horizontal line

Summary - Like magnetic poles repel and unlike magnetic poles attract. Soft iron gains and loses magnetism faster than steel. A magnetic field is a region in which a magnetic force may be detected. Magnetic field can be plotted with the help of a compass needle. A magnetic field line is a..

Use the leveling screws, attached beneath the base board to make sure that the beam is horizontal. It can be verified with the help of the plumb- line provided shown in the diagram. Use the arrestment knob to raise the beam and the adjusting screw at the two ends of the bea..

As light is transverse in character, all directions of vibrations of electric vector in the unpolarised light are confined to the XY plane. While looking along the X axis, vibrations of electric vector parallel to Y axis are seen and similarly along y axis. Hence light scattered in a direction perp..

Let us suppose that the generator coil ABCD is initially in the horizontal position. As the coil rotates in the anticlockwise direction between the pole N and S of the magnet the side AB of the coil moves down cutting the magnetic lines of force near the N-pole of the magnet and..

. If the intensity becomes too great, the sensation becomes one of pain rather than of hearing. This is indicated by the upper curve which lies close to 10 6 m Wm -2 or 1 Wm -2 , putting 1 = 1 Wm -2 and I 0 = 10 -12 Wm -2 in equation (1-35), we get = 10 log 10 12 = 120 dB A sound of intensity level..

. The slope of a non-vertical line is defined as the tangent of the angle which the line makes with the positive direction of the x-axis. If a non-vertical line passes through two distinct points (x 1 ,y 1 ) and (x 1 , y 1 ), then the slope, m, of the line is..

Altitudinal Biomes - Variations in climatic conditions are observed not only in places on different latitudes but also with altitude. The various types of biomes can also be noted with varying altitudes as seen in the slopes of high Himalayan mountains in Asia, Andes in South America and the Rockie..

Oblique Projectile - The figure above shows a projectile thrown with a velocity v at an angle q with the horizontal. The velocity v is resolved into its two rectangular components, viz., v Cos q along X-axis which is constant, since, the force of gravity in the horizontal direct..

. Each of them is a parabola. The sum of the potential energy and the kinetic energy values remains constant as represented by the horizontal line. At the points where the two curves cross, we can write Equation (2.53) can also be written ..
