Answer:
C. is the data passed into a parameter.
Explanation:
From the list of given options, the answer that correctly answers the question is option C.
Literally, arguments are values passed into parameters in functions;
Take for instance, the following code snippet in python
<em>def testcode(num):</em>
<em> print(num * 2)</em>
<em>digit = 4</em>
<em>testcode(digit)</em>
In this example above;
The output is 8; and this is calculated by 4 * 2.
The parameter is <em>num</em><em> </em>and the argument is the <em>value</em> that will <em>be passed in num</em>; This value (argument) is 4
Answer:
56 J
Explanation:
Formula to find the kinetic energy is :
E_kEk = \frac{1}{2}21 × m × v²
Here ,
m ⇒ mass
v ⇒ velocity
Let us solve now
E_kEk = \frac{1}{2}21 × m × v²
= \frac{1}{2}21 × 7 kg × ( 4 ms⁻¹ )²
= \frac{1}{2}21 × 7 × 16
= \frac{1}{2}21 × 112
= 56 J
