Answer:
Pushes and pulls refer to the force that attracts or repels certain other materials without actually touching them.
Explanation:
Pushes and pulls are the forces exerted by the magnet on certain materials around it without, actually touching them. This push and pull is exerted through a region around the magnet called its magnetic field. The strength of this push and pull force is determined by, the strength of the magnetic field. A strong push or pull force is exerted by a strong magnetic field, and in turn a strong magnet and, a weak push and pull force is exerted by a weak magnetic field and, in turn a weak magnet. A push force is a repulsion while a pull force is an attraction. When a magnetic object is in the region of the magnetic field, it either attracts or is repelled away from the source of the magnetic field.
Answer: All of our energy comes from the sun, which is our nearest star. The sun sends out huge amounts of energy through its rays every day. We call this energy solar energy or radiant energy. Without the sun, life on earth would not exist, since our planet would be totally frozen.
Answer: D. 292,338 J
This is the correct answer :)
Answer: radio waves, microwaves, infrared waves.
Explanation:
Electromagnetic spectrum increases in wavelength and decreases with frequency in the following order
Gamma ray, X ray, Ultraviolet rays, Visible light, Infrared rays, Radio waves.
Since 397nm is greater than the value of visible spectrum, this shows that radio waves, microwaves and infrared wave falls in the spectrums of the wavelength value.
