Awire oriented so that the current flows into the screen experiences a force that deflects downward. the direction of the magnetic field must be

a. left.
b. right.
c. down.
d. up.

b-right

Explanation:

Given

current is flowing into the screen i.e. direction

length of wire is also in direction

Force experienced is in negative y direction i.e.

Force experienced by a current carrying wire in a magnetic field experience a force is given by

where I=current

L=length of element

B=magnetic field

Direction of magnetic field must be in

as

false

explanation:

boats, things on boats luggage are way more heavy then water.

we have been given a quadratic function and we need to restrict the domain such that it becomes a one to one function.

we know that vertex of this quadratic function occurs at (5,2).

further, we know that range of this function is .

if we restrict the domain of this function to either or , it will become one to one function.

let us know find its inverse.

upon interchanging x and y, we get:

let us now solve this function for y.

hence, the inverse function would be if we restrict the domain of original function to and the inverse function would be if we restrict the domain to .
