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
The average speed of the car would be 50 mph
Explanation:
Using Newtons second law on each block
F = m*a
Block 1
Block 2
Block 3
Solving Eq1,2,3 simultaneously
Divide 1 and 2
Put Eq 4 into Eq3
Put Eq 5 into Eq2 and solve for a
Substitute back in Eq2 and use Eq4 and solve for T2 & T1
Answer:
Explanation:
Formula and givens
- λ = c / f
- λ is the wavelength
- c = the speed of light
- f = the frequency
- c = 3*10^8
- f = 7.89 * 10^14
λ = ?
Solution
λ = 3*10^8 / 7.89*10^14
λ = 3*10^8/7.89*10^14
λ = 2.36 * 10^7
λ = 236 nanometers. What you use as your solution depends on what what you have been taught.
