Andrej [43]

Answer:

work done will be equal to 305.05 J

Explanation:

We have given force exerted F = 45 N

Angle with the horizontal \Theta =41^{\circ}

Distance moved due to exerted force d = 9.1 m

Work done is equal to W=Fcos\Theta \times d , here F is force \Theta is angle with horizontal and d is distance moved due to force

So work done W=45\times cos41^{\circ}\times 9.1=309.05J

So work done will be equal to 305.05 J

defon

Answer:

None.

Explanation:

Molecules are formed by an element's need or excess of electrons. For example, in nature oxygen generally exists as 02. Other molecules are formed via chemical reaction. The example here is the burning of gasoline. Gasoline's two main byproducts are water and carbon dioxide.

Hydrogen as an atom has one electron making it unstable. Put a second hydrogen atom next to the first and the two atoms will share electrons to fill the first energy level the atom needs to be stable.
