The properties of magma that determines the intensity or nature of volcanic eruptions are: (1) <em>viscosity</em>, (2)<em> temperature</em>, and (3) the <em>amount of dissolved gases</em>. Viscosity describes the flowability of a fluid and its resistance to flow. Magma with low viscosity are more fluid-like and lets gases escape.
Whenever there is a change in velocity, either due to a change in speed or a change in direction, there will be non-zero acceleration. ... Acceleration is not constant if the net force is not constant.
hope that helps! mind to mark me brainleist
The force between two celestial bodies is a Newtonian gravitational force.
It is also called Newton's law of universal gravitation. We can write it down mathematically in the following way:
We can see from this formula that gravitational force is <span>inversely proportional to the square of the distance between bodies.
The electrostatic force between two charges is Coulombs force. We can write it down like this:
</span>
This force is also inversely proportional to the square of the distance between interacting particles.
The nuclear force is a little bit more complicated. It can be expressed using the so-called Yukawa potential, which has the following form:
This interaction does not follow the inverse-square law.
The final answer should be 8.
Constructive interference occurs when two waves overlap and the resulting wave has a larger amplitude. Hence, option (2) is correct.
What is interference?
The phenomenon in which there is an overlapping between the two waves propagating in a medium is known as interference. The interference is classified into two categories namely,
- Constructive interference
- Destructive interference
Constructive interference -
It occurs when there is a superposition of the two waves such that the resulting wave has a large amplitude.
Destructive interference -
It occurs when there is a superposition of the two waves such that the resulting wave has a lower amplitude.
Thus, we can conclude that constructive interference occurs when two waves overlap and the resulting wave has a larger amplitude. Hence, option (2) is correct.

Answer:
The correct option is;
The proposal is denied, because participants will likely suffer psychological harm
Explanation:
Among the recommendations in the report on ethical research with children, it is suggested that the following should be observed by researchers;
1) Seeking consent should be a continuous process
2) Contemplate payment forms other than money to allow more discretion on child safety
3) Have two way communication with the child
4) Ask for assent of the child participating in the research
The above APA suggestions where not met by the researcher in the study.
