Aim To determine the critical angle of glass using a glass block Principle and Hypothesis The Snell’s Law of Refraction says that – At the boundary between any two given materials the ratio of the sine of the angle of incidence and the angle of refraction is constant for any particular wavelength. The refractive index is determined by the formula – R = Sin i Sin r Where i = angle of incidence of the ray of light r = angle of refraction of the ray of light The

NeedsSpace Case 9-4 NeedsSpace is leasing space to rent corporate offices from WeHaveIt. According to ASC 840‚ NeedsSpace has entered into an operating lease with a lease term of 10 years as defined by the Glossary in ASC 840 (paragraph 5(f) of Statement 13). The lease will be terminated at the end of the 10 year term and NeedsSpace will not be given the option to renew. The lease agreement specifies that the lessee may have to perform certain tasks at the cost of the lessee when the lease term

Does caffeine affect the heart rate of Daphnia? Introduction In this experiment I aim to find out if caffeine has an affect on heart rate. Instead of using human subject‚ whom may already have a high tolerance to caffeine or could have ingested caffeine that day making the tests unfair‚ I will use Daphnia‚ a crustacean. They have on contact with caffeine making it fair. It will be easier to observe as it has a translucent body‚ making it able to see the heart beating under a microscope. It will

-The three components of an attitude are cognition‚ affect‚ and behavior. T -The three components of an attitude are cognition‚ affect‚ and behavior. F -The intent to act in a certain way is the affective component of an attitude. F -The affective component of attitude is the emotional‚ or feeling‚ segment of an attitude. T -The cognitive component of an attitude describes an intention to behave in a certain way toward someone or something. F -According to Festinger‚ people seek consistency

receptor molecules on the host cell. Inside the viral envelope‚ the virus’s genetic material is surrounded by a protein coat (capsid). This genetic material contains at least 3 genes: gag – codes for core proteins‚ pol codes for reverse transcriptase and env codes for a viral envelope protein. These viral genes are encoded in single stranded RNA. The enzyme reverse transcriptase (derived from the pol gene) is present to reverse transcribe the RNA into DNA. Retroviruses have been split into 4 groups based
