As the Earth rotates on it’s axis we perceive the sky differently depending on where we are. This is known as a day, where the Earths rotation controls the day/night cycle. As Earth orbits the sun our axis wobbles, thus at different times in the year different regions of the Earth can see different areas in the sky.
Hope this helps!
Now, moving the Moon closer to the Earth will increase the gravitational exertion of the satellite onto our planet. If the satellite were slightly closer, the tidal bulge would grow. Low tideswould be lower and high tideswould be higher and any low lying coastline would be flooded.
Answer:
Δp = 0.05 p
Explanation:
The moment is
p = m v
The uncertainty of the moment is
Δp = dp/dm Δm + dp/dv Δv
Like the uncertainty in the mass is zero
Δm = 0
ΔP = m Δv
We divide for the moment
Δp / p = Δv / v
They do not indicate that Δv / v = 0.05
Δp / p = 0.05
Δp = 0.05 p
In the case of a system consisting of two cars
p = m₁ v₁ + m₂ v₂
Δp = dp / dv₁ Δv₁ + dp / dv₂ Δv₂
Δp = m₁ Δv₁ + m₂ Δv₂
Δv₁ / v₁ = 0.05
Δv₁ = 0.05 v₁
Δv₂ / v₂ = 0.05
Δv₂ = 0.05 v₂
We replace
Δp = m₁ 0.05 v₁ + m₂ 0.05 v₂
Δp = 0.05 p
