Answer:
A. Gravitational force are proportional to the masses of the two objects.
The pressure within the can would increase upon heating and decrease upon cooling.
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
Part 1)
here we know that supply took 10 s to reach the ground
so here we will have
Part 2)
Here all the supply covered horizontal distance of 650 m in 10 s interval of time
so here we can say
