START QUIZ!
What is the best estimate for the radius of a hydrogen atom?
Remember 10-10 m and convert to cm
A motor raises a 10 kg mass at a constant speed of 5 ms-1. If the input power is1 kW what is the efficiency of the system?
power out = Fv = mgv = 500 W
Eff = Pout/Pin = 500/1000
3 forces act on a point object causing it to accelerate upwards. Which free-body diagram represents this situation?
Resultant force is upwards.
The graph represents the force applied to an object of mass 20,000 kg.
impulse = Area = 4000 x 20/2 = 40,000
Change in v = impulse / mass
A ball of mass m is thrown with initial velocity v at angle q to the horizontal as shown.
What is the kinetic energy at F?
)2
)2
horizontal component of velocity is constant
A ball starting from rest rolls down a slope with constant acceleration. It is photographed 3 times, at times t= 0 s, t = 1 s and t =2 s.
What Is the acceleration of the ball?
use s = 1/2 at2
a = 2s/t2 = 2 x 4 / 22
The two graphs below represent the collision of two balls of equal mass with a wall.
If the scales on each graph are the same how is the impulse and force different?
Impulse ----- Force
change in velocity is the same but time is different.
The graph shows the rise of temperature as a metal cube of mass m is heated.
If the power supplied is P and the gradient of the line k, what is the heat capacity of the metal cube?
Q = CΔT
P/Δt = CΔT/Δt
Two gas flasks of equal volume are connected by a narrow tube. Flask P is kept at a temperature of 200 K and flask Q at 600 K.
What is the ratio
\({number \ of \ moles\ in \ P\over number \ of \ moles\ in \ Q}\)
Same pressure and volume so nT = constant
n is proportional to 1/T
nP/nQ = TQ/TP
Sound travels from A to B by two paths, one direct 680 m through cold air near the ground and the other 20m longer as it refracts through layers of warm air. Each sound arrives at the same time.
If the speed of sound in cold air is 340 ms-1 what is the speed in warm air?
time is the same = d/c = 680/340 = 700/c
What is true about the velocity of a pendulum bob executing simple harmonic motion?
at equilibrium acceleration = zero but velocity = max
What are the changes to speed and wavelength when sound passes from air into water?
Speed ---- Wavelength
wave speeds up so peaks are more spread
he 1st harmonic of the guitar string shown has frequency f.
What frequency note would be played if a node is made to appear at point P?
wavelength will be1/4 of 1st harmonic
The circuit represents two resistors connected to a cell.
What changes would occur in the ammeter and voltmeter readings if the switch was closed.
Ammeter ---- Voltmeter
short circuiting R reduces total R so current increases and pd increases
A hydrogen atom enters a region of magnetic field, in the direction shown.
Which of the arrows below best represents the path of the particle?
hydrogen atom has no charge so not deflected by B field.
A cell of EMF 12 V is connected to 3 resistors as shown.
What is the potential difference across X?
Total R = 6Ω
I = 12/6 = 2A
V = IR = 2 x 3
What is the work done on the mass?
force is perpendicular to direction of motion.
The activity of a radioactive source decays from 110 Bq to 35 Bq in 1 minute. After 1 hour the detector still registers a constant count rate of 10 Bq. What is the half-life of the source?
10 Bq is the background count so subtract from counts
100 to 25 is 2 half lives.
A radioactive element with proton number Z decays into one with proton number Z-1 . Which series of emissions could result in this?
alpha results in Z - 2
beta results in Z + 1
Which conservation law is violated by the following interaction?
p+ + e- → n0
electron has lepton number 1
The power output from a wind turbine is 10 kW with a wind speed of 4 ms-1. What will the power output be for a wind speed of 12 ms-1?
P is proportional to v3
V is x3 so P is x27
The Sankey diagram represents the energy flow in a power station.
The efficiency of the power station is approximately
top arrow is about 1/3 of the energy in
What part of a nuclear power station reduces the rate of the chain reaction?
control rods absorb neutrons
A mass attached to 2 springs oscillates between points A and B.
At which position is the resultant force on the mass zero?
balanced at the equilibrium position
The diagram represents light of wavelength λ diffracted by a slit of width a.
What change would increase y?
ay/D = λ
y = λD/a
