Explanation:
Science says that youngest rock can be found in between ocean .
So plates should move away from each other to form ocean .
Option C is correct
Answer:
Air drying
Explanation:
Sanitation is the set of measures that aims to preserve or modify the conditions of the environment in order to prevent diseases and promote health, improve the quality of life of the population and the productivity of the individual and facilitate economic activity. Basic sanitation is a right guaranteed by the Constitution as the set of services, infrastructure and operational installations for water supply, sanitary sewage, urban cleaning, urban drainage, solid waste and rainwater management.
Sanitation can be carried out in several ways, except for dry air, as this would damage the quality of sanitation and the environment.
Sanitation is important in treated water, sewage collection and treatment services lead to an improvement in the quality of people's lives, especially in child health, with a reduction in child mortality, improvements in education, in the expansion of tourism, in the valuation of properties, in income of the worker, in the cleaning of rivers and preservation of water resources, etc.
Answer:
D = 18000 kg/m3
V = 2.5*10{-7}m3
Explanation:
From the Archimedes principle,
Weight of fluid displaced = W_{air} - W_{water}
W_{air} = 4.5 gm
W_{water} = 4.25 gm
![W = [4.5 - 4.25]*9.81*10^{-3}](https://tex.z-dn.net/?f=W%20%3D%20%5B4.5%20-%204.25%5D%2A9.81%2A10%5E%7B-3%7D)
W = 2.4525*10{-3} N
D = 18000 kg/m3
b) object Volume can be obtained as ,
V = 2.5*10{-7}m3
<h2>K.E/P.E = m/k tan²φ x ω²</h2>
Explanation:
The given position of block x = x₀ cos(ωt + φ)
The velocity of block v = dx/dt = - x₀ sin(ωt + φ) x ω
The kinetic energy = 1/2 mv² = 1/2 m x₀² sin²(ωt + φ) x ω²
The potential energy of spring = 1/2 k x² , where k is the spring constant
Thus P.E = 1/2 x k x x₀² cos²(ωt + φ)
When t = 0
K.E = 1/2 m x₀²sin²φ x ω²
P.E = 1/2 k x₀² cos²φ
Dividing these , we have
K.E/P.E = m/k tan²φ x ω²
Answer:
Velocity v= 12.25 
Explanation:
The first rock dropped give the distance Y in meters
Now the motion of the second rock the time change so to know the velocity
