Answer:
The object moves 0.0833 m downwards.
The object moves 8.33 cm downwards.
Explanation:
Weight of object = W = 6 × 9.8 = 58.8 N
Mass of liquid displaced = 3.45 kg
Meaning that buoyant force = Fb = 3.45 × 9.8 = 33.81 N
drag force on the object from the liquid is negligible.
Net force acting on the object = ma
Force balance on the object gives
Net force = W - Fb + D
W = 58.8 N
Fb = 33.81 N
D = 0
Net force = 58.8 - 33.81 = 24.99 N
ma = 24.99
6a = 24.99
a = (24.99/6) = 4.165 m/s²
Now, using one of the equations of motion
u = 0 m/s
a = 4.165 m/s²
y = ?
t = 0.200 s
y = ut + ½at²
y = 0 + (0.5 × 4.165 × 0.2²)
y = 0.0833 m
Since the Weight of the body is more than the buoyant force exerted by the liquid on the object, the object moves downwards.
Hope this Helps!!!

As we know that speed of sound is
frequency of sound is
now we know that frequency of sound and speed of sound is related to each other by the following formula
<em>so wavelength of sound is 25 cm or 0.25 m</em>
