Answer:
The correct answer is - Characteristics.
Explanation:
On Earth, there are many organisms that shared similar characteristics with other organisms in various ways. These similarities of the characteristics could result from similar habitat, common ancestor, similar function, genetics, and many other reasons.
The example of such shared characteristics are different kinds of birds that have wings and lay eggs, while mammals give birth to babies and many other traits and characteristics. On the basis of the traits and characteristics organisms shared they are grouped and classified.
Answer:

Explanation:
Consider the motion of the ball attached to string.
In triangle ABD

height gained by the ball is given as

= mass of the ball attached to string = 110 g
= speed of the ball attached to string just after collision
Using conservation of energy
Potential energy gained = Kinetic energy lost

Consider the collision between the two balls
= mass of the ball fired = 26 g
= initial velocity of ball fired before collision = ?
= final velocity of ball fired after collision = ?
using conservation of momentum

Using conservation of kinetic energy

{Answer}
A- (10kg sphere and 30m)
