Answer:
27 mph
Explanation:
9:45 to 11:45 = 2 hours
odometer says you traveled 54 miles in 2 hours or 27 mph
Answer:
6.97 E 16
Explanation:
Frequency is a function of velocity of light to it's wavelength.
Mathematically written as
F = Velocity / wavelength
Velocity of light = 3 x 10^8
Wavelength =430 nm =430 x 10^-9 m
converting wavelength from nanaometer to meter we divide by 10^9
Frequency = (3 x 10^8)/(430 x10^-9) =6.97 E 16
Because noble gases has full of 8 electron in her external cell......
Answer:
In this case, the horizontal velocity of the rocket starts from the acceleration, so if its velocity drops to zero,
Explanation:
When a satellite is in orbit the most important force is the docking of gravity with the Earth
F = m a
where the acceleration is centripetal and F is the force of universal attraction
centripetal acceleration is
a = v² / r
F = m v² / r
In this case, the horizontal velocity of the rocket starts from the acceleration, so if its velocity drops to zero, the force also drops to serious and the satellite steels to Earth.
The speed of the satellite is provides the speed, by local for smaller speeds in satellite, it descends in its orbits and when the speed is amate you have the energy to stop an orb to go to a higher orbit.
Technically, this delivers a lot of energy into the Earth, but it’s
spread out over a large enough area that it doesn’t do much more than
leave footprints in a lot of gardens. A slight pulse of pressure spreads
through the North American continental crust and dissipates with little
effect. The sound of all those feet hitting the ground creates a loud,
drawn-out roar which lasts many seconds.
