The actual size of the Solar system is too big to show without making a much smaller model. If someone wants to see the orientation of the planets a model has to be made so we can see it without flying out too space.
Answer:
n=2.053
Explanation:
We will use Snell's Law defined as:
Where n values are indexes of refraction and values are the angles in each medium. For vacuum, the index of refraction in n=1. With this we have enough information to state:
Solving for yields:
Remember to use degrees for trigonometric functions instead of radians!
Answer:
Calcium bromide is the name for compounds with the chemical formula CaBr2(H2O)x.
Explanation:
Given that,
Initial speed of a car, u = 12 m/s
Aceleration, a = -1.6 m/s²
(a) The displacement of car after 6 seconds is :
(b) The displacement of the car after 9 seconds is :
Hence, this is the required solution.
Answer:
The final position of the ship after the given time period is 42 km West of B.
Explanation:
Given;
average velocity of the ship, v = 35 km/h
time taken for the ship to reach point D, t = 1.2 hours
The position of the ship after the given time period is calculated as follows;
x = v x t
x = (35 km/h) x 1.2 h = 42 km
x = 42 km West of B.
Therefore, the final position of the ship after the given time period is 42 km West of B.
