Ayuda Si al aplicar a un muelle una fuerza de 30 N provocamos que se alargue 20 cm, calcular: La fuerza habrá que aplicarle para que se alargue 45 cm. *
67.5 N
150 N
30 N
50 N

The force acting on a beam was measured under the same operating conditions and a sample of 5 data points was collected. this process was repeated by 3 observers. the pooled standard deviations of these 3 data sets was 1.21. determine the true mean force using all pooled data (with a 95% probability). the result should look like this: true mean = mean +/- margin of error

An object's buoyant force and weight mean the same thing.a. trueb. false

Avery long solenoid of inner radius 2.75 cm creates an oscillating magnetic field of the form = for this solenoid, =0.00425 t and =319 rad/s. (a)what is the maximum value of the induced electric field at a perpendicular distance 1.45 cm from the axis of the solenoid? (b) what is the maximum value of the inducted electric field at a point 5.85 cm perpendicular from the axis of the solenoid?
