What factors affect a pendulum? The only things that affect the period of a simple pendulum are its length and the acceleration due to gravity. The period is completely independent of other factors, such as mass. Does period of pendulum depend on angle? The period of a pendulum does not depend on the mass of […]

What is a focal point of a convex lens? The focal point of a convex lens is the point where light rays parallel to the axis are brought to a point. The distance from the lens to this point is called the focal length of the lens. Which lens has two points of focus? However, […]

Which is the main cause of Tides? Tides are caused by the gravitational pull of the sun and the moon on the earth. Along the Pacific coast, there are usually two high tides of unequal height and two low tides of unequal height approximately every 24 hours. How come we don’t fall off the earth? […]

What color of light is associated with the most energy? The frequency of the radiation is proportional to its energy and the wavelength of the radiation is inversely proportional to the energy. Red is the lowest energy visible light and violet is the highest. Where do we observe colorful light emissions? Colorful light emissions are […]

What causes the orbit? Orbits are the result of a perfect balance between the forward motion of a body in space, such as a planet or moon, and the pull of gravity on it from another body in space, such as a large planet or star. These forces of inertia and gravity have to be […]

Which is better ISRO or suparco? SUPARCO lagged behind on all the technological advances that have made the Indian program a potent force. ISRO has already launched missions to the moon and mars, while SUPARCO has almost become redundant. The starting years of the SUPARCO were full of hope and determination. How many satellites does […]
