Answer:
1.5 m/s/s
Explanation:
This problem can be solved using equation of motion given below
where v is the final velocity
u is the initial velocity
t is the time
given
final velocity = 9 m/s
initial velocity = 0 m/s
t = 6 seconds
lets substitute these value in v = u + at
9 = 0 + a*6
=> 9 = 6a
=> a = 9/6 = 3/2 = 1.5
Thus, acceleration is 1.5 m/s/s
I am pretty sure the answer is transformed or converted.
Answer:
Noise cancelling headphones have a microphone which listens to the ambient noise. The headphone then processes the sound and provides a wave to produce destructive interference. This cancels the ambient noise.
Explanation:
First, let us understand what interference is. Interference is the phenomenon that occurs when two waves superpose to form a wave which has a different wavelength, frequency, amplitude than the original two waves. When the crest of one wave superposes with the other waves crest then this results in the amplitude increasing. This is known as constructive interference. When the crest of one wave superposes with the other waves trough then this results in the amplitude decreasing. This known as destructive interference.

The correct words to fill the given blanks would be as follows:
- Peak
- Trough
- Equilibrium Line
- Oscillation
- Frequency, Hertz
- Period, seconds
- The "peak" is denoted as the highest or maximum point that the wave attains while 'Trough' is characterized as the base of the wave.
- The 'equilibrium line' is characterized as the extent to which the wave flattens or compresses.
- Oscillation is defined as the process in which an object moves in the "back and forth motion."
- Frequency is the amount of occurrences that waves travel in a second which is denoted in the terms of Hertz.
- Lastly, period is the duration required by wave to accomplish one motion is denoted in terms of seconds.
- Amplitude is the breadth or magnitude of the waves.

Answer:
Negative
Explanation:
First law of thermodynamic also known as the law of conservation of energy states that the total energy of an isolated system is constant; energy can be transformed from one form to another, but can be neither created nor destroyed.
The first law relates relates changes in internal energy to heat added to a system and the work done by a system by the conservation of energy.
The first law is mathematically given as ΔU = - = Q - W
Where Q = Quantity of heat
W = Work done
From the first law The internal energy has the symbol U. Q is positive if heat is added to the system, and negative if heat is removed; W is positive if work is done by the system, and negative if work is done on the system.
Analyzing the pistol when it raises in isothermal and when it falls in isobaric state.The following can be said:
In the Isothermal compression of a gas there is work done on the system to decrease the volume and increase the pressure. For work to be done on the system it is a negative work done then.
In the Isobaric State An isobaric process occurs at constant pressure. Since the pressure is constant, the force exerted is constant and the work done is given as PΔV.If a gas is to expand at a constant pressure, heat should be transferred into the system at a certain rate.Isobaric is a fuction of heat which is Isothermal Provided the pressure is kept constant.
In Isobaric definition above it can be seen that " Heat should be transferred into the system ata certain rate. For heat to be transferred into the system work is deinitely been done on the system thereby favouring the negative work done.
