Combustion Engine Exhaust----Cars, trucks, jet airplanes and other combustion engine vehicles cause air pollution. The exhaust from these contains carbon monoxide, nitrous oxide and gaseous oxide. This type of air pollution creates smog
Fredd must use the trait theory for the online personality tests because it is based on distinctive features.
<h3>What is the trait theory?</h3>
The trait theory is a model that states people have certain basic personality traits which are distinctive features.
The trait theory is always based on the strength of these basic human trait characteristics.
The trait theory is based on three types of features capable of being used to describe personality, which include stability, consistency and individual differences.

Answer:
frequency
Explanation:
speed of light = <u>constan</u>t = wavelength * frequency
changing WL or F will change the other
The change in energy after the collision is <u>0.5</u>
<u />
<h3>What is change in energy?</h3>
This refers to the difference in the energy where energy is the capacity to do work. There different forms of energy they include mechanical energy, solar energy, electrical energy and so on.
The energy described in the problem is mechanical energy and it is of two types kinetic energy and potential energy
<h3>solving for the change in energy as a result of the collision</h3>
where mass of particle mp = 4 kg
mass of object mb = 6 kg
force constant of spring k = 100 N/m
amplitude A = 2 m
kinetic energy = 1/2 mv^2
initial velocity u = Aω
ω = sqrt ( 100/ 4 )
u = 2 sqrt ( 100/ 4 )
u = 10m/s
final velocity v = 5 m/s
change in energy
= - 0.5 * ( 4 + 4 ) * 5^2 + 0.5 * 4 * 10^2 ) / 0.5 * 4 * 10^2
= 0.5

The pressure drop in pascal is 3.824*10^4 Pascals.
To find the answer, we need to know about the Poiseuille's formula.
<h3>
How to find the pressure drop in pascal?</h3>
- We have the Poiseuille's formula,
where, Q is the rate of flow, P is the pressure drop, r is the radius of the pipe, 
is the coefficient of viscosity (0.95Pas-s for Glycerin) and l being the length of the tube.
- Thus, the pressure drop will be,
Thus, we can conclude that, the pressure drop in pascal is 3.824*10^4 Pascals.
