Oil must be mined from underground.
Answer:
The ceramic tile will stand the force of 5 N.
Explanation:
Step 1: Calculate the area (A) of the ceramic tile
We will use the formula for the area of a square.
A = 50 cm × 50 cm = 2500 cm²
Step 2: Convert "A" to in²
We will use the conversion factor 1 in² = 6.45 cm².
2500 cm² × 1 in²/6.45 cm² = 3.9 × 10² in²
Step 3: Calculate the pressure (P) exerted by a force (F) of 5 N
We will use the following expression.
P = F/A
P = 5 N / 3.9 × 10² in² = 0.013 N/in²
Since the pressure exerted would be less than the maximum pressure resisted (40 N/in²), the ceramic tile will stand the force of 5 N.
The Sun --> through 93 million miles of space, in about 8 minutes --> through the Earth's atmosphere --> through the glass window into your house --> through a little more air, inside the room --> through the glass fishtank --> through some water --> light hits the fish; all colors of light except yellow get absorbed by the fish; the yellow waves bounce off --> through the water again --> through the glass tank again, out into the room --> through some air again --> a little bit of the yellow light happens to go into your eye, and you see it. Most of it doesn't, though.
publish a book in which he explained his heliocentric theory.
Explanation:
The heliocentric theory is the one according which the Sun is in the center of our Solar Sistem and the planets go around it.
Previously to this theory (before Copernicus) the prevalent theory was geocentrism accordind which it was the earth who stood in the center and all the other celestial bodies went around it.
