Answer:
The magnitude of buoyancy force is equal to that of ball's weight.
Explanation:
Ball 1 is floating on water. Weight of ball 1 is Fg=m1g is acting vertically downward
Force of buoyancy FB = ρVdisg is acting vertically upward.
Net force acting on the ball is zero, FB=Fg
Answer
The magnitude of buoyancy force is equal to that of ball's weight.
Answer: left and applied force
Explanation:
Answer:
129.96
At a Gravitational acceleration of 32.17405 ( which is the normal rate for a freefall) you will geta velocity of 129.96 and the time of fall will be 4.039 seconds from 80 meters.
Why is the weight of a free falling body zero? It is not, an object in free fall will still have a weight, governed by the equation W = mg, where W is the object's weight, m is the object's mass, and g is acceleration due to gravity. Weight, however, has no effect on an objects free falling speed, two identically shaped objects weighing a different amount will hit the ground at the same time.
Hope this helps!! If so please mark brainliest and rate/heart to help my account if it did!!
The step of the scientific method with the information "This paper details my results on how dolphins use sonar to navigate." is: D. Report Results.
Science can be defined as a branch of intellectual and practical study that systematically observes a body of fact with respect to the structure and behavior of both living and non-living organisms in the natural world through experiments.
Some of the steps (activities or actions) that a scientist performs (carries out) while using a scientific method include the following:
- Analyze data and draw conclusions.
The results of an experiment provide the necessary data and information about the specimen which was used in the course of conducting an experiment.
Hence, a report result would convey these information to the user (reader) of scientific method proposed by a scientist.
In conclusion, a paper which details the results on how dolphins use sonar to navigate is considered a report of the results.

B. initiate an action potential.
Action potentials are initiated when a depolarization reaches a threshold potential. This threshold potential varies, but is normally around 55 or 50 millivolts above the resting potential of the cell, which implies that the input current of sodium ions exceeds the output current of potassium ions.
