Answer:

Your nervous system is your body's command center.

Explanation:

since it is originated from your brain, it controls your movements, thoughts and automatic responses to the world around you.

Answer:

Convergent

Explanation:

I don't know whether this is one of your answers but It is convergent because convergent boundaries are when two plates collide against each other which can create mountains and volcanos.

Answer:

d) 2

Explanation:

We are given;

n = 4, l = 1, m = -1

We can tell that is is an orbital with sub shell as 3P.

Now, from Paul's exclusion principle, each orbital will have maximum of 2 electrons of each π with a spin of +½ and -½.

Since the maximum is seen to be 2, then option D is correct.

Answer:

Light pollution is excessive, misdirected or inappropriate outdoor lighting. Too much light pollution washes out the view of the Universe, increasing energy consumption, interferes with astronomical research, disrupts ecosystems, and affects the health and safety of humans and wildlife.

Explanation:

Light pollution radically alters their nighttime environment by turning night into day. ... “Predators use light to hunt, and prey species use darkness as cover,” Kyba explains “Near cities, cloudy skies are now hundreds, or even thousands of times brighter than they were 200 years ago.

Different visible waves show different colors

In the electromagnetic spectrum, different  visible waves show different colors.

The electromagnetic radiation consists of waves made up of electromagnetic field which are capable of propogating through space and carry the radiant electromagnetic energy.

The radiation are composed of electromagnetic waves which are synchronized oscillations of electric and magnetic fields . They are created due to change which is periodic in electric as well as magnetic fields.

In vacuum ,all the electromagnetic waves travel at the same speed that is with the speed of air.The position of an electromagnetic wave in an electromagnetic spectrum is characterized by it's frequency or wavelength.They are emitted by electrically charged particles which undergo acceleration and subsequently interact with other charged particles.

B. by finding its speed and direction

Kinetic energy is the energy an object has due to its motion. As long as an object is moving at the same velocity, it will maintain the same kinetic energy. The kinetic energy of an object is calculated from the velocity and the mass of the object.

Yes, As the gravity/distance increases between two objects, the gravitational pull between them weakens/strengthens.

There is a gravitational force of attraction between every object in the universe. The size of the gravitational force is proportional to the masses of the objects and weakens as the distance between them increases.

Answer/Explanation:

f is the number of waves produced by a source per second, it is measured in hertz (Hz). T is the time it takes for one complete oscillation, it is measured in seconds. All waves, including sound waves and electromagnetic waves, follow this equation. A radio wave has a time period of 0.0000003333333 seconds.

Explanation:

Answer:

0.01 M

Explanation:

NaOH (sodium hydroxide) is a strong base, so it is completely dissociated into ions in aqueous solution:

NaOH ⇄ Na⁺ + OH⁻

So, we have OH⁻ ions in solution.

From the problem, we have the pH value. The pH is calculated as:

pH = -log [H⁺]

As NaOH is a base, we can also calculate the pOH:

pOH = -log [OH⁻]

Thus. we can use the relation between pH and pOH to calculate the pOH and then use it to calculate [OH⁻]:

pH + pOH = 14 ⇒ pOH = 14 - pH = 14 - 12.05 = 1.95

pOH = -log [OH⁻] ⇒ [OH⁻] = [tex]10^{-pOH}[/tex]= [tex]10^{1.95}[/tex]= 0.0112 M ≅ 0.01 M

Answer:

0.0112

Answer:

Option D. 7.56 g of Hg.

Explanation:

The balanced equation for the reaction is given below:

4HgS + 4CaO —> 4Hg + 3CaS + CaSO₄

Next, we shall determine the mass of CaO that reacted and the mass of Hg produced from the balanced equation. This is can be obtained as follow:

Molar mass of CaO = 40 + 16

= 56 g/mol

Mass of CaO from the balanced equation = 4 × 56 = 224 g

Molar mass of Hg = 200.59 g/mol

Mass of Hg from the balanced equation = 4 × 200.59 = 802.36 g

SUMMARY

From the balanced equation above,

224 g of CaO reacted to produce 802.36 g of Hg.

Finally, we shall determine the mass of Hg produced by the reaction of 2.11 g of CaO. This can be obtained as follow:

From the balanced equation above,

224 g of CaO reacted to produce 802.36 g of Hg.

Therefore, 2.11 g of CaO will react to produce = (2.11 × 802.36)/224 = 7.56 g of Hg.

Thus, 7.56 g of Hg were obtained from the reaction.

Answer:

B)

Explanation:

In beta decay the nucleus loses a neutron and gains a proton. The mass therefore remains constant but the atomic number increases by one.

Explanation:

What would you expect to find?

- The masses of the reactants would be equal to the masses of the product.

Why?

- This is due to the law of conservation of matter which states that matter is neither created nor destroyed in an isolated system but converted from one form to the other.

How is this related to balancing your equations?

- This is why during balancing of equations, we must ensure that the number of atoms in the reactant side must be equal to the number of atoms in the product side.

D. Certain blood vessels are blocked by fatty acids

Explanation:

A heart attack occurs when the flow of blood to the heart is blocked. The blockage is most often a buildup of fat, cholesterol and other substances, which form a plaque in the arteries that feed the heart (coronary arteries). Sometimes, a plaque can rupture and form a clot that blocks blood flow.
