If 1 mile = 5,280ft. how many miles are in 11,245ft

Given the following information: Mass of proton = 1.00728 amu Mass of neutron = 1.00866 amu Mass of electron = 5.486 × 10^-4 amu

lesya692 [45]

<u>Answer:</u> The nuclear binding energy of the given element is $2.938\times 10^{12}J/mol$

<u>Explanation:</u>

For the given element $_3^6\textrm{Li}$

Number of protons = 3

Number of neutrons = (6 - 3) = 3

We are given:

$m_p=1.00728amu\\m_n=1.00866amu\\A=6.015126amu$

M = mass of nucleus = $(n_p\times m_p)+(n_n\times m_n)$

$M=[(3\times 1.00728)+(3\times 1.00866)]=6.04782amu$

Calculating mass defect of the nucleus:

$\Delta m=M-A\\\Delta m=[6.04782-6.015126)]=0.032694amu=0.032694g/mol$

Converting this quantity into kg/mol, we use the conversion factor:

1 kg = 1000 g

So, $0.032694g/mol=0.032694\times 10^{-3}kg/mol$

To calculate the nuclear binding energy, we use Einstein equation, which is:

$E=\Delta mc^2$

where,

E = Nuclear binding energy = ? J/mol

$\Delta m$ = Mass defect = $0.032694\times 10^{-3}kg/mol$

c = Speed of light = $2.9979\times 10^8m/s$

Putting values in above equation, we get:

$E=0.032694\times 10^{-3}kg/mol\times (2.9979\times 10^8m/s)^2\\\\E=2.938\times 10^{12}J/mol$

Hence, the nuclear binding energy of the given element is $2.938\times 10^{12}J/mol$

Liquid Mercury has a density of 13.55 g/cm3 at room temperature (20.0 ° C).

yawa3891 [41]

Answer:

A long glass tube with one end open and the other end sealed was completely filled with mercury, then it was stood on end with the open end in a container filled with mercury.

If the tube is relatively short, it will still be filled with mercury all the way to the top. If it's long enough, the column of mercury will not reach the top. The air pressure on the surface of the mercury pool that the tube sits in is what supports the mercury. When the weight of a 1 cm^2 column of mercury is greater than the air pressure per cm^2, it can't be supported by that pressure. The top of the tube will have an almost perfect vacuum, with only a tiny amount of mercury vapor in it.

The height of a column of water or mercury that can be supported by air pressure depends on, and is proportional to, the density of the water or mercury.

How you're supposed to get the answers depends on what units are used to define 1 bar of pressure. Your textbook or lecture notes should give you the value and units of a bar. If you're supposed to look it up, you'll find a variety of different combinations, including 750.06 mm of Hg or 1019.72cm of H 2 O. That would actually give you the answers directly.

750.06 m m ≈ 0.75 m of H g

1019.72 c m ≈ 10.20 m of water

If you're supposed to calculate everything, you'll need to use 1 bar = 1 x 105 N / m 2. Then you'll have to look up the g r a v i t a t i o n constant and calculate the weight of a column of mercury or water. Note that g rams and k i l o g r a m s are units of mass, not weight, which is a force. The unit of force in the m e t r i c system is the N e w t o n. This is confusing because we measure weight in pounds, which is a force. Most of the rest of the world measures "weight" in k i l o g r a m s, which is really mass.

How is 1 bar defined for you?

If it's m m H g, just multiply that by 13.6 to get the height for a column of water.

If it's a force per unit area:

We can calculate the force (weight) of H. g using the g r a v i t a t i o n constant and the given density, then go from there."

Which best describes oogenesis?

kkurt [141]

Explanation:

Oogenesis can be defined as a process of differentiation of egg cell (ovum), into a mature ovum that further develops after fertilization. In humans, oogenesis begins in the early stage of embryonic development, during whcih primary oocyte performs meiosis I and forms secondary oocyte.

Two forces act in opposite directions on a object, and how will this affect the object’s motion?

kiruha [24]

it depends on the force of each object if there is greater force moving left than right the object is moved to the left if the forces are equal the object will not move and of the force on the right is greater than thta on the left the object therefore will move right.
