Answer:
100 ml de una disolucion 05 M de sulfate de vivre
Answer:
2 m/s
Explanation:
Velocity is a vector quantity that is given by:
where
d is the displacement of the object (a vector indicating its change in position)
t is the time elapsed
Note that since velocity is a vector, it has both a magnitude and a direction (the same as the displacement).
For the toy train in this problem, we have:
d = 40 m (displacement)
t = 20 s (time elapsed)
So, its velocity is:
Answer:
Explanation:
Capacitance is defined as the charge divided in voltage.
Introducing a dielectric into a parallel plate capacitor decreases its electric field. Therefore, the voltage decreases, as follows:
Where k is the dielectric constant and the voltage of the capacitor without a dielectric
The capacitance with a dielectric between the capacitor plates is given by:
Where k is the dielectric constant and the capacitance of the capacitor without a dielectric. So, we have:
Therefore, a capacitor with a dielectric stores the same charge as one without a dielectric.
Answer:
Since energy can be measured as work, we can write energy = force x distance. Thus SI derived unit of energy has the units of newtons x meter or kg m2/s2.
