Answer:
It shows only the strength of seismic waves that were produced.
Explanation:
Answer : The correct options are :
2) car A and car B are moving in opposite direction.
3) car A is moving faster than the car B.
Explanation :
From the given position-time graph, we conclude that the car A shows positive slope and the car B shows negative slope. That means the object which has positive slope will move faster as compared to the object with negative slope.
In case of Car A, it is moving towards the positive direction of the position axis whereas Car B is moving towards the negative direction of the position axis which means that both cars are moving in opposite direction.
So, the car A is moving faster than the car B and both cars are moving in opposite direction.
Answer: Option (B) is the correct answer.
Explanation:
Molar mass is defined as the sum of masses of all the atoms present in a compound.
For example, atomic mass of barium is 137.32 g/mol and atomic mass of bromine is 79.90 g/mol.
Therefore, molar mass of 
will be as follows.
Molar mass = atomic mass of Ba + 
= 137.32 g/mol + 
= 297.12 g/mol
Hence, we can conclude that molar mass of [tex]BaBr_{2}[tex] is 297.12 g/mol.
