well this is all I got. hope it helps. its for higher btw!
No energy resources, no fission/fusion, no pressure, no atomic structure, no national grid, no uses of radiation, no circuit diagrams
Ø 0.17 A
Ø 2.7 W
Ø 0.5 m
Ø 60 kg mans weight
Ø 1.16 x 10^-3 g / 0.016kg
Ø 7.5 A
Ø 300 seconds
Ø 2.5m
Ø 0.19 kg
Ø 0.05 kg density
Ø 2 x 10^-6 / 0.000002 coloumbs change of spark
Ø 120 ohms
Ø Diesel vs electric/ battery cars
Battery is cheaper and more efficient.
Diesel reduces demand from national grid and quicker than chargig up a battery.
Ø Thermal Insulation practical
Ø power
Ø Alpha radiation
what contamination is, linked it to how Alpha is highly ionising and that it mutates cells causing cancerous cells
Ø 6 mark
adding different layers of insulation of newspaper onto the beaker. also talk about using a lid on top to minimalize heat loss and start with 0 numbers of insulators.
Ø Best thermal conductivity
copper
Ø how do u go from steam to a Bunsen burner
thermal energy from burner = converted to kinetic in water particle = more collision = increase temperature = evaporates
Ø Muscular power difference between men and women (graph Q)
o Talk about how the peak of muscular power in female happens at a younger age than in males
o volunteers who were under 10 years
o the females had a higher muscular power
o mention the male and female highest muscular power
o a general pattern in graph
Ø equate the specific heat capacity equation and the latent heat. Mass of ice?
total energy in terms of m when m= mass and then dividing 5848 by the number in front of m(the energy was equal to 365500 x mass)
ANSWER: 0.016 kg
Ø what does mass have to do with power output?
Mass of different people are different so they travel at faster speed
Ø Density question
0.0502
Ø 12.5 for a temperature
Ø 234 mass no. 90 atomic no.
Ø Specific heat Capacity
0.01933 / 0.01933....... and rounded to 0.02
Ø latent heat of water and dividing the energy by the amount of time, which was 300 seconds (5 mins) to get the power in watts.
300 secs
Ø 50HZ
Ø How high did the man jump? the height one using GPE? Zipline?
0.5m / 2.5m
Ø 5 mark Working out resistance of defibrillator
Convert 4ms to 0.004 seco ds
divide 120,000 by 1000 because time was in milli seconds
