Answer:

A geological engineer

Explanation:

The field of geological engineering is concerned with geology, civil engineering and area of mining , geography and forestry.

Geological engineers apply their knowledge of earth science to solve human problems. Such as creating an equipment using science that can aid in solving the challenge in separating coal from dirt components in an environmental friendly manner.

Geological engineers investigate this that are connected to the earth such as mines, roads, quarries , pipelines, petroleum products, forests and building projects. They also perform surveys on effects of landslides and earthquakes.

A household refrigerator that has a power input of 450 W and a COP of 1.5 is to cool five large watermelons, 10 kg each, to 8°C.

Andreyy89

Answer:

6222.22 sec

Explanation:

Given data the power input to the refrigerator is 450 W

The COP of refrigerator is 1.5

Temperature $T_1=8^{\circ}C$

$T_2=28^{\circ}C$

mass of watermelon =10 kg

specific heat =4.2 KJ/kg°C

The amount of heat removed from 5 watermelon

$Q=mc_pdt=5\times 10\times 4.2\times (28-8)=4200 KJ$

We know that $COP=\frac{Q_1}{W}$

$1.5=\frac{Q_1}{450}$

$Q_1=675$ W=0.675 KW

so time required to cool the watermelon is

$t=\frac{Q_1}{Q_2}=\frac{4200}{0.675}=6222.22 sec$
