Explanation:
The left ventricle relaxes and fills up with blood before squeezing and pumping the oxygen-rich blood through the aortic valve into the aorta — the main artery that carries blood to your body.<u>TRUE</u>
Steel tray because steel is an iron-carbon alloy
Answer:
The mmf required is 
×
A
Explanation:
The Magnetomotive force (mmf) is given by the formula below
where 
is the Magnetomotive force (mmf)
is the Magnetic field strength
is the magnetic length
The magnetic permeability μ is given by
μ = 
Where 
is the Magnetic flux density
and is the Magnetic field strength
From the question,
= 1.2Wb/m^2
μ = 1600m
From μ =
∴
μ
× 
A/m
Now, for the Magnetomotive force (mmf)
From the question
= 1.5 m
∴ 
× × 
×
Hence, The mmf required is × A
B. it would become a liquid
