How do human population growth trends differ between developed nations and developing nations?
Answer:
Replacement-Level Fertility
Another important population characteristic that differ btw develop nation and developing nations is relates to births is replacement-level fertility. Replacement-level fertility is the fertility rate that will result in the replacement of the parents in the population. Again, in an ideal world, the human replacement-level fertility rate would be exactly two. This would mean that each couple would produce two offspring that would replace them in the population. If this occurred, then the human population would stay at a stable rate

How do the displacement, velocity, and acceleration of a runner change as he races from the starting
line toward the finish line along a straight path?
Answer:
maybe line toward the finish
Explanation:that question is confusing
Velocity is the pace at which your displacement is shifting; it describes how quickly and in which direction you are travelling. And acceleration, which is measured in meters per second, is the rate at which your velocity is changing (or meters per second squared).
What factor that affect the acceleration and velocity?Net force and mass are the two primary factors that impact how quickly an item accelerates. For instance, mass has an inverse relationship with acceleration while net force has a direct relationship.
The acceleration is also influenced by other elements like friction, air or fluid resistance, and pressure.
According to the second law, the mass of the item and the net force acting on it both impact how quickly an object accelerates.
Therefore, an object's acceleration is directly proportional to the net force applied on it and inversely proportional to its mass.

2. A 0.50 kg football is thrown with a velocity of 15 m/s to the right. A stationary receiver catches the ball and brings it to rest in 0.020s. What is the force exerted on the receiver?
3. A 0.40 kg soccer ball approaches a player horizontally with a velocity of 18 m/s to the north. The player strikes the ball and cases it to move in the opposite direction with a velocity of 22 m/s. What impulse was delivered to the ball by the player?
1. The car should move with velocity of 46.28 m/s
2. The force exerted on the receiver is 375 N
3. The player delivered an impulse of !.6 N s to the ball
What is Impulse?In Physics, Impulse is the product of mass and change in velocity. from Newtons law change in momentum is equal to impulse
m ( v - u ) = f * t = impulse = momentum
m = mass
v = final velocity
u = initial velocity
f = force
t = time
1.
Given:
mass = 1210 kg
momentum = 5.6 x 10^4 kg m/s
change in velocity = v - u = ?
u = 0 so change in velocity = v
momentum = mass * velocity
velocity = momentum / mass
velocity = 5.6 x 10^4 / 1210
velocity = 46.28 m/s
2.
Given:
m = 0.50 kg
u = 15 m/s
v = 0
t = 0.020 s
m ( v - u ) = f * t
f = 0.50 * ( 0 - 15 ) / 0.02
f = -375 N (the negative sign indicates the direction of the stoppage force as against the force that produces the motion )
force = 375 N
3.
Given:
m = 0.40 kg
u = 18 m/s to the North

In question 8 from “Problems 2”, you calculated that an archery arrow shot with an initial velocity of 45 m/s at an angle of 10 degrees would travel 70.67 m (2 d.p.) before hitting a target at the same height from which it was released. If the archery target was moved further away from the archer, discuss some kinematic-based strategies that the archer could adopt to ensure that the arrow reaches the target. Ensure that the variables discussed are relevant to your answer. Assume air resistance is negligible.
The distance traveled by the arrow and horizontal velocity are directly proportional, thus when the distance increases, an increase in initial velocity will allow the arrow to hit the target.
Time of motion of the projectileIf the horizontal distance the projectile would travel before hitting the target is 70.67 m, the time of motion of the projectile is calculated as;
X = Vx(t)
t = X/Vx
t = X/Vcosθ
t = (70.67) / (45 x cos10)
t = 1.6 s
When the archery target is moved further away from the archer, the archer needs increase the initial velocity of the arrow assuming the angle of projection is constant.
Since the distance and horizontal velocity are directly proportional to each other, thus when the distance increases, an increase in initial velocity will allow the arrow to hit the target.

Hold a spoon such that the water will hit the back of the spoon. The handle of the spoon will be horizontal. Turn on the water, but not full strength though.
This is an experiment that explains the Bernoulli principle. According to this principle, at the bottom of the spoon, there will be a reduction in pressure.
Explanation of the Bernoulli principleSo the pressure at the bottom of the spoon reduces because the velocity of the water is larger and the height of the column of water is smaller at this part.
So the spoon is attracted to the water at the point of lowest pressure because objects gravitate to low-pressure points.

In 1923, Sigmund Freud developed the personality theory through which he strongly argued that a person’s personality (human psyche) is structured into three (3) key parts and these include:
The Id (instincts).Ego (reality).Superego (morality).According to Sigmund Freud, wish fulfillment simply means the satisfaction of a human desire through an involuntary thought process such as dreams. Thus, it typically happens to a person when unconscious desires are adequately repressed by both the ego and superego.

In mechanical waves, the energy is transferred through the vibration of the particles.
Mechanical waves are the type of waves that transfers energy through the vibration of particles. Since, mechanical waves require a medium to transfer energy, they carry energy through matter.
Both longitudinal and transverse waves are two types of mechanical waves.
It is known that mechanical waves propagate through medium like matter, water, etc. Therefore, an ocean wave moving through water is an example of a mechanical wave.
