Can anyone ans this ..
with explanation

5 mL/min

Explanation:

Amount of water = 200 mL

Percolation time = 40min

Rate of percolation = Amount of water in mL / Percolation time in min

=200 / 40

=5 mL/min.

Hence, the rate of percolation of water through the given soil sample is 5 mL/min.

adding a(n) to an electric circuit would increase the magnetic field around a wire;

b. solenoid

a solenoid is a type of electromagnet whose purpose is to generate a controlled magnetic field.

if the purpose of the solenoid is instead to impede changes in the electric current, a solenoid can be more specifically classified as an inductor rather than an electromagnet.

a. spokes of a wheel.

as indicated in the question radial contains rad, also found in radius, so the fracture's would span the radius.
