D. According to the hierarchy of needs the body and mind must be taken care of first and foremost.
The force of impact is same for both bus and the bicycle. The acceleration of bicycle will be greater than the acceleration of bus.
<u>Explanation:</u>
The interaction that occurs between two objects refers to collision. this makes the two objects to come in contact with each other. The third law of Newton states that, when there occurs a collision between two objects, then the force that is applied on each object will be same. But, the direct in which the force is impacted will be in opposite direction.
The magnitude of the forces will be equal but the direction will not be same. The collision results in gaining the momentum by one object and losing momentum by another. The acceleration is mainly associated with the mass of the object. When the object has smaller mass, it will be accelerated more. In the given example, as bus is heavier than bicycle, the bicycle will have greater acceleration than the bus.
Answer:
Explanation:
We have here values from SI and English Units. I will convert the units to English Units.
We hace for the power P,
we have other values such 
and 
(specific weight of the water), and 0.85 for \eta
We need to figure the flow rate of the water (V) out, that is,
Where 
is the turbine efficiency, at which is,
Replacing,
With this value (the target of this question) we can also calculate the mass flow rate of the waters,
through the density and the flow rate,
converting the slugs to lbm, 1slug = 32.174lbm, we have that the mass flow rate of the water is,
Answer:
Mg (atomic number 12)
K (atomic number 19)
Explanation:
The size of an atom is estimated in terms of its atomic radius.
The atomic radius is taken as half of the inter-nuclear distance between two covalently bonded atoms of non-metallic elements or half of the distance (d) between two nuclei in the solid - state of metals.
- Across a period, atomic radii decrease progressively from left to right.
- This is due to the progressive increase in the nuclear charge without increase in the number of electronic shells.
- Down a group, atomic radii increase progressively due to the successive shells of electrons being added which have been compensated for by the increase in nuclear charge.
Cl is further right of Mg in the third period
K is below Na in the first group
