Answer:
3.14
Explanation:
A student was comparing two samples with an equal number of carbon atoms. One sample contained only Carbon-12 atoms. One sample contained only Carbon-14 atoms, which contain two more neutrons than Carbon-12 atoms. The student measured the mass of each sample and testing the reactivity of each sample.
Required:
What would best describe the results of the investigation?
Here we have to point out the necessary character of the substance needed which are used as lightning conductor.
The substance should have the following properties:
High electricity carrying capacity and less resistant.
High melting point
The substance should have high electricity carrying capacity or the resistance is less so that the electricity generated during the lightning easily conducted to the ground
The substance should have high melting point so that during lightning the generated high temperature cannot disrupt the material.
Answer:
Alpha, beta, and gamma particles
Explanation:
A shield of aluminium can effectively block off any form of radiation be it alpha, beta or gamma particles.
Radiations are products of nuclear reactions. These radiations produced are quite harmful and injurious to life.
A thick and appropriate material must be used to block off these radiations so as to properly interact with them in an advantageous way.
A shield of aluminium, a block of lead and any material with a high thickness and density is appropriate for neutralizing these forms of radiation.
