Answer:
option D
Explanation:
given,
increase the intensity by factor of 9
I₁ = I₀
I₂ = 9 I₀
now,
A₂ = 3 A₁
hence, amplitude increase with the factor of 3
so, the correct answer is option D

Answer:
C
Explanation:
Gravity is the main reason that make our planets to pull each other
Answer:
Also 3s.
Explanation:
Each component is independent in two dimensional motion. This means that <em>how much time does something take to reach the ground when dropped is independent from any horizontal velocity</em>. If at one run a drop lasts 3s, at another run with twice the (horizontal) velocity and same height will also last 3s, no matter what.
