part one:
a crate is pulled by a force (parallel to the
incline) up a rough incline. the crate has an
initial speed shown in the figure below. the
crate is pulled a distance of 5.59 m on the
incline by a 150 n force.
the acceleration of gravity is 9.8 m/s^2
a) what is the change in kinetic energy of
the crate?
answer in units of j.

part two:
b.)what is the speed of the crate after it is
pulled the 5.59 m?
answer in units of m/s.

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.

electrical potential energy =0.072 j

explanation:

electrical potential energy is given by

u= q δv

q= charge=6 c

δv= potential difference and is given by

δv= e d

e= electric field

d= distance=5 mm=0.005 m

δv=2.4 (0.005)=0.012 v

now electric potential energy= u= q δv

u=6 (0.012)

u=0.072 j
