The water and solutes the first enters the nephron tubules undergo a process just before it exits the body as a urine. This process is called filtration. It operates when 20 percent of the solution volume is filtered in the renal corpuscle at a given time. It is reportedly stated that there are around 180 liters of this fluid being filtered by the kidney every day.
Answer: 1.96 m/s
Explanation:
Given
Mass of Professor
Velocity of professor
mass of chair
velocity of chair
Suppose after the collision, v is the common velocity
Conserving momentum
The sum of more than one velocity vector.
Or the sum of an initial velocity vector and an acceleration vector integrated over time.
More empty space in mass !!
speed of sound wave depends on elasticity of medium and density of medium
it is given by formula
now if wave travel through solid then its speed is maximum while if it travel from gas then its speed is minimum
so initially its speed is given as 4000 m/s and suddenly decrease to 1500 m/s
so here we can say that its medium will change from solid to liquid
<em>so sound will encounter with water </em>
