Answer:
B. The temperature of object A is higher than that of object B.
Explanation:
Thermal energy always transfers from hotter object to colder one. Temperature indicates the hotness and coldness of a body. In a hotter body, molecules move faster and thus, their average kinetic energy would be greater.
If thermal energy will transfer from object A to object B, then the temperature of object A would be higher than that of object B. Also, its molecules would move faster and would have greater average kinetic energy.
C. Both NPN and PNP transistor operate in the same manner but with interchanged terminals and opposite directions of voltages and current. NPN received positive voltage to the terminal and connector. PNP receives positive voltage to the terminal, but negative to the connector.
Answer:
Final concentration of the dilute solution is 1.2M
Explanation:
Dilution formula must be applied in this case to determine the molar concentration of the dilute solution:
M concentrated . Volume concentrated = Volume diluted . M diluted
75 mL . 8 M = 500 mL . M diluted
(75 mL . 8 M) / 500 mL = M diluted
M diluted = 1.2 M
