Answer:
14.5m/s
Explanation:you had to divide 2.5s divide that by 1.8
Answer and Explanation:
We have given the expression
Dimension of 
Dimension of R which is gas constant
Dimension of temperature T 
And dimension of pressure 
Now combine dimension of

So the dimension of
and dimension P is same so there unit will also be same
From ideal gas equation we know that 

As the both P and
has same dimension so they are dimensionally constant
Evaporate
Shape
I wish there were provided answer choices. Hope this helped
Solution :
a). B at the center :

Here, one of the current is in the clockwise direction and therefore, the other current must be in the clockwise direction in order to cancel out the effect of the magnetic field that is produced by the other.
Therefore, the answer is ANTICLOCKWISE or COUNTERCLOCKWISE
b). Also, the sum of the fields must be zero.
Therefore,

So,


A
Therefore, the current in the outer wire is 24.38 ampere.
Answer: it's c or 4.0 m/s
