Regular exercise has a positive impact on the brain, and the best explanation for this is that exercise helps maintain and create pathways in the brain (Option C).

1. The brain is a complex organ composed of billions of nerve cells called neurons. These neurons communicate with each other through pathways, forming a vast network.

2. When we engage in physical exercise, it increases blood flow to the brain. This enhanced blood flow delivers more oxygen and nutrients to the brain cells, promoting their overall health and functioning.

3. Exercise also stimulates the release of various chemicals in the brain, such as neurotransmitters and growth factors. These substances play a crucial role in the growth, development, and maintenance of brain cells.

4. Additionally, regular exercise has been found to promote the formation of new connections between neurons, a process known as neuroplasticity. These connections, also called synapses, are essential for learning, memory, and overall cognitive function.

5. By engaging in consistent exercise, individuals can enhance neuroplasticity, allowing their brains to adapt and reorganize in response to new experiences and challenges.

6. Moreover, exercise has been shown to reduce the risk of age-related cognitive decline and neurodegenerative diseases, such as Alzheimer's disease. It may also help improve mood, reduce stress, and enhance mental well-being.

7. In summary, while the brain is not a muscle that can be directly exercised, regular physical exercise positively impacts the brain by promoting neuroplasticity, improving blood flow, releasing beneficial chemicals, and reducing the risk of cognitive decline.

Therefore, the best explanation for why a consistent exercise regime has a positive impact on the brain is that exercise helps maintain and create pathways in the brain (Option C).

This question involves the concept of the resolution of a vector into its rectangular components.

The horizontal component of velocity is "1.4 m/s", and the vertical component of the velocity is "7.9 m/s".

In order to find the horizontal and vertical components of the velocity of Esther, we must resolve the velocity vector into its rectangular components. Hence, the following formulae will be used:

[tex]Horizontal\ Component = v_x = v\ Cos\theta\\v_x = (8\ m/s)(Cos\ 80^o)\\v_x = 1.4\ m/s[/tex]

[tex]Vertical\ Component = v_y = v\ Sin\theta\\v_y = (8\ m/s)(Sin\ 80^o)\\v_y = 7.9\ m/s[/tex]

Answer:

A 925 kg car accelerates uniformly from rest to a velocity of 25.0 mls south in 10.0 s. What is the net force acting on the car during this time?

F=(925*25)/10

F=2312.5 N to south

Hi there!

We can begin by calculating the acceleration experienced by the car.

vf = vi + at

The initial velocity is 0 (at rest), so:

25 = at

25/10 = a = 2.5 m/s²

Using Newton's Second Law:

∑F = ma, where:

∑F = net force (N)

m = mass (kg)

a = acceleration (m/s²)

Plug in the values:

∑F = 925 · 2.5 = 2312.5 N

Explanation:

For telescopes in general, ever since they were invented, it's the size of the objective lens (in the front) or mirror (in the back).

For the most hugest humongous telescopes, built in the past few decades, it's limited by the turbulence of the atmosphere.  That's the main reason we started building the big ones on mountain tops and in deserts, and lately we've started putting them in Earth orbit, where they don't have to look through any air at all.

Explanation:

This is a Newtons to weight conversion.

Fg = weight

Fg = N/9.8

Answer:

F1 = K Q Q / R^2

F2 = K 2Q * 2Q / (2 R)^2 = K 4 Q^2 / (4 R^2) =  K Q^2 / R^2

F1 = F2 and (e) is  the correct answer

The force between the two charges will be the same, so the new force is the same. Hence, option (e) is correct.

When put in an electromagnetic field, charged matter experiences a force due to the fundamental property of electric charge. Positive or negative electrical ions are possible. When two charges are in opposition to one another, they repel one another.

The term "neutral" refers to an object that has no net charge. The early understanding of the way charged particles interact is now referred to as classical electrodynamics, and it is still true for issues that do not demand taking into account quant phenomena.

As per the given data provided in the question,

F(1) = K (Q)(Q) / R²

After applying the given condition in the question,

F(2) = K (2Q) × (2Q) / (2 R)²

= K 4 Q² / (4 R²)

F(2) =  K Q²/ R²

Which means that F1 = F2.

Therefore, it concludes that option (e) is correct.

Less friction

Explanation:

Paolo's bike is too difficult to pedal because there is too much friction in the mechanisms of the bike. To reduce friction, Paolo must oil the chain. This will make the bike run much more smoothly and allow for easier pedalling.

North: it increases.

South: it decreases.

At the North pole: it's straight up over your head.

At the equator: it's on the horizon, north of you.

m is mass

And c is a constant for speed of light

Answer:

One of the most famous and well-known equations in all of human history, E = mc^2, translates to "energy is equal to mass times the speed of light squared." In other words, wrote PBS Nova, energy (E) and mass (m) are interchangeable. They are, in fact, just different forms of the same thing.

Answer:

Below

Explanation:

We can use this formula to find the acceleration of the crate :

     acceleration = net force / mass of object

Plug in our values :

     acceleration = 50 N / 50 kg

                           = 1 m/s^2

     acceleration = 100 N / 50 kg

                           = 2 m/s^2

     acceleration = 150 N / 50 kg

                           = 3 m/s^2

     acceleration = 200 N / 50 kg

                           = 4 m/s^2

Density is their RATIO, but you can't tell if the sample is the size of an ant or a school-bus.

Answer:

Explanation:

Basically because they are big and relatively near.

The light coming from a star travels a huge distance and is acted upon by the earth's atmosphere with causes all sorts of shifts. What we are seeing twinkle is caused by these shifts, for the most part caused by atmospheric density and heat.

The beam from a planet is not narrow enough to be affected the way the stars are.. If you were out in space looking at all this, the stars would not appear to twinkle either.
