**Answer:**

Spills out 10cm³ of wather.

**Explanation:**

The ball being submerged halfway in the full glass of water will spill a volume of water equal to the volume of the ball that is being submerged, because the entire volume of the submerged ball was previously occupied by water and is not compressed should move out of the glass.This volume will be 10cm³ since the total of the ball is 20cm³ and it is submerged halfway.

**Answer:**

was the her position ahead from her window when she caught the object.

**Explanation:**

Given:

- speed of walking of Henrietta,

- height of projection of projectile,

- Horizontal distance between the window and Henrietta when the projectile was launched:

- Since the projectile was thrown at the time when she had passed below the window 5 seconds ago.

Since the projectile was thrown horizontally therefore the vertical component of velocity is zero.

<u>Now the time taken for the object to reach to Henrietta ignoring the height where she catches:</u>

is the time taken by the projectile to reach Henrietta.

<u>Now the distance further walked by Henrietta in the above time from the point where she was when the projectile was launched:</u>

<u>Now the total horizontal distance from the window to Henrietta when the projectile reached her:</u>

** was the her position ahead from her window when she caught the object.**

<u>Now the initial horizontal velocity of launch of the projectile:</u>

There are no terminals on the wire where the bird is sitting. If the bird wants terminals,

he must move to one end of the wire, but he will find only one terminal there. The

other terminal is at the other end of the wire, conceivably hundreds of miles away.

No species of bird extant in the modern world can accomplish such a span.

**Answer:**

v = 172 km/h

**Explanation:**

For the first 12 hours, it traveled at an average speed of 185 km/h. Let d₁ is distance. So,

For the next 13 hours, it traveled at an average speed of 160 km/h. Let d₂ is the distance. So,

**Average speed = total distance/time taken**

So,

**So, the average speed of the whole journey is 172 km/h.**
