He was the first American to orbit the earth.
I’m assuming it is kinetic energy. When velocity increases there is acceleration therefore it’s moving which then means it has kinetic energy
Answer:
t = 4.0 min
Explanation:
given data:
diameter of rod = 2 cm
T_1 = 100 degree celcius
Air stream temperature = 20 degree celcius
heat transfer coefficient = 200 W/m2. K
WE KNOW THAT
copper thermal conductivity = k = 401 W/m °C
copper specific heat Cp = 385 J/kg.°C
density of copper = 8933 kg/m3
charateristic length is given as Lc
Biot number is given as
Bi = 0.0025
As Bi is greater than 0.1 therefore lumped system analysis is applicable
so we have
............1
where b is given as
b = 0.01163 s^{-1}
putting value in equation 1
solving for t we get
t = 4.0 min
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)
