Heat capacity is an intrinsic physical property of a substance that measures the amount of heat required to change that substance's
temperature by a given amount. The specific heat is the amount of heat necessary to change the temperature of 1.00 kg of mass by
1.00°C. Its Sl unit is //(kg-K) or J/(kg C).
Insulation is an important part of the building process; we insulate our homes, schools and businesses to conserve energy. Insulation
helps to help us cool p the summer and warm in the winter. Students were asked to design an insulating box, one that would keep
ice cubes from melting using any of the materials listed above. Which material would you pick? Explain why. Choose ALL the answers
that would apply.
A)
Cork
B)
Copper
It is a solid
D)
It has the lowest specific heat capacity of any solid.

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.)
