In the open-economy macroeconomic model, if the supply of loanable funds increases, net capital outflow
a. and the real exchange rate decrease.
b. increases and the real exchange rate decreases.
c. and the real exchange rate increase.
d. decreases and the real exchange rate increases.

option a)

Explanation:

correct option is option a)

Net capital outflow  is the net flow of funds which is being invested abroad by a country during a certain period of time .

loan able funds is the fund which the people of the country decide to save or lend out to borrow.

positive net capital outflow means outflow is more than the inflow of money.

when supply of loan able fund increases the real exchange rate decrease means net export increase.

electromagnetic shielding is the practice of reducing the electromagnetic field in a space by blocking the field with barriers made of conductive or magnetic materials. shielding is typically applied to enclosures to isolate electrical devices from their surroundings, and to cables to isolate wires from the environment through which the cable runs. electromagnetic shielding that blocks radio frequency electromagnetic radiation is also known as rf shielding.

the shielding can reduce the coupling of radio waves, electromagnetic fields and electrostatic fields. a conductive enclosure used to block electrostatic fields is also known as a faraday cage. the amount of reduction depends very much upon the material used, its thickness, the size of the shielded volume and the frequency of the fields of interest and the size, shape and orientation of apertures in a shield to an incident electromagnetic
