Uma motocicleta tem velocidade inicial de 20 m/s e adquire uma aceleração constante e igual a 2m/s². Calcule sua velocidade em km/h ao percorrer 100 m. V2 = Vo2 + 2.a.ΔS

Aforce of 34n stretches a very light ideal spring 0.73 m from equilibrium, what is the force constant (spring constant) of the spring? (a) 47n/m (b) 38n/m (c) 53n/m (d) 25n/m

Zeros that follow non-zeros numbers and are also to the right of a decimal point are significant

Although longitudinal waves can travel through all media types what is the disadvantage of this type of wave transmission? a) he efficiency of he wave transmission is greatly diminished as the media becomes less dense b) the oscillation of one set of particles has a huge impact on neighboring particles c) particles become too close together as they bump into each other making it more likely to hit other particles down the line
