What do you hope to learn from participating in the activity you selected?
Answer:
I hope to learn the basic moves and stances of boxing. I understand that I won't be boxing with another person, but that’s OK. These exercises seem like a good starting point. I really want to understand how to put together combinations. I’ve seen professional boxers throw combinations on TV, but their hands move so quickly that I can’t catch the finer details of the sport. Maybe this will be an opportunity for me to find out more.

What's the name of the compound Cal2?
Answer:
The correct answer is calcium iodide.
Explanation:
Hope this helped Mark BRAINLIEST!!!
The compound with the chemical formula CaI₂ is called calcium iodide.
A compound is a substance formed when two or more elements chemically combine in specific proportions. It is characterized by a distinct chemical composition and properties that differ from the elements it is composed of. Compounds are held together by chemical bonds, which can be either ionic or covalent, depending on the nature of the elements involved.
Calcium Iodide (CaI₂):
Calcium iodide is an ionic compound composed of the elements calcium (Ca) and iodine (I). In this compound, calcium, which is a metal, donates two electrons to iodine, a non-metal, resulting in the formation of a calcium ion (Ca²⁺) and two iodide ions (I⁻). The ions are held together by electrostatic forces of attraction, forming a crystal lattice structure.
Calcium iodide is a white, crystalline solid that is highly soluble in water. It is commonly used in various applications, including as a catalyst in organic reactions, a source of iodine for nutritional supplements, and in the synthesis of pharmaceuticals.
Therefore, The correct answer is Calcium Iodide.

If an owl produces two pellets every 24 hours and each pellet contains the remains of 3 prey, how much does it eat in a week? A month?
The owl eats 42 prey in a week and 180 prey in a month.
To calculate how much the owl eats in a week and a month, we need to determine the number of prey consumed in each time period.
In a week:
The owl produces two pellets every 24 hours. So, in one day, it consumes 2 * 3 = 6 prey (since each pellet contains the remains of 3 prey).
In a week (7 days), the owl consumes 6 * 7 = 42 prey.
In a month:
Assuming a month has 30 days (though some months have 31 days or 28/29 days), we can calculate the number of prey consumed in a month.
In a day: 6 prey
In a month (30 days): 6 * 30 = 180 prey.
Hence, the owl eats 42 prey in a week and 180 prey in a month.

A long solenoid that has 920 turns uniformly distributed over a length of 0.380 m produces a magnetic field of magnitude 1.00 10-4 T at its center. What current is required in the windings for that to occur?
Answer: 0.0328 A
Explanation:
Given
No of turns [tex]N=920[/tex]
Length of solenoid [tex]L=0.380\ m[/tex]
Magnetic field [tex]B=10^{-4}\ T[/tex]
the magnetic field at the center of the solenoid is
[tex]\Rightarrow B=\mu nI=\mu \dfrac{N}{L}I[/tex]
Putting values we get
[tex]\Rightarrow 10^{-4}=4\pi \times 10^{-7}\times \dfrac{920}{0.380}\times I\\\\\Rightarrow I=\dfrac{0.380\times 1000}{920\times 4\pi}=0.0328\ A[/tex]

Answer:
magnetism and dipole-dipole interaction
Explanation:
Two magnets are attracting each other, one magnet is big and strong, the other is small and weak, the big magnet attracts the small magnet with a stronger force, and the attraction depends on the size of the magnet.
What is the significance of the magnet and magnetic fields?The attraction between two magnets varies, and that depends upon several factors such as the strength of the force of attraction, which determines the usefulness and functionality of magnets, for example, in industrial settings, strong magnets are often used to lift heavy loads, etc.
Hence, two magnets are attracting each other, one magnet is big and strong, the other is small and weak, the big magnet attracts the small magnet with a stronger force, and the attraction depends on the size of the magnet.

What distance separates Earth and the Sun? A 300,000 km per second B Eight light-minutes C 149 million light-seconds D One light-year
Answer:
B Eight light-minutes
Explanation:
In the case when the distance separated earth and the sun so here we orbit the sun for a 150 million km distance and the light moves would be 300,000 kilometers per second
Now divide this
= 150 million ÷ 300,000 kilometers per second
= 500 seconds
This 500 seconds represent 8 minutes and 20 seconds
Hence, option B is correct
Answer:
B) Eight light-minutes
