Answer:
aaaaa
Explanation:
M = Mass of the Earth
m = Mass of satellite
r = Radius of satellite
G = Gravitational constant
Solution :
c). 
force applied by Abe
force applied by Barry
force applied by Eric
Resultant force
in the vector form can be written as :
in the vector form can be written as :
The resultant,
= 84.853 N
d). As the three forces are in equilibrium, therefore,
e). The direction of the force exerted by Eric is exactly opposite to the direction of the resultant force.
The direction of the resultant force is :
= 45° north east
The direction of the force E is 45° west or 45° south west.
Answer: C. Some of uranium's mass is converted into energy, so the smaller atoms have less mass.
Explanation:
From Einstein's mass-energy relation:
E = mc²
Mass and energy are equivalent. Mass can be converted into energy and energy into mass.
When Uranium atoms under go nuclear fission, smaller atoms are formed and huge amount of energy is released. This energy comes from the mass difference of the uranium nuclei and new nuclei formed. This mass converted into energy according to Einstein's equation.
Although hand specimen identification is some what of an art; igneous rocks are classified using two critiria:
•Texture
•Chemical and mineral composition
Most of the time the rock name, such as basalt or granite, reflects the chemical composition. The minerals and textures are used as adjectives that modify the rock name. You might see a name like an olivine basalt or a quartz porphyry rhyolite.
