Over the past few decades man has always embarked on different space exploration by traveling to the moon. A typical Journey to the moon from Earth will take about 3 days in recent times.
- It takes about 3 days for a spacecraft to reach the Moon. During that time a spacecraft travels at least 240,000 miles
- In the year 1969 the first man (Neil Armstrong ) landed on the moon, the journey took him 8 days, 3 hours, 18 minutes, 35 seconds, on 16 July.

To model time-variant data, one must create a new entity in an m:n relationship with the original entity, is a False statement.
- Like the majority of software engineering initiatives, the ER process begins with gathering user requirements. What information must be retained, what questions must be answered, and what business rules must be implemented (For instance, if the manager column in the DEPARTMENT table is the only column, we have simply committed to having one manager for each department.)
- The end result of the E-R modeling procedure is an E-R diagram that can be roughly mechanically transformed into a set of tables. Tables will represent both entities and relationships; entity tables frequently have a single primary key, but the primary key for relationship tables nearly invariably involves numerous characteristics.

Answer:
Unit of work done is Joule. Therefore, the dimension formula of work is represented as [M1 L2 T-2].Explanation:
Mass of caboose 1000 kg
mass of caboose plus mass of middle car = 3000 kg
a = 5
F = ma
3000 * 5 = 15.000 N

energy moves through the sun in two main way, Radiation and Convection.
Explanation:
as the energy moves outward from the sun's core, 1st enters rhe radiation zone. the radiation zone is a region of highly compressed gas. here the energy is transferred by the absorption and irradiation of electromagnetic waves
