Answer:
o.75
Explanation:
A train moving at a velocity of 15 m/s is accelerated to 24m/s over a 12 second period, time traveled by the train is 12 seconds.
The initial velocity u of the train is 15 m/s, the final velocity v is 24 m/s, and the time t is 12 seconds. The train is undergoing uniform acceleration.
We can use the kinematic equation to relate the initial velocity, final velocity, acceleration, and time:
v = u + at
Solving for t:
[tex]\[ t = \dfrac{v - u}{a} \][/tex]
Given that a is the acceleration and is calculated as:
[tex]\[ a = \dfrac{v - u}{t} \][/tex]
Substitute the given values:
[tex]\[ a = \dfrac{24 \, \text{m/s} - 15 \, \text{m/s}}{12 \, \text{s}} \][/tex]
[tex]\[ a = \dfrac{9 \, \text{m/s}}{12 \, \text{s}} \\\\= 0.75 \, \text{m/s}^2 \][/tex]
Now substitute the calculated acceleration back into the equation for \( t \):
[tex]\[ t = \dfrac{v - u}{a} \\\\= \dfrac{24 \, \text{m/s} - 15 \, \text{m/s}}{0.75 \, \text{m/s}^2} \][/tex]
[tex]\[ t = \dfrac{9 \, \text{m/s}}{0.75 \, \text{m/s}^2} \\\\= 12 \, \text{s} \][/tex]
Thus, the time traveled by the train is 12 seconds.

I need help right now lol,So the question is :During high tide, ocean waves often become larger. If the amplitude of a wave increases by a factor of 4, by how much does the energy increase?
Answer:
1.21 times
Explanation:
The energy of a wave is proportional to the square of the amplitude of the wave.
Mathematically:
e & a²
where
E is the energy of the wave
A is its amplitude
In this problem, the amplitude of the wave increases by a factor of 1.1; it means that the new amplitude can be written as
A=1.1A
Therefore, this means that the energy of the wave increases by a factor:
E' & A'²= (1.1A)² =1.1²A² =1.21A² =
1.21E
Therefore, the energy of the wave increases by a factor 1.21.:

A tall pea plant (Tt) is crossbred with another tall pea plant (Tt). The following Punnett square shows the separated alleles for two pea plants.
Which of the following shows the correct match of the box numbers and the genotype of the offspring?
Btw graph is below (ScreenShot)
Answer:
B.
Explanation:
when you use punnett squares, you cross the different genes with themselves. if T is in the first box on both sides, the genome will be TT. if the box lines up to tt, it will be tt. the boxes on the left use the genes' first letter and the boxes on the right use the second letter.
The result of the cross between Tt and Tt would be TT, Tt, Tt, tt.
Monohybrid crossingThis is a kind of crossing involving only one trait.
The genotype Tt will segregate to T and t respectively.
Crossing Tt and Tt:
Tt x Tt
TT Tt Tt tt
Thus, box 1 will contain TT, box 2 will contain Tt, box 3 will contain Tt, and box 4 will contain tt.
