A cloud in space that is composed of dust and gas is call a nebula. The word "nebula" is derived from the Latin word for "cloud," and nebulae in space are indeed large interstellar clouds made up of dust, hydrogen, helium and plasma.
Answer:
PAPER CLIPS ON NOSE OF A PAPER AIRPLANE
Purpose: To determine if the number of paperclips on the nose of a paper airplane affects the velocity and speed, measured in meters per seconds.
Make a Hypothesis Based on the Learning Thus Far: If the number of paperclips on the nose of a paper airplane increases, then the speed will _increase______ (increase, decrease, stay the same) in a __linear_______ (linear, exponential, logarithmic) mathematical relationship, and the velocity will (increase, decrease, stay the same) in a __exponential____ (linear, exponential, logarithmic) mathematical relationship. (Fill in the appropriate words for your hypothesis.)
Pictures: Insert at least 3 pictures of yourself conducting the experiment into this lab report. At least 2 pictures must show your face as you conduct the investigation. You may need to ask someone to help take these photos.
Explanation:
A 50w motor can do 500w in 5 seconds
Answer:
The answer is "
"
Explanation:
For point a:
Energy balance equation:
From the above equation:
because the rate of air entering the tank that is 
constant.
Since the tank was initially empty and the inlet is constant hence,
Interpolate the enthalpy between 
. The surrounding air
temperature:
Substituting the value from ideal gas:
Follow the ideal gas table.
The 
and between temperature 
Interpolate
Substitute values from the table.
For point b:
Consider the ideal gas equation. therefore, p is pressure, V is the volume, m is mass of gas. 
(M is the molar mass of the gas that is 
and R is gas constant), and T is the temperature.
For point c:
Entropy is given by the following formula:
