Explain the difference between general intelligence and specific intelligence.

Answer:

Explanation:

1.The metalloids separate the metals and nonmetals on a periodic table. Also, many periodic tables have a stair-step line on the table identifying the element groups. The line begins at boron (B) and extends down to polonium (Po). Elements to the left of the line are considered metals.

2.left

Metals are located on the left of the periodic table, and nonmetals are located on the upper right. They are separated by a diagonal band of semimetals.

3.Nonmetals are located on the far right side of the periodic table, except hydrogen, which is located in the top left corner. The 17 nonmetal elements are: hydrogen, helium, carbon, nitrogen, oxygen, fluorine, neon, phosphorus, sulfur, chlorine, argon, selenium, bromine, krypton, iodine, xenon, and radon.

4.The metalloids; boron (B), silicon (Si), germanium (Ge), arsenic (As), antimony (Sb), tellurium (Te), polonium (Po) and astatine (At) are the elements found along the step like line between metals and non-metals of the periodic table.

5.Elements are placed in order on the periodic table based on their atomic number, how many protons they have. In a neutral atom, the number of electrons will equal the number of protons, so we can easily determine electron number from atomic number.

6.Each column is called a group. The elements in each group have the same number of electrons in the outer orbital. Those outer electrons are also called valence electrons. ... As you keep counting the columns, you'll know how many electrons are in the outer shell.

7.The periodic table (also known as the periodic table of elements) is organized so scientists can quickly discern the properties of individual elements such as their mass, electron number, electron configuration and their unique chemical properties.

8.two liquid

The two liquid elements at room temperature are mercury (symbol Hg and atomic number 80) and bromine (symbol Br and atomic number 35). Mercury is the only metal that is a liquid at room temperature.

9.  11  gases

There are 118 elements on the periodic table, with 11 of those elements being gases at room temperature. Group 18 (the elements in blue) are noble gases

10.The Group 1 elements in the periodic table are known as the alkali metals. They include lithium, sodium and potassium, which all react vigorously with water to produce an alkaline solution.

11.alkaline earth metals

.

12.transition metals

13.boron group

14.Carbon group element

15.Nitrogen group element

16.chalcogen

17.Halogen

18.Noble Gases

19.element fluorine

20.element fluorine

21.Noble gases are nonreactive

22.The Actinide series contains elements with atomic numbers 89 to 103 and is the sixth group in the periodic table. The series is the row below the Lanthanide series, which is located underneath the main body of the periodic table

23.Group 3

A period 6 element is one of the chemical elements in the sixth row (or period) of the periodic table of the elements, including the lanthanides.

Answer:

m = 62.4 kg

Explanation:

The force applied to the sled, F = 46.8 N

Acceleration of the sled, a = 0.75 m/s²

We need to find the combined mass of the package and the sled. Let it is m. Using definition of force as follows :

F = ma

[tex]m=\dfrac{F}{a}\\\\m=\dfrac{46.8}{0.75}\\\\m=62.4\ kg[/tex]

So, the mass of the package and the sled is 62.4 kg.

Answer:

98 m/s.

Explanation:

In this problem, we need to find the speed of a jumper 10 seconds after jumping. Initially, the bungee jumper was at rest. Let v is the speed after 10 s. Using first equation of motion.

v = u +at

Here, u = 0 and a = g

v = gt

v = (9.8 m/s)(10 s)

v = 98 m/s

So, the speed of a jumper 10 seconds after jumping is 98 m/s.

Answer:

(a). The velocity of star is [tex]8.1\times10^{6}\ m/s[/tex] and the direction of star toward the earth.

(b). The shift is 0.0168 nm.

Explanation:

Given that,

Wavelength of spectral line = 663 nm

Wavelength of spectral line in lab = 645 nm

(a). We need to calculate the velocity

Using doppler's effect

[tex]\Delta \lambda=\dfrac{v}{c}\lambda[/tex]

Where, [tex]\Delta\lambda[/tex]= change in wavelength

v = velocity

c = speed of light

Put the value into the formula

[tex]663-645=\dfrac{v}{3\times10^{8}}\times663[/tex]

[tex]v=\dfrac{3\times10^{8}(663-645)}{663}[/tex]

[tex]v=8144796.38\ m/s[/tex]

[tex]v=8.1\times10^{6}\ m/s[/tex]

The direction of star toward the earth.

(b). Speed = 7800 m/s

We need to calculate the shift

Using formula of shift

[tex]\Delta \lambda=\lambda(\sqrt{\dfrac{1+\dfrac{v}{c}}{1-\dfrac{v}{c}}}-1)[/tex]

Put the value into the formula

[tex]\Delta \lambda=645\times(\sqrt{\dfrac{1+\dfrac{7800}{3\times10^{8}}}{1-\dfrac{7800}{3\times10^{8}}}}-1)[/tex]

[tex]\Delta\lambda=0.0168\ nm[/tex]

This shift is small compare to the the movement of Earth around the sun.

