What is the extension of the spring?
12cm
10cm
12mm
10mm
Why is adjusting the ruler important?
To reduce the error in measuring the extension of the spring
To stop it falling over
Because it looks better
Because otherwise Hooke's Law will be broken
What range of weights did the student use?
5N
0 - 6N
1 - 6N
0N
What can you conclude from Figure 4 about the deformation of the spring?
The spring is broken
It's not a spring, it's a slinky
The spring has been inelastically deformed
The spring has gone past it's limit of proportionality
What name is given to this effect?
Bed-Shift
Dead Shift
Red Shift
Bread Shift
What relationship between the speed of a galaxy and the distance is suggested by Hubble’s results?
the further away from the Earth, the more people getting 9's in their GCSEs
the further away from the Earth, the slower a galaxy is moving
the further away from the Earth, the faster a galaxy is moving
the further away from the Earth, the faster the sun is moving
Give one strength of this model in representing the idea of an expanding Universe.
the persons face represents the big bang
as the balloon expands the dots get further apart, representing the galaxies moving apart
the balloon will eventually pop, showing a supernova
dots are only on the surface of the balloon, galaxies are throughout the universe
Give one weakness of this model in representing the idea of an expanding Universe.
there is a limit to how far the balloon can expand
as the balloon expands the dots get further apart, representing the galaxies moving apart
dots are only on the surface of the balloon, galaxies are throughout the universe
balloons are expensive
In what way do the observations made by Hubble support both Theory 1 and Theory 2?
both theories suggest that the earth is getting slower
both theories suggest that red shift is moving the galaxies
both theories suggest that the Universe is expanding
both theories suggest that the Universe is slowing down
Most scientists now believe that Theory 2 is correct. Suggest what is likely to have caused scientists to start thinking Theory 1 is wrong
the discovery of red-shift
scientists were stuck in their ways
new evidence / observations that cannot be explained by Theory 1
both theories were proved wrong
The student measured the magnification produced by the lens by measuring the image height in centimetres. Explain why the image height in centimetres was the same as the magnification.
magnification = image height ÷ object height
they used a concave lens
dividing by an object height of 1 cm gives the same (numerical) value
the magnification was wrong
magnification = object height ÷ image height
Suggest one change that could be made so that accurate magnification values could be obtained for distances greater than 60 cm.
use a taller object
use a bigger magnifying glass
use a (travelling) microscope
use a computer
attach a scale to the screen and use a magnifying glass
Give a second way that the student could have determined the magnification of the object. Justify your answer with a calculation.
by dividing the distance between the lens and the image by the distance between the lens and the object
e.g. 100÷25 = 4
by using a larger microscope to make the image smaller
e.g. 30÷90 = 0.33
using a convex lens instead
Describe how you could show that a magnetic field has been produced around the wire.
move a (magnetic/plotting) compass around the wire the changing direction of the compass needle shows a magnetic field has been produced
use an electromagnet to see how it interacts with the wire
something to do with fleming?
throw it at a metal surface
Why is iron a suitable material for the core of a transformer?
It is a metal.
It will not get hot.
It is easily magnetised.
It is an electrical conductor.
How can you tell that transformer J is a step-down transformer?
p.d. across the primary coil is smaller
p.d. across the secondary coil is smaller
p.d. across the secondary coil is bigger
p.d. across the primary coil is bigger
the ‘theory’ is the basis of many other ideas
the scientists were wrong
nothing can travel faster than the speed of light
the experiments were not carried out correctly
to sell their results to corporations
to assess the importance of their findings
to assess the reproducibility of the data
to allow peer review of data
because they were asked to by CERN
5.34 x 10-5s
4.1 x 102s
2.19 x 1011s
2.43 x 10–3 s
60 × 10-3 s
60 × 10-6 s
60 × 10-9 s
60 × 10-12 s
What name is given to the type of error made by the scientists?
systematic error
timing error
measurement error
counting error
Suggest what the scientists should do to calculate an accurate value for the speed of a neutrino.
repeat the experiments
minus 60 nanoseconds to each time recorded and recalculate
add on 60 nanoseconds to each time recorded and recalculate
use previous experimental data
What is the difference between distance and displacement?
distance is a vector and displacement is a scalar
distance is a scalar and displacement is a vector
distance has a direction, displacement does not
displacement has direction, but distance has a magnitude
the distance travelled by a driver at a constant speed
the distance travelled before the driver reacts
the distance travelled whilst stopping a car
the distance travelled under the braking force
the reaction time will increase
the reaction time will decrease
increasing the thinking distance
increasing the braking distance
the car will be affected
13 m/s
16 m/s
18 m/s
24 m/s
so number of collisions with a surface decreases
air molecules colliding with a surface create pressure
there are more air particles at a higher altitude
at increasing altitude distance between molecules decreases
at increasing altitude distance between molecules increases
The pressure inside the cabin of an aircraft is kept at 70 kPa. The aircraft window has an area of 810 cm2 . Use data from Figure 17 to calculate the resultant force acting on an aircraft window when the aircraft is flying at an altitude of 12 km.
4000N
2400N
4050N
3670N
force from air pressure acting from outside to inside bigger than force acting outwards
force from air pressure acting from inside to outside bigger than force acting inwards
so window falls out
so keeps the window in position
in a longitudinal wave the oscillations/vibrations are parallel to the direction of energy transfer.
in a transverse wave the oscillations/vibrations are parallel to the direction of energy transfer.
they both travel at the speed of light
in a transverse wave the oscillations/vibrations are perpendicular to the direction of energy transfer
Describe one piece of evidence that shows when a sound wave travels through the air it is the wave and not the air itself that travels.
I don't know :(
eg. a vibrating drum skin does not move the air away to make a vacuum
eg. when you talk you can hear your own voice
eg. in space you cant hear sound
What is the name of the effect that causes the wire X to move downwards?
magnet effect
fleming's left hand rule
motor effect
fleming's right hand rule
Suggest one change you could make to the apparatus in Figure 20 that would increase the size of the force that wire X experiences.
reduce the magnet strength
change the batteries
move the wire closer
increase the strength of the magnet
