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.

Two charges of 5 x 10-6 C are a certain distance apart. These two positive charges experience 3.6 N of repelling electrical force between them. How far apart are these charges?
Answers
Answer:
r = 0.2499 m
Explanation:
Use Coulomb's Law: [tex]F_{e} = kq_{1}q_{2} / r^{2}[/tex] where Fe is the electric force, q1 and q2 are the 2 charges respectively, k is a constant (8.99*10^9 N • m^2 / C^2) and r is the distance.
[tex]3.6 N = (8.99*10^{9})(5*10^{-6})(5*10^{-6}) / r^{2}[/tex]
r = 0.2499 m
The distance that should be apart from these charges should be considered when the r = 0.2499 m.
Calculation of the distance apart:Since
Two charges of 5 x 10-6 C are a certain distance apart. These two positive charges experience 3.6 N of repelling electrical force between them
So
here we use Columb law
Electric force = k * two charges * two charges)r^2
3.6 N = (8.99*10^9) * ( 5 * 10^-6) * (5*10^-6)r^2
r = 0.2499 m.
Hence, The distance that should be apart from these charges should be considered when the r = 0.2499 m.

Explanation:
1.) Regeneration is the natural process of replacing or restoring damaged or missing cells, tissues, organs, and even entire body parts to full function in plants and animals.2.) When noise is added to analogue signals, it usually sounds like background hiss. Such noise can not be removed so the original clean signal can not be re-created or re-generated.

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?
Answers
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]

If the area of a concrete slap weighing 300n is 400cm2 ,how much pressure can it apply when kept on the ground
Answers
Answer:
7500 N/m²
Explanation:
From the question given above, the following data were obtained:
Force (F) = 300 N
Area (A) = 400 cm²
Pressure (P) =?
Next, we shall convert 400 cm² to m². This can be obtained as follow:
1×10⁴ cm² = 1 m²
Therefore,
400 cm² = 400 cm² × 1 m² / 1×10⁴ cm²
400 cm² = 0.04 m²
Finally, we shall determine the pressure. This can be obtained as follow:
Force (F) = 300 N
Area (A) = 0.04 m²
Pressure (P) =?
P = F/A
P = 300 / 0.04
P = 7500 N/m²

What's the name of the compound Cal2?
Answers
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.

A 50kg gymnast is bouncing on a trampoline. If she is going down at 5m/s when she lands on the trampoline, and it bouncesher up in the opposite direction at a velocity of 4m/s, whatis her change in momentum?
Answers
Answer:
450 kgm/s upward
Explanation:
From the question,
Change in monentum = mass× change in velocity
ΔM = mΔv....................... Equation 1
ΔM = m(v-u).................. Equation 2
Where ΔM = Change in momentum, m = mass of the gymnast, v = final velocity, u = initial velocity
Given: m = 50 kg, v = -4 m/s. u = 5 m/s
Substitute these values into equation 2
ΔM = 50(-4-5)
ΔM = 50(-9)
ΔM = -450 kgm/s
Hence the change in momentum of the gymnast is 450 kgm/s upward

HELP!!! I MIGHT FAIL THE 6th GRADE IF I DON'T GET HELP!!!! The southern United States experiences periodic occurrences of severe cold and drought conditions. Which weather phenomenon most likely causes this and why?
Answers
Answer:
La Niña, because the jet stream is displaced northwards
Explanation:
La Nina is known to be a cool phase that affects the average ocean temperature. During this period the surface wind becomes stronger and there is lesser rainfall over the areas of the central tropical Pacific to which the Southern United States belongs.
Hence, when the southern United States experiences periodic occurrences of severe cold and drought conditions, the weather phenomenon most likely causes this and why is "La Niña, because the jet stream is displaced northwards."
