1. The location being in Ocean City will be favorable for all auditors conducting the audit. This will allow for ease of travel for all auditors involved. This will also lend to the knowledge the firm has of the business and all relevant operations pertaining to Oceanview Marine Company.
1.) According to Lao-tzu, what must the ruler provide the people with if they are to be happy?
15) A cart starts from rest and accelerates at 4.0 m/s2 for 5.0 s, then maintain that velocity for 10 s, and then decelerates at the rate of 2.0 m/s2 for 4.0 s. What is the final speed of the car?
2. For the flyer to have her center of gravity reach 25 feet, what does the initial velocity need to be?
| C. Occasional day by day, east to west motion of the planets relative to the stars
3. Explain whether, during a trip, a car’s instantaneous speed (movement of an object at a specific instant) can ever be greater than its average speed.
Nonmetallic properties tend to predominate for elements at the far right portion of the table.
Kinetic energy is the energy of an object in motion. By doubling the speed of the car you are increasing its kinetic energy 4 times higher. If the kinetic energy is being
Character 1: I think taxes should be raised. We could use those taxes to pay off our national debt.
= (6.626 x 10^-34 J∙s)(2.998 x 10^8 m/s)/(8.00 x 10^-7 m) E = 2.483 x 10^ -19
Children learn some of their behaviour from adults and other children that they spend their time with. The way that practitioners model and promote behaviour is an important part of creating a positive environment for children to learn, play and grow and where children will develop an understanding of how to behave.
Give an example of some incongruity that you have experienced that challenged you to recognize one of your assumptions.
1. In the first reaction, when acetylene gas was produced, another product produced in the reaction remained in the dissolved in the water: Ca(OH)2, also known as calcium hydroxide. Before lab was finished, the last step was to measure the pH of the previously neutral water in which the acetylene gas was used to be produced. This time, the red litmus paper turned blue and the blue litmus paper remained blue, signifying that the water was basic. The reason for this is because of the second product, calcium hydroxide. Calcium hydroxide made the water basic because of its hydroxide ions: when it dissolved in water, the calcium hydroxide went through a dissociation reaction, isolating the hydroxide ions in the water, thus making the water basic.
