Two golf carts have horns that emit sound with a frequency of 394 Hz. The golf carts are traveling toward one another, each trav

eling with a speed of 9.5 m/s with respect to the ground. If one of the drivers sounds her horn, what frequency does the other driver hear? The speed of sound at the golf course is 345 m/s.

The frequency detected is 394 Hz. This question pertains to the Doppler effect, outlined by the equation fo = {c + vo}/{c - vs} × f. Here, fo is the observed frequency, c denotes sound speed at 345 m/s, vo is the observer's velocity of 9.5 m/s, and vs refers to the source's velocity of -9.5 m/s (the negative indicates opposite directions). The source's frequency is given as 394 Hz. Substituting the values leads to fo = {345 + 9.5}/{345 + 9.5} × 394. Simplifying yields fo = (354.5/354.5) × 394 = 1 × 394 = 394 Hz.

A plane takes off in san francisco at noon and flies toward the southeast. an hour later, it is 400 kilometers east and 300 kilo
Keith_Richards [3271]
This initial stage represents a right triangle. If the aircraft is positioned 400 km to the east and 300 km to the south of the origin while traveling in a straight path, you can form a right triangle with sides measuring 300, 400, and c. You might notice that these dimensions correspond to multiples of the Pythagorean triple 3, 4, 5, meaning that the length of c is 500 km. Alternatively, you would indicate
c^2 = 300^2+400^2 \\ c = 500.

For the second step, assuming I am correctly understanding "degrees south of east," it involves calculating the angle between the horizontal line indicating east and the trajectory of the aircraft. I created a diagram illustrating this (see attached). You could employ a trigonometric function related to one of the angles to find the solution. I selected
tan(C)= \frac{3}{4} \\ arctan( \frac{3}{4})=36.870. Therefore, I deduce that the angle is 37° south of east.

If white wool (W) is dominant over black wool (w), can two sheep with white wool produce an offspring with black wool? Explain y
inna [3103]
The response is affirmative .
An organism exhibiting the dominant phenotype can have two potential genetic combinations (for a gene with two alleles):
It might be homozygous dominant (WW) or
it can be heterozygous dominant (Ww), which is also known as a carrier

For instance, two black sheep can produce offspring with white wool if both are heterozygous dominant. In this scenario, both parents could pass on the recessive allele, resulting in their offspring inheriting the phenotype of white wool characterized by the genotype ww.

Sav [3153]

Answer:

529.15 m/s

Explanation:

h = Highest point = 70000 m

g = Gravitational acceleration = 2 m/s²

m = Sulfur's mass

Since both potential and kinetic energies are conserved

mgh=\dfrac{1}{2}mv^2\\\Rightarrow h=\dfrac{v^2}{2g}\\\Rightarrow v=\sqrt{2gh}\\\Rightarrow v=\sqrt{2\times 2\times 70000}\\\Rightarrow v=529.15\ m/s

The velocity at which the liquid sulfur exited the volcano is 529.15 m/s
