Un alambre largo que transporta una corriente de 6.00 A invierte su dirección mediante dos flexiones de ángulo recto, como se indica en la figura. La parte del alambre donde ocurre la flexión está en un campo magnético de 0.666 T confinado a una región circular con 75 cm de diámetro, como se observa. Un compañero afirma que entre más a la derecha se recorra el conductor sin salir de la región circular, este experimentará más fuerza porque se estaría exponiendo a más campo. ¿Es esta una argumentación correcta? Si los es explica por qué. Si no lo es, también explica y argumenta tu respuesta. Calcula la fuerza neta como parte de tu demostración.

How are momentum and impulse related? impulse is a whim to do something, while momentum keeps it going impulse is another name fore instantaneous momentum the impulse acting on and object is equal to the change of momentum it causes. the impulse that acts on and object is the momentum that results.

It is may 5 and you are somewhere in the northern hemisphere. if you determine that the noon sun is 51 degrees above your southern horizon, what is the latitude of your location

The frequency of vibrations of a vibrating violin string is given by f = 1 2l t ρ where l is the length of the string, t is its tension, and ρ is its linear density.† (a) find the rate of change of the frequency with respect to the following. (i) the length (when t and ρ are constant) (ii) the tension (when l and ρ are constant) (iii) the linear density (when l and t are constant) (b) the pitch of a note (how high or low the note sounds) is determined by the frequency f. (the higher the frequency, the higher the pitch.) use the signs of the derivatives in part (a) to determine what happens to the pitch of a note for the following. (i) when the effective length of a string is decreased by placing a finger on the string so a shorter portion of the string vibrates df dl 0 and l is ⇒ f is ⇒ (ii) when the tension is increased by turning a tuning peg df dt 0 and t is ⇒ f is ⇒ (iii) when the linear density is increased by switching to another string df dρ 0 and ρ is ⇒ f is ⇒
