Answer:uranus
Explanation:it sounds weird
Answer:
Pi(3.14) radians or 180º degrees
Explanation:
First of all, we need to obtain the wavelength of a wave traveling to the speed of sound and 420 Hz of frequency.
The formula is:
![l=wavevelocity/frequency](https://tex.z-dn.net/?f=l%3Dwavevelocity%2Ffrequency)
where l = wavelength in meters
With current values:
l = 336 [m/s]/420[1/s] = 0.8 meters
Since a complete cycle (360º or 2pi radians) needs 0.8 meters to complete, 0.4 meters or 40 cm is just half of it, making a 180º degree phase or 3.14 radians.
Answer:
Desiree should collect data, which may support or refute her hypothesis.
Explanation:
The next step Desiree must take is to collect data which might likely support or refute her hypothesis.
This is usually done by carrying out experiments or field studies.
- The scientific method provides the steps through which knowledge of science is investigated.
- It usually starts with observation.
- After an observation is made, a scientific question is asked.
- This leads to the development of hypothesis.
- Then, experiments are carried out and data collect to either bolster the claim or refute it.
- Interpretation follows and conclusion is draw.
<h3><u>Answer;</u></h3>
It favors the movement of chloride ions from the inside to the outside of the cell.
<h3><u>Explanation;</u></h3>
- Electrochemical gradient refers to a gradient of electrochemical potential, normally for ions that can move across a membrane.
- Normally sodium (Na+) and chloride (Cl−) ions are at high concentrations in the extracellular region, and low concentrations in the intracellular regions.
- Assuming the chloride ions are equal on both sides of the membrane the electrochemical gradient for chloride ions favors the movement of chloride ions from the inside to the outside of the cell.
Answer:
Wavelength = 1.36 * 10^{-34} meters
Explanation:
Given the following data;
Mass = 0.113 kg
Velocity = 43 m/s
To find the wavelength, we would use the De Broglie's wave equation.
Mathematically, it is given by the formula;
![Wavelength = \frac {h}{mv}](https://tex.z-dn.net/?f=%20Wavelength%20%3D%20%5Cfrac%20%7Bh%7D%7Bmv%7D%20)
Where;
h represents Planck’s constant.
m represents the mass of the particle.
v represents the velocity of the particle.
We know that Planck’s constant = 6.6262 * 10^{-34} Js
Substituting into the formula, we have;
![Wavelength = \frac {6.6262 * 10^{-34}}{0.113*43}](https://tex.z-dn.net/?f=%20Wavelength%20%3D%20%5Cfrac%20%7B6.6262%20%2A%2010%5E%7B-34%7D%7D%7B0.113%2A43%7D%20)
![Wavelength = \frac {6.6262 * 10^{-34}}{4.859}](https://tex.z-dn.net/?f=%20Wavelength%20%3D%20%5Cfrac%20%7B6.6262%20%2A%2010%5E%7B-34%7D%7D%7B4.859%7D%20)
Wavelength = 1.36 * 10^{-34} meters
