Which letter shows the ball when it has the maximum kinetic energy

Computers and Technology
1 answer:
DedPeter [7]3 years ago
5 0

Answer:

D.

Explanation:

Kinetic energy can be defined as an energy possessed by an object or body due to its motion.

Mathematically, kinetic energy is given by the formula;

K.E = \frac{1}{2}MV^{2}

Where;

  • K.E represents kinetic energy measured in Joules.
  • M represents mass measured in kilograms.
  • V represents velocity measured in metres per seconds square.

Generally, when the final velocity at which a physical object moves is equal to zero (0), then it possess maximum kinetic energy.

Hence, the letter which shows the ball when it has the maximum kinetic energy in the graph attached is D.

(03.05 LC) Match the term with its description. (4 points) Column A 1. Acid : Acid 2. Alkaline : Alkaline 3. pH : pH 4. Ion : Io
Nady [450]

Answer:

Follows are the matching to this question:

Explanation:

Column  A            Column B

     1                           c

     2                          d

     3                          b

     4                          a

Description of the matching:

  • In 1(Acid) the correct choice is (c) because the acid (HCl) dissociates to both the H+ ion and the Cl- ion as a solution.  
  • In 2(Alkaline ) the correct choice is (d) because alkaline NaOH is a solution that differentiates between the ions ( OH-) and Na+.  
  • In 3(pH ) the correct choice is (b) because for an A compound of less than 7 is an acid and an alkaline pH compound of more than 7. For neutral compounds, a pH of 7 is applicable.
  • In 4(Ion) the correct choice is (a) because Na+ ion is loaded positive, and Cl-ion is loaded negatively.

Which of the following is not a valid variable name? 2 myInt 2. return 3. myInteger 4. total3
Reptile [31]

Answer:

Correct answer is option (2) that is "return".

Explanation:

In any programming language, a variable name can be made up of letters (lower and upper case) and digits. we can also use "_" underscore character for declaring the variables but we cannot use any special character like “$”.We cannot use digits in the beginning of variables name. And we also cannot use reserved keywords of the language like "new","return","while" etc. There should not be space between the variable names. Options 1, 3 and 4 are not violating any of these properties. But in option (2), "return" is a reserved keyword. That is why it is not a valid variable name.

Some example of valid variables name:

foo

BAZ

Bar

_foo42

foo_bar

Some example of invalid variables name:

$foo    ($ not allowed)

while   ( keywords )

2foo    (started with digit)

my foo  (spaces )
