This is a pile of sediment debris deposited by a moving glacier, and comes in terminal, lateral, and medial types.
What is a Moraine?
What kind of RNA links codons to amino acids within a ribosome?
What is tRNA?
Within a molecule of methamphetamine, the majority of atoms are of what element that naturally forms a diatomic gas?
What is Hydrogen?
I have a lever. I apply a force to a point some distance along the moment arm. How would I determine the magnitude of the torque I am applying to the lever?
What is multiplying the magnitude of the force by the distance along the omoment arm (Force x distance)?
If a function passes both the horizontal and vertical line test, then what kind of function is it?
(hint:either injective, bijective, or surjective)
What is a Bijective Function?
This is the shape of the cloud pattern with a vortex inside it that forms around Saturn’s northern pole, first discovered through the Voyager missions and rediscovered through the Cassini-Huygens mission
What is a Hexagon?
This organ has diastolic and cystolic phases, and can undergo a life-threatening condition called arrhythmia. Formerly thought to be the seat of human life and consciousness.
What is the Heart?
This liquid can expand to about 1700 times its original volume when vaporized. It also has powerful adhesive and cohesive properties.
This is an approximation in orbital mechanics that reduces any n-body problem into a system of 2-body problems using Keplerian orbits. Each orbit is a conic section with a set apoapsis, periapsis, and eccentricity, and can take parabolic shapes or hyperbolic shapes as well.
Fun Fact: It’s used to approximate orbits in Kerbal Space Program!
What is the Patched conics approximation?
Note: the patched conics approximation is incapable of modeling the behavior of lagrange points
To the nearest whole number, what is the slant height of a right circular cone of radius 7 and height 6?
What is 9?
What gas is primarily trapped on the ocean floor as a hydrate, and is released during the depressurization of cores drilled out from the ocean floor?
What is Methane (CH4)?
Of what taxonomical class are sharks and rays members?
What is Chondrichthyes?
What named pericyclic reaction is classically the reaction of a di-ene with a dienophile in a single, concerted step?
What is the Diels-Alder reaction?
This is a phenomenon that often occurs when a photon directly collides with matter, and is the dominant mode of interaction between high-frequency photons and matter.
It is also the primary culprit of Hawking radiation, where one produced particle is sucked into a black hole while the other is free to escape.
What is Pair production?
Rounded to the nearest integer, what is the geometric mean of 6, 12, and 26?
What is 12?
Astronomers sometimes notice that spectral lines can be broadened due to the presence of strong magnetic fields. What is the name for this effect?
Zeeman Effect
In the lac operon in E. coli, CAP acts as an activator protein. What second messenger must bind to CAP to activate transcription of DNA?
What is Cyclic Amp (cAMP)?
I have an ideal cylindrical hollow pipe, and I am pumping an ideal fluid through it. The flow of the fluid is laminar, and obeys Poiseuille’s law. If the velocity of fluid at the center of the pipe is 5 meters per second, what is the velocity of fluid at the walls of the pipe?
What is 0 m/s (stationary)?
Physics crossover!
Consider a relativistic spaceship moving at 0.6 times the speed of light (c) relative to earth. If this spaceship fires a particle that moves at 0.6*c relative to the spaceship in the same direction as the spaceship, what is the ratio of the partivle’s velocity to the speed of light as seen by an observer on Earth?
What is 15/17?
This tensor physical quantity generalizes the stress tensor of Newtonian mechanics, and its components are the source of the gravitational field in the Einstein field equations of general relativity.
What is the Stress-energy tensor?
Alt: stress-energy-momentum tensor, energy-momentum tensor
