Answer:

The value is  H  =  0.036 \ kg/m^3

Explanation:

From the question we are told that

   The saturation density of air is \rho =  0.04 \ kg/m^3

   The temperature for this saturation density to occur  T_s  =  96^o F

    The relative humidity at this temperature is  R_h  =  90\%  =  0.90

Generally the relative humidity is mathematically represented as

      R_H  = \frac{H}{\rho}

Here H represents humidity

=> 0.90 =  \frac{H}{0.04}

=>  H  =  0.90 * 0.04

=>  H  =  0.036 \ kg/m^3

If you can see the blinking insertion point in a field, you are in ________.
Sonja [21]
You would be in an editing mode when you can see a blinking insertion point on a field. In addition, in any word processing software, it would basically signify that you can already type on the document. Another name for the insertion point would be the I-beam as displayed on the screen.

As light shines from air to water (n = 1.33) at an incident angle of 45.0 degrees what is the angle of refraction
erma4kov [3.2K]
Using Snell's law
we get
sin(I)/sin(r) = U2/U1
• where U2 represent the water's refractive index and U1 represent air's refractive index
thus
sin45°sin(r) = 1.33/1
1/√2*1.33 = sin(r)
1/1.88 = sin(r)
0.531 = sin(r)
thus the refractive angle is 32°

Use the kinematic equation,

Vf^2 = Vi^2 + 2aX

31.5^2 = 11.6^2 + 2(5.22)(x)

Solve for x

I lift a 20kg ball up 2.5 meters off the ground on Earth.
Umnica [9.8K]

Answer: How much gravitational potential energy does the ball have at this point? At h = 20.4 m the gravitational potential energy of the ball reaches maximum.  

How much work did I do lifting up the ball?  As you are lifting the object you are doing work on the object. The work W done on an object by a constant force is defined as W = F·d. It is equal to the magnitude of the force, multiplied by the distance the object moves in the direction of the force.

A large room in a house holds 947 kg of dry air at 33.2°C. A woman opens a window briefly and a cool breeze brings in an additio
BartSMP [9]

Answer:

31.96362 °C

Explanation:

m_1 = Mass of air in the room = 947 kg

m_2 = Mass of air entering the room = 62.4 kg

T_1 = Temperature in the room = 33.2°C

T_2 = Temperature air entering the room = 13.2°C

T = Equilibrium temperature

c = Specific heat of air = 1006 J/kg °C

In the case of thermal equilibrium we have the relation

m_1c(T_1-T)=m_2c(T-T_2)\\\Rightarrow T=\frac{m_2T_2+m_1T_1}{m_1+m_2}\\\Rightarrow T=\frac{62.4(13.2+273.15)+947(33.2+273.15)}{947+62.4}\\\Rightarrow T=305.11362\ K=305.11362-273.15=31.96362^{\circ}C

The temperature of thermal equilibrium is 31.96362 °C
