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.

Using Newton's second law;
F = ma, where m = mass, a = acceleration or deceleration
a = Δv/t = (v-u)/t, but v= 0, u = 10 m/s, t = 1.
Then,
a = (0-10)1 = -10 m/s^2
Substituting;
F = ma = 10*-10 = -100 N
The mattress exerts 100 N to stop the ball.
Answer:
82.7 m
Explanation:
u= 22m/s
a= 2.4 m/s^2.
t= 3.2 secs
Therefore the distance travelled can be calculated as follows
S= ut + 1/2at^2
= 22 × 3.2 + 1/2 × 2.4 × 3.2^2
= 70.4 + 1/2×24.58
= 70.4 + 12.29
= 82.7 m
Hence the distance travelled by the truck is 82.7 m
The term phenotype in a more specific context to describe the collective expression of the genotype in conjunction with the environment on a plant's observable characteristics.
<u>Explanation</u>:
- Phenotype, any of the measurable features of an organism arising from its genotype association (total genetic inheritance) with the environment. Behaviour, biochemical properties, colour, form, and scale are examples of measurable characteristics.
- An allele is another type of one gene. A phenotype triggered by the expression of a gene or group of genes is the external manifestation of a human trait.
- A trait is an attribute unique to an organism. The genotype's external expression is called the phénotype.
Answer:
D
Explanation:
The wrecking ball transfers kinetic energy to the wall.
