To oscillate is to move or swing back and forth at a regular speed.
An oscillating telephone pole is similar to an oscillating tuning fork because they are both swinging back and forth, but the tuning forth is most likely oscillating at a much higher speed.
From information given, there are two forces in action, the vertical and the horizontal. We first need to calculate separately work done by these two forces, then determine the efficiency.
Work = Force × distance
work(a) → 600N × 2m = 1,200 Nm
work(b) → 300N × 5m = 1,500 Nm
Efficiency = work(a) / work (b) × 100
Efficiency = 1200 / 1500 × 100
Efficiency = 0.8 × 100
Efficiency = 80%
Therefore the efficiency of the ramp is 80%
Answer:
<h2>7.5 N</h2>
Explanation:
The force acting on an object given it's mass and acceleration can be found by using the formula
force = mass × acceleration
From the question
mass = 2.5 kg
acceleration = 3.0 m/s²
We have
force = 2.5 × 3.0 = 7.5
We have the final answer as
<h3>7.5 N</h3>
Hope this helps you
Work equals force × displacement (distance between initial point and end point is displacement)
if u follow this it becomes
work = 50 × 2 which is equal to 100
comment if u have more questions
Frequency can be defined as the ratio between the speed of the wave and its wavelength, that is
At the same time, the frequency is the inverse of the Period so
If we join the two expressions we will have to
Replacing we have that
Therefore the period of the wave is
