Answer:

Fire detecting Scanner.

Explanation:

Fire detecting Scanner is a system which has the ability to scan the area and tells the changes occurs in the fire inside the earth crust. This scanner collect all information about the area on the basis of which we can take steps to avoid the damage caused by the fire. With the help of this scanner we can tell that which part is safe and which part of the area is dangerous for people.

The price of a book is thrice that of an exercise book. of a student spend #9600 on book and #8000 on exercise book, he has 56 i
poizon [28]

Answer:

a) price of an exercise book = #200

b) #400

Explanation:

Let x represent the price of the book

Let y represent the price of the exercise book

- According to this question, the price of the book is thrice that of an exercise book i.e. x = 3y

- Also, the question states that if a student spend #9600 on book and #8000 on exercise book, he has 56 items altogether. This means that to get how many books and exercise books he bought, we divide the price of book and exercise book he bought by the price of each book (x) and exercise book (y) respectively. Mathematically, this means:

- Student bought 9600/x books

- Student bought 8000/y exercise books

So, 9600/x books + 8000/y exercise books = 56 item

9600/x + 8000/y = 56

Since x = 3y

We can say;

9600/3y + 8000/y = 56

Find the L.C.M of 3y and y = 3y and solve using fraction method (see attachment).

9600 + 24000/3y = 56

33600/3y = 56

Cross multiply

33600 = 56 × 3y

33600 = 168y

Divide both sides by 168

33600/168 = 168y/168

200 = y

y = 200

Since, x = 3y

x = 3 × 200

x = 600

Therefore, the price of book (x) and exercise book (y) are #600 and #200 respectively.

b) The difference between the price of a book and an exercise book i.e. x - y

= #600 - #200

= #400

4. In gel electrophoresis, are the dna fragments attracted to, or repelled from the negative pole of the electric field?
Rzqust [24]

In the gel electrophoresis, the DNA fragments are repelled from the negative pole of the electric field.

<h3>What do you mean by Gel electrophoresis?</h3>

Gel electrophoresis may be defined as a technique that separates DNA, RNA, and proteins on the basis of their molecular weight.

As we all know, DNA fragments are negatively charged in nature, and hence they always move towards the positive pole of the electric field.

Therefore, in the gel electrophoresis, the DNA fragments are repelled from the negative pole of the electric field.

To learn more about Gel electrophoresis, refer to the link:
