A 20-Kg child is on a swing attached to 3.0 m-long chains. The child swings back and forth, swinging out to a 60-degree angle. (
kvv77 [185]

Answer:

 v = 29.4 m / s

Explanation:

For this exercise we can use the conservation of mechanical energy

Lowest starting point.

          Em₀ = K = ½ m v²

final point. Higher

          Em_{f} = U = m g h

Let's use trigonometry to lock her up

          cos 60 = y / L

          y = L cos 60

Height is the initial length minus the length at the maximum angle

           h = L - L cos 60

           h = L (1- cos 60)

energy is conserved

         Em₀ = Em_{f}

          ½ m v² = mgL (1 - cos 60)

         v = 2g L (1- cos 60)

 

let's calculate

          v² = 2 9.8 3.0 (1- cos 60)

          v = 29.4 m / s

3.50 µf capacitor has a charge with a magnitude of 4.50 µC on each parallel plate. Find the potential difference between the pla
n200080 [17]

Answer:

b) 1.29 V

Explanation:

Potential Difference: This is the work done when one coulomb of charge moves from one point to another in an electric field

The expression for the potential difference is

Q = CV .................... Equation 1

Where Q = amount of charge, C = Capacitance of the capacitor, V = potential difference.

Making V the subject of the equation,

V = Q/C................. Equation 2

Given: Q = 4.5  µC = 4.5×10⁻⁶ C, C = 3.5  µF = 3.5×10⁻⁶ F

Substituting into equation 2

V = 4.5×10⁻⁶ /3.5×10⁻⁶

V = 1.2857 V

V ≈ 1.29 V.

Hence the right option is  b) 1.29 V
