Tsunamis are most common in the Pacific Ocean Basin. The entire Pacific Ocean is ringed by areas known as subduction zones, where the tectonic plates of the earth are moving relative to one another. Subduction zones are where two or more plates are colliding and one is going underneath another.

During our phase changes lab, where did we place the thermometer?
IrinaK [193]

The thermometer must be <u>in contact with the ice/water only</u>

Explanation:

In this experiment in the lab, the aim is to measure the specific latent heat of fusion of water.

The specific latent heat of fusion of a substance is the amount of heat energy required to completely melt a certain amount of the substance, mathematically:

\lambda = \frac{Q}{m}

where

Q is the heat supplied to the substance

m is the mass of the substance

In this experiment, the aim is to measure the specific latent heat of fusion of water. In order to do that, a mix of ice/water is heated with a certain amount of heat Q, and then it is evaluated the amount of mass m that undergoes melting.

An important precaution that must be taken in this experiment is that the temperature of the water/ice mixture remains constant and equal to the melting point of ice (otherwise, part of the heat supplied to the mixture is used to increase the temperature of the water, resulting in an inaccurate measure of Q). Therefore, a thermometer must be used to check constantly the temperature, and this thermometer must be placed inside the ice/water mixture only (It should not touch the saucepan, whose temperature can be higher).

So, the correct answer is

in contact with the ice/water only

Susan uses Doppler radar to analyze wind patterns in five cities and determine how windy it is. Which statement describes how sh
andrezito [222]

Answer

Susan can process wind speed data from different regions.

Explanation

A Doppler radar is used in weather forecasting in measuring the direction and speed of objects such as drops of precipitation. It determines if the movement occurring in the atmosphere is horizontally towards or way from the radar. Susan can obtain velocity data about objects at a distance which might be water droplets thus be able to predict a coming weather

ryzh [129]

The question is incomplete, the complete question is;

Which of the following aspects of biotechnology is Not considered to be a moral or ethical issue?

a.research and testing on animals

b.cloning living material

c.reducing research cost

d.damaging the environment

Answer:

c.reducing research cost

Explanation:

Ethical issues arise when a particular course of action is at odds with the generally acceptable moral standard in the society.

Research and testing on animals is contested as an ethical issue by animal rights activists.

Cloning living material  is prohibited among some sections of society and is also being contested as an ethical issue.

Damaging the environment the environment owing to biotechnology research is generally regarded as an ethical issue.

However, reducing research cost is highly acceptable in any research. It does not pose an ethical issue.
