Answer:
Moment=Force x Pivot
Explanation:
A moment is the turning effect of a force. Moments act about a point in a clockwise or anticlockwise direction.
Law of moments:
When an object is balanced (in equilibrium) the sum of the clockwise moments is equal to the sum of the anticlockwise moments.
How to calculate moments:
Moment=Force x Pivot

Answer:
L2 add a for NAL add a 2 then for the first NA2 put a 4 and then the second NA2 put a 2 and it should be good
Explanation:
Answer:
ν = 120 m / s
Explanation:
∴ λ = 12 m
∴ f = 10 Hz
∴ Hz ≡ 1 / seg (s)
⇒ f = 10 / s
∴ ν = λ * f
⇒ ν = ( 12 m ) * ( 10 / s )
⇒ ν = 120 m / s
Answer:
When an electron absorbs energy, it jumps to a higher orbital. This is called an excited state. An electron in an excited state can release energy and 'fall' to a lower state. When it does, the electron releases a photon of electromagnetic energy.
