En la figura se muestra un polín, con densidad uniforme, que pesa 1600N. El polín esta sujeto de un gozne en uno de sus extremos y del otro tira una cuerda. Calcular la tensión T en la cuerda y las componentes de la fuerza en el gozne.

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.

the area between the graph and the t axis

that tool is called an altimeter which measures your altitude which can be used to tell which atmosphere you are currently in, including the stratosphere.

hope this ! : )
