The mass of substance consumed in g to provide a lethal dose is 62.496 g
The substance has an LD50 of 336 mg/kg. We require the number of grams of the substance that a 186 kg person would consume to reach the probable lethal dose.
So, mass of substance consumed = lethal dose × mass of person
lethal dose = 336 mg/kg and mass of person = 186 kg
mass of substance consumed = lethal dose × mass of person
mass of substance consumed = 336 mg/kg × 186 kg
mass of substance consumed = 62496 mg
Converting to g, we have
mass of substance consumed in g = 62496 mg × 1 g/1000 mg = 62.496 g
So, the mass of substance consumed in g to provide a lethal dose is 62.496 g

D.
Electromagnetic waves are received and then vibrate a speaker which produces sound waves.
Explanation:
The telephone has a receiver-transducer component that can receive electromagnetic wave - radio waves spectrum- and transform them into electric energy. This electric energy is then transformed into sound energy by a speaker. This is how we're able to listen to a phone call.
The opposite happens when we speak on the phone. The sound energy is transformed into electric energy by a microphone – the reverse of a speaker. The transducer now changes the electric energy into electromagnetic waves that travel through space to the recipient in the phone conversation.
Answer:
The pressure is 0,10 atm (or 76 mmHg)
Explanation:
Read the paper for the explanation and solution of the problem
The chemical behavior of an atoms is determine by the formation or destruction of chemical bonds. The chemical bonds are the result of the interaction of the electrons of the atoms. Chemical properties of the atoms are given by how attached are the shell electrons attached to the nucleus and how they interact with other atoms. Chemical changes are the result of exchange valence electrons of the atoms. So, <span>the answer is the atomic particle that determines the chemical behavior of an atom is the electron, because it is the particle that is active in chemical bonding.</span>
