Answer:
Part a)
Part b)
Part c)
v = 100 m/s
Part d)
since wave is moving in +x direction
so here the sign must be negative
so complete wave equation is
Explanation:
As we know that the wave equation is given as
here we know that
= maximum displacement of the particle
Part a)
maximum displacement = amplitude
so here we know that
Part b)
k =
here we know that length of the string is 3 m
it consist of 3 loops
so we will have
so we have
Part c)
v = wave speed
v = 100 m/s
Part d)
since wave is moving in +x direction
so here the sign must be negative
so complete wave equation is
Answer:
Explanation:
Let say the ball is projected at an angle with horizontal
So here two components of the velocity of the ball is given as
now the displacement in x direction is given as
in y direction it is given as
now from above two equations
Answer:
This is Newton’s third law (forces due to friction). There would be 15N being pushed back at Jane.
Explanation:
Newton’s third law states that for every action there is an equal and opposite reaction. So if Jane pushed with a force of 15N, 15N would be pushed back at her. Hope this helps! :)
