Answer:
Researcher Timothy Salthouse proposes that if the person is mentally active throughout their lives, they will have a cognitive reserve in late adulthood that will help them continue to execute a high mental level.
Explanation:
The psychologist Timothy Salthouse focused his research on cognitive aging, and his study is considered very important in the area since it helped identify the first signs of cognitive impairment.
The psychologist Salthouse considered that if the person had an excellent cognitive reserve would not be strongly affected by the brain deterioration that occurs over the years.
The cognitive reserve is the competition that the brain has to balance the deterioration that occurs over the years in people. This cognitive reserve is related to the actions that the brain performed previously, habits, and knowledge acquired by the person over time.
Therefore, older adults who have taken actions to strengthen their cognitive processing will have better advantages in obtaining the cognitive reserve.

Answer:
approximately 2800
At what composition or over what range of compositions will this maximum temperature be achieved? Answer This problem asks that we specify, for the MgO-Al2O3system, Figure 12.23, the maximum temperature without the formation of a liquid phase; it is approximately 2800C which is possible for pure MgO.
Explanation:
Answer:
pressure = 52804.85 Pa
Explanation:
given data
velocity v1 = 40 m/s
altitude distance d = 5 km
velocity v2 = 70 m/s
solution
we will apply here Bernoullis equation that is
P1 + 0.5 × ρ × v1² = P2 + 0.5 × ρ × v2² ......................1
here P1 and P2 is pressure at point 1 ans 2 and ρ is density of water and V1 and V2 is velocity at point 1 and 2
so at 5 km we get here P1 and ρ from table
P1 = 54019.91 Pa
and ρ is = 0.7364 kg/m³
so from equation 1 we get 54019.91 + 0.5 × 0.7364 × 40² = P2 + 0.5 × 0.7364 × 70²
solve it we get
P2 = 52804.85 Pa
