Answer:
a. 6.41 m/s
b. 120.85 m/s^2
Explanation:
The computation is shown below:
a. Pebble speed is
As we know that according to the tangential speed,
= 6.41 m/s
The 18.84 come from
= 18.84
b. The pebble acceleration is
= 120.85 m/s^2
We simply applied the above formulas so that the pebble speed and the pebble acceleration could come and the same is to be considered
The organism that could be considered as an example of a nekton is: Dolphin
Nekton is aquatic animals that have the capability to move independently within water currents.
Nektons are able to do this because they've developed their own unique mechanism to detect their own way within the currents (such as using biosonar or Antenne)
Answer:
180.04 nm
Explanation:
λ₀ = maximum wavelength for photoelectric emission in tungsten = 230 x 10⁻⁹ m
E₀ = maximum energy of ejected electron = 1.5 eV = 1.5 x 1.6 x 10⁻¹⁹ J
λ = wavelength of light used = ?
Using conservation of energy
Energy of the light used = Maximum energy required for photoelectric emission + Energy of ejected electron
λ = 180.04 x 10⁻⁹ m
λ = 180.04 nm
