Researchers believe that sleep helps strengthen and enhance long-term memory function. Hence, option B is correct.
What is Meditation?Meditation could be thought of as a series of practices that encourage enhanced awareness and focused attention. Meditation is a different way to change awareness that has been shown to have several benefits for psychological well-being.
To feel refreshed and alert when you get up, sleep is a crucial process that allows your body and mind to heal. The body needs adequate sleep to remain healthy and free of disease. Without enough sleep, the brain cannot work efficiently. This may affect your ability to concentrate, think clearly, and process memories.
That's the reason researchers believe that sleep help in enhancing longer memory function.

What is computational models?Using computers to simulate and investigate complicated systems utilizing mathematics, physics, and computer science is known as computational modeling. Numerous variables in a computational model describe the system under study.
In behavioral science, computational modeling aims to employ exact mathematical models to better understand behavioral data. Most frequently, the behavioral data are choices, but they can also be reaction times, eye movements, or other plainly visible behaviors, or even neurological data.

A block m1 rests on a surface. A second block m2 sits on top of the first block. A horizontal force F applied to the bottom block pulls both blocks at constant velocity. Here m1 = m2 = m.
(a)
What is the normal force exerted by the surface on the bottom block? (Use the following as necessary: m and g as necessary.)
Answer:
N = 2mg
Explanation:
Assuming the surface is horizontal
The surface must provide enough normal force to prevent the masses from accelerating in the vertical direction.
(a) The normal force exerted by the surface on the bottom block is N1 = 2mg.
Given that,
A block m1 rests on a surface. A second block m2 sits on top of the first block. A horizontal force F applied to the bottom block pulls both blocks at constant velocity. Here m1 = m2 = m.Based on the above information, we can say that the N1 is 2mg.

Answer:2.02s
Explanation:
At the y component, the tract of the ball is free falling body. The initial velocity at y component is 0 m/s.
Height = 1/2 * g * t^2
20 = 1/2 * 9.8 * t^2
t = (20 * 2 / 9.8)^1/2, t = 2.02s

While you push a box you begin to decrease the force you are exerting on the box. When will the box reach equilibrium?
A. When the force you are exerting on the box is equal to 0.
B. When Fyou on box = -Fbox on you.
C. When the force of the box becomes Fyou on box < Fbox on you
D. The box will never reach equilibrium.
The application of a force on the box overcomes the friction and causes the box to accelerate
While the force is decreasing, the box will stabilize;
B. When [tex]\underline{F_{you \, on \, box} = -F_{box \, on \, you}}[/tex]Reason:
Newton's third Law of Motion states that action and reaction are equal in magnitude and opposite in direction
When the box is pushed with a force, [tex]F_{you \, on \, box}[/tex], the reaction of the box of mass, m, is as follows;
[tex]F_{you \, on \, box}[/tex] = [tex]F_{friction}[/tex] + m × accelerationWhere;
[tex]F_{friction}[/tex] = [tex]-F_{box}[/tex] for example
The negative sign is due to the direction of the friction force, or [tex]F_{box}[/tex] is opposite to the direction of the applied force
When the force is decreased to F₂ = [tex]F_{you \, on \, box}[/tex], such that we have;
[tex]F_{you \, on \, box}[/tex] = [tex]-F_{box \, on \, you}[/tex] , which is the condition for equilibrium, and the net
force is zero and according to Newton's first law of motion, the box moves
at constant speed no acceleration
Therefore the box will reach equilibrium when;

What is the Validity measures of a basketball bouncing
This study was aimed at testing the construct validity of the basketball basic motion skills test instrument (ITK GDBB). The research used descriptive method of 3 basketball experts in the city of Cimahi; 3 experts are the expert in basketball. The instrument used was the ITB GDBB developed by Silvy (2019) consisting of top passing, bottom passing, top service, bottom service, chest passing, bounding passing, overhead passing, and leading ball (dribbling). This instrument consists of 76 items that cover 4 domains in basketball, namely chest pass, overhead pass, bound pass, and dribbling. The validity method used the construct validity of different power types. For the reliability method, it used the Kuder Ricardson (KR) and Objectivity analysis. The results of the construct validity analysis of a total of 76 items show that the score is ranged from 0.67 to 1.00. The construct validity value of 71 items in the basketball game is in the high category (= 1.00), 5 items are in the sufficient category, the relativity score is ranged from 0.75 to 0.98, and the objectivity score is ranged from 0.89 to 0.95. The conclusion is that this test instrument can be used as a standardized basic motion skill test for standardized large ball games for validity in basic motion skills in basketball games for grade VII junior high school students.

How mass and volume of matters are connected to density?
This is a physics question not maths
Answer:
An object's density is the ratio of mass to volume of an object. The mass is how much it resists acceleration when a force is applied to it and generally means how much of an object or substance there is. Volume describes how much space an object takes up.

Which area of astronomy does Kepler's laws address? (1 point)
A. The movement of asteroids in the solar system
B. The movement of the sun in relation to the planets.
C. The movement of planets within the solar system.
D. The movement of stars within galaxies.
Answer:
B
Explanation:
His law describes the orbits of planets around the Sun.
The area of astronomy that Kepler's laws address is the movement of planets within the solar system. The correct option is C.
What is Kepler's law?According to Kepler's first law, "all the planets revolve in elliptical orbits around the sun, with the sun at one of the foci."
Perihelion is the point at which the planet is closest to the sun, and aphelion is the point at which the planet is farthest from the sun.
Kepler's laws of planetary motion, published between 1609 and 1619 by Johannes Kepler, describe the orbits of planets around the Sun.
Kepler's laws of planetary motion represent a watershed moment in the transition from geocentrism to heliocentrism. They establish the first quantitative link between the planets, including Earth.
Thus, the correct option is C.

An engine raises 120kg of water through a height of 40m in 30s.What is the power of the engine take gravity to be = 10m/s.
Answer:
1600 W
Explanation:
Power is the product of force and distance, divided by time.
P = (120 kg)(10 m/s²)(40 m)/(30 s) = 1600 kg·m²/s³ = 1600 W
