Determinar el número de plantas de lulo que se quieren establecer en 5 hectáreas si la distancia de siembra a implementar es de 140 cm entre plantas y 3 metros entre surcos.
Calcular la cantidad de bultos de 50 k de fertilizante que se debe comprar para una primera
fertilización, donde se le aplicara por planta 70 gramos.

Amass of 1.5 kg of air at 120 kpa and 24°c is contained in a gas-tight, frictionless piston-cylinder device. the air is now compressed to a final pressure of 720 kpa. during the process, heat is transferred from the air such that the temperature inside the cylinder remains constant. calculate the boundary work input during this process.

Most leaks in reciprocating air compressors can be detected and minimized by: (clo4) a)-detecting leakage areas using ultrasonic acoustic detector. b)-tightening joints and connections c)-replacing faulty equipment d)-all of the given options

The sum of the normal stresses does not change as the stress state rotates through an angle. a)-trune b)- false
