you are standing on a ski slope, where the elevation is 5500ft. The lodge at the bottom of slope is at an elevation of 5018ft. The pitch of the ski slope is 20°, how long is the trail?

i believe the answer is c. "baking" is the gerund, while "baking blueberry muffins" would be the gerund phrase. hope this ! : )

distance, luminosity, brightness, radius, chemical composition, and temperature

answer is: nuclear fusion produces elements that are heavier than helium.

nuclei combine to form a heavier nucleus, releasing energy.  

for example, fusion of hydrogen atoms at the sun.  

this fusion nuclear reaction is in the inner core of the sun and hydrogen (atomic number 1) is conveted into helium (atomic number 2).  

the inner core is the central region of the sun and all solar energy is produced in the core by nuclear fusion.
