Answer:

The answer to your question is A = 441.50 km²

Step-by-step explanation:

Data

Big triangle Small triangle

base = 33 km base = 19 km

height = 40 km height = 23 km

Process

1.- Calculate the area of the big triangle

Area = base x height / 2

Substitution

Area = 33 x 40 / 2

= 1320 / 2

= 660 km²

2.- Calculate the area of the small triangle

Area = 19 x 23 / 2

= 437 / 2

= 218.5 km²

3.- Subtract the small area to the big area

Share area = 660 - 218.5

= 441.50 km²

A pot is being used to boil off 1 kg of water. The specific energy required to cause the phase change is 2297 kJ/kg. Assuming th

Answer:

It will take 58 seconds

Step-by-step explanation:

If you have 1 kg of water in the jar, half of it will be 0.5 kg.

To vaporize half of the water (0.500 kg) the energy supply needed is

$2297 kJ/kg*0.5kg=1148.5 kJ$

If the stove is supplying 20 kJ/s, the time its needed is

$\frac{1148.5 kJ}{20\frac{KJ}{s} }=57.425 s$

It will last at least 58 seconds to vaporize half of the water.
