A 0.4 g piece of copper is heated and fashioned into a bracelet. The amount of heat energy transferred by heat to the copper is 6500 units. If the specific heat of copper is 390 units, what Is the change of the copper's temperature?

75 celsisus

Step-by-step explanation:

solution:

→c= a b , that is product of a and b is possible only when when a is m × n matrix and b is n × p matrix.

that is, number of columns of a= number of rows of b.

so, size of matrix , c= a b is , if a = (m × n)matrix

b= (n × p)matrix

then a b = [ (m × n)matrix] ×[   (n × p)matrix ]

→→c= a b= [m × p ] matrix

→→size of product a b will be equal to = number of rows of a × number of columns of b

yes
