Answer:It’s 5 I believe
Explanation: it says to round to the nearest thousandths, so it’ll be 5.
Answer:
Explanation:
From the question we are told that
Weight of fireman
Pole distance
Final speed is
Generally the equation for velocity is mathematically represented as
Therefore Acceleration a
Generally the equation for Frictional force is mathematically given as
Therefore
Answer:
Explanation:
The energy of a single photon is given by:
where
h is the Planck constant
c is the speed of light
is the wavelength
For the photon in this problem,
So, its energy is
One mole of photons contains a number of photons equal to Avogadro number:
So, the total energy of one mole of photons is
Answer:
The correct option is;
Absolute zero
Explanation:
A Bose-Einstein condensate is known as the fifth state of matter which is made of a collection of ultra cooled atoms (at almost absolute zero degrees -273.15 °C) such that the there is very slight free energy within the atoms which results in almost no relative motion between the atoms. The atoms then combine forming clumps such that phenomena usually observed at the microscopic level such as wavefunction interference become observable at the microscopic level.
