Answer: it is located over Ellesmere Island, Canada
Explanation
it is now drifting away from North America and toward Siberia.
Answer:
0.78 m
Explanation:
By the conservation of energy, the energy that they gain from potential energy, must be equal to the kinetic energy. So, for Adolf:
Ep = Ek
ma*g*ha = ma*va²/2
Where ma is the mass of Adolf, g is the gravity acceleration (10 m/s²), ha is the height that he reached, and va is the velocity. So:
100*10*0.51 = 100*va²/2
50va² = 510
va² = 10.2
va = √10.2
va = 3.20 m/s
Before the push, both of them are in rest, so the momentum must be 0. The system is conservative, so the momentum after the push must be equal to the momentum before the push:
ma*va + me*ve = 0, where me and ve are the mass and velocity of Ed. So:
100*3.20 + 81ve = 0
81ve = 320
ve = 3.95 m/s
By the conservation of energy for Ed:
me*g*he = me*ve²/2
81*10*he = 81*(3.95)²/2
810he = 631.90
he = 0.78 m
Answer:
2 
bonds and 2 
bonds
Explanation:
If we consider the the bonding in the 
molecule:
Thus carbon forms double bonds with oxygen:
O = C = O
Now,
We know that double bond comprises of a 
and a 
Since, in the , there are 2 double bonds thus there are 2 bonds and 2 bonds in the molecules.
The positive benefit of the uranium mining will be felt by the people and economy because uranium mining give us enough resource to provide sustainable and low cost method of generating energy.
The environment on the other hand , will only be exposed to the negative impact. If the miners fail to store the waste properly, the uranium could make the environment around it become really toxic and unhabitable.
