Answer:
The horizontal velocity of a projectile is constant, There is a vertical acceleration caused by gravity; its value is 9.8 m/s/s, down, The vertical velocity of a projectile changes by 9.8 m/s each second, The horizontal motion of a projectile is independent of its vertical motion.
Explanation:
Put these four parts of the electromagnetic spectrum in order from shortest to longest wavelength:
gamma, infrared, microwave, ultraviolet.
Answer:
gamma, ultraviolet. infrared, microwave
gamma, ultraviolet. infrared, microwave are the electromagnetic spectrum.
What is Electromagnetic spectrum?The range of all EM radiation types is known as the electromagnetic (EM) spectrum.
The visible light from a bulb in your home and radio waves from a radio station are two examples of electromagnetic radiation. Radiation is energy that moves and disperses as it does.
The range of electromagnetic radiation's frequencies, along with their corresponding wavelengths and photon energies, is known as the electromagnetic spectrum.
Microwaves, infrared light, ultraviolet light, X-rays, and gamma rays are the other EM radiation types that make up the electromagnetic spectrum.
Therefore, gamma, ultraviolet. infrared, microwave are the electromagnetic spectrum.
