8. A tidal hydropower plant located close to a small city has a power of 150 [MW] and can potentially deliver 60 [GWh] electricity annually to the city. The city consists of 10.000 houses with each an annual electricity demand of 3000 [kWh] and a heating demand of 10000 [kWh]. All houses are equipped with a gas combustion boiler with an efficiency of 0.9 on HHV. The CO2-eq emissions of the boiler are 0.2 [kg] CO2-eq/kWh HHV. How much CO2 will be saved if the household switches to heat pumps with SCOP 4 and the electricity is delivered by the hydropower plant (chose the closest value to your result)? (multiple choice, one answer) 0 ton CO2-eq 15400 ton CO2 eq 22200 ton CO2 eq

Pierrot the trekker was travelling 12.0 [km], 30.0° S of E, then 15.0 [km], 45.0° N of E, and then 9.00 [km], 30.0° E of N. At the end of this trek, he realized that in the last leg he should have travelled 16.0 [km], 60.0° N of Winstead of the third path he originally took. Having found treasure, Pierrot called for an airlift. The airlift is located 80.0 [km], S, from his initial position. In magnitude-bearing form, determine the path the airlift must take to reach Pierrot.Magnitude:Angle in degrees:Direction: The aircraft took a detour by travelling 50.0 [km], 30.0° S of W from its original location, to a gas station.
