Answer:
Buoyant force which is equal in magnitude to the fish's weight
Explanation:
A fish floating motionless below the surface of a lake, is an equilibrium position with the water.
Hence, upward force must be equal to downward force.
The downward force is due to fish's weight while the buoyant force is the upward force due to force of the water.
A wooden log is displaced to a distance of 20m in 10 seconds by applying 500N effort . Calculate the workdone and power...
Solution,
displacement = 20 m
time = 10 sec
force = 500 N
work done = ?
power = ?
Now ,
work done = f × s
= 500 N × 20 m
= 10000 j
Now ,

Answer:
<em>Increase in wave frequency only</em>
Let x be the speed of the slower car and that x + 20 be the speed of the faster car. The time it takes for the object to travel a certain distance is the quotient when distance is divided by the speed.
t = d / S
Substituting the given and equating their times,
t = 225 / (x + 20) = 165 / x
The value of x is equal to 55. Therefore, the value of t is equal to 3 hours.
