2 Read the passage and answer the question followed by it. Global warming increases the risk of flooding in certain areas, especially near the equator. Food and medicines packets are dropped by pushing padded boxes from air crafts or with the help of parachutes. 4,500 KG TRI In this case, four boxes were dropped from an aircraft at a place near the equator (as shown in fig). Nearby, at the same time and height an elephant runs off a cliff Which box will hit the ground last? Why? What will the mass of the elephant be if it was running off a cliff near the poles? The red box took 0.6 seconds to reach the ground, What is its speed on striking the ground?(g =10m s?) How high was the red box from the ground? b

i think it because equal matrices have equal dimensions, only square matrices can be symmetric. for all indices and . every square diagonal matrix is symmetric, since all off-diagonal elements are zero. in linear algebra, a real symmetric matrix represents a self-adjoint operator over a real inner product space.

a person with a mass of 106kg has a weight of 1060n

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.
