Answer:
15.03 m
Explanation:
Given:
mass of the block, m = 7.25 kg
Angle, Θ = 28.5°
Initial speed of the block, v₀ = 15 m/s
let the distance traveled by the block be 's'
Now, applying the work energy theorem,
we have

on substituting the values in the above equation, we get

or

or

s = 15.03 m
Hence, the block will travel 15.03 m up the ramp
Answer:
Hund's rule
Explanation:
Hund's rule is defined as the rule whose first rule in the chemistry says that, for a given electronic configuration, the term which posses lowest energy has maximum multiplicity. The multiplicity is defined as the tem 2S+1, where S is the total spin angular momentum.
Therefore, the term which has lowest energy that term posses maximum number of S.
Hund's rule of maximum multiplicity: Electron present in same energy orbitals firstly they completed half orbit than start pairing.
Therefore, the energy of lowest configuration for an atom is the one having the maximum number of unpaired electron which is allowed by the Pauli principle in a particular set of degenerate orbit is called Hund's rule.
I think that the question is simply asking whether the statement is correct.
The statement is wrong! The scientific endeavor (the work of the scientists, the pursue of knowledge) can be potentially harmful. For example, many tests of human medicine have to be performed on animals, and often the medicine causes great suffering in the animals (and gets rejected for testing on humans).
Answer:
the speed of a jet plane = v = 12 m/s
Explanation:
jet plane that travels 48 meters East in 4 seconds?
<u>use the velocity as distance over time formula = v = d / t</u>
where:
t = 4 sec
d = 48 m
plugin values into the formula
v = <u> 48 m </u>
4 sec
v = 12 m/s
therefore,
the speed of a jet plane = v = 12 m/s
