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:
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.

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.

Starting from rest, this airliner accelerates at 2.4m/s2 for 32 seconds before leaving the ground. Calculate its velocity at liftoff.
Answer:
The velocity will be "76.8 m/s".
Explanation:
The given values are:
Acceleration,
a = 2.4 m/s²
Time,
t = 32 seconds
By equation of motion,
⇒ [tex]v=u+at[/tex]
On substituting the values, we get
⇒ [tex]=0+2.4\times 32[/tex]
⇒ [tex]=0+76.8[/tex]
⇒ [tex]=76.8 \ m/s[/tex]

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.

Your friend tells you That there is no gravity in the space shuttle, which orbits 400 km (250 miles) above the Earth.
Do you agree or disagree? Explain
Answer:
Yes. Space is somewhat voidless. Space has no atmosphere, just planets, stars, and dark matter. Space can be said to be special. Space never ends. Gravity would cause an object to fall down. However, since space never ends, an object could continue moving forever.
At an altitude 400 km (250 miles) above the Earth, gravity is nearly 90 % as strong as on the surface of the earth.
What is the gravity of the earth?The gravity of Earth can be described as the net acceleration that is imparted to objects due to the combined effect of gravitation and centrifugal force. It can be defined as a vector quantity, whose direction coincides with a plumb bob and strength or magnitude.
In SI units gravitational acceleration is expressed in meters per second squared or equivalently in newtons per kilogram. Near Earth's surface, the gravity acceleration is approximately 9.81 m/s², ignoring the effects of air resistance.
The gravity of the earth decreases with altitude rises above the Earth's surface because of the greater distance from the Earth's center. At an altitude of 400 kilometers equivalent to an orbit of the ISS, gravity is nearly 90% as strong as at the Earth's surface.

Rutherford tracked the motion of tiny, positively charged particles shot through a thin sheet of gold foil. Some particles traveled in a straight line and some were deflected at different angles.
The question is incomplete, the complete question is;
Rutherford tracked the motion of tiny, positively charged particles shot through a thin sheet of gold foil. Some particles traveled in a straight line and some were deflected at different angles. Which statement best describes what Rutherford concluded from the motion of the particles? Some particles traveled through empty spaces between atoms and some particles were deflected by electrons. Some particles traveled through empty parts of the atom and some particles were deflected by electrons. Some particles traveled through empty spaces between atoms and some particles were deflected by small areas of high-density positive charge in atoms. Some particles traveled through empty parts of the atom and some particles were deflected by small areas of high-density positive charge in atoms.
Answer:
Some particles traveled through empty parts of the atom and some particles were deflected by small areas of high-density positive charge in atoms.
Explanation:
Rutherford first proposed the nuclear model of the atom after his landmark experiment.
In this experiment, alpha particles from a source was focused on a thin gold foil. Some of the particles passed through empty spaces within the atom but were deflected at different angles by a small area of high-density positive charge within an atom which Rutherford later called the atomic nucleus.
Hence the answer above.

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]
