horizontal line

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 ..

Use the levelling 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 be..

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..

Calcium carbonate and magnesium carbonate obtained from deposits of limestone, chalk, marble, dolomite, oyster shells, stalactites and stalagmites. Vertical or horizontal kilns are used to burn limestone. The kilns have steel shells line with refracting bricks. Calcium oxide or ..

. 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..

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 Rockies in North America. O..

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 direction is zero...

The potential energy decreases linearly with decrease in height. On the other hand, the kinetic energy increases with decrease in height. The horizontal line represents the total mechanical energy. Let us now consider a body sliding down a smooth inclined plane. Consider a smoot..

. 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 ..
