Can anyone help??!! Due tomorrow and I don’t quite understand

Statement:

Zaneta and her friend Late are visiting Paris and decide to climb the Eiffel Tower. Zaneta has a mass of 60 Kg and Kate has a mass of 50 Kg. Zaneta does 180000 J of work in climbing the 1600 steps to the top of the tower. Kate climbed 400 steps.

To find out:

a. The height of the Eiffel Tower

b. The work done by Kate

Solution:

a. Mass of Zaneta (m) = 60 Kg

Acceleration due to gravity (g) = 10 m/s²

Work done (W) = 180000 J

Let the height of the Eiffel Tower be h.

We know the formula of work, i.e., W = mgh

So, putting the given values in the above formula, we get

180000 J = 60 Kg × 10 m/s² × h

or, 180000 J = 600 Kg m/s² × h

or, h = (180000 ÷ 600) m

or, h = 300 m

So, the height of the Eiffel Tower is 300 m.

b. Mass of Kate (m) = 50 Kg

Height of each step of Eiffel Tower = (300 ÷ 1600) m = 0.1875

Height that Kate climbed up in 400 steps = (0.1875 × 400) m = 75 m

Acceleration due to gravity (g) = 10 m/s²

We know the formula of work, i.e., W = mgh

So, putting the values in the above formula, we get

W = 50 Kg × 75 m × 10 m/s²

or, W = 37500 J

Answer:

a. The Eiffel Tower is 300 m high.

b. The work done by Kate by climbing 400 steps is 37500 J.

Hope you could understand.

If you have any query feel free to ask.

absorption lines are where light has been absorbed by the atom thus you see a dip in the spectrum whereas.

emission spectra have spikes in the spectra due to atoms releasing photons at those wavelengths.
