To calculate instantaneous speed, we need to divide part of the total distance traveled by time. However, we don't want to use the distance of the entire trip, because that will give us average speed.
Ummm what does this even mean I need a picture to help u
Answer: W = 294 J
Explanation: Solution:
Work is expressed as the product of force and the distance of the object.
W = Fd where F = mg
W= Fd
= mg d
= 15 kg ( 9.8 m/s²) ( 2m )
= 294 J
Answer:
1.31 m
Explanation:
The relationship between frequency and wavelength of a sound wave is
where
c is the speed of the wave
f is the frequency
is the wavelenfth
In this problem, we have
c = 343.06 m/s
f = 261.63 Hz
So we can solve the formula for the wavelength:
Answer:
In biological taxonomy, a domain (also superregnum, superkingdom, or empire) is a taxon in the highest rank of organisms, higher than a kingdom. ... The three-domain system of Carl Woese, introduced in 1990, with top-level groupings of Archaea, Bacteria, and Eukaryota domains.
