For a mass of 2 kg, the velocity-time graph is given here. Find the force experiencedby the mass in regions OA, AB and BC. |
|
Answer» Force for OA = 4 N.Force for AB = 0 N.Force for BC = -4 N...Explanation:...For OA acceleration = 2 m/s² {change in VELOCITY / time}...so force = maF = 2×2= 4 N.F = 4 N...For AB there is no change in velocity so the work done = zero.For BC acceleration 0-20/10 { (velocity final- velocity initial)/time}acceleration = -20/10acceleration = -2 m/s²Force = ma = 2×-2= -4NForce = -4N... |

explain with help of a diagram the distribution of magnetic due to current carrying coil that has n turns. such that the field produced at any point is n times as large as that produced by a single turn. |
|
Answer» AnswerElectric current in a circular loop creates a magnetic field which is more concentrated in the center of the loop than outside the loop. Concentric circles are formed, which are centered at the point on both sides of the loop as shown in figure A. The lines near the center of the loop are almost STRAIGHT. The magnetic field at the center of the loop is perpendicular to the plane of the loop. The concentric circles BECOME larger as we move away from the wire because as the distance increases from the current carrying conductor the strength of the magnetic field fades away. In same way, when we consider an electric current passing through a circular coil with N number of turns, say a solenoid, the strength of the magnetic field is directly proportional to the number of turns of the solenoid. That is, as the number of turns increases in the coil, the strength of the solenoid also increases. The diagrammatic REPRESENTATION is GIVEN above in figure B. |

Explain forward biased in p-n juction diode and draw characterstic curve |
|
Answer» tion:Forward bias CHARACTERISTICS. When the p -section of the diode is connected to positive terminal of a battery and n-section is connected to negative terminal of the battery then JUNCTION is said to be forward BIASED. With increase in bias voltage, the forward current increases slowly in the beginning and then rapidly. At about 0.7 V for SI diode (0.2 V for Ge), the current increases suddenly. The VALUE of forward bias voltage, at which the forward current increases rapidly, is called cut in voltage or threshold voltage. |

In diffraction from straight edge, source of a light with wavelength 5000 Angstrom is at 2m away from straight edge and the screen is placed 4 m away from straight edge.The position of the first bright band from P is |
|
Answer» As the wavelength increases, the spacing between the nodal LINES and the anti-nodal lines increases. That is, the nodal and antinodal lines spread FARTHER apart as the wavelength GETS larger. In 1801, Thomas Young used a two-point source interference pattern to MEASURE the wavelength of light.www.physicsclassroom.com › iplThe Physics |

Find the distance between two stones each of mass 2 kg so that the gravitational force berween them is IN |
|
Answer» Newton's Law of Gravitation states that the gravitational force between any two objects is the product of their masses divided by the distance between their centres of mass squared all MULTIPLIED by the gravitational constant. there fore F = (GM1M2)Gravitational constant = 6.67x10^-11 , F = 1 and m1 and m2 = 2 APPLY in above formula we GET 1 = (6.67x10^-11 x 2 x 2)/r^2 rearranging, we get r^2 = 6.67x10^-11 x 2 x 2 THEREFORE r^2 = 2.6692x10^-10 therefore r = 1.634x10^-5 m |

Answer» 1 Answer. The magnetic poles always exist in pairs. It is not possible to separate the two poles of a magnet. If a bar magnet is broken at the middle in two parts each part is found to be a magnet.2) answer .The north-seeking pole of such a magnet, or any similar pole, is called a north magnetic pole. The south-seeking pole, or any pole similar to it, is called a south magnetic pole. Unlike poles of different magnets attract each other; like poles repel each other.3) answer. GravityGravity is an attractive force that ACTS between any objects at any distance regardless of their composition. In CONTRAST, the other FORCES in nature can be bothattractive and repulsive. The electricforce is attractive between unlike charges and equally repulsive between like charges.4) answer.

Answer» There are only two POSSIBILITIES of the position of the object in the case of a concave LENS: Object is at infinity - A highly diminished point-sized, VIRTUAL and erect image is formed when the object is at infinity by a concave lens at principal focus F1. Object is between optical centre, O and infinity - A diminished, virtual and erect image is formed between principal focus F1 and optical centre, O; when the object is placed between optical centre and infinity of a concave lens. |
