The beginning of the universe is from the big bang which is a massive explosion.
The Big Bang is the moment when the universe began 13.8 billion years ago with the explosion of a small, dense fireball. However, what caused the explosion in the first place remains a mystery.
A Big Bang event is a physical theory that explains how the universe expands from a dense and hot initial state. Various cosmological models of the Big Bang explain the evolution of the observable universe from the earliest known epochs to later large-scale forms.
In 1929, Edwin Hubble provided the first observational evidence that the age of the universe is finite. Using the largest telescope of its time, he discovered that the farther away a galaxy is from us, the more it appears that the space is expanding from us in all directions.

To solve this problem we need to use the induced voltage ratio law with respect to the number of turns in a solenoid. So
![\frac{\epsilon_2}{\epsilon_1} = -\frac{N_2}{N_1}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Cepsilon_2%7D%7B%5Cepsilon_1%7D%20%3D%20-%5Cfrac%7BN_2%7D%7BN_1%7D)
For the given values we have to
![N_1 = 400](https://tex.z-dn.net/?f=N_1%20%3D%20400)
![N_2 = 100](https://tex.z-dn.net/?f=N_2%20%3D%20100)
![\epsilon_2 = 120V](https://tex.z-dn.net/?f=%5Cepsilon_2%20%3D%20120V)
Replacing we have that,
![\frac{\epsilon_2}{120} = -\frac{100}{400}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Cepsilon_2%7D%7B120%7D%20%3D%20-%5Cfrac%7B100%7D%7B400%7D)
![\epsilon = 30V](https://tex.z-dn.net/?f=%5Cepsilon%20%3D%2030V)
Therefore the RMS value for secondary is 30V.
The current can be calculated at the same way, but here are inversely proportional then,
![\frac{I_2}{I_1} = -\frac{N_1}{N_2}](https://tex.z-dn.net/?f=%5Cfrac%7BI_2%7D%7BI_1%7D%20%3D%20-%5Cfrac%7BN_1%7D%7BN_2%7D)
Replacing we have
![\frac{I_2}{10mA} = -\frac{400}{100}](https://tex.z-dn.net/?f=%5Cfrac%7BI_2%7D%7B10mA%7D%20%3D%20-%5Cfrac%7B400%7D%7B100%7D)
![I_2 = 40mA](https://tex.z-dn.net/?f=I_2%20%3D%2040mA)
Therefore the rms value of current for secondary is 40mA
Then they will most likely slow down unless they do high knees or something like that
Answer:
lol what do you mean by this
Answer:
Motorcycle travel 39.75 m while coming to a stop
Explanation:
We have equation of motion
v = u + at
Final velocity, v = 0 m/s, u = 15 m/s, t = 5.3 s
0 = 15 + a x 5.3
a = -2.83 m/s²
Now we have the other equation of motion
v² = u² + 2as
0² = 15² - 2 x 2.83 x s
s = 39.75 m
Motorcycle travel 39.75 m while coming to a stop
