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

This tells the Mission Control What will be happening
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. 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.
