Answer:
starburst
Explanation:
There are many different kinds of "hazard symbols," which are being used in order for people to recognize what kind of material they are handling. When it comes to "pictograms," the symbol for a hazard class of explosive is an exploding bomb that shows a<em> starburst effect.</em> An example of such chemical is the <em>"organic peroxide" </em>and other<u> self-reactive chemicals.</u>
A "flame" is a hazard symbol for<em> flammable substances</em>. A<em> </em>"gas cylinder" is a hazard symbol for <em>gases that are located in containers that are under pressure.</em> A "test tube" is a hazard symbol for <em>substances/materials that cause corrosion to skin.</em>
Answer:
F=1.47 KN
Explanation:
Given that
Diameter of plate = 25 cm
Height of pool h = 3 m
We know that force can be given as
F= P x A
P=ρ x g x h
Now by putting the values
P=1000 x 10 x 3
P= 30 KPa
F= 30 x 0.049 KN
F=1.47 KN
So the force on the plate will be 1.47 KN.
