No it does not because this weight is being balanced by a normal source
Acceleration: is the change in velocity divided by the time it takes for the change to occur. . Acceleration is the change in verity divided by the time it takes to make the change, Acceleration has direction.
Answer:
957.4845 m
Explanation:
t = Time taken
u = Initial velocity
v = Final velocity
s = Displacement
a = Acceleration
Time taken by the thunderbird to stop is 6.993 seconds
Time the thunderbird was at the pit is 5 seconds
Time taken to accelerate back to 71.5 m/s is 9.79 seconds
Total time to this point is 6.993+5+9.79 = 21.783 seconds
The Mercedes Benz is moving at a constant velocity hence it has no acceleration and we use the formula
Distance = Speed × Time
⇒Distance = 71.5 × 21.783 = 1557.4845 m
The thunderbird has covered 250+350 = 600 m
So, the distance between them is 1557.4845-600 = 957.4845 m
Answer:
The wavelength of sunlight that can cause this bond breakage is 242 nm
Explanation:
The minimum energy of the sunlight that'll break Oxygen-oxygen bond must match 495 KJ/mol
But 1 mole of any molecule contains 6.02 × 10²³ molecules/mol
Each molecule of Oxygen will require (495 × 10³)/(6.02 × 10²³) = 8.22 × 10⁻¹⁹ J
E = hf
v = fλ
f = v/λ
f = frequency of the sunlight
λ = wavelength of the sunlight
v = speed of light = 3.0 × 10⁸ m/s
E = hv/λ
λ = hv/E
h = Planck's constant = 6.63 × 10⁻³⁴ J.s
λ = (6.63 × 10⁻³⁴)(3 × 10⁸)/(8.22 × 10⁻¹⁹)
λ = 2.42 × 10⁻⁷ m = 242 nm.
