A 15 kg box is given an initial push so that it slides across the floor and comes to a stop. If the coefficient of friction is 0.30 a)find the friction force
b)find the acceleration of the box. Hint: what is the net force as the box slides to a stop?c)how far will the box go if its initial speed is 3.0 m/s?

Aloop of wire is in a magnetic field such that its axis is parallel with the field direction. which of the following would result in an induced emf in the loop? choose all that apply. a loop of wire is in a magnetic field such that its axis is parallel with the field direction. which of the following would result in an induced emf in the loop? choose all that apply. moving the loop outside of the magnetic field region. spin the loop such that its axis does not consistently line up with the magnetic field direction. change the magnitude of the magnetic field. change the diameter of the loop

How many electrons does each element require in its valence shell to become stable?

Farmer a has a deep well and needs a lot of water for her animals and crops. her neighbor, farmer b, has a shallower well. he needs less water than farmer a because his farm is smaller. in years of drought, sometimes farmer b can't get any water from his wells. what can farmer b do to decrease the likelihood of his well running dry?
