Liz and jacqueline each hit a golf ball off the top of an ocean cliff. lizs ball has a horizontal velocity of 20m/s, while jacqueline's has a horizontal velocity of 30 m/s. both balls are hit at the same time, and neither has any initial vertical velocity. which of the following statements are is true?
a. jacquelines ball will hit the water first, bit liz's will travel further
b. the two balls will hit the water at the same time, but jacquelines will travel further.
c. the two halls will travel the same distance and hit the water at the same time.
d. liz's ball will hit the water first, but jacquelines will travel further.

Write a question about how changing temperature affects the gas inside the sports ball

Under conditions for which the same room temperature is maintained by a heating or cooling system, it is not uncommon for a person to feel chilled in the winter but comfortable in the summer. provide a plausible explanation for this situation (with supporting calculations) by considering a room whose air temperature is maintained at 20â°c throughout the year, while the walls of the room are nominally at 27â°c and 14â°c in the summer and winter, respectively. the exposed surface of a person in the room may be assumed to be at a temperature of 32â°c throughout the year and to have an emissivity of 0.90. the coefficient associated with heat transfer by natural convection between the person and the room air is approximately 2 w/m2 â‹…â‹… k. what is the ratio of the thermal resistance due to convection to the thermal resistance due to radiation in the summer? what is the ratio of thermal resistances in the winter
