Answer:
Physical sciences are those academic disciplines that aim to uncover the underlying laws of nature - often written in the language of mathematics. It is a collective term for areas of study including astronomy, chemistry, materials science and physics.
Explanation:
If that statement were true, then you would never have any reason to eat.
It might taste good for a while, but it would never help you stand up and
move around.
Where WOULD you get the energy to stand up and walk, if it didn't
come from food ? ?
The whole idea is pretty absurd. I guess the statement is not true.
Answer:
b. 5 N
Explanation:
Each book weighs 5 N. Therefore, five books weigh 25 N. The friction force is:
Ff = Fn μ
Ff = (25 N) (0.2)
Ff = 5 N
When the earth in its translation movement has the earth's axis is further from the sun and the energy per unit area is minimal, we have the winter season
The translation is the movement of the earth around the Sun, this movement establishes the duration of the year, also the earth's axis is inclined about 23.5º in relation to the orbit.
A consequence of this inclination of the Earth's axis is that the solar rays reach the surface of the planet with different inclinations, when they arrive more perpendicularly the energy deposited by the surface unit is greater and therefore the temperature increases, this period is called Summer.
When the rays arrive with the greater inclination, the energy deposited per unit area is minimal, which is why the temperature decreases, this period is called Winter.
In the periods when the axis is almost vertical we have an average absorption of energy, these two periods are called Spring and Autumn.
In conclusion, the winter season occurs when the terrestrial axis is furthest from the sun and the energy per unit of area is minimal.

Answer:
d = .076 m
Explanation:
The time for frog A can be calculated from equation of motion
where v_f is final velocity, a is acceleration due to gravity
so from given data we have
t = 0.112 sec
Now we will use that time for frog B
(Note its positive)
For the displacement
d = .076 m
