Answer:
1.435 x 10^-4 cm^3/s
Explanation:
coefficient of viscosity, η = 0.028 poise
Radius, R = 0.008 cm
length, l = 2 cm
Pressure, P = 5000 dyne/cm^2
The Poiseuille's formula is given below
Where, V is the rate of flow, that means volume flowing per second
V = 1.435 x 10^-4 cm^3/s
Thus, the rate of flow is 1.435 x 10^-4 cm^3/s.

Answer:
The terminal speed of this object is 12.6 m/s
Explanation:
It is given that,
Mass of the object, m = 80 kg
The magnitude of drag force is,
The terminal speed of an object is attained when the gravitational force is balanced by the gravitational force.
On solving the above quadratic equation, we get two values of v as :
v = 12.58 m/s
v = -15.58 m/s (not possible)
So, the terminal speed of this object is 12.6 m/s. Hence, this is the required solution.
Answer:
Time use of cellphone times 3 hours before sleep.
Explanation:
It is scientifically proven that cell-phone use before bed can disturb your sleep. The blue light can cause your brain to release chemicals that associate with staying awake or even waking up. So measure the hours or minutes you use your phone 3 hours before you go to sleep.
Answer:
As waves get closer to a beach they decrease in height.
Explanation:
As a wave crest approaches the shoreline, it is usual that one end of the line is closer to the shoreline than the other. The implication of this is that the energy in a wave is also spread over quite a larger area,this in turn reduces the height of the waves. In other words, refraction often makes waves smaller.
Waves are caused by wind. Wave height in the open ocean is determined by three factors. The greater the wind speed the larger the waves. The greater the duration of the wind (or storm) the larger the waves. The greater the fetch (area over which the wind is blowing - size of storm) the larger the waves.
