The visible light has wavelength in therange 400 - 700 nano-meters. The wavelengths longer than visible light are: 1-Infrared waves (used in ringtone/mobile waves)2-microwaves -used to heat and cook food. 3- Radiowaves - used in communication
Answer:
The work done against friction is the work done on an object that overcomes this frictional force allowing the object to move - it doesn't include any extra work used to accelerate an object for example - only the work used to beat the frictional force.
Explanation:
a = Δv ÷ t
t = 5 seconds
Δv = v2 - v1
v2 = 0 m/s
v1 = 54 ÷ 3.6 = 15 m/s ----> a = (0 - 15) ÷ 5 = -15 ÷ 5 = -3 m/s²
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.
Some rewards are 2.33 miles in a hour so you have to move in 700 degrees to get the system moving faster soo 700+ 2.33 divide by 3
