The Neutron-to-Proton Ratio. Hope this helps Sorry if it's wrong I'm a little rusty on Physics.
D. malleability is the ability to bend or form something ? like if something is malleable you can bend it
Answer:
Magnetic field, B = 0.88 T
Explanation:
It is given that,
The dimension of rectangular surface is 2.80 cm by 3.15 cm. The area of rectangular surface is, 
Angle between the uniform magnetic field and the horizontal, 
Magnetic flux, 
Let B is the magnitude of magnetic field in which the rectangular surface is placed. It is given by :

is the angle between magnetic field and the area
Here, 


B = 0.88 T
So, the magnitude of magnetic field is 0.88 T. Hence, this is the required solution.
That would be the second law
A German Botanist named <span>Matthias Schleiden made that statement.
Hope this helps! :D</span>
