lara31 [8.8K]

Answer:

(iii) A has pH greater than 7 and B has pH less than 7

Explanation:

Phenolphthalein is a common indicator in acid base titrations. It turns pink in basic conditions and turns colorless in acidic conditions. Thus on addition of solution A it becomes pink so A should be basic having pH more than 7. On addition of B , it turn out to be colorless means that B is an acidic solution having pH less than 7.

Sound waves are transverse mechanical waves. <br><br> True<br> False
allochka39001 [22]

False

Explanation:

Sound waves are longitudinal mechanical waves.

Mechanical waves are waves that requires a medium to propagate them.

  • A transverse wave is a wave that is propagated perpendicularly to its source.
  • An example is electromagnetic radiation.
  • A longitudinal wave is a wave that is directed parallel to their source.
  • Sound wave is a longitudinal wave.
  • It has series of rarefaction and compression along its travel path.
  • Rarefaction are areas of sparse particles.
  • Compression are areas with dense particles.

What is 10 times as many as 1 hundred is blank hundred or blank thousand ?
Rama09 [41]

10 times as many as 1 hundred is 10 hundred or 1 thousand.

This is the question of simple multiplications related to a place value system.

The given equation in unit form can be rewritten as:

10 × 1 × 100 = (X × 100) or (Y × 1000)

Arranging in two parts, we get,

10 × 1 × 100 = X × 100           ........(1)

10 × 1 × 100 = Y × 1000         ........(2)

Now, calculating the value of X and Y,

From equation (1), we get,

10 × 1 × 100 = X×100

or, 1000 = X × 100

or, X = 10

Hence, 10 times as many as 1 hundred is 10 hundred.

Similarly, from equation (2). we get,

10 × 1 × 100 = Y × 1000

or, 1000 = Y × 1000

or, Y = 1

Hence, 10 times as many as 1 hundred is 1 thousand.

Therefore, 10 times as many as 1 hundred is 10 hundred or 1 thousand.
