Iline 1
magnitude
A barge is pulled by two tugboats
shown in the following figure. One tugboat
4,000 units of force at 15° above the
AB (see the figure and the other
tugboat pulls as the barge with a
force of magnitude 5,000 units of force .
at 12° below the line AB. Thesolve the pulling
forces to their scalar components
and find the components of the
resultant force pulling on the barge e
What is the magnitude of the resultant
pull? What is the direction relative to the
line AB?

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.

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.
