By the statement that ohm's law is not a fundamental law of nature? (t or 2 sentences) 4 marks) (c) the circuit shown in figure 1 can be used to measure the resistance of a platinum resistance thermometer (prt). ab is a uniform resistance wire of length 1.0 m and c is a sliding contact on this wire. a standard resistor r is included in the circuit. the position of c is adjusted until the voltmeter v reads zero. figure 1 for use with question (i) by applying kirchhoffs laws to loops adca and bcdb, deduce an expression for the resistance of the prt in terms of1, and the value of the standard resistor. (7 marks) (ii) the prt consists of 9.0 m of wire ofdiameter 8.0 × 10-2 mm. the voltmeter reads 0 v when 0.44 m. if the standard resistor, r, has a resistance of 224 ω, what is the resistivity of platinum? 7 marks)

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.

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.
