how much work does an elephant do while moving a circus wagon 23 meters with a pulling force of 250N at an angle of 38 degrees?
Yuki888 [10]

Answer:

The work done on the wagon is, W = 4531 J

Explanation:

Given data,

The displacement of the circus wagon, S = 23 m

The elephant pulled with a force, Fₐ = 250 N

The angle of direction of force with the horizontal, Ф = 38°

Therefore, the force in the horizontal direction is,

                                       F = Fₐ Cos Ф

The work done on the wagon is

                                       W = F · S

                                            = Fₐ Cos Ф · S

                                            = Fₐ · S · Cos Ф

                                             = 250 · 23 · Cos 38°

                                              = 4531 J

Hence, the work done on the wagon is, W = 4531 J

Mila [183]

Given :

A rope 6m long is fixed at one end, the other end is attached to a light string so that it is free to move.

The speed of waves on the rope is 18 m/s.

To Find :

The frequency of the second harmonic.

Solution :

We know, for second harmonic wave :

Wavelength = Length of rope

\lambda = L\\\\\lambda = 6 \ m

Now, we know frequency is given by :

Frequency = \dfrac{Speed}{Wavelenght}\\\\f = \dfrac{18 \ m/s}{6\ m}\\\\f = 3 \ s^{-1}

Therefore, the frequency of the second harmonic is 3 s⁻¹.
