Why are bathroom tiles usually rough

Physics
1 answer:
Aleks04 [339]3 years ago
8 0
-- Bathroom tiles are usually cool, so water condenses on them
when you take a hot bath or shower in the room. 

-- The natural result is that a smooth tile would become slippery,
exactly when you're walking around with wet feet and nothing on them ...
a dangerous situation.

-- In order to circumvent this safety hazard, the tiles in the bathroom
should be rough, especially on the floor.

Sodium has an atomic mass of 23 and an atomic number of 11, so the
horrorfan [7]

Answer:

12 Neutrons

Explanation:

So the mass of sodium is 22.990. You round it up to get 23(as stated in the problem). So, <em>what exactly is atomic mass?</em>

Atomic Mass is the total amount of neutrons and protons added up to form a total mass. So when you subtract 23-11 you get 12 Neutrons.

<u>Tip: </u>Don't know if you need this but-

The neutrons and protons are typically close in number (unless it's an isotope). So say that you subtract and the numbers of protons and neutrons aren't close at all. Well if that's the case, it's probably wrong.

hope this helps!!

The lowest point in the state of Louisiana is New Orleans. The city’s elevation is 8 feet below sea level. Write the elevation o
Alex Ar [27]

Answer:

-8

Explanation:

sea level is another way of saying zero. If something is above or above sea level it is a positive integer. like a regular number. if something is below sea level it is a negative integer like negative numbers. They said 8 is the elevation but new orleans is BELOW sea level. that means the integer we are looking for is going to be a negative number. 8 is the number they told us and since it is below the sea level. The integer of new orleans that represents its elevation is -8.

A long, thin solenoid has 390 turns per meter and a radius of 1.20 cm. The current in the solenoid is increasing at a uniform ra
gtnhenbr [62]

To solve this problem it is necessary to apply the concepts related to Faraday's law and the induced emf.

By definition the induced electromotive force is defined as

\int E dl = -\frac{d\phi}{dt}

\int E dl = -(\frac{dB}{dt})A

Where,

\phi = Electric field

B = Magnetic Field

A = Area

At the theory the magnetic field is defined as,

B = \mu_0 NI

Where,

N = Number of loops

I = current

\mu_0 = Permeability constant

We know also that the cross sectional area, is the area from a circle, and the length is equal to the perimeter then

A = \pi r^2

l = 2\pi r

Replacing at the previous equation we have that

E (2\pi r) = \mu_0 n (\frac{di}{dt})(\pi R^2)

Where,

R = Radius of the solenoid

r = The distance from the axis

Re-arrange to find the current in function of time,

\frac{di}{dt} = \frac{Er}{\mu_0 NR^2}

Replacing our values we have

\frac{di}{dt} = \frac{(8.00*10^{-6})(0.0348)}{(4\pi*10^{-7})(390)(1.2*10^-2)^2}

\frac{di}{dt} = 3.94487A/s
