Paraphin [41]3 years ago

Answer:

I believe it's 8.09 seconds, but I'm rusty on my physics.

Explanation:

The equation for solving the time it takes for an object to fall is \sqrt{2d/g}

So multiply the distance times 2, and you get 642 meters. Then you divide by gravities acceleration constant, 9.8, and you get 65.51. Finally, \sqrt{65.51}, and you get 8.09 seconds.

I pulled the equation off of wikipedia and I'm unsure if it's the correct one, so hopefully this is correct. :/

Marina CMI [18]

The result of changing a physical sound wave into an analogous electrical signal using a transducer (such as a microphone) is called analogue audio. In this system, the rapid electrical level is directly proportional to the rapid air pressure taken by the transducer. The analogue signal is then augmented and can be kept on an analogue medium such as tape or transformed further into a succession of discrete mathematical numbers. The advantages of using this device is that it yields a subtle sound and is pleasing to the ear by pushing the signal level and overdriving it. But the disadvantages are editing it would be tedious and prone to degradation.

In a thunderstorm, electric charge builds up on the water droplets or ice crystals in a cloud. Thus, the charge can be considere
jolli1 [7]

1) 333.6 C

In order to have breakdown, the electric field at the surface of the cloud must be equal to the breakdown electric field:

E=3.00\cdot 10^6 N/C

The electric field strength at the surface of a charged sphere is given by

E=\frac{1}{4\pi \epsilon_0} \frac{Q}{R^2}

where

\epsilon_0 = 8.85\cdot 10^{-12} C^2/(N^2 m^2) is the vacuum permittivity

Q is the charge on the sphere

R is the radius of the sphere

Here we have a cloud of radius

R = 1.00 km = 1000 m

So we can re-arrange the previous equation in order to find the charge on the cloud:

Q=4\pi \epsilon_0 ER^2=4\pi (8.85\cdot 10^{-12})(3.00\cdot 10^6)(1000)^2=333.6 C

2) 2.08\cdot 10^{21} excess electrons

The total charge of the cloud must be (in magnitude)

Q = 333.3 C

We know that one electron carries a charge of

e = 1.6 \cdot 10^{-19}C

The total charge is just given by the charge of each electron multiplied by the number of excess electrons in the cloud:

Q=Ne

where

N is the number of excess electrons

Solving for N, we find:

N=\frac{Q}{e}=\frac{333.3 C}{1.6\cdot 10^{-19} C}=2.08\cdot 10^{21}

A cosmic ray muon with mass mμ = 1.88 ✕ 10−28 kg impacting the Earth's atmosphere slows down in proportion to the amount of matt
anyanavicka [17]

Answer:

a. the magnitude of the force experienced by the muon is 2.55 × 10⁻¹⁹N

b.  this force compare to the weight of the muon; the force is 1.38 × 10⁸ greater than muon

Explanation:

F= ma

v²=u² -2aS

(1.56 ✕ 10⁶)²=(2.40 ✕ 10⁶)²-2a(1220)

a=1.36×10⁹m/s²

recall

F=ma

F = 1.88 ✕ 10⁻²⁸ kg × 1.36×10⁹m/s²

F= 2.55 × 10⁻¹⁹N

the magnitude of the force experienced by the muon is 2.55 × 10⁻¹⁹N

b.  this force compare to the weight of the muon

F/mg= 2.55 × 10⁻¹⁹/ (1.88 ✕ 10⁻²⁸ × 9.8)

= 1.38 × 10⁸

VARVARA [1.3K]

The process of science followed my initial ideas e because it  involved experiments.

<h3>What is the process of science?</h3>

The process of science or the scientific method refers to the process which scientists follow in their discovery and explanation of natural phenomena.

The scientific method is given below:

  • making an observation,
  • develop a hypothesis,
  • making a prediction,
  • conducting an experiment
  • analyzing the results
  • propound a law

The process of science follows my initial ideas about the process of science because I always thought science involved experiments.

In conclusion, the process of science involves making hypothesis and conducting research.
