How do liquids affect friction?

Physics

Although liquids offer resistance to objects moving through them, they also smooth surfaces and reduce friction. Liquids tend to get thinner (less viscous) as they are heated. ... The rubbing produces friction and the result is heat.

A 790N person runs up a flight of 40 stairs (.25m for each step) in 20 seconds, and then down 10 steps in 5 seconds. How much to
Romashka [77]

A person runs up 40 stairs and then come down 10 steps

So total stairs upwards is given as

N = 40 - 10 = 30

now here we will have total height reached

H = N\times h

H = 30 \times 0.25 = 7.5 m

Now total energy used or mechanical work done is

W = mgH

W = 790 \times 7.5 = 5925 J

Now the mechanical power is given as

P = \frac{W}{t}

P = \frac{5925}{20+ 5} = 237 W

Lena [83]

Answer:

4. Personnel policies and programs

Explanation:

The Health care organizations that apply for Magnet status must demonstrate new ways of doing things and innovations in professional practice.

Personnel policies and programs is one of the forces of magnetism that impacts the structural empowerment of the organization.

The Personnel policies of an organization should provide an innovative environment in which the staff are developed and empowered. Empirical quality outcomes are reviewed by assessing the quality of care. New knowledge, innovations, and improvements are reviewed by assessing the quality improvement of the health care organization. Interdisciplinary relationships are assessed to review exemplary professional practice.

Svetradugi [14.3K]

Answer:

The formula for the separation between the plates, d = V/E and d = 1.02 mm

Explanation:

Here is the complete question

The electric field strength between the plates of a simple air Capacitor is equal to the voltage across the plates divided by the distance between them When a voltage of 112. V is put across the plates of such a capacitor an electric field strength of 1.1 kV/cm is measured. Write an equation that will let you calculate the distance d between the plates. Your equation should contain only symbols. Be sure you define each symbol

Solution

The electric field strength between the plates of a simple air capacitor is given by E = V/d where V = electric potential between the plates and d = separation between the plates.

Making d the separation between the plates subject of the formula, we have

d = V/E

Since V = 112 V and E = 1.1 kV/cm = 1100 V/cm

Substituting the values of the variables into the equation, we have

d = V/E

d = 112 V/1100 V/cm

d = 0.102 cm

d = 1.02 mm

So, the formula for the separation between the plates, d = V/E and d = 1.02 mm.