Hence, (a). The velocity of star is [tex]8.1\times10^{6}\ m/s[/tex] and the direction of star toward the earth.

(b). The shift is 0.0168 nm.

Answer:

8.22m

Explanation:

As interpreted from this problem, the angle of launch is 90 degrees as it is thrown straight up. Given an angle launch of 90°, upward initial velocity of 12.7m/s, and initial height of 0m. A much simpler equation can be used to find the maximum height.

[tex]h_{max} = h_ {0} + \frac{{v_0}^{2} }{2g}[/tex]

this means that the max height is equal to the initial height plus the initial velocity squared divided by 2 times the acceleration of earth's gravity(≈9.8m/s^2 or 10m/s^2 depending on how you fix it).

when substituted into the equation, you should get.

(9.8m/s^2)

hmax = 0 + ((12.7)^2)/(2*9.8)

hmax = 161.29/19.6 ≈ 8.22

hmax = 8.22m

Answer:

The answer is 10 m/s north

Answer:

A car travels north at 30.0 m/s for 10.0 min. It then travels south at 40.0 m/s for 20.0 min. What are the total distance the car travels and its displacement?

Let DS & DP denote net distance & net displacement of the car.

Hence from above data we get following relations,

DS = 10*60*30 + 20*60*40

or DS = 18000 + 48000

or DS = 66000 (m) = 66 (km) [Ans]

DP = + 10*60*30 (NORTH) - 20*60*40 (SOUTH) [assuming NORTH as +ve]

or DP = + 18000 (NORTH) - 48000 (SOUTH)

or DP = - 30000 (SOUTH) = - 30 (km) (SOUTH)

At the top of the mountain, when he tightens the cap onto the bottole, there is some water and some air inside the bottle.  Then he brings the bottle down to the base of the mountain.

The pressure on the outside of the bottle is greater  than it was when he put the cap on.  If anything could get out of the bottlde, it would. But it can't . . . the cap is on too tight. So all the water and all the air has to stay inside, and anything that can get squished into a smaller space has to get squished into a smaller space.

The water is pretty much unsquishable.

Biut the air in there can be COMPRESSED.  The air gets squished into a smaller space, and the bottle wrinkles in slightly.

Uranus is a ball of ice and gas, so you can’t really say that it has a surface. If you tried to land a spacecraft on Uranus, it would just sink down through the upper atmosphere of hydrogen and helium, and into the liquid icy center. So it would sink into the planet.                                                                                            

And so would you if your standing on Uranus  ·ω·

Answer:

mutation

Explanation:

Genetic variations in a population are caused by random mutations.

Genetic variations refer to the differences in DNA sequences between individuals in a population. These variations are the result of random mutations that occur in the DNA of organisms over time. Mutations are changes in the genetic code, and they can happen spontaneously during the process of DNA replication or due to external factors such as radiation, chemicals, or environmental influences.

When cells replicate, they sometimes make errors in copying their DNA, leading to new genetic information. These mutations can be neutral, harmful, or occasionally beneficial. Harmful mutations may lead to genetic disorders, whereas beneficial mutations can provide certain individuals with advantages in adapting to their environment.

Over generations, genetic variations accumulate in a population. Natural selection then plays a crucial role in determining which variations are advantageous and which are not. If a particular genetic variation offers a survival or reproductive advantage, it is more likely to be passed on to future generations, leading to evolutionary changes in the population.

Answer:

Option (c).

Explanation:

An object when when projected at an angle, will have some horizontal velocity and vertical velocity such that,

[tex]v_x=v\cos\theta\ \text{and}\ v_y=v\sin\theta[/tex]

[tex]\theta[/tex] is the angle of projection

The horizontal component of the projectile remains the same because there is no horizontal motion. Vertical component changes at every point.

As a projectile falls, vertical velocity increases in magnitude, horizontal velocity stays the same .

As a projectile falls, The vertical velocity increases in magnitude and horizontal velocity stays the same as the components of velocity.

acceleration caused by gravity always affects velocity in the vertical direction, it is a unique sort of velocity. This acceleration, which has a magnitude of around 10 meters/second/second, or 10 meters/second squared, directed downward, toward the center of the earth, affects any object that is hurled up, thrown down, or dropped in a vertical direction.

The thingswhich goess up must come down is a proverb that perfectly captures vertical velocity. Objects will fall back to the earth at a pace of around 10 meters per second every second due to the earth's gravity.

Therefore, As a projectile falls, The vertical velocity increases in magnitude, and horizontal velocity stays the same as the components of velocity.
