Answer:
v = 9 m/s
Explanation:
It is given that,
Initial speed of the sailboat, u = 3 m/s
Acceleration of the sailboat, 
Initial speed of the motorboat, u = 0
Acceleration of the motorboat, 
Time elapsed, t = 3 s
To find,
The velocity of the sailboat
Solve,
Let v is the velocity of the sailboat after 3 seconds. By using the equation of kinematics, it can be calculated.
v = 9 m/s
Therefore, the velocity of the sailboat is 9 m/s.
Answer:
L = 2.8 cm
Explanation:
Period T = 4 / 12 = 1/3 s
T = 2π√(L/g)
L = (T/2π)²g
L = ((1/3)/2π)²9.8 = 0.02758... ≈ 2.8 cm
Answer:
Light passes through the gas
Light passes through the pure water
Light passes through some solids
Explanation:
In gasses, there are many spaces between the molecules. These spaces allow light to pass through them without any interruption.
In pure water, there are some spaces between particles. these particles allow some light rays to pass theough, some to move through the common boundary and reflec5 some of them.
in solids, some allow light to pass through as they are transparent or translucent
