A tool or machine's work efficiency is represented by the ratio of the amount of energy exerted and the amount of work done by the object. Thus, if you exert 1500 J work and the hammer does 825 J, the work efficiency is
Thus, the efficiency of the hammer is 55%.
Answer: 55%
Answer:
C. ns² np^5
Explanation:
An electron gets more electro-negative as it increases in number of electrons until it shell gets filled up. At the point when its shell is filled up, the electron becomes neutral; i.e. not positive and not negative.
Only ns² np^5 satisfies this condition; reason being that it has higher electrons
Be(g) + e + 241 kJ ==> Be^-(g) EA = +231 kJ/mol. (endothermic)
Considering the example above
Also, electron affinity is referred to as the amount of energy absorbed when there's an additional electron to an isolated gaseous atom which forms an ion with a 1- charge by assigning a positive value when energy is absorbed and a negative value when energy is released

Explanation:
<u>Displacement
</u>
It's a vector magnitude that measures the space traveled by a particle between an initial and a final position. The total displacement can be obtained by adding the vectors of each individual displacement. In the case of two displacements:
Given a vector as its polar coordinates (r,\theta), the corresponding rectangular coordinates are computed with
And the vector is expressed as
The monkey first makes a displacement given by (0.198 km,0°). The angle is 0 because it goes to the East, the zero-reference for angles. Thus the first displacement is
The second move is (145 m , -15.8°). The angle is negative because it points South of East. The second displacement is
The total displacement is
In (magnitude,angle) form:

LOL
I think there would be 2 oxygen atoms,
If h2o is two hydrogen atoms and 1 oxygen atom then h2o has 2 potassium atoms and 1 oxygen atom, if you were to add them then together it would have 2 oxygen atoms, plz if I'm wrong correct me
