This is Yolanda's desk. What could Yolanda do to increase the amount of force needed to change the motion of the desk? Yolanda could remove objects to decrease the desk's mass, so she would need more force
.
Yolanda could add objects to increase the desk's mass, so she would need more force.

Yolanda could decrease the amount of friction between the desk and floor.

Yolanda could remove objects to decrease the amount of friction between the desk and the floor.

a 20-cm-long, cylindrical graphite (pure carbon) rod is inserted into an oxidizing atmosphere at 1145 k and 1.013 x 105 pa pressure. the oxidizing process is limited by the diffu- sion of oxygen counterflow to the carbon monoxide that is formed on the cylindrical surface.

explanation:

0.07 g/cm³

1.37 g/cm³

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.
