Starches are more than chains of sugar granules strung together. In the case of corn starch, it is actually millions of these molecules packed into very discrete granules, which cannot be seen by the naked eye. Putting corn starch into cold water, nothing happens because cold water does not dissolve these granules. Putting it into hot water (like cooking gravy) however, these granules dissolve and create bonds between the water and the starch.
Answer:
Since there is attraction force between two charges so the other charge must be - 3C
Explanation:
As we know that the force between two charges is given by formula
here we know that
also we know that
r = 8 cm
now we have
so we have
The grandfather clock will now run slow (Option A).
<h3>What is Time Period of an oscillation?</h3>
- The time period of an oscillation refers to the time taken by an object to complete one oscillation.
- It is the inverse of frequency of oscillation; denoted by "T".
Now,
, where L is the length and g is the gravitational constant, is the formula for a pendulum's period. - The period will increase as one climbs a very tall mountain because g will slightly decrease.
- Due to this and the previous issue, the clock runs slowly and it seems that one second is longer than it actually is.
Hence, the grandfather clock will now run slow (Option A).

Answer:
1.0 x 10-14.
Explanation:
We then replace the term on the right side of this equation with a constant known as the water dissociation equilibrium constant, Kw. In pure water, at 25C, the [H3O+] and [OH-] ion concentrations are 1.0 x 10-7 M. The value of Kw at 25C is therefore
<h2>Answer: Sedimentary rocks
</h2>
Sedimentary rocks are formed from sediments and deposits of particles of various types, forms and sizes that are transported by air, wind or water, and then subjected to chemical processes to become rocks.
These types of rocks are usually found in the form of layers or strata in places where sediment accumulates due to the erosion of other materials, for example on the banks of rivers, in valleys, lakes (and any other type of body of water).
