Answer:
Allotropes
Explanation:
Because it is the same element the chemical conposition is the same i.e. The atoms that make the substances are identical. Allotropes can be crystalline or amorphous and sometimes they can be varied in properties.
To develop this problem we will apply the Archimedes model. As well as the definitions of Weight based on mass and acceleration. The first in turn will be considered under the relationship of Density and Volume. From the values given we have to:


Since it is in equilibrium, the weight of the object will have a reaction from the water, which will cause the sum of forces between the two objects to be zero, therefore





The value of gravity is canceled because it is a constant



The portion of the object that is submerged corresponds to 82%, while the portion that is visible, above the water level will be 18%
Answer:
2240.92365 m/s
Explanation:
= Mass of electron = 
= Speed of electron = 
= Neutrino has a momentum = 
M = total mass = 
In the x axis as the momentum is conserved

In the y axis

The resultant velocity is

The recoil speed of the nucleus is 2240.92365 m/s
Answer:
Significant digits (also called significant figures or “sig figs” for short) indicate the precision of a measurement. A number with more significant digits is more precise. For example, 8.00 cm is more precise than 8.0 cm.
