Answer:
The magnitude of the magnetic field is 0.83 T
Explanation:
Given :
Speed of electron inside television tube (<em>v</em>) = ×
Radius of electron moving path () = ×
According lorentz force in magnetic field is,
∴ ×
Where, = charge of electron, = speed of electron, = magnetic field and
= force on electron.
when electron is moving in circular orbit the force is given by,
∴
so we equate above both equation.
∴ ×
∴
∴ ××××××
∴ 0.83 Tesla
Therefore, the magnitude of the magnetic field is 0.83 T.
Answer:
Answer
Explanation:
The very first generation of star systems in the universe probably consisted only of hydrogen and helium. This means that,
There were no comets or asteroids in these first-generation star systems. As the comets and asteroids were the only soruce of elements other than Hydrogen and Heliums ( As starts mainly consists of helium and hydrogen).
The rate of displacement with time is called velocity
A comet speeds up as it approaches the Sun. Which statement about its kinetic energy is correct option is - (1) The comet has no kinetic energy because it is in outer space.
- Large ice and dust-based bodies known as comets circle the Sun. These ancient objects, which are best known for their long, streaming tails, are relics from the solar system's birth 4.6 billion years ago. The majority of comets are located outside of our solar system. Some are found in the Kuiper Belt, a vast disc that extends past Neptune's orbit. These are known as short-period comets. They orbit the Sun in lesser than 200 years.
- The Outermost Layer, the solar system's sphere-shaped outer edge, which is nearly 50 times further from the Sun than the Kuiper Belt, is home to additional comets. Because of how much longer it takes them to orbit the Sun, these are known as long-period comets. The comet with the longest known orbit completes one orbit in excess of 250,000 years.
