Answer:
Energy produced by the chip =10,460 Joules.
Explanation:
The specific heat of water is one calorie/gram ° C = 4.186 joules/gram ° C, which is higher than any other common substance. As a result, water plays a very important role in regulating temperature. The specific heat per gram for water is much greater than that of a metal, as described in the water-metal example. Replace the mass (m), the temperature change (ΔT), and the specific heat (c) of the solution in the equation Q = c x m x ΔT, where Q is the heat absorbed by the solution. For specific heat of water we goes as given in the question 4,184 J/kg°C
Q =4184×0.5×(25-20)
=10,460 Joules.
Thus heat gained by water (Q)= Energy produced by the chip =10,460 Joules.
Answer:
No.
Explanation:
No, these metals are not uniformly distributed in the lithosphere, they are present some special regions of earth. Chromium ore is found in many places including South Africa, India, Kazakhstan and Turkey. Cobalt ore deposits are present in the regions of Congo, Canada, Australia, Zambia and Brazil. China, Africa, Australia and Gabon are the regions on the earth where manganese metal is present in large quantity.
Length of wood = 1.2 m
Carlos wants to cut it into 3 equal parts.
So, length of each part = (1.2/3) m = 0.4 m = (0.4×1000) mm = 400 mm
