In terms of morphology, Homo rudolfensis and <u>Homo habilis </u>can be considered to be one species.

An extinct species of early Pleistocene humans known as Homo habilis, or "handy man," lived in East and South Africa between 2.31 million and 1.65 million years ago. When H. habilis was first described as a species in 1964, there was a lot of debate about it.

Many scientists suggested that it be grouped with Australopithecus africanus, the only other early hominin that was known at the time, but as time went on and more pertinent discoveries were made, Homo habilis gained more recognition. By the 1980s, it was believed that Homo habilis was a direct progenitor of modern humans, developing into Homo erectus along the way.

Mga oras na iniluwal ng panahon kahulugan<br>

Mila [183]

Answer:

Ang panahon o kalagayan ng panahon ay ang paglalarawan sa kalagayan at katangiang pangkalikasan sa labas ng tahanan, gusali o anumang tirahan ng tao, hayop, halaman at iba pang mga nilalang, na ayon sa singaw ng kalawakan o ng atmospera ng daigdig. Tumutukoy ito sa kainitan, katuyuan, kalamigan, kabasaan, katahimikan, pagka-maaraw, pagkamahangin, o pagiging maulan sa isang pook, sa isang takdang oras, na maaaring magbago. Nararamdaman, naririnig, nakikita ng tao ang epekto ng panahon at maging ang pagbabago sa kalagayan nito. Nasusukat din ang panahon sa pamamagitan ng mga termometro, barometro, barograpo, sikrometro o higrometro, panukat ng hangin, anemometro, at mga panukat ng ulan. Depende rin ang taya ng panahon sa pagdating ng kapanahunan ng tag-init, taglamig, taglagas, tagsibol at tag-ulan.[1]

An ice skater has a moment of inertia of 5. 0 kg∙m2 when her arms are outstretched. At this time she is spinning at 3. 0 revolut

Sindrei [870]

Answer:

2440.24 J

Explanation:

Moment of inertia, I1 = 5 kg m^2

frequency, f1 = 3 rps

ω1 = 2 x π x f1 = 2 x π x 3 = 6 π rad/s

Moment of inertia, I2 = 2 kg m^2

Let the new frequency is f2.

ω2 = 2 x π x f2

here no external torque is applied, so the angular momentum remains constant.

I1 x ω1 = I2 x ω2

5 x 6 π = 2 x 2 x π x f2

f2 = 7.5 rps

ω2 = 2 x π x 7.5 = 15 π

Initial kinetic energy, K1 = 1/2 x I1 x ω1^2 = 0.5 x 5 x (6 π)² = 887.36 J

Final kinetic energy, K2 = 1/2 x I2 x ω2^2 = 0.5 x 3 x (15 π)² = 3327.6 J

Work done, W = Change in kinetic energy = 3327.6 - 887.36 = 2440.24 J

The maximum number of electrons that may occupy the third electron energy level is

stira [4]

Considering the electronic configuration, the maximum number of electrons in the third electron is 18 electrons.

<h3>Electronic Configuration</h3>

The Electronic Configuration of the elements is the arrangement of all electrons of an element in energy levels and sub-levels (orbitals).

There are 7 energy levels, numbered from 1 to 7, and in which electrons are distributed, logically in order according to their energy level. Electrons with less energy will be spinning at level 1.

Each level is divided into sub-levels. These sub-levels into which each level is divided can be up to 4. These 4 sub-levels are called: s, p, d, f. In the sub-level s there can only be a maximum of 2 electrons, in p there can be a maximum of 6 electrons, in the sub-level d 10 electrons and finally in the sub-level f there can be a maximum of 14 electrons.

In level 1 there is only one sub-level, which will be the s. In level 2 there are 2 sub-levels, the s and the p. At level 3 there are 3 sub-levels s, p and d. And at level 4 there are 4 sub-levels, the s, the p, the d and the f.

<h3>Maximum number of electrons in the third electron</h3>

At level 3 there are 3 sub-levels s, p and d.

On the other hand, in the sub-level s there can only be a maximum of 2 electrons, in p there can be a maximum of 6 electrons and in the sub-level d 10 electrons.

Then, the maximum number of electrons in the third electron can be calculated as:

2 electrons + 6 electrons + 10 electrons= 18 electrons

Finally, the maximum number of electrons in the third electron is 18 electrons.
