Pedro picked up and held a cube of ice in his hand and noticed that he no longer felt a difference in temperature after the ice cube melted in his hand. Which of the following statement best explains what happened? 1.Heat was transferred from Pedro’s hand to the ice increasing the temperature of the ice.
2.Heat was released from the ice cube into the air increasing the temperature of the ice.
3.Cold was transferred to Pedro’s hand from the ice increasing the temperature of the ice.
4.Heat was released from Pedro’s hand into the air melting the ice increasing the temperature of the ice.

Ablock of mass m slides on a horizontal frictionless table with an initial speed v0 . it then compresses a spring of force constant k and is brought to rest. the acceleration of gravity is 9.8 m/s2. how much is the spring compressed x from its natural length? 1) x = v0*sqrt(k/(mg)) 2) x=v0*sqrt(m/k) 3) x=v0*((mk)/g) 4) x=v0*sqrt(k/m) 5) x=v0*(m/kg) 6) x=v0*sqrt((mg)/k) 7) x=(v0)^2/(2g) 8) x=v0*(k/(mg)) 9) x=(v0)^2/(2m) 10) x=v0*((mg)/k)
