The time taken by the train will be 13.84 sec. Time taken is the ratio of the distance and speed.

Distance is a numerical representation of the distance between two objects or locations.

Distance can refer to a physical length or an estimate based on other factors in physics or common use. |AB| is a symbol for the distance between two points A and B.

Distance is found as the product of the speed and velocity.

Distance = speed × time

time = Distance/speed

time= 1275 (m)/92.1( m/sec)

time(t) =13.84 sec

Hence, the time taken by the train will be 13.84 sec

The the amount of the original gold-198 that remains after 5.4 days is one-quarter.

Half-life is the time required or taken for half the amount of matter present in a given substance to vanish or decay.

The half-life of gold-198 is 2.7 days.

After, 5.4 days, the gold would have undergone two half-lives.

The amount of matter remaining = 1/2 * 1/2 = 1/4

Therefore, the amount of the original gold-198 that remains is one-quarter.

Based on the calculations, the radius of this cone is equal to 4 inches.

Mathematically, the volume of a cone is calculated by using this formula:

V = 1/3 × r²h

Where:

Making r the subject of formula, we have:

r = √(3V/πh)

Substituting the given parameters into the formula, we have;

r = √(3 × 96π/π × 18)

r = √(288/18)

r = √16

Radius, r = 4 inches.

Answer:

No, there are multiple ways in which different mutations in the same gene can cause the same phenotype

Explanation:

Several different mechanisms of mutation can lead to the same phenotype. For example, lets say our phenotype is that flies have white eyes, and we know that this occurs in one particular gene that normally makes the eye colour red. (the red gene)

These mutations likely rendered the red gene ineffective (as the eyes are not red). However, this could happen in a variety of ways.

There could be a single base deletion in the first exon of the mRNA, changing the reading frame of the protein and messing up the entire sequence (a frame shift mutations)

The entire gene could be deleted

A single base could be substituted in an important site of the gene, for example, one which translates into a catalytic residue or binding site in the protein

There could be an inversion at the promoter region of the gene, such that a transcription factor can no longer bind to transcribe the gene.

There are countless other ways in which a mutation could have been caused. Therefore, just because we know the same gene is affected does not mean that we can assume the mutations are identical.

Answer:

Distance: 32 km

Displacement: 18 km

Explanation:

Distance is the total amount travelled. Displacement on the other hand is how far away an object is from its starting point.

Distance is a scalar quantity meaning it only has magnitude. Displacement is a vector quantity meaning it has magnitude and direction.

Distance is represented by "x" while displacement is represented as "Δx".

Note that "Δ" is the Greek letter "delta" which is used to represent a change in something.

Let's start by finding the distance.

Since distance is the total amount travelled, we can just add all of the values.

9km + 18km + 5km = 32 km

Then, we can find the displacement.

North and East are positive while South and West are negative.

If the athlete ran 9km East and 5km West, their displacement would be:

9km - 5km = 4km East

Now, we can set up a triangle to determine the displacement from the starting point.

18km North would be the longer leg, 4km East would be the shorter leg, and the displacement would be the hypotenuse.

Using Pythagorean's Theorem we find that:

[tex]a^2+b^2=c^2\\4^2+18^2=c^2\\16+324=c^2\\340=c^2\\c\approx18[/tex]

Note that "a" and "b" represent the legs of the triangle while "c" represents the hypotenuse of the triangle.

The displacement is approximately 18m.

Answer:

Blue light has the shortest wavelength amongst all the colours that combine to make white light. This means the blue light diffracts (bends) the most out of all of them. There will be no dispersion of colours because ideally, the blue light must consist of only one frequency.

Note that

Like charges attract each other and unlike charges repel each other

The drawing of the positive charge showing the electrical fields inside  the empty volume enclosed by the shell is attached accordingly. See explanation below.

The electrostatic potential at any location outside the shell, assuming the center of the shell is Z, equals Z/4π∈₁r, where r is the distance from O.

It's also worth noting that the spherical shell's outer surface is an equipotential shell, which means that the electric field at any place inside the shell except O is zero.

Because the shell is metallic, charge Z will induce uniformly on the inner surface and +Z will induce uniformly on the outer surface, with O as the charge center.

As a result, an electric field will exist both within and outside the shell, but the total charge will remain the same.

Answer:

200ft

Explanation:

To find out how much distance the man covered, you need to find the perimeter of the rectangle. To find the perimeter of a rectangle, the formula is:

P = (L + H) × 2

Step 1

Plug in the values for L and H.

P = (70 + 30) × 2

Step 2

Add 70 and 30, because you need to add parentheses first.

P = (100) × 2

Step 3

Remove parentheses, and multiply 100 by 2.

P = 100 × 2

P = 200

Thus, the man walked 200 feet in distance.
