The exact definition of technology is: The application of scientific knowledge for practical purposes, especially in industry.
The way I would put it is that technology isn’t just electronics, smartphones, and flying cars. Technology is information that people reveal and figure out and this is why it advances. You hear all the time the “advances in technology” and it’s a term that has grown rapidly. It helps businesses to progress, it’s taught people, it’s in some ways beneficial to people’s lives. It has many meanings and really that is technology simply put.
Answer:
0.01 m
Explanation:
Since the speed of light is 3.0×10^8 m/s
Use the equation,
Wavelength = speed ÷ frequency
Wavelength = 3.0×10^8 ÷ 3×10^10
Wavelength = 0.01m
Answer:
Sound waves are pushed closer together, decreasing wavelength
and increasing frequency.
125/5 = 25 meters per second
Answer:
Force plane exert on pilot = 4270 N
Explanation:
first convert radius and speed to ms
using formula from force we know that
mass = weight/ gravity = 700 N/ 9.8N/kg= 71.4 kg
Fc= N-mg
N= Fc+ mg As Fc = mv²/R
N= mv²/R + mg
taking m common
N= m( v²/R +g)
= 71.4( (200)²/ 800 + 9.8 )
Force = 4270 N
