Answer:
A) 1384.6 J/g
b)110.768 MJ
Explanation:
Given data:

density of titanium = 4.5 g/cm^3
specific heat = 0.544 J/g degree C
heat of fusion = 419 J/g
Pouring temperature for titanium = 1800 degree C
Initial temperature = 25 degree C
a) eneegy for heating unit mass is given as


= 1384.6 J/g
b) Total energy to heat 80 kg metal
we know for one unit 1384.6 J/g energy is required
therefore for 80 kg , energy required is

= 110768000 J

Answer:
B

What is topographical survey?
A topographical survey, often known as a land survey or topographical land survey, is a type of survey that includes contours. Topographical land surveying determines the exact location and specifications of natural and man-made features on a piece of land. The survey is then turned into a suitable and thorough plan, which incorporates man-made characteristics such as boundaries, neighbouring buildings, sidewalks, and so on. Natural elements such as trees, ponds, and ground contours are also detected by the topographical survey. Having a clear and accurate map of your property might help you avoid costly downstream mistakes caused by unforeseen challenges. It can supply you with the information you need about the land before making any alterations to it.
