Answer:
Third → First → Second → Fourth
Explanation:
Initially helium and Hydrogen in abundance started to form atoms
Following the atoms formation by hydrogen and helium bombardment of new matter into the Earth took place.
The bombardment of matter resulted in separation of Earth into respective layers based on the weight of the matter.
A primitive ocean was created as a result of off gassing of the volcanoes.
Answer:
The magnetic field strength inside the solenoid is
.
Explanation:
Given that,
Radius = 2.0 mm
Length = 5.0 cm
Current = 2.0 A
Number of turns = 100
(a). We need to calculate the magnetic field strength inside the solenoid
Using formula of the magnetic field strength
Using Ampere's Law
![B=\dfrac{\mu_{0}NI}{l}](https://tex.z-dn.net/?f=B%3D%5Cdfrac%7B%5Cmu_%7B0%7DNI%7D%7Bl%7D)
Where, N = Number of turns
I = current
l = length
Put the value into the formula
![B=\dfrac{4\pi\times10^{-7}\times100\times2.0}{5.0\times10^{-2}}](https://tex.z-dn.net/?f=B%3D%5Cdfrac%7B4%5Cpi%5Ctimes10%5E%7B-7%7D%5Ctimes100%5Ctimes2.0%7D%7B5.0%5Ctimes10%5E%7B-2%7D%7D)
![B=0.005026=5.026\times10^{-3}\ T](https://tex.z-dn.net/?f=B%3D0.005026%3D5.026%5Ctimes10%5E%7B-3%7D%5C%20T)
(b). We draw the diagram
Hence, The magnetic field strength inside the solenoid is
.
The correct answer is option A. i.e. An important thing to consider when responding to a driver in front of you that stops suddenly is: the mental state of the other driver.
Our talk or discussion can disrturb the balance of the driver or he can get distracted. So, we must try not to speak much while the driver is driving because by doing this we are putting the life of ourselves in danger. Any distrcaction of driver can cause accident.
