1) Um pesquisador adotou uma escala termométrica Y em que, para a temperatura de fusão do gelo, ele estabeleceu o valor 40° Y e, para a temperatura de ebulição da água, ele estabeleceu 120°Y. A) Certo dia, entre as 9 horas da manhã e o meio-dia, a temperatura ambiente variou e chegou a 7,5oC. Qual é o valor dessa variação de temperatura na escala Y?

A250-n box is at rest on a frictionless horizotal floor. then a person shoves the box with a non-zero force of magnitude p. which statement best describes the relationship betweeen p and the motion of the box after it was shoved? -the box will not move when p< 250n but otherwise will accelerate at a constant rate that is directly proportional to p - the box will begin moving at a speed that is directly proportional to p, then will gradually slow to a halt -the box will move with constant velocity at a speed that is directly proportional to p -box will accelerate across the floor at a constant rate that is directly proportional to p
