Answer:
In a two particle system, the center of mass lies on the center of the line joining the two particles.
To have a force of 3.8x10-8 the two chaarges must be 0.65m apart.
Explanation:
Average acceleration is the change in velocity over the change in time:
a = (v − v₀) / t
In the x direction:
aₓ = (6.11 cos (-54.2°) − 5.33 cos (37.9°)) / 2.00
aₓ = -0.316 m/s²
In the y direction:
aᵧ = (6.11 sin (-54.2°) − 5.33 sin (37.9°)) / 2.00
aᵧ = -4.11 m/s²
Answer:
1. at the top of the coaster.
2. at the bottom of the coaster.
3. when the car is moving
4. when the car is moving
Explanation:
there is the most amount if potential energy at the top, and the keast at the bottom.
-- Equations #2 and #6 are both the same equation,
and are both correct.
-- If you divide each side by 'wavelength', you get Equation #4,
which is also correct.
-- If you divide each side by 'frequency', you get Equation #3,
which is also correct.
With some work, you can rearrange this one and use it to calculate
frequency.
Summary:
-- Equations #2, #3, #4, and #6 are all correct statements,
and can be used to find frequency.
-- Equations #1 and #5 are incorrect statements.
