Step-by-step explanation:
I don't know what you need to do. Have you studied the quiz or more specific have you studied the questions that you have problems with? Also make sure you have enough sleep and have healthy food. You don't have to do read what I say(type) but it could help you.
Initially, Ball A of 10 kg will have velocity x, while Ball B of 30 kg has velocity -10 m/s.
After collision, Ball A will have a velocity of -30 m/s, while Ball B will have velocity 10 m/s. We assume their masses do not change.
(10 kg)(x m/s) + (30 kg)(-10 m/s) = (10 kg)(-30 m/s) + (30 kg)(10 m/s)
10x - 300 = -300 + 300
x = 30 m/s (to the right)
Answer:
Option D -Parallelogram and rhombus is the correct answer.
Step-by-step explanation:
<u>Option A -Square.</u>
In square all sides are equal and all angles are equal and each angle is equal to 90°
<u>Option B - Parallelogram </u>
In Parallelogram opposites sides are equal and parallel. there is no right angles.
<u>Option C -Rectangle</u>
In rectangle opposites sides are equal and parallel. All angles are equal to 90°
<u>Option D -Parallelogram and rhombus</u>
In Parallelogram opposites sides are equal and parallel. there is no right angles.
In rhombus all sides are equal and parallel. there is no right angles.
Therefore correct answer is option D
