Answer:

Yes, electrons with energy of 1.3ev will be emitted from the metal surface

Explanation:

From Eisenstein's photoelectric equation;

KE= E - Wo

Where;

KE= kinetic energy of the emitted photoelectron = ??

E= Energy of the photon =4.5 ev

Wo= work function of the metal = 3.2ev

KE= 4.5 ev - 3.2 ev

KE= 1.3 ev

Answer:

There are three main types of rocks: sedimentary, igneous, and metamorphic. Each of these rocks are formed by physical changes—such as melting, cooling, eroding, compacting, or deforming—that are part of the rock cycle. Sedimentary Rocks Sedimentary rocks are formed from pieces of other existing rock or organic material. There are three different types of sedimentary rocks: clastic, organic (biological), and chemical. Clastic sedimentary rocks, like sandstone, form from clasts, or pieces of other rock. Organic sedimentary rocks, like coal, form from hard, biological materials like plants, shells, and bones that are compressed into rock. The formation of clastic and organic rocks begins with the weathering, or breaking down, of the exposed rock into small fragments. Through the process of erosion, these fragments are removed from their source and transported by wind, water, ice, or biological activity to a new location. Once the sediment settles somewhere, and enough of it collects, the lowest layers become compacted so tightly that they form solid rock. Chemical sedimentary rocks, like limestone, halite, and flint, form from chemical precipitation. A chemical precipitate is a chemical compound—for instance, calcium carbonate, salt, and silica—that forms when the solution it is dissolved in, usually water, evaporates and leaves the compound behind. This occurs as water travels through Earth’s crust, weathering the rock and dissolving some of its minerals, transporting it elsewhere. These dissolved minerals are precipitated when the water evaporates. Metamorphic Rocks Metamorphic rocks are rocks that have been changed from their original form by immense heat or pressure. Metamorphic rocks have two classes: foliated and nonfoliated. When a rock with flat or elongated minerals is put under immense pressure, the minerals line up in layers, creating foliation. Foliation is the aligning of elongated or platy minerals, like hornblende or mica, perpendicular to the direction of pressure that is applied. An example of this transformation can be seen with granite, an igneous rock. Granite contains long and platy minerals that are not initially aligned, but when enough pressure is added, those minerals shift to all point in the same direction while getting squeezed into flat sheets. When granite undergoes this process, like at a tectonic plate boundary, it turns into gneiss (pronounced “nice”). Nonfoliated rocks are formed the same way, but they do not contain the minerals that tend to line up under pressure and thus do not have the layered appearance of foliated rocks. Sedimentary rocks like bituminous coal, limestone, and sandstone, given enough heat and pressure, can turn into nonfoliated metamorphic rocks like anthracite coal, marble, and quartzite. Nonfoliated rocks can also form by metamorphism, which happens when magma comes in contact with the surrounding rock. Igneous Rocks Igneous rocks (derived from the Latin word for fire) are formed when molten hot material cools and solidifies. Igneous rocks can also be made a couple of different ways. When they are formed inside of the earth, they are called intrusive, or plutonic, igneous rocks. If they are formed outside or on top of Earth’s crust, they are called extrusive, or volcanic, igneous rocks. Granite and diorite are examples of common intrusive rocks. They have a coarse texture with large mineral grains, indicating that they spent thousands or millions of years cooling down inside the earth, a time course that allowed large mineral crystals to grow.

Alternatively, rocks like basalt and obsidian have very small grains and a relatively fine texture. This happens because when magma erupts into lava, it cools more quickly than it would if it stayed inside the earth, giving crystals less time to form. Obsidian cools into volcanic glass so quickly when ejected that the grains are impossible to see with the naked eye. Extrusive igneous rocks can also have a vesicular, or “holey” texture. This happens when the ejected magma still has gases inside of it so when it cools, the gas bubbles are trapped and end up giving the rock a bubbly texture. An example of this would be pumice.

Answer:

the water is not warm enough for her

Explanation:

Given that

Her preferred temperature = 82°F

Thermometer in water reads = 24°C

Convert the preferred temperature to °C

°C=5/9 (82-32)

°C = 27.8 °C

Hence the water is not warm enough for her

The water is not warm enough for her to swim in.

We have to convert Emma's preferred temperature to °C

°C=  5/9 x (F - 32)

°C=5/9 (82-32)

°C = 27.8

Therefore the temperature is 27.8°C

This means that the temperature of the water is not warm enough for her

to swim in.

Answer:

Thomson passed an electric current through sealed glass tubes filled with gases. Thomson concluded that electrons must be parts of the atoms of all elements. Millikan determined the charge and mass of the electron.

Explanation:

Thompson discovered electrons and proposed the plum - pudding model of the atom. Millikan measured the charge to mass ratio of an electron.

In the early days of the atomic theory, working with his cathode ray tube, J.J Thompson discovered electrons. His discovery of electrons led him to propose a model which depicted the atom as a sphere of positive charges into which negative charges were embedded. This is the plum-pudding model of the atom.

Using his famous oil-drop experiment, R.A Millikan successfully measured the charge to mass ratio of the electron and thereby determined the magnitude of charge on the electron.

Answer:

The nonmetal atoms accept electrons and form ions with a negative charge, called anions. When an ionic compound forms, the total charge on the atoms adds up to zero. This is known as the rule of zero charge.

Explanation:

Answer:

D. The pressure of the gas on the left would double because the number of collisions would also double.

Explanation:

According to Boyle’s law, the pressure of a gas is inversely proportional to its volume.

As the number of particles was doubled in the left box, the particles have less space for movement as the volume occupied by gas particles has decreased and it will lead to the collision of gas particles with the walls of the container.

As the volume decreases as gas particles were doubled and so the pressure of the gas on the left would double.

Hence, the correct answer is "D. The pressure of the gas on the left would double because the number of collisions would also double."

Answer:

Explanation:

Explanation:

The lungs pump oxygen in and carbon dioxide out, which goes through the blood stream to help with the cell's energy needs.

Nutrients pass through the blood stream as well. The nutrients start with the digestive system (mouth, esophagus, stomach, small intestine) before going into the blood stream. The nutrients are building blocks to help make new cells when old ones die off.

When those cells die off, the body sheds them like dead skin, but internal dead cells are passed off as waste. This waste and other byproducts the body doesn't need passes through the blood stream as well.

In short, the blood stream is basically the highway to help get desired materials (eg: oxygen and nutrients) and get rid of waste (eg: carbon dioxide and other unwanted byproducts or dead cell material)

So that's why the answer includes A, B and C.

It can use a small amount of sunlight for photosynthesis

Explanation:

Seaweeds are a group of marine plants/algae that grow attached to rocks underwater. However, despite their depth underwater, they still perform photosynthesis, which is a process that requires energy from sunlight.

Seaweeds are able to perform photosynthesis underwater because they are efficient users of sunlight energy. Hence, they require only a small amount of sunlight that penetrates the ocean to perform photosynthesis.
