Una mujer esta segando su prado con segadora eléctrica cuya cuchilla gira a 1500rpm. la mujer encuentra una zona de hierba alta e incrementa la celeridad a 2000rpm durante un intervalo de 3.40s con una aceleración angular constante. cuál es la aceleración angular? .2 cuántas revoluciónes ha realizado la cuchilla mientras estaba acelerando?

Plzz worth 22 ! which statement about energy transformations is not true? a all forms of energy can be transformed into thermal b energy is never destroyed or created during transformations c potential chemical energy always transforms into kinetic d some thermal energy is always released during a transformation

The scalar triple product computes the magnitude m of the moment of a force vector f about a specified line. it is m = (r × f) · n, where r is the position vector from the line to the point of application of the force and n is a unit vector in the direction of the line. use matlab to compute the magnitude m for the case where f = [12, −5, 4] n, r = [−3, 5, 2] m, and n = [6, 5, −7].
