A related type of beta decay actually decreases the atomic number of the nucleus when a proton becomes a neutron. Due to charge conservation, this type of beta decay involves the release of a charged particle called a “positron” that looks and acts like an electron but has a positive charge.
Answer:
A precipitate is a solid that separates out of a liquid solution when it is supersaturated (insoluble). This is a chemical change.
Explanation:
Precipitation is when a chemical substance converts into a solid from a solution by converting the substance into an insoluble form or a super-saturated solution. When the reaction occurs in a liquid solution, the solid formed is called the precipitate.
Hope that helps.
Refraction is the bending of a wave disturbance as it passes at an angle from one medium into another
Answer: magnet, motor
Explanation :
Hans Christian Orsted was the scientist who gives the relation between electricity and magnetism. He found that the magnetic needle gets deflected on the application of electric current to the circuit.
He observed that the current carrying wire acted like a magnet.
In 1821 Michael Faraday understands Orsted's work and invented electric motor. An electric motor is a device which is used to convert electrical energy to mechanical energy.
Answer:
Technician A and B are correct
Explanation:
Technician A is correct because the system app is used to calculate the amount of fuel required to go with the airflow.
Technician B is correct because Maf is incorporated with a sensor for detecting the amount of airflow.
