Answer:
The first law of thermodynamics defines the internal energy (E) as equal to the difference of the heat transfer (Q) into a system and the work (W) done by the system.
Explanation:
Equation of motion, mathematical formula that describes the position, velocity, or acceleration of a body relative to a given frame of reference.
Only velocity uses direction of travel in its calculations.
Answer:E = hc/? = 4.41 x 10-19 J
Energy absorbed by each atom :
E (atom) = 2.205 x 10-19 J
Now Bond Energy of each molecule (B) = 3.98 x J
So, for each atom 1.99 x 10-19 J
So now
KE of each atom = E(atom) - B (atom)
= 2.15 x 10-19 J
Answer:
Explanation:
v² = u² + 2as
s = (v² - u²) / 2a
s = (29.88² - 6.73²) / (2(5.22))
s = 81.1802203065...
s = 81.18 m
