The scientific knowledge was necessary for Schrödinger’s work is the discoverd of electron.

<h3>What is electron and how was it discovered?</h3>

Thomson carried out new experiments that led him to conclude that cathode rays were formed by particles that have a negative charge. Later, Thomson proved that these rays were deflected by applying an electric field. Thus, these particles were called electrons.

The discovery of the electron allowed Schrodinger to explain quantum models that are based on how electrons behave.

Which of the following is not in our sun's future?

fenix001 [56]

The answer would not be A, because if the sun converts into a giant, the star will eventually become a white dwarf due to the fact it was previously a giant. Thus the answer would be B, since the sun does not become a supergiant.

dayshawn is traveling at 12 m/s away from the school. dayshaun's mom is looking for him because he is late coming home so she le

vivado [14]

Speed of Dayshawn travelling towards his home is 12 m/s

Speed of her mom towards his school is 5 m/s

They both starts at same time so whenever they will meet on their path the sum of the distance covered by Dayshawn and distance covered by his mom must be equal to the total distance of school and home

Now let say they both meet after "t" time when they starts motion

so we can write the total distance between school and home as

$d = v_1*t + v_2*t$

here d = 6492 m

$v_1 = 12 m/s$ = speed of dayshawn

$v_2 = 5 m/s$ = speed of his mom

now by solving the above equation

$6492 = 12t + 5 t$

$t = \frac{6492}{17}$

$t = 381.9 s$

so they will meet after 381.9 s from start which will be 3.36 minutes from there start

Also at this time the distance covered by her mom will be

$d_2 = v_2*t$

$d_2 = 5* 381.9 = 1909.4 m$

so they will meet at distance 1909.4 m from their home

Use this technique to find a formula for the intensity I of a sound, in terms of the sound level β and the reference intensity I

denis23 [38]

Answer:

$I = I_o (10^{\frac{\beta}{10}})$

Explanation:

As we know that sound level is given as

$\beta = 10 Log (\frac{I}{I_o})$

so here we have

$\frac{\beta}{10} = Log(\frac{I}{I_o})$

now we can take anti log both sides

$10^{\frac{\beta}{10}} = \frac{I}{I_o}$

so we have

$I = I_o (10^{\frac{\beta}{10}})$

so above is the expression for the intensity of sound in terms of reference intensity and sound level

A car is driving 55 miles per hour east. The car changes direction to head north but still travels at 55 miles per hour. Which i

bezimeni [28]

Answer:

Just as distance and displacement have distinctly different meanings (despite their similarities), so do speed and velocity. Speed is a scalar quantity that refers to "how fast an object is moving." Speed can be thought of as the rate at which an object covers distance. A fast-moving object has a high speed and covers a relatively large distance in a short amount of time. Contrast this to a slow-moving object that has a low speed; it covers a relatively small amount of distance in the same amount of time. An object with no movement at all has a zero speed.
