Un ciclista inicia una pendiente con una velocidad de 40 km/h, y, cuando llega al premio de la montaña situado en la cima, a 210 m de altitud sobre la base, su velocidad es de 28 km/h. Calcula, considerando una masa de 90 kg, el trabajo total realizado por el ciclista para ascender desde la base hasta la cima de la pendiente.

If the new moon happens on january 15th, what shape will it be on february 6th?

When a vertical beam of light passes through a transparent medium, the rate at which its intensity i decreases is proportional to i(t), where t represents the thickness of the medium (in feet). in clear seawater, the intensity 3 feet below the surface is 25% of the initial intensity i0 of the incident beam. what is the intensity of the beam "10" feet below the surface? (give your answer in terms of i0. round any constants or coefficients to five decimal places.)
