. particle
b starts 349 cm down the track and moves at
a constant velocity of 44 cm/s to the left.
when will they meet?
answer in units of s.

t = 4 s

Explanation:

As we know that the particle A starts from Rest with constant acceleration

So the distance moved by the particle in given time "t"

Now we know that B moves with constant speed so in the same time B will move to another distance

now we know that B is already 349 cm down the track

so if A and B will meet after time "t"

then in that case

on solving above kinematics equation we have

think its the third option

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.
