A). The sun is highest in London, but will not pass the ship
for another 5 hours.
Since the sun moves from east to west, the ship must be
5 hours west of Greenwich.
Each hour of sun motion is 15° of longitude.
The ship's longitude is (5 x 15°) = 75° West.
The ship may be sailing down Columbia Boulevard
in Maple Shade, New Jersey.
B). The latitude at Buffalo's City Hall is 42.887° North.
Polaris is always within about 2/3 of a degree of that angle
above the northern horizon, when viewed from City Hall.
Choice 2) is the most appropriate.
Answer:
12 kg
Explanation:
Momentum before collision = momentum after collision
m₁ u₁ + m₂ u₂ = m₁ v₁ + m₂ v₂
After the collision, they have the same velocity, so v₁ = v₂ = v:
m₁ u₁ + m₂ u₂ = m₁ v + m₂ v
m₁ u₁ + m₂ u₂ = (m₁ + m₂) v
We know that m₁ = 6 kg, u₂ = 0 m/s, and v = u₁ / 3.
(6 kg) u₁ + m₂ (0 m/s) = (6 kg + m₂) (u₁ / 3)
(6 kg) u₁ = (6 kg + m₂) (u₁ / 3)
6 kg = (6 kg + m₂) (1/3)
18 kg = 6 kg + m₂
m₂ = 12 kg
Answer: I am getting a result around the 54,800 area, so I am selecting the 55,000 HP answer.
Answer:
Precipitate
Explanation:
When a double displacement reaction occurs, the cations and anions switch partners, resulting in the formation of two new ionic compounds AD and CB, one of products is in the solid state and forms an insoluble ionic compound called a precipitate.
