The calculation for the horizontal component is performed as follows:
Vhorizontal = V · cos(angle)
For your instance, Vhorizontal = 16 · cos(40) equates to 12.3 m/s
Conclusion: 12.3 m/s
The maximum depth at which he could still breathe, given the pressure of -74 mm Hg, equates to 0.98 m. Pressure of -74 mm Hg translates to 9605 Pa or 9709 N/m². With the density of water set at 1000 kg/m³, we can utilize the pressure equation P = rho g h to determine h, deriving that h = 0.98 m.
Answer: yes.
Explanation: The type of light striking the metal is visible light.
There are three factors involved:
1. The temperature
2. The specific heat of the metal
3. The thermal conductivity of the metal.
The increase in temperature of the metal is influenced by how light energy is absorbed and reflected; it will absorb some of the energy and won't reflect all of it.
When an object absorbs visible light, it transforms the short wavelength light into longer wavelength heat, leading to a temperature rise.
