Answer:
1 . a) the poles
2. a) earth poles.
3. b) attraction.
4. a) magnetite.
5. a) domains.
Explanation:
The magnetic field is strongest at the poles and very weak at the center of the magnet.
The magnetic compass will always align along the north - south poles of the earth. North of the compass needle is attracted towards the magnetic south pole of the earth.
Magnetic Field lines begin at the north pole of the magnet and end at the south pole. Unlike poles attract and like poles repel , so they curve for unlike poles.
Magnetite is a magnetic mineral, which is present in the animal brains , enabling them to identify correct directions.
Magnetic domains are regions where individual magnetic moments of the atoms are aligned in a definite direction.

Ultraviolet light has a shorter wavelength and higher frequency than infrared light. It also has more energy. Violet light, which is part of the ultraviolet spectrum, has a higher frequency and shorter wavelength than red light. Infrared radiation, on the other hand, has longer wavelengths and lower frequencies than violet light.
Ultraviolet light and infrared light are both forms of electromagnetic radiation, but they differ in terms of wavelength, frequency, and energy. Ultraviolet light has a shorter wavelength and higher frequency compared to infrared light. As a result, ultraviolet light has more energy than infrared light.
For example, violet light, which is part of the ultraviolet spectrum, has a higher frequency and shorter wavelength than red light. Ultraviolet radiation extends from about 400 nm to 10 nm and is produced by atomic and molecular motions and electronic transitions. In contrast, infrared radiation has longer wavelengths and lower frequencies than violet light.
It's important to note that shorter-wavelength ultraviolet light can cause damage to living cells and is better able to cause materials to fluoresce compared to visible light. On the other hand, infrared radiation is often associated with heat and is used for various purposes, such as remote control communication and thermal imaging.

45 kg * 9.8 m/s^2 = 441 N.
Answer:
The force of a mass's weight is defined as its mass * acceleration due to gravity.
On Earth, g is about 9.8 m/s^2. This will be the acceleration due to gravity.
Then, 45 kg * 9.8 m/s^2 = 441 N.
B. Proton
C. Molecule
D. Atom
The particle which is transferred from one object to another to create a static charge is the electron.
An element is a substance which cannot be split into simpler units by ordinary process.

Stars are powered by nuclear fusion in their cores, mostly converting hydrogen into helium. The production of new elements via nuclear reactions is called nucleosynthesis. A star's mass determines what other type of nucleosynthesis occurs in its core (or during explosive changes in its life cycle).
A heavy object falls with the acceleration as a light object during free fall because of acceleration due to gravity.
Explanation:
A motion can be termed as free fall when the object is completely under the influence of gravity. So in this case, no other force will be acting on the object other than the gravitational force. As the gravity influences the object in free fall, the acceleration attained by any object in free fall is same. And this acceleration is termed as acceleration due to gravity. Since, the gravity gives the acceleration to every object experiencing free fall, then the acceleration should be constant. Thus, a heavy object and a light object will have same acceleration during free fall.
