force and motion I problem 1 The figure below is an overhead view of a 12 kg tire that is to be pulled by three ropes. One force (Fl‚ with magnitude 50 N) is indicated. Orient the other two forces F2 and F3 so that the magnitude of the resulting acceleration of the tire is least‚ and find that magnitude if (a) F2 = 30N‚ F3= 20 N; (b) F2= 30 N‚ F3 = 10 N; and (c) F2 = F3 = 30 N. problem 2 A weight-conscious penguin with a mass of 15.0 kg rests on a bathroom scale (see figure below).

SPECIFIC GRAVITY BY DENSITY BOTTLE AIM OF THE EXPERIMENT:- To determine the Specific Gravity of soil a particle passing through 4.75 mm IS sieve using Density bottle. APPARATUS REQUIRED:- i. Density bottle of 100 mm capacity. ii. Desiccators. iii. Balance with sensitivity of 0.01 gm. THEORY:- Specific Gravity is the ratio of the mass in air of given volume of dry soil solids to the mass of equal volume of distilled water at 4 o C. Or ratio of unit weight of soil

sigmoid or peak phenomenon? Please provide supporting details. 6.What are the limitations of the population dynamics lab? Is the lab activity a realistic representation of an arctic marine ecosystem? Note: Please provide detailed support for your opinion. Birth‚ death‚ migration‚ community interactions‚ and abiotic factors can influence the size of a population. Changes to ecosystems‚ due to season‚ climate‚ and successions‚ can also impact population growth and decline. The effects of all of these components

Definition Gravity Survey - Measurements of the gravitational field at a series of different locations over an area of interest. The objective in exploration work is to associate variations with differences in the distribution of densities and hence rock types. Occasionally the whole gravitational field is measured or derivatives of the gravitational field‚ but usually the difference between the gravity field at two points is measured Geophysical interpretations from gravity surveys are based

LAB: Substrate Concentration Affecting the Rate of Enzyme Activity: Through the Experiment of Beef Liver Puree and Hydrogen Peroxide Research Question Does different amount of substrate affect the rate of enzyme activities? Purpose To examine how different types of concentration (Hydrogen Peroxide) affect the rate of enzyme activity. Hypothesis We believe that if there is more substrate concentrated‚ then there will be an increase in the rate of enzyme activity. This is because

In this lab we tested the effect of temperature has on the rate of enzyme activity. The way we figured this out was by taking four different temperatures and testing the difference absorbance levels they produced every 20 seconds for about 2 minutes straight using a spectrophotometer. The important part of this experiment was the temperature the enzyme concentration was made at. What we got from the experiment was at lower temperature we got very low numbers for the absorbance‚ which gave us a lower
