Un niño puede nadar a una velocidad máxima de 2,4 m / s. Si nada hacia el norte lo más rápido que puede a través de un río que fluye hacia el este a 3.8 m / s, ¿cuál será su velocidad resultante? ¡Da una respuesta completa!

Next a skier is pulled by a tow rope up a frictionless ski slope that makes an angle of 15 with the horizontal. the rope moves parallel to the slope with a constant speed of 0.69 m/s. the force of the rope does 800 3 of work on the skier as the skier moves a distance of 8.4 m up the incline. (a) if the rope moved with a constant speed of 2.2 m/s how much work would the force of the rope do on the skier as the skler moved a distance of 8.4 m up the incline? at what rate is the force of the rope doing work on the skier when the rope moves with a speed of (b) 0.69 m/s and (c) 2.2 m/s?

The necleus of an atom is made up of what subatomic particles?

This is for my 8th grade science class, i really don’t understand. can someone me? , lol.
