- Physics Unit 1
- Usefulness of electrical appliances
- energy released depends of power and time
- no. of units (kwH) used = power (kW) x time (hours) cost = no. of units x price per unit
- Methods to generate electricity
- releases substances, waste materials, noise pollution, destruction of habitat
- Carbon capture - preventing carbon dioxide releasing in the atmosphere
- oil or gas fields
- Energy and efficiency
- energy cannot be created nor destroyed
- thickness of sankey = amount ofenergy
- Heat transfer
- Evaporation - high temp, low density, large surface area, airflow is great
- Condensation- low temp, high density, airflow is less
- U-Value is how effective a mat. is at being an insulator (how fast)
- Specific heat capacity - how much energy is required to change 1kg of a substance by 1 degree
- Waves
- Red shift - further, faster, longer wavelength
- CMBR - low frequency radition
- initially hot, high frequency, expands, cools, low frequency
- plane mirror - virtual, upright, laterally inverted
- Transverse - oscillation perpendicular to direction
- Longitudinal - oscillation parallel to direction
- Usefulness of electrical appliances
