Answer:
The correct answer to the question is
448 m/s
Explanation:
The fundamental frequency is the lowest resonant frequency of a vibration. The nature of a standing wave in a tube with one end closed which is at the the fundamental frequency is to have the node of the wave at the closed end and the wave anti-node at the opened end making a quarter of the wavelength.
Therefore the length of the gas column, 1.40 m = λ/4
So that λ = 4 × 1.4 = 5.6 m
Therefore from v = fλ
Where
f = frequency = 80.o Hz
v = wave speed
we have the wave speed v = 5.6×80 = 448 m/s
It would be not be able to move yet it would be in the air
Answer:A) This is most appropriate for an output measure of capacity.
Explanation: Toothpaste is a paste used to promote oral health and hygiene, Most toothpaste contain an active agent(floride) and it acts as an abrasive agent which helps to remove dental plaques or unwanted attachments to the teeth.
Among the options the Option(A) which says that THIS IS MOST APPROPRIATE FOR THE MEASURE OF CAPACITY is the statement that best Describes the situation. Toothpastes have a long history as it can be traced to about 4000years ago.
The magnitude of the average force that the ball exerts against his glove is 600 N
<h3>Further explanation</h3>
Newton's second law of motion states that the resultant force applied to an object is directly proportional to the mass and acceleration of the object.
F = Force ( Newton )
m = Object's Mass ( kg )
a = Acceleration ( m )
Let us now tackle the problem !
<u>Given:</u>
mass of ball = m = 0.15 kg
initial speed of ball = u = 40 m/s
final speed of ball = v = 0 m/s
distance = d = 20 cm = 0.2 m
<u>Asked:</u>
average force = F = ?
