Answer 1

Explanation:

Motion, in physics, change with time of the position or orientation of a body. Motion along a line or a curve is called translation. ... In both cases all points in the body have the same velocity (directed speed) and the same acceleration (time rate of change of velocity).

Answer 2

a. cout << "Hello world!";

Syntax in C++:

• In C++ programming language, "cout" prints the content which is written in the quotation marks
• It must be followed by an operator "<<"
• After the content is written in the quotation marks, a semi-colon must be used to denote the end of the particular line

Hence, the correct syntax to print the output or message in C++ is: cout << "Hello world!";
