Answer:
9090.90 Km/s
Explanation:
Given:
hydrogen has a spectral line at = 165 nm
Line is observed at = 170 nm
Now, from the Hubble's law
Where,
v is the velocity
Δλ = Change in wavelength = 170 - 165 = 5 nm
λ = Actual wavelength
C is the speed of the light
on substituting the respective values, we get
or
v = 90.90909 × 10⁵ m/s
or
v = 9090.90 Km/s
The islands are located in the eastern Pacific Ocean, 973 km (605 mi) off the west coast of South America. The closest land mass is that of mainland Ecuador<span>, the country to which they belong, 926 km/500 nmi to the east.

The entire Earth is influenced by energy from the sun.
No I don’t because the middle eastern did way worse
Daily human activities impact the ecosystem in innumerable ways. Human activities that pollute or disrupt the environment and the ecosystem are most common such as driving a car, or using a chemical product that pollutes the environment, throwing a way trash, littering etc. Humans also can interact with the ecosystem in positive ways by learning and engaging with nature in a way that leaves no harm such as observing birds or going on a hike. In addition humans can impact the ecosystem around them by hunting or killing animal species or plant life in the areas surrounding them which generally has a negative impact on the ecosystem.
