A standard door into a house rotates about a vertical axis through one side, as defined by the door's hinges. A uniform magnetic

field is parallel to the ground and perpendicular to the axis. Through what angle must the door rotate so that the magnetic flux that passes through it decreases from its maximum value to 1/4 of its maximum value?

Answer:

75.5degrees

Explanation:

Magnitude of magnetic flux= BA

If rotated through an angle= BAcos theta

= (0.25)BA=BAcos theta

= costheta= 0.25

= theta= cos^-1 0.25

=75.5degrees

How can u tell matched forces act on objects?
mamaluj [8]

Answer:If an object's speed changes, or if it changes the direction it's moving in,

then there must be forces acting on it. There is no other way for any of

these things to happen.

Once in a while, there may be a group of forces (two or more) acting on

an object, and the group of forces may turn out to be "balanced".  When

that happens, the object's speed will remain constant, and ... if the speed

is not zero ... it will continue moving in a straight line.  In that case, it's not

possible to tell by looking at it whether there are any forces acting on it
