Apendulum consists of a 2 kg bob attached to a light string of length 3 m. the bob is struck horizontally so that it has an initial horizontal velocity of 4.1 m/s. for the point at which the string makes an angle of 30° with the vertical, calculate the following: (a) the /s)(b) the gravitational potential energy (relative to its value is at the lowest )(c) the tension in the )(d) what is the angle of the string with the vertical when the bob reaches its greatest )

answer and explanation;

answer: the metamorphic rocks are formed when they are exposed to high pressure and high temperatures. this happens when one of the earth's plates comes in contact with the other plate by traveling in opposite directions, straight into each other or slipping under one another. the friction that is caused by this activity results in   melting of rocks and when it cools they are known as metamorphic rocks. this process needs a controlled amount of pressure and temperature otherwise it may turn into magma.
