm,f=− 2R =−20cmv1 + u1 = f1 v 1 =+ 320 cm This image will ACT as OBJECT for light getting refracted at water surfaceSo, object distance d=5+ 320 = 335 cmbelow water surface,After refraction, final image is ATD ′ =d( μ 1 μ 2 )=( 335 )( 4/31 )= 435 =8.75cm≈8.8cm

For the first half, when ball A GOES upV A =U A −gTV B =−gTV AB =V A −V B V AB =U.......(1)For the second half, when ball A comes downV A =−gTV B =0V AB =V A −V B V AB =−gT........(2)Hence from the equation (1) we observe that relative VELOCITY is independent of T. Which will be valid TILL ball A reaches maximum height point. It is given time taken in reaching h is t.Hence for the time t, V AB will be constant, whereas after time t, relative velocity changes its direction and increases afterwards.

CTExplanation: DISTANCE = SPEED × TIME =C × t = CT

(a) The given STATEMENT is possible.The word acceleration implies a change in the object’s velocity. One EXAMPLE of this is vertical particle projection. When an object is thrown upwards, the MAXIMUM height velocity of the body is zero, but constant acceleration due to gravity is still working.(b)The given statement is possible.The object can move in a certain path with a perpendicular acceleration, in the CASE of circular motion. When an object is moving along a circular motion its path is along the circle tangent but the centripetal acceleration is towards the circle radius. We understand that with the radius, a tangent still makes a right ANGLE. So when the object in the circular motion, the velocity and accelerations are in a mutually perpendicular direction.Explanation: Hope it helps you

(c) 7.5 cmExplanation:F = -10cmm = 4Using the RELATION:m = f/(f-u) 4= -10/(-10-u)-40-4u=-10-4u=-10+40u=30/(-4)u=-7.5 cm

The diagram SHOWS a wire of diameter D and length L that is firmly clamped at one END between two blocks of wood. A load is APPLIED to the wire which extends its length by x. A second wire is made of the same material, but of diameter 2D and length 3L. Both wires obey HOOKE's law.

the pair of plates Ais connected to positive terminal of the battery and the pair of plates BIS connected to negative terminal of the battery, Fig, As is CLEAR from the FIGURE, we have three capacitors 1,2and 3. Positive plates are connected to each othe RAND so are the negative plates. Therefore, these are joined in PARALLEL. Cp=C1+C2+C3= 3C Mark me as the brainlest if the answer helps you..

tion:we say that because burning the fuels release dangerous fumes or gases LIKE carbon DIOXIDE which is harmful.when it is released,it is mixed up or flown ALONG with clouds,when it rains,it is an acid rain.when acid rain or nitrongen dioxide/sulferdiocide falls on Land and trees,the roots absord this acid and die.any person who WOULD be wet by acid rain could have mild allergies or epidermal abrations.uy could cause severe fatigue.as well as harming environment,it can cause some desease when inhaled

Physics is the study of ENERGY and matter in SPACE and time and how they are related to each other. ... For example, velocity and acceleration are used by physics to show how things move. ALSO, physicists study the forces of GRAVITY, electricity, magnetism and the forces that hold things together.

Projectile motion is a form of motion experienced by an object or particle that is projected NEAR the Earth's surface and moves ALONG a curved path under the action of GRAVITY only. This curved path was shown by Galileo to be a parabola, but may ALSO be a line in the special case when it is THROWN directly upwards.

Correct OPTION is (b)Image will be formed 60 CM from the mirror on the same side of the side of object.Explanation:Given,Radius of curvature of Concave mirror, R = -40 cmLocation of object, u = -30 cm To find,Location of Image, v =?So,Using relation → Radius of curvature = 2 × ( focal length )→ R = 2 f → f = R / 2 → f = -40 / 2→ f = -20 cmso, focal length of concave mirror is -20 cm.Now,Using Mirror formula → 1/f = 1/v + 1/u→ 1/(-20) = 1/v + 1/(-30)→ 1/v = 1/(-20) + 1/(30)→ 1/v = (-3 + 2)/60→ 1/v = -1 / 60→ v = -60 cmTherefore,Image will be formed at 60 cm from the mirror on the same side of the side of object.And THUS,OPTION (b) is correct.

Answer: The MAGNITUDE of the test charge MUST be small ENOUGH so that it does not disturb the distribution of the charges whose electric field we wish to measure OTHERWISE the measured field will be different from the ACTUAL field.
