Consult Interactive Solution 7.10 for a review of problem-solving skills that are involved in this problem. A stream of water st

AlekseyPX

Explanation:

Initial speed of the incident water stream, u = 16 m/s

Final speed of the exiting water stream, v = -16 m/s

The mass of water per second that strikes the blade is 48.0 kg/s.

We need to find the magnitude of the average force exerted on the water by the blade. The force acting on an object is given by :

$F=\dfrac{m(v-u)}{t}$

Here, $\dfrac{m}{t}=48\ kg/s$

$F=48\times (-16-16)\ N\\\\F=-1536\ N\\\\|F|=1536\ N$

So, the magnitude of the average force exerted on the water by the blade is 1536 N.

A string of length 0.67 m and mass 2.0 g is held at both ends under tension. The string

ikadub [295]

Answer:

The value is $\lambda = 0.335 \ m$

Explanation:

From the question we are told that

The length of the string is $l = 0.67 \ m$

The mass is $m = 2.0 \ g = 0.002 \ kg$

The frequency produced at fourth harmonic vibration(i.e n =4 ) is $f = 700 \ Hz$

Generally the wavelength of the string is mathematically represented as

$\lambda = \frac{ 2L }{n }$

=> $\lambda = \frac{ 2 * 0.67 }{ 4 }$

=> $\lambda = 0.335 \ m$

What helps offset the ion diffusion through leak channels on neurons and helps return the membrane potential to its resting volt

Blizzard [7]

Explanation:

Resting potential is the static membrane potential of the dormant cells. It is opposite of the action potential or the graded membrane potential. Na+/K+ ATPase pumps helps offset the ion diffusion through leak channels on neurons and helps return the membrane potential to its resting voltage.
