saveliy_v [14]3 years ago
3 0
Ammonia is a gas with molecules formed by one nitrogen atom and three hydrogen atoms joined together by three covalent bonds. The geometry of ammonia is as a result of orientation of the bonds which consists 4 pairs ( 3 pairs and one lone pair). The bonds angle between two hydrogen atoms is 107 degrees because the atoms are repelled by the lone pair of electrons on the Nitrogen atom

Select the statement that correctly lists the forces from strongest to weakest. (2 points)
Vilka [71]

Strong Nuclear force: it is the short range force and strongest fundamental force in all type of forces.

Electromagnetism: this is the force due to magnetic and electric behavior of the particles. It is moderate type of force and its range is more than Nuclear force.

Weak Nuclear Force: This force is also short range force which act between the nucleoside. But this force is also moderate type of force

Gravitational force: this force is between two point masses and least order of force. also the range of this force is upto infinite.

so the correct order of this fundamental force is

<em>strong nuclear, electromagnetism, weak nuclear, gravitational</em>

vodka [1.7K]

Answer:

Work done to pull the piano upwards is 401250 J

Explanation:

Work is done against the gravity to pull the piano upwards

So here we can say that work done is

W = mgH

here we know that

mg = 5350 N

also we know that

H = 75 m

now we have

W = 5350 \times 75

W = 401250 J
