Answer:

two north poles and two south poles

Explanation:

A single magnet has a north pole and a south pole. If it is broken into two pieces, then each of the two pieces will have a north pole and a south pole.

No matter how many times or into how many pieces a magnet is broken, the resulting pieces will have two poles each.

How many kj of heat are needed to completely melt 32.3 g of h2o, given that the water is at its melting point? the heat of fusio
timurjin [86]

Answer: fourth option, 10.8 kJ


Explanation:


The <em>heat of fusion</em>, also named latent heat of fusion, is the amount of heat energy required to change the state of a substance from solid to liquid (at constant pressure).


The data of the <em>heat of fusions</em> of the substances are reported in tables and they can be shown either per mole or per gram of substance.


In this case we have that the<em> heat of fusion for water </em>is reported per mole: <em>6.02 kJ/mole</em>.


The formula to calculate <em>how many kJ of heat (total heat) are needed to completely melt 32.3 g of water, given that the water is at its melting point</em> is:

  • Heat = number of moles × heat of fusion

The calculations are:

  • number of moles = mass / molar mass

        number of moles = 32.3 g / 18.015 g/mol = 1.79 mol

       

  • Heat = 1.79 mol × 6.02 kJ / mol = 10.8 kJ ← answer

1) How does the oxpecker benefit?
Bezzdna [24]

Explanation:

1)

Oxpeckers are a type of small bird that land on zebras and eat ticks and other parasites that live on the zebra's skin. The oxpeckers get food and the zebras get pest control. ... Tapeworms get food by eating the host's partly digested food, depriving the host of nutrients.

2)i. Fast Speed. Basically, we can process data that is stored in HDFS at lightning-fast speed with traditional SQL knowledge, by using Impala.

ii. No need to Move Data. ...

iii. Easy Access. ...

iv. Short Procedure. ...

v. File Format. ...

vi. Big Data. ...

vii. Relational model. ...

viii. Languages.

3) A parasite is an organism that lives on or in a host organism and gets its food from or at the expense of its host. There are three main classes of parasites that can cause disease in humans: protozoa, helminths, and ectoparasites.

In the Internet, a hostname is a domain name assigned to a host computer. ... For example, en.wikipedia.org consists of a local hostname (en) and the domain name wikipedia.org. This kind of hostname is translated into an IP address via the local hosts file, or the Domain Name System (DNS) resolver.

4) Usually, although parasites harm their hosts, it is in the parasite's best interest not to kill the host, because it relies on the host's body and body functions, such as digestion or blood circulation, to live. Some parasitic animals attack plants.

5)The pollen sticks to the hummingbird and as the hummingbird goes to another cardinal flower for food the pollen is spread. This would qualify as a mutual relationship because both of the organisms benefit from the relationship. ... These two organisms have a relationship that is known as mutualism.

6)According to Campbell, moose populations are highest in areas 40 years after a major wildfire. But habitat loss is not the only probable cause of moose decline. Tiny ticks also could be a big problem. ... Without deep snow, then predators like wolves and mountain lions have an advantage over moose.”

Deforestation Led to Decline

The reasons why wolves have seen their population decimated mainly due to the diminishing forests in North America, where many of the wolves are found. Wolves were able to live in and survive in such an environment.
