Answer:
364 nm
Explanation:
The formula for the energy (E) of a photon in terms of its wavelength λ is
E = hc/λ
We can rearrange this formula to give
λ = hc/E
If E = 5.45 × 10⁻¹⁹ J, then

Answer:
Explanation:
To find the weight (W) of the pond contents first we need to use the following equation:
(1)
Where m the mass and g is the gravity
Also, we have that the mass is:
(2)
Where ρ is the density and V the volume
We cand calculate the volume as follows:
(3)
Where L is the length, w is the wide and d is the depth
By entering equation (2) and (3) into (1) we have:
Therefore, the weight of the pond is 6.65x10⁶ lbf.
