Explanation:
Question
A force of 5 N acting on a body at an Angle of 30° with horizontal direction displaces it horizontally through a distance of 6 m Calculate the work done.
\rule{250}{2}
We know : Work Done = Fs × cosθ
Where
F = Force
s = Displacement
θ = Angle Formed
Work Done = Fs × cosθ
⇒ Work Done = F × s × cosθ
⇒ Work Done = 5 × 6 × cosθ
⇒ Work Done = 30 × cosθ
Note : We will Have θ = 30° as it is given Angle Formed is equal to 30°
⇒ Work Done = 30 × cos 30°
⇒ Work Done = 30 × \rm{\dfrac{\sqrt{3}}{2}}

⇒ Work Done = 15 × √3
⇒ Work Done = 15 × 1.732
⇒ Work Done = 25.98 JExplanation:

Depression is a constant feeling of sadness and loss of interest, which stops you doing your normal activities. Different types of depression exist, with symptoms ranging from relatively minor to severe. Generally, depression does not result from a single event, but from a mix of events and factors.
