NUCLEAR ENERGY1

Nuclear Energy Report Abstract This report is a study of the particles involved in nuclear energy. The atomic and nuclear energy levels of the finite, discrete energy values of alpha particles and gamma photons involved in the decay of unstable elements have been discussed with regard to nuclear energy. The

Simple Pendulum

Experiment on Simple Pendulum Pendulum Abstract. Objects in free fall accelerate towards the centre of the earth under the influence of the force of gravity. However, it is difficult to measure directly the acceleration due to the force of gravity. The gravitational force can be measured indirectly using a pendulum.

The benefits and disadvantages of a dosimetry program for all first responders within an organisation.

Dosimetry Program for Radioactive Agents 14 Dosimetry Program for Radioactive Agents Introduction Direct/indirect measurement and evaluation of exposure to kerma can be done using a dosimeter. The dosimeter may further be used in determining of the time derivatives and the exposure rate of ionizing radiation. The dosimetry system is made

X-ray absorption – applications in medicine

X-ray absorption application in medicine Introduction X-ray is ionizing radiation which exhibit particle-like and wave-like properties. It has very small wavelength that can penetrate far through matter, which makes it both dangerous and useful. Its ionizing radiation can damage the living tissue, thus there is need for safety precaution when

Electrical Circuit Experiment

To Determine the EMF (Electromotive Force) of a Cell and its Internal Resistance Cells are made to convert chemical energy into electrical energy. The EMF (electromotive force) of a dry cell (battery) refers to the energy converted into electrical energy when unit charge passes through a source. Electromotive force is

Simple pendulum

Determining gravity acceleration using a simple pendulum Department Introduction In this experiment the time of 10 oscillations of different lengths of a string attached to the suspended mass was measured, the angle in which the pendulum was left to swing was kept constant. For different lengths and fixed angle, evidence

Laboratory investigation

Introduction In nature many things are found to make vibration motions and the pendulum is a good case. A mass suspended at the end of a string is a good way of coming up with a simple pendulum. The to and fro motion was applied in controlling motion in cuckoo

Lab investigation

THE SIMPLE PENDULUM A simple pendulum consists of a mass suspended from a mass less string and left to swing with an initial angle. A pendulum moves with a periodic motion and the time it takes to complete one oscillation is called a period (Young at el., 2000). For small

Vibrations Analysis of Mechanical Systems

Executive summary The main aim of the report was to calculate several factors of a MDOF system. In this these regard potential energy, kinetic energy, differential equation of motion in matrix format and modal matrix has been determined. We further determined natural frequencies when k is 1N/m and mass is

COST EFFECTIVE AND EFFICIENCY ENERGY 1

Cost Effective and Efficiency Energy Technically, organic solar cells tend to reduce the cost of solar energy production based on its fabrication and characterization in real world situation. The proposal tends to focus on the cost effectiveness and efficiency of fabrication and characterization of organic solar cells through two different
