The numbers refer to the mass of each carbon atom.
Since the atoms are all Carbon, the number of protons in each atom is always the same ... if the number of protons changed, then you'd have an atom of something else, not Carbon. The only way the atomic mass can change and still be an atom of the same element is by adding or removing NEUTRONS.
Carbon-14 has two more neutrons in the nucleus of its atoms than Carbon-12 has.
Potential energy = mass x g x height.
height = potential energy/mass x g
acceleration due to gravity on earth is 9.8 m/s
filling in your variables gives us:
490/50 x 9.8 = 1 meter
Refer to the diagram shown below.
Define
= unit vector in the eastern direction
= unit vector n the northern drection.
Then the displacement vectors are
Vector #1:
Vector #2:
Vector #3:
Because the vector sum of all three vector is zero, therefore
1381.1 +0.6561a - 0.891b = 0
703.7 - 0.9873a + 0.454b = 0
That is,
0.6561a - 0.891b = -1381.1 (1)
-0.9873a + 0.454b = -703.7 (2)
From (1), obtain
b = 0.7364a + 1550.1 (3)
Substitute (3) into (2).
-0.9873a + 0.454(0.7364a + 1550.1) = - 703.7
-0.653a = -1407.4
a = 2155.3 mles
From (3), obtain
b = 3137.2 mles
Answer:
The magnitudes of the two displacement vectors are
2155.3 miles and 3137.2 miles.
Answer:
The wire would stick to the magnet????????????????????????
Explanation:
When heat is applied, energy is applied. so since the state is a solid, there is no terms of energy being applied. Energy is basically "frozen" water turns to ice due to the object reaching its freezing point.
