<h3><u>Answer;</u></h3>
= 20.436 seconds
<h3><u>Explanation;</u></h3>
Speed = Distance × time
Therefore;
Time = Distance/speed
Distance = 7.50 m, speed = 0.367 m/s
Time = 7.50/0.367
<u>= 20.436 seconds </u>
Answer:
A homogeneous Mixture
Explanation:
The acid that contains the acetylsalicylic acid is a <u>mixture,</u> but it isnt a compound. though aspirin is. (hopefully this helps? qwq)
When calculated energy transferred between objects use the definition of heat as
Answer:
iv) It is 9x bigger than before
Explanation:
As the amplitudes of the new speakers add directly with the original one, taking into account the phase that they have, the composed amplitude of the sound wave is as follows:
At = A + 4A -2A = 3 A
The intensity of the wave, assuming it propagates evenly in all directions, is constant at a given distance from the source, and can be expressed as follows:
I = P/A
where P= Power of the wave source, A= Area (for a point source, is equal to the surface area of a sphere of radius r, where is r is the distance to the source along a straight line)
For a sinusoidal wave, the power is proportional to the square of the amplitude, so the intensity is proportional to the square of the amplitude also.
If the amplitude changes increasing three times, the change in intensity will be proportional to the square of the change in amplitude, i.e., it will be 9 times bigger.
So, the statement iv) is the right one.
The parents genotypes can be described as incomplete dominance since each parent provides a different allele of the given gene and none is dominating.
Heterozygous genotype is a process where by an offspring inherits different forms of a particular gene from each parent. .
Looking at the Punnett square, it is oblivious that the offspring inherited different version of the parents genes. This is shown by the presence of the two different letters indicated as Tt for all the four boxes in the Punnett square.
Thus, we can conclude that each parent provides a different allele of the given gene and none of the parents gene is dominating.
