Answer:
The pressure at this point is 0.875 mPa
Explanation:
Given that,
Flow energy = 124 L/min
Boundary to system P= 108.5 kJ/min

We need to calculate the pressure at this point
Using formula of pressure


Here, 
Where, v = velocity
Put the value into the formula




Hence, The pressure at this point is 0.875 mPa
Answer:
A
Explanation:
voltage between A and C is equal battery's voltage.
Answer:
The average magnitude of magnetic field B= 0.0433/ d Tesla
(You have not provided length of side of loop, so if you divide this value by length you will get value of magnetic field.)
Explanation:
Induced emf
where B= magnetic field
d= breadth of rectangular piece
V= velocity with which the rectangular piece = o.o6m/s
n= no of turns = 10
EMF = 26mV
since d (breadth of the frame) is not given, I will use it as a variable
EMF= n×B×d×V ------------------(1) (EMF induced due to multiple turns)
From eq 1, we get
B= (EMF)/(n d V)
B= (26 X 0.001) / (10 d 0.06)
B= 0.0433/ d Tesla
The brick, even though the brick would end up traveling faster, it most likely has a larger surface area therefore it would have more air resistance.
I think it would be B because it is matter, since it has atoms, and it contains subatomic particles, which are smaller than atoms
