2. m kilogram of ice is heated and its temperature increases from -10°C to -5°C. A larger amount of energy is added to the same mass of water and the change in its temperature is from 15°C to 20°C
From these observations, compare the specific heat capacity of ice and water.

Ineed extreme for task 2. my student number is 571721. many to whoever solves this correctly, im in debt to you.

An engineer designs a roller coaster so that a car travels horizontally for 152 ft, then climbs 137 ft at an angle of 34.0° above the horizontal. it then moves 137 ft at an angle of 48.0° below the horizontal. if we take the initial horizontal motion of the car to be along the +x-axis, what is the car's displacement? (give the magnitude of your answer, in ft, to at least four significant figures and give the direction of your answer in degrees counterclockwise from the +x-axis.)
