svetoff [14.1K]
A human body, just like a dog's, will sweat. Dogs will pants and sweat through the pads of their feet to cool down, and human will sweat through their foreheads, armpits, etc.
Dogs will tend to, in hot environments, lay on the floor or where the surface is cooler. Since they cannot simply strip their clothing to keep cool they tend to find cool surfaces, fans, sources of air, etc. to keep cool from the heat.

Which of the following sets of elements could replace the generic "X" symbol with their own to produce a valid dot notation for
inessss [21]

Symbol  "X" represents Nitrogen, phosphorus, and arsenic.as they have five valence electrons in their valance shell.

<h3>What is a Lewis notation?</h3>

A Lewis form is a completely simplified illustration of the valence shell electrons in a molecule. it's miles used to expose how the electrons are organized round man or woman atoms in a molecule. Electrons are proven as dots or for bonding electrons as a line between the 2 atoms.

Lewis systems, also known as electron-dot structures or electron-dot diagrams, are diagrams that show the bonding between atoms of a molecule, and the lone pairs of electrons that can exist within the molecule.A Lewis form is based totally at the idea of the octet rule, wherein atoms percentage electrons in order that every atom has 8 electrons in its outer shell. for example, an oxygen atom has six electrons in its outer shell.

An object with the mass of 2300 g has a force of 6.2 Newton's applied to it. What is the resulting acceleration of the object?
Triss [41]

Answer:

\boxed {\boxed {\sf a\approx 2.7 \ m/s^2}}

Explanation:

Force is equal to mass times acceleration.

F=m*a

By dividing both sides by m, we rearrange the formula for a (acceleration).

\frac{F}{m} =a

The force is 6.2 Newtons, but we can convert the units to make the problem easier later on.

  • A Newton is equal to 1 kg*m/s², so 6.2 N is equal to 6.2 kg*m/s².

The mass is 2300 grams, but we need to convert it to kilograms.

  • To convert grams to kilograms, divide by 1,000
  • 2300 g/1000= 2.3 kg

F= 6.2 \ kg*m/s^2\\m=2.3 \ kg

Substitute the values into the formula.

a=\frac{6.2 \ kg*m/s^2}{2.3 \ kg}

Divide. Note that the kilograms or "kg" will cancel each other out (this is why we converted the units).

a=\frac{6.2 \ m/s^2}{2.3 \ }

a=2.69565217 \ m/s^2

Round to the nearest tenth. The 9 in the hundredth place tells us to round up to 2.7

a\approx 2.7 \ m/s^2

The acceleration is about <u>2.7 meters per second squared.</u>
