Explanation:
The junction rule says that the sum of the currents going into a junction must equal the sum of the currents leaving a junction. This describes the conservation of current.
Answer:
Calorimeter is used to measure heat in and represents that in units of joules per kelvin units J/˚C or kJ/K
A calorimeter is can be used to measure the amount of heat released or involved in a chemical reaction.
Whereas thermometer can only measures temperature or hotness of a substance. It cannot be used to measure the thermal rate or amount of heat energy of a reaction. Unit measurement used by thermometer is Celsius (°C).
Explanation:
Answer:
The value is 
Explanation:
From the question we are told that
Generally the average velocity of the train is mathematically represented as
substituting 82.4 km/h for u and 16.4 km/h. for v
Generally the time taken is mathematically represented as
substituting 49.4 \ km/h for v and 
converting to seconds
