What is the main function of environmental policy?
a. prevent the use of natural resources
b. reduce human impact on the environment
C. prevent nature from having a harmful effect on humans
d. reduce the use of natural resources
Please select the best answer from the choices provided

The answer is B.

Explanation:

The main agenda is to reduce human impact on the environment. Human activity can adversely affect the environment. This policy makes sure there is a healthy interaction on the environment and human things. it has some policy that has to be maintained from the human beings to reduce the effect on the environment.

The answer is B

Explanation:

a solenoid is created by wrapping a l = 90 m long wire around a hollow tube of diameter d = 4.5 cm.   the wire diameter is d = 0.9 mm.   the solenoid wire is then connected to a power supply so that a current of i = 9 a flows through the wire.

randomized variablesl = 90 m

d = 4.5 cm

d = 0.9 mm

i = 9 a                                          

write an expression for the number of turns, n, in the solenoid. you do not need to take into account the diameter of the wire in this calculation.

calculate the number of turns, n, in the solenoid.

write an expression for the length of the solenoid (l2) in terms of the diameter of the hollow tube d.

calculate the length of the solenoid (l2)   in meters.

calculate the magnitude of the magnetic field at the center of the solenoid in teslas.

explanation:

i think the answer is a, hope this : )
