Answer:

In the water cycle, evaporation occurs when sunlight warms the surface of the water. The heat from the sun makes the water molecules move faster and faster, until they move so fast they escape as a gas. Once evaporated, a molecule of water vapor spends about ten days in the air.

The human brain has the capacity to generate new neurons throughout the lifespan (option b).

The correct statement regarding the development and growth of new neurons in the human brain is option A. The human brain has the capacity to generate new neurons throughout the lifespan.

1. Neurogenesis, the process of generating new neurons, was once believed to be limited to early brain development and not to occur in adulthood. However, recent research has challenged this notion.

2. Studies conducted on adult brains have provided evidence of neurogenesis occurring in specific regions of the brain, such as the hippocampus, which is involved in learning and memory.

3. Neurogenesis in the adult brain involves the generation of new neurons from neural stem cells. These stem cells have the ability to differentiate into mature neurons and integrate into existing neural circuits.

4. The process of neurogenesis is influenced by various factors, including environmental enrichment, physical exercise, and certain medications.

5. It is important to note that while neurogenesis occurs in the adult human brain, the rate of neurogenesis is relatively low compared to early brain development.

6. In contrast to option B, there is evidence to support the idea that neurogenesis continues to occur in the human brain after birth and throughout life.

7. Option C is incorrect because while glial cells, a type of support cell in the brain, can reproduce and grow in number throughout adulthood, neurons also have the capacity to generate new neurons.

8. Option D is incorrect as several animal species, including primates, birds, and rodents, have been found to experience neurogenesis in various stages of their lives.

In conclusion, option A is the true statement regarding the development and growth of new neurons in the human brain, as neurogenesis can occur throughout the lifespan.

Explanation:

(1) Riley velocity relative to the water after she jumps is 1.7 m/s.

(2) The velocity of the canoe relative to the water is 5.02 m/s.

The given parameters;

(1) Since the lake is still, her velocity relative to the water after she jumps is 1.7 m/s.

(2) Apply the principle of conservation of linear momentum;

m₁v₁  =  m₂v₂

62 x 1.7 = 21v₂

105.4 = 21v₂

[tex]v_2 = \frac{105.4}{21} \\\\v_2 = 5.02 \ m/s[/tex]

Thus, after her leap, the velocity of the canoe relative to the water is 5.02 m/s.

Explanation:

A. is chemically identical to heroin.

Answer:

Explanation:

T = (2π rad / rev) / (25 rad/s) = 0.251327... = 0.25 s

The propeller was turning at 25 rad/s then the period of the propeller will be equal to 0.25 seconds.

In terms of physics, velocity is a vector assessment of the motion's direction and speed. The rate of change in an object's position relative to a reference frame and time is the more precise definition of velocity. Simply put, the concept of velocity informs us of the rate at which an object is travelling in a given direction.

It indicates the rate of motion of objects. Take two moving things like our illustration. If both items are travelling in the same vague direction, it is simple to determine which is moving more quickly.

From the given data in the question,

T = 2π (rad/rev) / 25 (rad/s)

T = 0.25 seconds.

Therefore, the period of this propeller is 0.25 seconds.

The correct answer is C - 7.8 < 7 5/6 < 7.9

Step-by-step explanation:

First, convert 7 5/6 to decimal form --> 7.83.

If you don't know how to convert, think about what 5/6 is equal to and put it in decimal form. Add your decimal to the whole number, and there is your answer.

7.83 is in between 7.8 and 7.9, so it must be the answer.

The best combination of layers that would work best for this purpose is an inner core of steel, no air gap, and an outer layer of glass. Option A is correct.

Thermal mugs have the ability to maintain the internal body temperature and heat of their container. For the heat to be maintained for an extended period of time. The internal core must be lined with steel because it radiates less heat compared to the glass. The steel also has high conductivity and lesser specific heat to keep drinks hot for a long period of time.

Therefore, we can conclude that for thermal mugs to keep drinks hot for as long as possible, the inner core must be lined with steel, no air gap, and contain an outer layer of glass.

Answer:

Explanation:

Answer:

3.7 m

Explanation:

ASSUMING this means extra distance beyond where the cannonball would land WITHOUT the wind assistance but in general ignoring air resistance. Hmmmmmm...tricky

The ball drops from vertical rest to ASSUMED horizontal ground 15 m below in a time of

t = √ (2h/g) = √(2(15)/9.8) = 1.75 s

Without the tail wind, the ball travels horizontally

d = vt = 68(1.75) = 119 m

The tailwind exerts a constant acceleration on the ball of

a = F/m = 12/5.0 = 2.4 m/s²

The average horizontal velocity during the flight is

v(avg) = (68 + (68 + 2.4(1.75)) / 2 = 70.1 m/s

so the distance with tailwind is

d = v(avg)t = 70.1(1.75) = 122.675 m

The extra distance is 122.675 - 119 = 3.675 = 3.7 m
