Within to the rock cycle, which of the following is NOT correct? Metamorphic rocks may melt to become magma.
Sedimentary rocks may weather to become igneous rocks.
Heat and pressure may change igneous rocks into metamorphic rock
Magma may crystallize to form igneous rocks.

the correct answer would be b. amelia, because the particals of gas move really fast (charged particals) and gas also has a lot of room (particals move independently) so the only answer that has both of those is amelia's.

weight of any object is given by

w = m*g

where m is mass of the object and g is the acceleration due to gravity.

for earth the value of g is 9.8 m/s^2 so

w=117.6 n m=12 g=?

117.6=12g => g=9.8 m/s^2

which is the force of gravity on earth.
