<h3>What is a database?</h3>
The term database refers to the arranging of the data that concerns clients in relevant entry point such as computers and file cabinets. This is the way by which companies are bale to keep track of their customers.
The person that is most helpful in the management of the tens of thousands of customer addresses in three different computer systems and written on paper in filing cabinets is the database administrator.

Explanation:
Momentum is conserved when there is no net external force. So momentum is conserved in the direction parallel to the incline.
p₀ = p
m v cos θ = (m + M) vₓ
vₓ = m v cos θ / (m + M)
After the collision, energy is conserved.
PE = KE
(m+M) gh = ½ (m+M) vₓ²
gh = ½ vₓ²
h = vₓ² / (2g)
d sin θ = [m v cos θ / (m + M)]² / (2g)
d = [m v cos θ / (m + M)]² / (2g sin θ)
If you stay on the same planet and drop a lot of objects one at a time,
it turns out that every object you drop falls from your hand to the ground
with the same acceleration, and hits the ground with the same speed,
no matter whether the object is light, heavy, or anything in between.
That particular value of acceleration is the "acceleration due to gravity".
On Earth, it's 9.81 meters per second². On the moon, it's 1.62 meters
per second². On Jupiter, it's 25.89 meters per second².
Why we don't generally notice it: The previous description is true if the
ONLY force on the object is the force of gravity. If it has to fall through
<u>air</u> on the way down, then the air can have a great effect on it. Many
museums have an exhibit where they drop things in a long tube with
all the air removed from it, and there you can see some pretty weird
stuff ... like a bowling ball, a rock, a sheet of paper, and a feather, all
falling together, with nothing fluttering.
<u>Why</u> everything falls with the same acceleration ? That's a separate question.
Answer:110v
Explanation:
Current=100 amperes
Resistance=1.1 ohms
voltage=current x resistance
Voltage=100 x 1.1
Voltage=110v

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
