En un experimento de laboratorio los ingenieros quieren saber la temperatura en la que un cuerpo de plomo alcanza los 25,43 m de longitud cuando inicialmente se mantiene en 25,34 m
a una temperatura de 26 ºC.
Coeficiente de dilatación lineal: 29 × 10-6 ºC -1

their crystal patterns have been disrupted by stress

the small 0.38-kg slider is known to move from position a to position b along the vertical-plane slot. determine (a) the work done on the body by its weight and (b) the work done on the body by the spring. the distance r = 0.70 m, the spring modulus k = 154 n/m, and the unstretched length of the spring is 0.53 m

explanation:

-reverse card

the speed of the cart after 3 seconds of low fan speed is ⇒ 54.0 cm/s.

the speed of the cart after 5 seconds of medium fan speed is ⇒ 120.0 cm/s.

the speed of the cart after 2 seconds of high fan speed is ⇒ 64.0 cm/s. 

just did the lab.
