Answer:
How to find the maximum height of a projectile?
if α = 90°, then the formula simplifies to: hmax = h + V₀² / (2 * g) and the time of flight is the longest. ...
if α = 45°, then the equation may be written as: ...
if α = 0°, then vertical velocity is equal to 0 (Vy = 0), and that's the case of horizontal projectile motion.
Explanation:
Answer:
The short answer is that velocity is the speed with a direction, while speed does not have a direction.
Explanation:
Speed is how fast an object is moving. It is calculated by the displacement of space per a unit of time. Velocity is the rate at which an object changes position in a certain direction. It is calculated by the displacement of space per a unit of time in a certain direction. Velocity deals with direction, while speed does not.
Answer:
Visible light
Explanation:
Electromagnetic spectrum is the classification of the electromagnetic waves based on their frequency and wavelength. In order from the shortest to the longest wavelength, we have
Gamma rays
X-rays
Ultraviolet
Visible light
Infrared radiation
Microwaves
Radio waves
All these waves are invisible to human eye, except for the visible light part. Visible light is perceived as a different color by the human eye, depending on the wavelength of the light. In particular, we have:
Violet: 380 - 450 nm
Blue: 450 - 495 nm
Green: 495 - 570 nm
Yellow: 570 nm - 590 nm
Orange: 590 nm - 620 nm
Red: 620 nm - 750 nm
