un canguro puede saltar una altura maxima de 1 m, si despega con un angulo de 45° con respecto a la horizontal, ¿cual es la magnitud de la velocidad de despegue?​

Newton's law of universal gravitation states that the force f between two masses, m1 and m2, is given below, where g is a constant and d is the distance between the masses. find an equation that gives an instantaneous rate of change of f with respect to d. (assume m1 and m2 represent moving points.)

Describe different biomes. what are some adaptations that organisms (plants or animals) must have to live in each biome?
