Answer:
A. El volumen
B. La densidad.
Explanation:
A derived quantity is defined as one that has to be calculated by using two or more other measurements.
Volume is a derived quantity because it requires one to use different measurements to determine it. For instance, in the case of a cube, the length, width and height of the cube are all needed to calculate volume.
Density is also a derived quantity because it needs both volume and mass for it to be calculated.
Answer:
Inductor.
Explanation:
it is given that, the voltage across the device leads the voltage across a resistor at 500 Hz. The device that has unknown circuitry can be a inductor. For LC circuit, the voltage across the inductor leads the voltage across resistor. So, the device can be a inductor.
Given Data: Diameter 'd' = 30 cm = 0.3 m Lifting Weight 'W' = mg = 2000*9.81 N = 19,620 N Calculations: Area of the lift 'A' = <span>pi\over4*d^2=pi\over4*0.3^2=0.07 m^2

Answer: scientific laws or the laws of science are statements that describe or predict a range of natural phenomena
Explanation:
Answer: 690 W
Explanation:
A day has 24 hours, so a month has 24 × 30 = 720 hs
In a month whe spent a total of $60. 00, so per hour whe were spending
$ per hour
We know the cost of one is so dividing the money spent in an hour among this value we get:
This power delivered is constant, so every moment it is
