Answer:
please read the answer below
Explanation:
To find the electric field you can consider the Gaussian law for a cylindrical surface inside the slab.


where Qint is the charge inside the Gaussian surface, AG is the area of the surface and rho is the charge density of the slab.
By using the formula for the volume of a cylinder you obtain:

where h is the height. If you assume that the slab is in the interval (-zo<z<z0) you can write VG:

Finally, by replacing in the expression for E you get:


hence, for z>0 you obtain E=pz/eo > 0
for z<0 -> E=pz/eo < 0
Hi C is the Answer I believe
Near Earth's surface, gravitational acceleration is approximately 9.81 m/s2, which means that, ignoring the effects of air resistance, the speed of an object falling freely will increase by about 9.81 metres per second every second.
Answer:
#_pile = 12 celdas
Explanation:
Lead acid sulfur batteries generate each cell a potential of 2 volts. By colonato to reach the voltage of 24 volts
#_pile = 24/2
#_pile = 12 cledas
serially connected
A) It would likely contain all the isotopes of nickel shown in the chart in the same proportions.
