Se dispone de un alambre de nicromo de 70.0 Ω para confeccionar un calentador. ¿Cuál será su potencia si: a) se aplica a sus extremos una diferencia de potencial de 110 V, b) el alambre se corta en dos partes iguales, ¿las cuales se conectan en paralelo al enchufe de 110 V?

firearm identification is the process of analyzing the bullets and cartridge cases left at a crime scene to determine if they came from a particular firearm. marks on the bullets and cartridges may be common to every firearm of that type. these are called class characteristics.

momentum of soft ball three times less than baskey ball

weight of the box is given as

here this is placed on the inclined of angle 42 degree

now this weight will have two components one is along the incline other is perpendicular to it

so here we need to apply a force parallel to incline opposite to its component of weight

so here the component of weight is given as

here we have

so it requires 75 n force to move it upwards
