<u><em>Answer:</em></u>
B. 285 km/5 min
<u><em>Explanation:</em></u>
<u>The rule that links velocity, wavelength and frequency is:</u>
V = λν
<u>where:</u>
V is the velocity that we want to find
λ is the wavelength of sound = 1 m
ν is the frequency of the wave = 950 Hz
<u>Substitute to get the velocity as follows:</u>
V = 1 * 950 = 950 meters/sec
Now, we need to convert the meter/sec into Km/5 minutes
<u>We know that:</u>
To convert from meter to Km, we will divide by 1000
To convert from sec to minute, we will divide by 60 which means that, to convert from sec to 5 minutes, we will divide by 5*60 = 300
<u>Based on this:</u>
Hope this helps :)
Answer:
The false statement is 'Electric field lines form closed loops'.
Explanation:
- Electric field lines originate from positive end and terminates at negative end,i.e., field lines are inward in direction to the negative charges and outward from the positive charges.
- These lines when close together represents high intensity and when far apart shows low intensity of the field.
- These lines do not intersect, as the tangent drawn on these lines provides us with the field direction and intersection of these lines means two field directions which is not possible.
- These lines unlike magnetic field lines do not form closed loops as they do not turn around but originate at positive end and terminates at negative end which ensures no loop formation.
The inductive reactance of a 20.0-mh inductor at a certain frequency is 120 ω. 955hz is the frequency in hz
In physics, frequency is the number of waves that pass a fixed point in a unit of time as well as the number of cycles or vibrations that a body in periodic motion experiences in a unit of time.
How frequently something occurs is what is meant by the word frequency. A person blinking their eyelids 47 times in a minute is an example of frequency. the quality or state of happening frequently.
Frequency is a numerical value that expresses how frequently a specific item appears in the supplied data set. Grouped frequency distribution and Ungrouped In physics, frequency is a numerical value that expresses how frequently a specific item appears in the supplied data set. Distribution are the two different types of frequency tables.

Answer:
numbers
Explanation:
Virtually all unimaginable processes can be described as the movement of certain objects. To analyze and predict the nature of the movements that result from the different kinds of interactions, some important concepts such as momentum, force and energy have been invented. If momentum, force, and energy are known and expressed in a quantitative way (that is, by numbers) it is possible to establish rules by which the resulting movements can be predicted.
