Answer:
They developed a test for poisons in the human tissues
Explanation:
Around the 19th century, Mathieu Orfila and Robert Christison developed important tests that identified poisons in human tissues.
By so doing, they laid the foundation for what is now called forensic toxicology. This science attempts to identify poisons in human tissues especially by way of autopsies and forensic investigation.
Today forensic toxicology has expanded to include alcohol testing techniques as well as testing athletes for intake of performance enhancing substances.
<h2>Answer: remain stationary</h2>
Stationary waves (so called because they seem to be immobile) occur when two waves interfere with the <u>same frequency, amplitude but with different direction</u>, along a line with a phase difference of half wavelength.
In this kind of waves there are two types of points:
The nodes, which are points that remain motionless or stationary and do not vibrate. They are due to the destructive interference of both waves when they meet.
The antinodes, which are points that vibrate with a maximum vibration amplitude. They are due to the non-destructive interference of both waves.
According to this explanation and comparing it with the description, when this two waves pass through each other, the point P will become a node, hence<u> it will remain stationary</u>.
A code of ethics is a set of principles and rules used by individuals and organizations to govern their decision making process, as well as to distinguish right from wrong. These codes are often more complex and contextual than simple morality, acknowledging specific situations and providing guidance. Many codes of ethics also specify penalties for violations. Professional and personal codes of ethics ensure that adherents are behaving in a socially acceptable manner. Organizations with an established code of ethics usually have review processes and appeal procedures in place to guard against malicious or self-serving use of the code.
Answer:
The object will slow down
Explanation: if you are walking towards harsh wind, you will slow down because of the pressure pushing you.
When a current is established in a closed conducting loop , we use ammeter. Due to this resultant potential developed detected by voltmeter.
- When current flows through loop , it gets conducted.
- Due to this Electric field is generated . This happens due to induced magnetic field.
- The free electrons were at rest until current is there , still ammeter detects some deflection.
- This deflection is due to zero current.
- Due to magnetic field , current in coil changes.
- Mathematically,
- The presence of conducting loop is not necessary for having electric field.
