Objectives: 1. Distinguish between system and surroundings. 2. Distinguish between heat energy and temperature. Name the SI units of temperature and thermal energy. 3. Calculate the heat content (thermal energy) of a substance using its specific heat‚ temperature and mass. 4. Solve calorimetry problems. 5. Name the energy associated with a change of state and calculate the energy required to change a given mass of substance from solid to liquid or liquid to gas. 6. Describe the changes in the microscopic

SPH3UC – Lesson 1 1. A) Amplitude is the distance between the equilibrium and the maximum displacement. In this wave‚ it would be from the equilibrium to the top of the crest or bottom of the trough. B) C) Speed: m/s Frequency: Hz D) Speed: because speed is constant and not affected by the change in frequency. Wavelength:0.4 Hz. 2. In transvers waves the motion of the particles is perpendicular to the direction of the energy. In longitudinal waves it they are parallel

1. Agency Problems of MNCs. a. Explain the agency problem of MNCs. ANSWER: The agency problem reflects a conflict of interests between decision-making managers and the owners of the MNC. Agency costs occur in an effort to assure that managers act in the best interest of the owners. b. Why might agency costs be larger for an MNC than for a purely domestic firm? ANSWER: The agency costs are normally larger for MNCs than purely domestic firms for the following reasons

How road safety has changed over the years Why Speed Limits Have Changed During the last 100 years speed limits have changed in the UK‚ now in residential areas speed limits are generally 20mph to 30mph and on main roads the speed limit is 40mph. On the motorways the speed limit is raised to 70 mph. The first speed limit was 1865; this speed limit was 2mph in built up areas such as cities‚ towns and villages. This was then raised to 20mph and large fines were put in place for speeding and

Title: Measuring the speed of sound. Research question: How to determine the speed of sound by using the relationship between the frequency of the signal generator‚ f and the length of air column in the tube‚ l . Variables: Manipulated | Frequency of the signal generator‚ f | Use different frequency of signal generator which are 1000Hz‚ 1400Hz‚ 1800Hz‚ 2000Hz‚ 2500Hz‚ 3000Hz and 3600Hz. | Responding | Length of air column in the tube‚ l (±0.5cm) | Measure the

In 1945‚ he was hired to cover the UN conference in San Francisco by the Chicago Herald-American. A school friend even said his temperament was better suited for writing (pg4). After his plane exploded over the English Chanel‚ JFK was devastated. Symbols changed from a blue star to gold so everyone will know there was a loss

Robert Frost’s poem “The Master Speed” of becoming better and going past what one thought they could. There is the common theme of sea and sky. No matter where someone is social or physically they can always do something more and become an even better person than they were before. Also that stopping can be a good thing; not everything in life needs to be so fast. Lastly always try to connect and bond with those around one as one can also help they be a better person too. Always strive to be the best

wondered why do we have speed limits? Or maybe you do and you’re the grandma driver that everyone is stuck behind in a no passing zone. Everyone has their own speeds so why shouldn’t you be able to go how fast or how slow you wanted to go. Should we strike down every sign that the government has put up to regulate the speed limit in the thousands of highways around the country? And should we trust the driving ability of each and every person to drive within a reasonably safe speed? People automatically
