When preparing for a rocket launch, the mission control center uses the phrase "T minus" before liftoff. ...T minus 3, T minus 2, T minus 1, ... After the rocket has launched, "T plus" is used while the rocket is in flight. ...T plus 1, T plus 2, T plus 3, ... When does the rocket launch? What does "T" represent?

Answers

The rocket launches when the countdown reaches "T minus 0." "T" represents the time remaining until a specific event.

What does "T" symbolize in rocket launch countdowns?

In the context of rocket launches, "T" represents time. The countdown begins with "T minus" indicating the time remaining until liftoff. As the countdown progresses, the value of "T" decreases, counting down to zero, which marks the exact moment of launch.

Once the rocket is airborne, the countdown transitions to "T plus," denoting the time elapsed since liftoff. This standardized countdown terminology allows mission control to communicate crucial timing information precisely and efficiently during various phases of the rocket's journey.

What does trajectory mean?

Answers

Trajectory means the path that something follows.

It's almost always used to describe things that are dropped, thrown, or shot,
like the trajectory of baseballs, golf balls, and canon balls, or other things moving
under the influence of gravity, like comets, asteroids, and planets.  But it doesn't
have to be the path of something sailing overhead from one place to another.
You'll also hear about a person's 'trajectory through life'.
A trajectory is the path that a moving object follows through space as a function of time. The object might be a projectile or a satellite

What is the Compact Muon Solenoid used to study?

Answers

The Compact Muon Solenoid (CMS) experiment  is a particle physic detector which is used to investigate and search for the Higgs Boson, and particles that is related to dark matter. Other goals of this experiment is to for evidence such as supersymmetry and extra dimensions. It is built on a LHC or Large Hadron Collider at CERN in Switzerland and France. 

Answer:

It is designed to accurately detect and study Muons.

Explanation:

Compact Muon Solenoid (CMS) is part of Large Hadron Collider (LHC) of CERN and has a use as a general purpose detector. It weighs around 14000 Tonne and built around a giant solenoid magnet. That's how it got its name: Compact Muon Solenoid (CMS). It generates 4 Tesla magnetic field  that is around 100000 times the Earth's magnetic field. A yoke made up of steel is used to confine this intense field. This strong magnetic field is used to bend the path of particles.

In LHC, protons are accelerated to a very high speed in clockwise and anticlockwise direction and then collided with each other. On collision particles will be sprayed out in all directions. CMS takes the photograph and collects data during these collisions. Its main purpose is to detect Muons which are around 200 times heavier than electrons.

A quantity that has magnitude only is a _____.
scalar
diagonal
vector

Answers

A quantity that has magnitude only is a scalar. In Physics, a quantity with only magnitude is called a scalar. Scalar quantities include distance, speed, mass, temperature, and energy. They are distinguished from vectors which have both magnitude and direction.

A scalar is a fundamental concept in mathematics and physics, representing a single quantity with magnitude but no direction. Scalars are characterized solely by their numerical value, such as speed or temperature. Unlike vectors, which have both magnitude and direction, scalars are concerned with the "how much" rather than the "where" or "in which direction." Scalars are used in various fields, from physics to mathematics and engineering, simplifying the description of quantities that don't involve direction, making calculations and analysis more straightforward.

A quantity that has magnitude only is referred to as a scalar. In Physics, quantities are typically classified into two types: scalars and vectors. A scalar quantity is defined by its magnitude alone, with no direction associated with it. Examples of scalar quantities include distance, speed, mass, temperature, and energy. On the contrary, a vector has both magnitude and direction. Hence, the correct answer to your question is scalar.
