What is the difference between a pulley and incline plane?

2 answers:

4 0

Pulley is a man made tool that helped people along tome to lift things they could not do by hand while a incline plane is like a car but flat and a machine that would let a person driving it to take thing froom one place to another.The difference is that a pulley lifts things whle a inclined plane moves supplies to another place.

A incline plane is a flat inclined surface. You can stick a rope in the pulley and pull one side and the other side will lift something! They are both simple machines! The difference is a incline plane is a ramp and things go up or down and the pulley lifts something with force of your weight!!

Hello,

The answer is option C protons and neutrons.

Reason:

The middle of the nucleus contains the protons and the neutrons which contain the positive and electrical charges which decides the element which means option C will be your answer.

If you need anymore help feel free to ask me!

Hope this helps!

Which are the hybrid orbitals of the carbon atoms in the following molecules? (a) H3C―CH3 sp sp2 sp3 (b) H3C―CH═CH2 sp sp2 sp3 (

kherson [118]

Answer:

(a) sp³ sp³

H₃C - CH₃

(b) sp³ sp²

H₃C - CH = CH₂

sp²

H₃C - C ≡ C - CH₂OH

sp sp³

(d) sp³ sp²

H₃C - CH=O

Explanation:

Alkanes or the carbons with all the single bonds are sp³ hybridized.

Alkenes or the carbons with double bond(s) are sp² hybridized.

Alkynes or the carbons with triple bond are sp hybridized.

Considering:

(a) H₃C-CH₃ , Both the carbons are bonded by single bond so both the carbons are sp³ hybridized.

Hence,

sp³ sp³

H₃C - CH₃

(b) H₃C-CH=CH₂ , The carbon of the methyl group is sp³ hybridized as it is boned via single bonds. The rest 2 carbons are sp² hybridized because they are bonded by double bond.

Hence,

sp³ sp²

H₃C - CH = CH₂

sp²

(c) H₃C-C≡C-CH₂OH , The carbons of the methyl group and alcoholic group are sp³ hybridized as it is boned via single bonds. The rest 2 carbons are sp hybridized because they are bonded by triple bond.

Hence,

sp³ sp

H₃C - C ≡ C - CH₂OH

sp sp³

(d)CH₃CH=O, The carbon of the methyl group is sp³ hybridized as it is boned via single bonds. The other carbon is sp² hybridized because it is bonded by double bond to oxygen.

Hence,

sp³ sp²

H₃C - CH=O

Which sentence describes the bond formed between two identical atoms?

Lilit [14]

The best answer is C

Since identical atoms would have the same electronegativity, thus making its electronegativity difference close to zero, if not equal to zero (O), making the bond between the two to be covalent. Thus, a chemical bond formed between two identical atoms is a covalent bond.
