Sandstone can be classified as sedimentary rock. Hope this helps :) If you have any more questions I'm happy to try and help.
Answer:
2.72 m
Explanation:
Sound travels at a certain speed and has a frequency and wavelength. The relationship between the speed of sound (V), its frequency (f), and wavelength (λ) is the same as for all waves, it is given by the equation:
V = fλ
The speed of sound in air (V) is 334 m/s
Frequency of sound (f) = 123 Hz
Wavelength = λ
V = fλ
λ = V/f = 334/123
λ = 2.72 m
Answer:
speed
Explanation:
Given: an incomplete sentence
To fill: the blank
Solution:
Speed is not a vector quantity but a scalar quantity as it has magnitude but no direction.
Speed = Distance ÷ Time
You can calculate an <u>average</u> speed if you know both the total distance and the total time of the trip.
Average speed = Total distance ÷ Total time
Rutherford is credited for discovering the nucleus of the atom. This occurred after he performed his famous gold foil experiment - by exposing a source of alpha particles to a gold foil to see how the particles deflected against the atoms of the foil, he discovered that the observed pattern only made sense when he considered the idea of a nucleus in this situation.
