The student thinks that two magnets on top of each other will produce a
magnetic field that is stronger than the magnetic field from a single magnet.
The student has a metre rule and more magnets available.
Describe how the student could develop this investigation to test this theory.
Answer:
People have been aware of magnets and magnetism for thousands of years. The earliest records date back to ancient times, particularly in the region of Asia Minor called Magnesia-the name of this region is the source of words like magnet. Magnetic rocks found in Magnesia, which is now part of western Turkey, stimulated interest during ancient times. When humans first discovered magnetic rocks, they likely found that certain parts of these rocks attracted bits of iron or other magnetic rocks more strongly than other parts. These areas are called the poles of a magnet. A magnetic pole is the part of a magnet that exerts the strongest force on other magnets or magnetic material, such as iron. For example, the poles of the bar magnet shown in Figure 20.2 are where the paper clips are concentrated.
In what ways does the loss of Arctic ice affect biodiversity of the species in the region?
There are many technologies that reduce the amount of carbon emissions into our atmosphere. Identify some example of these technologies.
With less ice, it could greatly affect the animals that depend on the ice, such as polar bears, walruses, and many other animals. This could result in their species eventually going extinct.
Another child is on a swing next to the first. This child has a mass of 48 kg and a maximum kinetic energy of 3800 J. What is the velocity of this child?
Answer:12.583m/s
Explanation:
[tex]KE=\frac{1}{2}mv^{2}[/tex]
[tex]3800=\frac{1}{2}(48)v^{2}[/tex]
[tex]\frac{3800}{24}=v^{2}[/tex]
[tex]\sqrt{158.33} = v\\12.583m/s=v[/tex]
a hot iron bar is placed 100ml 22C water. the water temperature rises to 32C. how much heat did the water gain and how much heat did the iron bar lose? Q=change T x C x M
Answer:
Water gained: 10Iron lost: -10Explanation:
Given: Hot iron bar is placed 100ml 22C water, the water temperature rises to 32C
To find: How much heat the water gain, how much heat did the iron bar lost
Formula:Q = change T x C x M
Solve:
How much heat water gained
Initial heat = 22, then rose to 32. To find how much heat the water gained, simply subtract the current heat by the initial heat.
32 - 22 = 10
The water gained 10 amounts of heat.
How much heat Iron lost
Current heat = 32, then dropped to 22. To find how much heat the Iron lost, simply subtract the initial heat by the current heat.
22 - 32 = -10
The Iron lost -10 amounts of water.

Answer:
the vertical component of the force is 43.30 N.
Explanation:
Given;
angle of inclination of the force, θ = 60⁰
magnitude of the force, F = 50 N
The vertical component of the force is calculated as follows;
[tex]F_y = F \times sin(\theta}\\\\F_y = 50 N \times sin(60)\\\\F_y = 50 N \times \frac{\sqrt{3} }{2} \\\\F_y = 25\sqrt{3} \ N\\\\F_y = 43.30 \ N[/tex]
Therefore, the vertical component of the force is 43.30 N.
The local newspaper has published the passage below. Last week, scientists released incredible images of aurora australis, known as the northern lights, as seen from the Hubble telescope. The Hubble telescope was placed in orbit in 1990 by the space shuttle and has since delivered the sharpest images we have of our planet, our galaxy, and the universe. The images delivered last week show the beautiful display of lights in the southern hemisphere. These lights are the result of the solar activity known as solar wind. Traces of solar wind reach well beyond Earth and have been detected as far as Saturn. Which statement in the news passage above is inaccurate
Answer:
The statement as aurora australis known as northern lights is incorrect. As the designation of aurora australis is for the southern lights i.e. which occur in the southern hemisphere.
Explanation:
Aurora or natural lights is a phenomenon that occurs at the poles of the Earth due to interaction between the Earth's magnetic field and cosmic rays. This interaction results in the beautiful display of colors on both poles. These are named, aurora borealis or aurora australis depending on their geographical location. If they occur on the northern pole they are termed as aurora borealis while those occurring on the southern pole are named aurora australis.
Answer:
C. The aurora australis is known as the northern lights.

What does it take to be classified as a rouge wave
Answer: A 'rogue wave' is large, unexpected, and dangerous.
At the time, surface winds were light at 15 knots. ... Most reports of extreme storm waves say they look like "walls of water." They are often steep-sided with unusually deep troughs.
Explanation:
Answer:
Rogues, called 'extreme storm waves' by scientists, are those waves which are greater than twice the size of surrounding waves, are very unpredictable, and often come unexpectedly from directions other than prevailing wind and waves.

How are proton and electron associated?The number of protons within the nucleus of the atom is identical to the atomic range. The variety of electrons in an impartial atom is identical to the number of protons. The mass range of the atom (M) is equal to the sum of the wide variety of protons and neutrons inside the nucleus.
Protons definitely charged subatomic particles that live in the nucleus. Neutrons: Neutrally charged subatomic particles that are living in the nucleus. Electrons: Negatively charged subatomic debris found inside the electron shells surrounding the nucleus.
An electron is a negatively charged factor of an atom while the proton is an undoubtedly charged frame. The electrons are present out of doors the nucleus inside the orbiting shells. But the protons alongside neutrons shape the nucleus of the atom and are gifted in the middle of the atomic nuclei.
