Answer:
<h2>9.52 m/s²</h2>
Explanation:
The acceleration of an object given it's mass and the force acting on it can be found by using the formula
f is the force
m is the mass
From the question we have
We have the final answer as
<h3>9.52 m/s²</h3>
Hope this helps you
C is the best answer choice
Answer:
The wavelength can always be determined by measuring the distance between any two corresponding points on adjacent waves. In the case of a longitudinal wave, a wavelength measurement is made by measuring the distance from a compression to the next compression or from a rarefaction to the next rarefaction.

Answer:
The experiments are not shown, so I will answer in a general way.
By the first Newton's law, an object will only change it's velocity if there is a net force different than zero acting on the object.
Then in the experiments (depending on the experiment), you can see different things.
If an object is not moving and you apply a force in it, the object will move.
If an object is moving and you apply a force in the opposite direction of it's motion, the motion will: decrease the speed, stop at all, or move in the opposite direction. Depending on the force that you apply.
An excellent experiment (but hard to do) is dropping an object from a really high place.
The gravitational force will pull down the object and the object will start to increase it's velocity.
But there is the air resistance, that opposes to this motion and increases with the speed of the object.
Then there is a given speed such that the air resistance force will be equal to the gravitational force, then we have a balanced force (the net force is zero) which means that the object will keep falling at a constant velocity.
Answer: 2 days = 172,800 seconds
Explanation: 1 day is equal to 86,400 seconds so 2 days equal to 86,400 x 2 = 172,800 seconds.
