Aim What is the effect of differing pendulum length on its period? Hypothesis If the length of the pendulum is decreased‚ the period will decrease. Variables Independent: The length of the pendulum (cm) Dependent: The period of the pendulum (s) Controlled: The weight of the swinging mass The angle for maximum displacement Materials: Pendulum (can be as simple as a mass tied to string attached to a piece of cardboard) Retort stand and clamp Stopwatch Ruler Protractor Masking tape

IA Factors affecting the time period of a pendulum. Research question: How does the length of a pendulum affect its time period? The independent variable is the length. The dependent variable is the time. Controlled variable is the mass of the pendulum bob. Formula for 1 period of oscillation of a pendulum of a certain length is T=2π √lg Where l is length and g is gravity (9.81 ms-2) T2= 4π2 lg T2= 4π2g l Hypothesis: The longer the length of the pendulum is‚ the longer

9 Popular Ways to Determine Your Marketing Budget 1. Percentage of revenues This is by far the most talked about method of determining your budget. This method works by taking a fixed percentage of your revenues (that’s every penny your company brings in) and allocating that amount for marketing.

What is a static budget? A static budget is a budget that does not change as volume changes. If a company’s annual master budget is a static budget‚ the budget for sales commissions expense will be one amount such as $200‚000 for the year. In other words‚ in a static budget the budgeted amount for sales commissions expense will remain at $200‚000 even if the actual sales during the year are $3 million‚ $4 million or $5 million. In contrast to a company’s static master budget‚ the company’s sales

usually less than 0.25mm in length and covered with minute hair-like projections called cilia. They are characterized by their cilia which are used in locomotion and during feeding. Paramecia feed on bacteria. Paramecia have 2 nuclei‚ 1 macronucleus and 1 micronucleus. Some have up to 80 micronuclei! The organism cannot survive without macronucleus and cannot reproduce without micronucleus. I used the 4x on the Parmecium caudatum to measure 11 cells they varied in length from 145.44-199.98um‚

Criteria for Curricular Design‚ Implementation and Evaluation* Criterion 1- Curricular Structure: Is the curriculum sufficiently complete? What are the current education elements? What is missing? Criterion 2 - Curricular Sequence: Is the sequential logic of the curriculum optimal? For example‚ are curricular elements optimally sequenced for learning clinical method and related topic areas? This involves the idea of learner readiness. Criterion 3 - Curricular Element Proportionality: Does

Looking back on situations in one’s life‚ one cannot help but to reflect on the changes that could have been made. One is always in regret and dreams an imaginary scenario about what could have happened and what should have happened. Would it not be better to look into the past as appoint of information to adjust the present so in order not to repeat the same “mistakes”? (Unless addiction or other mental health issues cover elsewhere). Or look into the future and plan how to get to your point B
