Answer:
The reason why the height for the liquid is 5.18 m is because, for constant pressure, height is inversely proportional to density.
Explanation:
We know that pressure, P = ρgh where ρ = density of material, g = 9.8 m/s and h = height.
Since density of liquid = 2 × density of water = 2 × 1000 kg/m = 2000 kg/m³
Since atmospheric pressure = 101500 N/m²,
The height of liquid for this pressure is h = P/ρg = 101500/(2000 × 9.8) = 5.18 m
For the same pressure, the height for water is h = P/ρg = 101500/(1000 × 9.8) = 10.36 m
Since pressure = constant,
P = ρgh ⇒ P/ρg = h since P and g are constant, h ∝ 1/ρ
ρ₁h₁ = ρ₂h₂
So, the reason why the height for the liquid is 5.18 m is because, for constant pressure, height is inversely proportional to density.
Answer:
Explanation:
Physical development refers to the growth, physical and biological changes that happens in the humans body between birth and till they get to adolescence stage. There is development in brain, senses, they way they talk, physical appearance e.r.c.
Examples of these include, as humans grow, there is an increase in the way they interact with other people.
Babies tend to interact and learn new words even as their sense organs are been developed.
Cognitive development refers to how children develop in knowledge, skills, they way they think, their disposition and problem solving ability. These help children to think and understand their environment better.
Psychosocial development entails psychological and social development and it refers to how human personality is developed, acquiring social attitudes and skills from young age to adult. It entails how humans interact with their environment.
Moral development entails changes that occur in humans from childhood to adulthood by possesing the the skills and ability to know what is right and what is wrong i.e an understanding of morals behavior.
The atom in an excited state has more energy and is less stable than the atom in the ground state.
