Topic A
DEF: This vector quantity represents the change in position of an object.
What is displacement?
DEF: This law describes the force between two point charges.
What is Coulomb's Law?
This is the process by which a large nucleus splits into smaller nuclei, releasing energy.
What is nuclear fission?
A heat engine takes in 1000 J of heat from a hot reservoir and rejects 600 J to a cold reservoir. This is the efficiency of the engine.
What is 40%?
This is her first name, spelt out.
What is Briahna?
COM: A car travels 50 meters in 5 seconds. This is its average speed.
What is 10 m s^-1?
COM: This happens to the electrostatic force between two charges if the distance between them is doubled.
What is 1/4 the original force?
The fundamental particle responsible for carrying electromagnetic force.
What is a photon?
The amount of energy required to change the state of 1 kg of a substance at constant temperature.
What is specific latent heat?
Mrs. Attebery has taught these subjects.
What is biology, IB Physics, chemistry, physical science, AVID, and integrated middle school science?
DEF: This term describes the rate at which an object rotates or revolves, measured in radians per second.
What is angular velocity?
DEF: This law states that the induced EMF in a circuit is proportional to the rate of change of magnetic flux linkage.
What is Faraday's Law of Induction?
The half-life of a radioactive sample is 10 days. This is how many days 80% of the original sample will have decayed.
What is approximately 23.2 days?
This phenomenon occurs when waves bend as they pass through an opening or around an obstacle.
What is diffraction?
The number of years Mrs. Attebery has been teaching at IHS.
What is 8 years?
COM: A 2 kg object moving at 5 m/s collides head-on with a 3 kg object at rest. If they stick together, this is their common velocity after the collision.
What is 2 m s^-1?
A uniform magnetic field of 0.8 T is directed into the page. A square loop of wire with side length 0.2 m is placed in the field. If the loop is pulled out of the field in 0.1 seconds, this is the induced EMF.
What is 0.32 V?
This effect explains the emission of electrons from a metal surface when light of a sufficient frequency shines on it.
What is the photoelectric effect?
A uniform rod of mass 2.0 kg and length 0.5 m is pivoted at its center. A 10 N force is applied perpendicularly to one end. This is the initial angular acceleration of the rod. (Moment of inertia of a rod about its center is (1/12)*M*L^2)
What is 60 rad s^-2?
This is the first name of her student teacher.
What is Brittney?
COM: A spaceship travels at 0.8c relative to Earth. If a clock on Earth measures 10 years, this is the time that would have passed on the spaceship.
What is 6 years?
When a charged particle moves perpendicular to a uniform magnetic field, its path will be this shape.
What is a circle?
The approximate binding energy, in MeV, of an alpha particle, given that its mass defect is 0.030377 u. Note that 1 u = 931.5 MeV c^-2.
What is 28.3 MeV?
An ambulance approaches a stationary observer at 30 m/s, emitting a siren sound with a frequency of 800 Hz. This is the frequency heard by the observer. (Speed of sound in air = 340 m/s)
What is approximately 877 Hz?
This is the year Mrs. Attebery graduated from high school.
What is 1997?
