What are 700N?
What is the SI Unit for electric current?
What is Ampere?
DNA is found in this part of the cell.
What is nucleus?
This quantity is tangent to the circle of a uniform circular motion in the direction of the motion.
What is tangential velocity?
This kinematic quantity is constant in a free fall near the surface of the Earth.
What is acceleration due to gravity?
Vertical Component of a force acting at an angle of θ can be determined by multiplying the magnitude of the force with this.
What is sinθ?
Electromagnetic waves are commonly called this.
Continents on are continuously moving on Earth because of the movement of ....
What are tectonic plates?
This type of orbit follows the rotation of the Earth.
What are geosynchronous orbits?
When one ball is dropped and another similar ball is thrown horizontally from the same height, the time difference between each ball hitting the ground is.....
What is 0 second?
When a rollercoaster rolls down a hill, it converts potential energy into this form of energy.
What is kinetic energy?
This scientist was jailed in Italy by the Catholic Church when he discovered the moons of Jupiter.
Who is Galileo?
You land on exoplanet X and weigh 100N on the planet. You now move to exoplanet Y that has four times the mass of exoplanet X but twice as far from their parent star. Your weight on exoplanet Y will be...
What is 100N?
This part of a velocity vs time graph represents displacement.
What is the area under the curve?
Normal force on an object is perpendicular to....
What is the surface in contact with the object?
This law relates potential difference as the product of current and resistance.
What is Ohm's Law?
This particle travels through cell membranes to create a voltage difference and open voltage gated channels for other ions to pass through.
What are electrons?
Exoplanets are often discovered by detecting the wobbling of the parent star due to the gravity exerted on the star by the exoplanet. The wobble is due to the star and planet orbiting each other around this point.
What is their Center of Mass?
A B777-300ER can accelerate at 1.6 meters per second squared from rest. It needs to reach a takeoff decision speed of 73 meters per second with 1000 meters remaining in the runway as per FAA rules. The pilot determined this is the minimum runway length necessary for her aircraft to takeoff in whole meters.
What are 2666 meters?
A flying airplane does a maneuver called banking when it makes a turn in flight to minimize this force.
What is Centripetal Force?
This force binds neutrons and protons together in the nucleus of an atom.
What is Strong Nuclear Force?
Alice and Bob just got married right before she embarks on a space ship for 5 years traveling at 80% the speed of light. When she returns, Bob had passed away 10 years ago on Earth. Einstein explains this phenomenon with General Relativity as......
What is time dilation?
