1. B. Hemo is on a machine, peritoneal is in the abdomen
2. B. Nothing is as good as having your own kidney, and not everyone is a good candidate for all types of dialysis.
3. Also B. Peritoneal dialysis is done over a longer period of time, up to 24 hours. Hemodialysis is done in a few hours. Your kidney works 24/7.

artcher [175]

Answer:

Less than Mercury's

Explanation:

According to third Kepler's law, the square of the planet's orbital period is proportional to the cube of the average orbital radius of the planet's orbit. The constant of proportionality depends only on the mass of the star, recall that 51 Peg has the same mass as the Sun. Since the orbital period of this planet is less than Mercury's, its average orbital radius is less than Mercury's.

What experiment should I make using Gravitational Force? <br><br>PLEASE HELP ME :)
Bogdan [553]

You could try the "Spinning Bucket" or the "Center Of Gravity" experiment. There are plenty more that you could research! Hope this helped :)

A dentist using a dental drill brings it from rest to maximum operating speed of 391,000 rpm in 2.8 s. Assume that the drill acc
krek1111 [17]

Answer:

a

    \alpha  =  2327.7 \ rev/s^2

b

   \theta = 9124.5 \ rev

Explanation:

From the question we are told that

    The maximum  angular   speed is  w_{max} =  391000 \ rpm  =  \frac{2 \pi  *  391000}{60} =  40950.73 \ rad/s

     The  time  taken is  t =  2.8 \ s

     The  minimum angular speed is  w_{min}= 0 \ rad/s this is because it started from rest

     

Apply the first equation of motion to solve for acceleration we have that

       w_{max} =  w_{mini} +   \alpha  *  t

=>     \alpha  = \frac{ w_{max}}{t}

substituting values

       \alpha  = \frac{40950.73}{2.8}

       \alpha  =  14625 .3 \  rad/s^2

converting to rev/s^2

  We have

           \alpha  =  14625 .3 *  0.159155 \ rev/s^2

           \alpha  =  2327.7 \ rev/s^2

According to the first equation of motion the angular displacement is  mathematically represented as

       \theta  =  w_{min} * t  + \frac{1}{2} *  \alpha  *  t^2

substituting values

      \theta  =  0  * 2.8  + 0.5  *  14625.3  *  2.8^2

      \theta  = 57331.2 \  radian

converting to revolutions  

        revolution = 57331.2 *  0.159155

        \theta = 9124.5 \ rev
