Answer:
Er-144 -------> Dy-140 + He-4
Explanation:
Alpha decay is the release of a hydrogen nucleus. So the original atom will decrease the mass by 4 and the atomic number by 2.
Answer:
Bacterial cell, cell with a nucleus, multicellular organism
S waves
- The motion of the medium is perpendicular to direction of propagation of the wave
.
- They can propagate only through solids and not through gases or liquids
.
- They travel with less speed
.
P waves
- These are compression waves
.
- These waves produces a force along the direction of propagation
.
- They can propagate through solids, gases and liquids.
- P waves are smaller than s waves
.
- They travel with 60% greater speed than S waves
.
P-waves travel 60% faster than S-waves on average because the interior part of the Earth does not react the same way as the s wave and P wave.

Answer:
The answer to your question is density = 635.3 g/ml (check the units)
Explanation:
Data
density = ?
volume = 85 ml
mass = 54 kg
Density is a physical property that relates the mass of an object and its volume.
The unit of this property are g/ml or kg/m³
In this problem, I will calculate the density in g/ml
Formula
density = mass/ volume
-Substitution
density = 54000 / 85
-Simplification
density = 635.3 g/ml
