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
Hope this helps you :-)
Let me know if you have any other questions :-)
I belive the correct answer would be binary code because computers see the coding as 00100001
Answer:
b. bc u can delete and add slides in ur presentation
Answer:
Explanation:
We could get the four options for this particular example, but we must know what happens with the variable number the value 1000.
In this case, we are going to assume four scenarios:
1) n = n - n this is equal to 0
2) n = (n - n) + n = 1000
3) n = n * 2 = 2000
4) n = n * 3 = 3000
These are simple examples, we could get these options in different ways.
<u>Answer</u>:
<em>By changing the decimal to a percentage
</em>
<u>Explanation:</u>
Since the requirement is to calculate the percentage of students about their preference in eating vegetables, we need to convert the given values to percentage only.
<em>
Option A: </em>By changing the addition sign to a multiplication sign. This is invalid because, there is no addition and multiplication involved in converting to percentage
<em>Option C:</em> By changing the percentage to a decimal. The given data is not available in percentage so conversion is impossible.
<em>Option D:</em> By changing the multiplication sign to a division sign Multiplication and division are not going to be performed here, since we need only percentage.
