Two balls are simultaneously dropped from a height of 5.0 m. How long (Tg) does it take for the balls to reach the ground? Use 10 m/s2 for the magnitude of the acceleration due to gravity. Hint: The balls are released from rest at a height of 5.0 m at time t=0s.

It is necessary to determine the specific heat of an unknown object. the mass of the object is 201.0g it is determined experimentally that it takes 15j to raise the temperature 10°c. what is the specific heat of the object? 3,020,000 j/kg ∙ k 1500 j/kg ∙ k 0.00130 j/kg ∙ k 7.46 j/kg ∙ k
