1. En una prueba de atletismo de lanzamiento de peso, el atleta logra una marca de 30 m. Sabiendo que la bola
sale de su mano a 2 m del suelo y con un ángulo de 45°, averiguar la velocidad inicial del lanzamiento.

the five characteristics of adolescence are biological growth and development, and undefined status, increased decision making, increased pressure and the search of self.

i think its c if i'm wrong

you'd use the equation that establishes a relationship between  energy  and  wavelength, which looks like this

e=h⋅cλ, where

λ  - the wavelength of the photon; c  - the speed of light, usually given as  3⋅108m/s; h  -  planck's constant, equal to  6.626⋅10−34j s

plug the value you were given for the energy of the photon in the above equation to get the wavelength

e=h⋅cλ⇒λ=h⋅ce

λ=6.626⋅10−34js⋅3⋅108ms−1.257⋅10−24j=1.581⋅10−1m

its a circle not a square that's simple silly.
