**Answer :**

The time is

(B) is correct option.

**Explanation :**

**Given that,**

Diameter = 100000 light year

Velocity = 0.99 c

**We need to calculate the time**

**Using formula of time**

Put the value into the formula

**Hence, The time is **

**Answer:**

**a) 12.56 rad per minute**

**b)62.8 inches per minute**

**Explanation:**

Given:

**Radius** of the blades, R=5 inches

**Frequency **of the blades, f=2 revolutions per minute

a)

Let be the angular velocity of the blade which is given by

b)

**Let v be the linear speed of the tip of the blade which is given by**

**Hence we have calculated the angular velocity and linear speed.**

C because the the smallest thing then the other ones because it never said what kind of size of it

Answer: To boost its acceleration because the Earth rotates Eastwards and to ensure that any crash will occur on an ocean and huge loss in life and properties will be averted.

Explanation: A space shuttle turns to the east as soon as possible,this is to ensure that the space shuttle acceleration is supported by Earth rotation which is also Eastwards.

Another reason for ensuring that the space shuttle turns Eastwards as soon as possible is to prevent a huge loss of life if there is any chance of crash by the space shuttle.When the space shuttle turns Eastwards it will ensure that any crashing will possibly be on the an ocean hence a huge loss of life an property in populated areas will be averted or reduced.
