Answer:
B. 0 degrees
Explanation:
The magnetic flux through a certain area enclosed by a loop of wire immersed in a region with magnetic field is given by:

where
B is the strength of the magnetic field
A is the area enclosed by the coil
is the angle between the direction of the magnetic field and the direction of the normal to the coil
From the equation above, we see that the magnetic flux is maximum when

So when the field is parallel to the normal to the coil (so, when it is perpendicular to the coil), therefore when:

So, the correct option is
B. 0 degrees
Because there is no wind, rain, snow, sleet, or people to wear them down,
and no rivers, streams, or floods to cover them over.
A carbide ion is an anion of carbon atom with two carbon atoms with a triple bond connected to each other. Since this carbide ion is a negatively charged ion, in order to convert carbide ion to its neutral carbon atom, it has to give up/remove four electrons.
Gravitational potential energy can be given by the equation
PE = mgh
where m is the mass,
g is the gravitational constant 9.81 or 10 depending on rounding
and h is the height
well weight is a force equiavlent to
W= m*g
so comparing that to the potential energy equation, divide the potential energy by the height and you will get weight in Newtons
So, a concave mirror is a mirror that goes inward, thus, making a convex mirror have an outward curvature. Ex: A convex mirror is used at the front of a bus.
