An atom of an element has 2 electrons in the 1st energy level and 5 on the 2nd energy level what element is it ?

organisms are more likely to be more preserved in mud than sand because mud is moist and wet, while sand is very dry.

b.

the accuracy of the data.

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.
