Answer:
The more mass a body has the more inertia it has. If the roller coaster is moving, it will want to keep moving, along the direction of motion, unless something causes it to speed up or slow down. This resistance of the moving roller coaster to changing its velocity is another example of its inertia.
Answer:
It is a predator.
Explanation:
They eat other insects so therefore I think they're a predator.
Answer:
The ion has fewer electrons
Explanation:
As Rubidium forms a positive ion Rb⁺ the number of electrons becomes fewer for the atom.
- A positive charge on an ion indicates that the number of protons for the atom is greater than the number of electrons.
- This leaves a net positive charge on the atom.
- For a negatively charged ion, the number of electrons is more than the number of protons because they have gained additional electrons.
- In a neutral atom, the number of protons and electrons are the same.
Answer:
20% of the human body float above the surface in the dead sea.
Explanation:
Given data,
The human density after inhaling, d₁ = 945 kg/m³
The human density after exhaling, d₂ = 1020 kg/m³
Therefore the average human density, d = 982.5 kg/m³
The density of the dead sea, D = 1230 kg/m³
The percentage of density of human body to the dead sea is,
P % = (982.5 / 1230) x 100 %
= 80 %
Therefore, the human body has 80% of dead sea density.
Hence, 20% of the human body float above the surface in the dead sea.
