Answer:
The pressure is
Explanation:
From the question we are told that
The depth of the swimming pool is
The density of water is
Generally the total pressure exerted on the bottom of the swimming pool is mathematically represented as
Here is the atmospheric pressure with value
So
=>
=>
Answer:
Explanation:
It doesn't mean it equal to each other. lets say x is directly proportional to y. Here, if something happens to x then, y will do the same thing. for example, if x increases, then y also increases. similarly, if x decreases, then y also decreases. therefore, x is something or lets say it is a major factor that decides the fate of y.
Explanation:
1)a=16m
b=28m
c=10m
volume of one box: V=16*28*10=4480m³
volume of 100 boxes: 4480*100=448000m³
2) 1960
3) 7: meter-length, kilogramme-mass, second-time, ampere-electric current, kelvin-temperature, candela-luminous intensity, mole-amount of substance
4)Area: S=a*b
Volume: V=a*b*c

Mechanical advantage is a measure of the force amplification achieved by using a tool, mechanical device or machine system.
now here we can say that mechanical advantage is given as
here we know that
output force = 156 N
input force = 52 N
so we will have
so here mechanical advantage is 3
