ANS:A - Only assumption I is implicit

Explanation: The statement defines 'Success' as 'bouncing up'. This means that success can be achieved by striving hard to touch the top, without being harassed by any of the hurdles which come in the way. So, I is implicit. The fact in II cannot be assumed from the given statement.

ANS:C - a variable acceleration

The given answer is correct as velocity increases by an equal amount by an equal interval of time.

That means if the current velocity is 10m/s then after 5sec it will be 15m/s and after the next 5sec, it will be 20m/s and so on. As the velocity is changing with time so acceleration is variable. If the velocity of a body increases by equal amounts in equal intervals of time, then the body is said to be moving with uniform acceleration.

This is because acceleration is defined as the rate of change of velocity with time. If the velocity is changing by equal amounts in equal intervals of time, then the acceleration is constant, and the body is said to be moving with uniform acceleration.

Suppose velocity is increasing in such way that at t=1 distance is 2m and t=2 distance is 4m and similarly, t=3 distance is 6m then velocity V1=2m/s and V2=4m/s and V3 = 6m.

Now for Acceleration =change in velocity/change in time.
a1 = 2-0/1-0 = 2m^2/s.
a2 = 4-2/2-1 = 2m^2/s
a3 = 6-4/3-1 = 2m^2/s

ANS:C - < 1

The length/diameter ratio of a ball mill typically varies, but it is generally greater than 1.

Explanation:

• Ball Mill: A ball mill is a cylindrical drum (or tube) with a rotating shaft containing steel balls that grind materials as the drum rotates.
• Length/Diameter Ratio: This ratio refers to the ratio of the length of the cylinder (drum) to its diameter. It is an important factor in determining the efficiency and capacity of the ball mill.
• Typical Values:
  • Ball mills commonly have length/diameter ratios ranging from around 1 to 1.5. Ratios higher than 1 indicate that the cylinder is longer than it is in diameter.
  • A higher length/diameter ratio can improve the efficiency of grinding by providing a longer path for the material to be ground and increasing the residence time of the material in the mill.
• Effect on Performance: The length/diameter ratio affects the grinding efficiency, residence time of the material in the mill, and the eventual product size distribution.
