Two disadvantages Retooling and conversion of machines and equipment in the US would be very expensive

Some expressions in the English language would eventually be quite strange: “A miss is as good as a mile”; “Inching along…”; “Ten gallon hat”; “The whole nine yards” & etc. Advantages everything is based on 10 so its easy to switch units

2. A digital camera records each image as 8 megapixels, with each pixel transferring 14 bits of information. What is the minimum
Sholpan [36]

Given what we know, we can confirm that due to its relatively low image quality, any memory card with at least one MB will be sufficient to hold the 120 images taken.

<h3>Why is one MB enough?</h3>

The photos are taken at 8 megapixels, with each one occupying 14 bits of information. A megabit consists of one million bits of potential storage. Therefore, the 120 pictures will occupy roughly 1% of the available storage of a 1 MB memory card.


Therefore, we can confirm that due to its relatively low image quality, any memory card with at least one MB will be sufficient to hold the 120 images taken.

Describe electronegativity, and explain the trend of electronegativity in the Periodic Table
vaieri [72.5K]

Explanation:

Electronegativity is the property of an atom that attracts the shared pair of an electron to itself. There is a trend in the periodic table.

While moving down in a group, the electronegativity decreases. This is due to the reason that as we move down the number of shells added and so the electron become very far from the pull of the nucleus.

As we move across a period the electronegativity increases. This is because of the no. of charge on the nucleus increase.

A motionless mass, hung on the end of a spring and pulled 5 cm downward, is a height of 1 meter above the classroom floor. Is th
maxonik [38]

Answer:

See the explanation below

Explanation:

After the mass is pulled, you have all three types of energy; potential, kinetic and elastic. Elastic as it has extension of the spring, potential energy as the mass is one meter above the ground level, and kinetic energy as the mass is in motion.

The following are the equations for calculating the different energies.

E_{elas}=0.5*k*x^2\\where:\\k = spring constant [N/m]\\x = distance [m]\\\\E_{pot} =m*g*h\\where:\\m = mass [kg]\\g = gravity = 9.81[m/s^2]\\h = elevation [m]\\\\E_{k}=0.5*m*v^2\\where:\\m= mass [kg]\\v = velocity [m/s]

Hardness is indirectly related to: specific gravity surface roughness strength of chemical bonds weight
Zepler [3.9K]
The strength of chemical bonds would be the best answer to this question. Hardness is indirectly related to the strength of chemical bonds. Hardness is the resistance from the destruction of an object itself from a material. Hardness does not need to strength of chemical bonds in order to have this resistance.
