Explanation:

The volume of a substance when given the density and mass can be found by using the formula

[tex]volume = \frac{mass}{density} [/tex]

From the question

mass = 420 g

density = 10.5 g/cm³

The volume is

[tex]volume = \frac{420}{10.5} \\ [/tex]

Answer:

In the eukaryotic cell, the cytosol is surrounded by the cell membrane and is part of the cytoplasm, which also comprises the mitochondria, plastids, and other organelles (but not their internal fluids and structures); the cell nucleus is separate. The cytosol is thus a liquid matrix around the organelles.

C

Explanation:

answer on khan

Mass of the cube of silver is 3,449.34 kg

First find the volume of the cube in centimeters because the density is in centimeters:

0.69 * 100 = 69 centimeters

Volume = Side * Side * Side

= 0.69 x 0.69 x 0.69

= 328,509 cm³

The density of a material is calculated by the formula:

= Mass / Volume

As you have the density already and the volume, you can get the mass:

10.5 = Mass / 328,509

Mass = 10.5 * 328,509

= 3,449,344.50 grams

A kilogram is 1,000 grams so the mass in kg is:

= 3,449,344.50 / 1,000

= 3,449.3445 kilograms

Explanation:

The primary reason that large numbers of people left Ireland in the 1840s and 1850s was MASS STARVATION.

Great Famine or Great Hunger was a period in Ireland where mass starvation, diseases, and emigration occurred between 1845 to 1852.

The Great Famine was caused by Phytophthora infestans, a disease that infests in potatoes. Though the potato infestation spread throughout Europe, it greatly affected Ireland, where 1/3 of its population was dependent on the potato crop as their primary source of food.

The loss of their primary source of food led to mass starvation, sickness, and eventual death. Others opted to leave Ireland and seek shelter and food in other countries to survive.

Most similar   -----  Lithium

Least similar   ----  Nitrogen

Explanation:

Cesium is an element on the periodic with the atomic number 133. It lies in group 1 (i.e., the alkali metals) and period 6 on the periodic table. The oxidation state of group 1 metals is +1. Cesium forms an oxide with oxygen as  [tex]Cs_2O[/tex].

The most similar compound to this chemical compound is Lithium because Lithium happens to be in the same group one metal with Cesium and forms the compound [tex]Li_2O[/tex] with the oxygen

The least similar compound nitrogen due to fact that it is an oxide that is covalent in nature and lies between-group 3 -17  to form an [tex]NO_2[/tex] with oxygen.

Answer:

The kinetic energy of the two curling stones is 320 J

Explanation:

Given;

mass of the first curling stone, m₁ = 20 kg

velocity of the first curling stone, v₁ = 4 m/s

velocity of the second curling stone, v₂ = - 4m/s

assuming the second curling stone to have equal mass with the first stone = 20 kg

The kinetic energy of the first curling stone is given by;

K.E₁ = ¹/₂m₁v₁²

K.E₁ = ¹/₂(20)(4)²

K.E₁ = 160 J

The kinetic energy of the second stone is given by;

K.E₂ = ¹/₂m₂v₂²

K.E₂ = ¹/₂ (20) (-4)²

K.E₂ = 160 J

Thus, the kinetic energy of the two curling stones is given by;

K.E = K.E₁ + K.E₂

K.E = 160 J + 160 J

K.E = 320 J

Therefore, the kinetic energy of the two curling stones is 320 J

Answer:

When plants lose more water than they can take up from the soil, they become water stressed. ... Such drought conditions certainly inhibit the growth of plants. If it goes long enough without water it will die because the plant uses water for a lot of different jobs needed to keep the plant alive, so the long-term effect is that the plant will die if the drought continues.

Explanation:

Solid particles always stick together no matter what happens unless it is changing into a liquid. If you are talking about vibration for solid particles that only applies to thermal vibratio so not A. They do not slide past each other because they are packed very tightly together. They have a definite shape and volume because they stay together unless facing heat. Hopefully this helps you :)

pls mark brainlest ;)

The statements about the particles present in her model that are true;

C and D

Particles of solids are closely packed and this feature distinguishes a solid from other forms of matter ( liquid and gas ). Solids have a definite volume and shape due to their closely packed particles.

Vibration in solids occur when solids are under thermal pressure and from her skating activity, there was no form of thermal pressure therefore solids vibrating in place would not be included in her model.

Hence we can conclude that The statements about the particles present in her model that are true; they are packed very closely together and  They cause the solid to have a definite volume and definite shape

Explanation:

It decays by beta particle emission into xenon-131. After eight days have passed, half of the atoms of any sample of iodine-131 will have decayed, and the sample will now be 50% iodine-131 and 50% xenon-131

Heavy unstable atoms will continuously emit radiation and will undergo nuclear decay to form stable products. 25 g of americium -241 will take 39 years to decay into its 6.25 g sample.

Heavy unstable nuclei undergo decay when they emit radiations of alpha, beta or gamma particles. After that they will form stable isotopes or other lighter nuclei after emitting these charged particles.

The time an unstable nuclei takes to decay into half of its initial amount is called half life time. The half life time of Americium -241 is 432 years. Thus half life time of 25 g of Am-241 is

= (25 × 432 )/241

= 44.81 years.

The decay constant k can be calculated as follows:

k = 0.693 /half life time

  = 0.693 /44.81 yrs

 = 0.015.

Now the time taken for the decay process is calculated by the following  equation:

t = 1/k log (25/6.25)

 = 1/0.015yr-1  log (25/6.25)

 = 39 years

Hence, 5 g of americium -241 will take 39 years to decay into its 6.25 g sample.

An orbital is a region in space where there is a high probability of finding an electron.

In an atom there are orbitals. Orbitals are mathematical probability functions that describe regions in space where an electron could be found according to the wave mechanical model of the atom.

In the 3p sublevel, there are three orbitals. In the 2s sublevel, there is only one orbital. In the 4f sublevel, there are seven orbitals. In the 5d sublevel, there are five orbitals. In the third principal level, there are three nine orbitals in the fifth energy level, there are 25 orbitals. Note that in principal level, there are n^2 orbitals where n is the principal energy level.
