Answer:
Ceramic coating offers good protection to the car's surface. The nano-coating can protect the car from most scratches, dirt and chemical contaminants. Ceramic coating also doesn't have any side-effects to the original paint. Ceramic coating also lasts longer than regular paint.

Answer:
1.176
Explanation:
When the bullets impact the mass they become embedded on it, it is a plastic collision, therefore momentum is conserved.
v2 * (M + mb) = v1 * mb
Where
v1: muzzle velocity of the bullet
M: mass of the bob
mb: mass of the bullet
v2: mass of the bob with the bullet after being hit
v2 = v1 * mb / (M + mb)
Upon being impacted the bob will acquire speed v2, this implies a kinetic energy. The bob will then move and raise a height h. Upon acheiving the maximum height it will have a speed of zero. At that point all kinetic energy will be converted into potential energy.
Ek = 1/2 (M + mb) * v2^2
Ep = (M + mb) * g * h
Ek = Ep
1/2 (M + mb) * v2^2 = (M + mb) * g * h
1/2 * (v1 * mb / (M + mb))^2 = g * h
1/2 * v1^2 * mb^2 / (M + mb)^2 = g * h
v1^2 = g *h * (M+ mb)^2 / (1/2 * mb^2)

The height h that it reaches is related to the length L of the pendulum arm and the angle it forms with the vertical.
h = L * (1 - cos(a))

For the 9 mm:

For the 0.44 caliber:

The ratio is 460 / 391 = 1.176
Answer:
One gallon of paint can cover about 400 square feet of wall.
18 x 15 feet is 270 feet of space.
270/400 = .675 gallons for one coat on one wall
.675 x 4 = 2.7 gallons for one coat on all walls
2.7 gallons x 2 = 5.4 gallons of paint in all
Answer:
True
Explanation:
Permanent electrical safety devices (PESD) acts as a layer of protection between the electrical worker and the hazardous voltage.
Permanent electrical safety devices (PESDs) are deployed to reduce the risks in isolating electrical energy.
Electrical safety can be improved if a worker determines a zero electrical energy state irrespective of any voltage exposure to themselves.
