block a of mass 4.0 kg is pulled along a horizontal table by a force of 15 n, which is applied
by a light string that passes over a light frictionless pulley, as shown above. the coefficient
of kinetic friction betveen the block and the surface is 0.25.
(a) on the dot below, which represents the block, draw and label the forces (not components)
that act on the block as it is pulled across the table.

layer a is the exosphere and layer b is the thermosphere.   is the answer i think but i hope this .

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.

hi,

what occurs during a solar eclipse?

there are small tides across earth.

the moon is between earth and the sun.

p.s. im not sure if the first answer is correct because during a solar ecliphse there are spring tides and i dont know if they are the same.
