A car travels in a circular path with radius 20 m at a constant speed of 10 m/s. What is the magnitude of its acceleration?
5 m/s/s
Explain why a transformer only works with alternating current.
Changing current induces a changing magnetic field, which creates emf; DC does not
Why does Young’s double slit experiment provide evidence for the wave model of light?
Shows interference pattern, a wave property
Explain how spectral lines provide information about the composition of distant stars.
Each element has unique spectral lines
Which module would you study to learn about the formation of elements in stars?
From the Universe to the Atom
Derive the expression for orbital velocity for a satellite in terms of the gravitational constant, mass of the planet, and orbital radius.
v=sqrt(GM/r)
Using Faraday’s Law, calculate the emf induced in a coil of 10 turns when the magnetic flux changes by 0.2 Wb in 0.01 s.
emf=−NΔΦΔt=−10×0.20.01=−200 Vemf=−NΔtΔΦ=−10×0.010.2=−200 V
Explain how the results of the Michelson-Morley experiment challenged the concept of the luminiferous aether.
No difference in light speed was found—suggests no aether
Describe how observations of cosmic microwave background radiation support the current model of the atom.
Shows early universe conditions, supports atomic formation after Big Bang
Explain why the wave-particle duality of light is important in modern physics.
It explains phenomena like the photoelectric effect and interference, leading to quantum theory
