motion lights problems

Consider a simple system in which two blocks are connected by a string which passes over a light, frictionless pulley as shown below. M 1 a = T-m 1 g M 2 a = m 2 g-T a (m 1 + m 2 ) = (m 2 - m 1 )..

Light is a form of energy. Energy can be transferred from one point to another point either by particle motion or by wave motion. Accordingly, different theories on the nature of light have been proposed. The important theories are as follo..

Whenever there is a relative motion between a source of light and the observer, the apparent frequency of light received by the observer is different from the true frequency of light emitted actually from the source of light..

Light has varied effects on germinating seeds of different plants. Some seeds need light for germination, while in some seeds germination is hindered by light..

Both quality and intensity of light influence the rate of photosynthesis. As the intensity of light increases, the rate of photosynthesis also increases. At a very high light intensity the rate of photosynthesis decreases as chlorophyll itself is destroyed due to high..

Kinematics deals with the study of motion without taking into account the cause of motion.Dynamics is concerned with the cause of motion, namely forc..

Introduction - In the physical world, one of the most common phenomena is motion. The branch of Physics, which deals with the behaviour of moving objects, is known as mechanics. Mechanics is further divided into two sections namely Kinematics and Dynamics. Kinematics deals with the study ..
