Describe an experiment to show that we can get electrical energy by using amagnet​

Answer»

tion:Experiment to show that we can get electrical energy by using a magnet:The 'magnetic field induction experiment' conducted by Faraday and Henry shows that electrical energy can be produced by using a magnet.To prove this, a paper cylinder was converted to a coil by rolling it with a wire (this setup is called solenoid) and the cylinder was connected to a GALVANOMETER.When a magnet was moved back and FORTH inside the paper cylinder, the galvanometer showed deflections DUE to the induction of CURRENT in the coil.Typically the galvanometer deflected showing the MOVEMENT of current in the coil when the north pole of the magnet was moved near the coil.keep the low voltage bulb it will be good

Velocity(m/s) 15The velocity-time graph of a car is shown in theright sideAnswer the following questions.i) Which part of the graph shows acceleratedmotion? Also calculate the acceleration.ii) Which part of the graph shows retardedmotion? Also calculate the retardation.iii) Calculate the distance travelled by the bodyin first 2 seconds of the journey.D2s6time (5)​

Answer» EXPLANATION:Given graph is a VELOCITY-TIME graph of an OBJECT.In VT graph:1. The SLOPE of the line at a particular time gives the acceleration of the object at that time.2. Area under the graph gives the displacement of the object._______________________________Coming to the questions:1. Part AB is accelerated motion as the slope of the graph(which gives the acceleration) is positive.acceleration = slopeSo acceleration = 1 m/s^22.Part CD is retarded motion as the slope of the graph(which gives the acceleration) is negative.So acceleration = -1 m/s^2Thus retardation is 1 m/s^23.distance of the BODY in first 4 seconds = area under graph from t=0 to t=4sarea under graph from t=0 to t=4s = area of ∆ABE = 1/2 × 4 × 4 = 8mThus distance of the body in first 4 seconds is 8m

. For the series combination of three resistors establish the relation R= R1 +R2 +R3 . Also calculate the equivalent resistance of the combination of three resistors of 6 Ω , 9 Ω, 18 Ω joined in parallel.

Answer»

3 ohmsExplanation:By FORMULA for RESISTORS connected in Parallel, 1/R1 + 1/R2 + 1/R3 =1/RWhere R is EQUIVALENT Resistance.1/6 + 1/9 +1/18 =1/R1/R = 3/18 + 2/18 + 1/181/R = 6/181/R =1/3So, R=3 OHMS

Gravitational force acts on all objects is proportional to their masses. whythem, a heavy object does not fallfaster than aobjectlightso thenfollot​

Answer»

Explanation:GRAVITATIONAL force acts on all objects in proportion to their masses. But a heavy object does not fall faster than a LIGHT object. This is because of the reason that Acceleration= Force/Mass or Force = Acceleration x Mass As force is DIRECTLY PROPORTIONAL to mass, acceleration is constant for a body of any massaccording to the second low of motionF =maie, mass and accelaration are indirectly proportional there for , when mass increases accelaration decreases . So the object is too heavy COMPARED to other ,there is negligible or no accelaration at all so heavy object does not fall faster than a  light object

A beam of light converges at a point P. Now a lens is placed in the path of the convergent beam 12cm from P. At what point does the beam converge if the lens is (a) a convex lens of focal length 20cm, and (b) a concave lens of focal length 16cm? ​

Answer»

Here , the POINT P on the RIGHT of the lens acts as a virtual object u=12 CM , v=? (a) f=20cm As  1/f =1/v -1/u 1/v -1/12= 1/20 1/v =1/20 +1/12= 8/60 v=60/8= 7.5cm IMAGE is at 7.5 cm to the right of the lens where the BEAM converges. (b) f= -16cm , u=12 cm As,  1/f =1/v -1/u 1/v= 1/f +1/u = -1/16 +1/12 = 1/48 v= 48cm Hence image is at 48cm to the right of the lens, where the beam would converge.Hope this helps!

a regular hexagon of side 10cm has a charge 5 MC at each of its verticle. calculate the potential at the center of the hexagon​

Answer» N:A REGULAR hexagon of side 10 cm has a charge 5 micro C at each of its vertices. calculate the potential at the center of the hexagon?Answer:The Potential (V) will be 2.7 × 10⁶ VGiven:Side of Hexagon (a) = 10 cm = 0.1 MEACH vertices has charge (q) = 5 μ CExplanation:We know, that the hexagon is made of 6 equilateral triangles. Therefore, OA = OB = ABHence,⇒ OA = OB = 10 cm = 0.1 mAnd, as we know that potential is a scalar quantity, we will be ADDING all the potential acting on the center by scalar addition.Now,Solving,Here, the Charges are same i.e. 5 μC = 5 × 10⁻⁶ C and distance of separation is same i.e. r = 0.1 m.Substituting the values,∴ The Potential (V) will be 2.7 × 10⁶ V.

Answer»

12thPhysicsRay OPTICS and Optical InstrumentsProblems on Mirror and Magnification FormulaA 4.5 cm NEEDLE is placed 1...PHYSICSA 4.5 cm needle is placed 12 cm away from a convex mirror of focal length 15 cm. Give the location of the image and the magnification. Describe what happens as the needle is moved farther from the mirror.November 22, 2019avatarAsmita SaiShareSaveVIDEO EXPLANATIONANSWERGiven: Height of the needle, H 1 =4.5cm.Object distance, u=−12cm.The focal length of the convex mirror, f=15cm.Image distance, v The value of v can be obtained using the mirror formula.v1 + u1 = f1 v1 + −121 = 151 ∴v=6.7cmHence, the image of the needle is 6.7 cm away from the mirror. Also, it is on the other side of the mirror.The image size is given by the magnification formula.m= hh ′ =− uv h ′ = 126.7×4.5 ⇒h ′ =+2.5cmSo, m= 4.52.5 m=0.56The height of the image is 2.5cm. The positive sign indicates that the image is erect, VIRTUAL, and diminished. If the needle is moved farther from the mirror, the size of the image will reduce gradually.

a ball is realeased from the top of a tower of height h.it takes T s to reach the ground. what is the position of the ball in T/3 s?​

Answer»

ball moves vertically, this is a case of free fall(motion under gravity in 1D). For one dimensional motion we need a REFERENCE frame containing single axis and an origin. Considering vertically downward direction as positive and the point of dropping the ball as the origin of this vertical axis. The acceleration is constant throughout the motion so we can use equation of motion with constant acceleration. Calculations S=ut+1/2at^2 Here u =initial velocity =0 a= acceleration=G t=time of motion S=h = displacement along vertical axis = height of tower. h=1/2gt^2 ………(1) When the particle has moved for a time t/3 s. Let the displacement is x x= 1/2 g (t/3)^=(1/2gt^2)/9 ………(2) From equation (1) putting value in (2) Result x=h/9 Position of the ball at time t/3 is at a DEPTH h/9 from the top of the tower or at a height 8h/9 from the bottom of the tower.

What is realation for heat energy in terms of potential difference and resistance

Answer»

if helps please mark as brainlist answerExplanation:Heat energy is a form of energy. Consider it as potential energy. Potential Difference is a change in relative energy potentials measured between any two points. Energy naturally wants to flow from areas of high potential energy to areas of low potential energy. RESISTANCE is the effect of RETARDING the INSTANTANEOUS flow of energy from an area of high potential energy to an area of low potential energy. Time is relative only to resistance, in that the flow of energy is not instant due to resistance, but OCCURS over time, typically based on the magnitude of the difference. In the CASE of energ...
