Explanation:
Basaltic lava
Basaltic lava generally takes two distinct forms known by the Hawaiian terms pahoehoe and aa. Pahoehoe has a smooth wavy surface that resembles twisted rope. It advances by extruding molten toes of lava beneath a thin, flexible crust. As it travels pahoehoe lava often changes to blocky flows called aa.
Answer: C) divide: distance ÷ velocity
Explanation:
The velocity 
equation is distance 
divided by time 
:
If we isolate we will have:
Hence, the correct option is C: distance divided by velocity.
Answer:
C
Explanation:
For a uniformly distributed mass, the center of gravity is also the geometric center. For this shape, the center is at point C.
Answer:
The unit of energy is joule which depends upon the fundamental unit kg, m and sec. So, the unit of energy is a derived unit.
Explanation:
Answer:
Explanation:
Since the cardinal and ball have the same kinetic energy, it is possible to determine the ratio between speeds. (c for cardinal, b for baseball)
The ratio is obtained by multiplying each side by 
:
The value of this ratio is:
