An electron and a proton are initially very far apart (effectively an infinite distance apart). They are then brought together t
Lina20 [59]

Answer:

dU=-4.36*10^{-18}J

Explanation:

From the question we are told that:

Average distance d_{avg} =5.29*10^{-11}m

Generally the equation for change in electric potential energy is mathematically given by

dU=u_f-U_1

Where

U_1=0 Because of initial lengthy distance apart

And

U_f=\frac{kq_eq_p}{d}

U_f=\frac{9*10^9*1.6*10^{-19}*-1.6*10^{-19}}{5.29*10^{-11}}

U_f=-4.36*10^{-18}J

Therefore

dU=u_f-U_1

dU=-4.36*10^{-18}J-0

dU=-4.36*10^{-18}J

The equation for power is represented as P=fd/t. Identify the relationship between P and t
Arlecino [84]
P is disproportional to t, which means that if P increases with x factor, the t will decrease with the same x factor. If t increases then P decreases

A drag racer starts from rest and accelerates at a constant 16.0m/s^2 until it reachs its top spees of 407km/hr. how far does it
svlad2 [7]

Answer:

Distance, s = 399.42 m/s

Explanation:

It is given that,

Initial velocity of drag racer, u = 0

Final velocity of drag racer, v = 407 km/hr = 113.056 m/s

Acceleration, a=16\ m/s^2

Third equation of motion is :

v^2-u^2=2as

s is the distance traveled

s=\dfrac{v^2-u^2}{2a}

s=\dfrac{v^2}{2a}

s=\dfrac{(113.056)^2}{2\times 16}

s = 399.42 m/s

So, the distance traveled during this acceleration is 399.42 m/s. Hence, this is the required solution.

Which feature of a soundwave is related to pitch
almond37 [142]

Answer:

Frequency

Explanation:

As we know that the characteristics of sound is as following

Loudness : loudness of sound depends on the amplitude of sound so  increasing the loudness will cause the amplitude to increase.

Quality of sound : Quality of sound depends on the type of waveform. For different waveform the quality of sound is also different.

Pitch of sound : Pitch depends on the frequency of the sound which means if the frequency of sound is more then its frequency will be more

the correct answer will be

Frequency
