Blasts are used for communicating different signals when vessels move.When a boat is leaving, a long blast, at intervals of not more than two minutes, is used for alerting other vessels, when a boat is sailing. When leaving the dock, only a single prolonged blast is used for indicating others, that you are leaving.
as you pump more gas into the balloon, the particles become more packed, in an attempt to gain more room, the particles push on the walls of the balloon, therefore, making it expand.
Answer:
R₂ = 3.31 m
Explanation:
For this exercise let's use trigonometry. Let's see the angle of the full moon
θ = x / R
Where x is the diameter of the moon and R the distance from the Earth to the Moon, the angle is measured in radians
x = 2 R
x = 2 1.74 10⁶
x = 3.48 10⁶ m
The distance is
R = 3.84 10⁸ m
Let's look for the supported angle
θ = 3.48 10⁶ / 3.84 10⁸
θ = 9.06 10⁻³ rad
For the coin to cover the moon it must have the same angle, let's look for the different
θ = x₂ / R₂
x₂ = 3 cm = 0.03 m
R₂ = x2 / θ
R₂ = 0.03 / 9.06 10⁻³
R₂ = 3.31 m
This distance in much greater than the arm length
