-- 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.
Answer:
Gravity is an example of the force of attraction between two objects that have mass.
Answer:
11.1 cm
Explanation:
Let d be the depth upto which box dipped into water.
Volume of water displaced
.12\times .12\times d m^3\\
=.0144d
Weight of water displaced = upthrust
=.0144d\times 10^3\times g\\ [ density of water is 1000kg /m³]
=14.4dg This will act upwards.
Total downward force = 1.2 +.4 = 1.6 g
For equilibrium
1.6g = 14.4 gd
d = .111 m
=11.1 cm.
Answer:
0.75 meters per second; north
Explanation:
speed (velocity)= distance/time
15 meters= distance
20 seconds= time
15/20= 0.75 meters per second; north
