Answer:

<u> data from his experiments</u>

<u>Explanation:</u>

Interestingly, at the time Gregor Mendel primarily performed experiments with pea plants and then recorded his results.

In fact, it is believed that Mendel's genetic experiments took a period of about eight years (1856-1863) after which he published data from his experiments in 1865. It was this data from his experiments with pea plants that led to his development of the theory of inheritance.

What does the ideal gas law allow a scientist to calculate that the other gas laws do not?
Anvisha [2.4K]

The ideal gas law allows a scientist to calculate the number of moles that the other gas laws do not. The ideal gas law is given as

P V = n RT

rearranging the equation by dividing both side by "RT", we get

PV/(RT) = nRT/(RT)

n = PV/(RT)

inserting the values of pressure, volume and temperature, we get number of moles.

Three electromagnetic waves travel through a certain point P along an x axis. They are polarized parallel to a y axis, with the
chubhunter [2.5K]

Answer:

4.846*10^{-5} sin(5*10^{14}t )

Explanation:

Frequency of each electromagnetic wave is same thus we can interfere them along X axis in Phase diagram.

In phase diagram indicate each wave as vector with amplitude as length and phase difference as angle. (shown in attachment)

Now take component of E2 and E3 amplitude along X direction.

Net amplitude of all E in X direction = 4*10^{-5} + cos(45)[ 6*10^{-6} +  6*10^{-6} ]

⇒  4.846*10^{-5}

Final resultant have no change in frequency

So , resultant is 4.846*10^{-5} sin(5*10^{14}t )

Earthquake waves are 35m long and arrive at a frequency of 2.0Hz. How fast are they travelling?
Nitella [24]

Answer:

70 m/s

Explanation:

The frequency of earthquake = 2.0 Hz

The wavelength = 35 m

How fastbthw earthquake is t traveling is given bythw velocity of the wave, velocity of wave is related to frequency and wavelength using the formula :

V = frequency * wavelength

V = 2 * 35

V = 70 m/s
