Explanation:
a. The velocity of the wind as a vector in component form will be represented as v vector:
b.The velocity of the jet relative to the air as a vector in component form will be represented as u vector
c. The true velocity of the jet as a vector will be represented as w:
d. The true speed of the jet will be calculated as:
e. The direction of the jet will be:
it cannot be reuse and replaced for long period of time.hope it helps u
You could try the "Spinning Bucket" or the "Center Of Gravity" experiment. There are plenty more that you could research! Hope this helped :)
Answer:
Explanation:
given,
de broglie wavelength of the particle = 2.1 × 10⁻¹⁰m
Kinetic energy increase factor = 3
de broglie wavelength of new particle = ?
we know,
Kinetic energy
...........(1)
Kinetic energy of other particle
............(2)
dividing equation (1)/(2)
Answer:
Explanation:
The mean free path of an atom is given by the following formula:
(1)
Where:
is the Universal gas constant
is the absolute standard temperature
is the diameter of the helium atom
is the Avogadro's number
absolute standard pressure
Knowing this, let's find from (1), in order to find the radius of the helium atom:
(2)
(3)
(4)
If the radius is half the diameter:
(5)
Then:
(6)
(7)
However, we were asked to find this radius in nanometers. Knowing :
(8)
Finally:
This is the radius of the helium atom in nanometers.
