Answer:
The probability her 4th child will be a girl is 0.5
Explanation:
during pregnancy or child birth, the gender of a baby is not affected by the gender of the previous baby in the womb. Rather it is determined by the type of chromosomes supplied by the father of the baby.
If X chromosomes are supplied, a girl will be born because the baby will have xx chromosomes. If Y chromosomes are supplied, the baby will have YY chromosomes which means that he is a boy.
Hence there are equal chances of the baby being a boy or a girl, each time a woman is pregnant. The probability of the baby being a boy or a girl is the same and it 0.5
I think it will stay the same.
The frequency of wavelength of 1km <u>299792.458 Hz.</u>
These molecules already react to the inward motion of the loudspeaker membrane moving toward the source. Frequency and wavelength are inversely proportional to each other. The wave with the greatest frequency has the shortest wavelength. Twice the frequency means one-half the wavelength. For this reason, the wavelength ratio is the inverse of the frequency ratio.
calculation:-
C= wavelength × frequency
frequency = 3 × 10⁸/ 1000 Hz
= 299792.458 Hz.
= 3 ×10⁵ Hz
Based on such a model, we found that mass is not an intrinsic property of the particle. Instead, mass is basically a measure of particle energy. The relations between energy and mass can be directly derived based on the wave properties of the particle. Waves are one of the ways in which energy may be transferred between stores. Waves can be described as oscillations or vibrations about a resting position.

Since pressure is connected to force, the force on a wall is
straightly proportional to the square of the velocity times the mass. The ratio
of the molecular weights of the CO2 and SO2 is (64.066 / 44.01) = 1.456. But,
we are not yet done. The actual rms velocity has to be taken as the square root
of that number, so the answer is 1.206.
The answer is C. The specific amount of energy emitted when electrons jump from excited states to the ground state refers to emission spectrum. The energy is emitted in the form of photons, and the photons have very specific wavelengths (energy) that correspond to the energy gaps between the excited states and the ground state. The specific wavelengths of light emitted are referred to as the "emission spectrum," and each element produces a different emission spectrum. Thus, this emitted energy can be used to identify the element from which your sample was taken.
