An electron is moving through a magnetic field whose magnitude is 9.21 × 10^-4 T. The electron experiences only a magnetic force
Marysya12 [62]

Answer:

\theta=10.60^{\circ}

Explanation:

Given that,

Magnetic field, B=9.21\times 10^{-4}\ T

Acceleration of the electron, a=2.3\times 10^{14}\ m/s^2

Speed of electron, v=7.69\times 10^{6}\ m/s

The force due to this acceleration is balanced by the magnetic force as :

ma=qvB\ sin\theta

sin\theta=\dfrac{ma}{qvB}

sin\theta=\dfrac{9.1\times 10^{-31}\times 2.3\times 10^{14}}{1.6\times 10^{-19}\times 7.69\times 10^{6}\times 9.21\times 10^{-4}}

\theta=10.60^{\circ}

So, the angle between the electron's velocity and the magnetic field is 10.6 degrees. Hence, this is the required solution,

Collaborative learning focuses on the learning of an individual. True or False
Jobisdone [24]

Answer:

False

Explanation:

The collaborative learning is not a type of learning that focuses on individual learning. This type of learning focuses on joint learning between two or more individuals that act as a team. The collaborative learning is a method that encourages the two or more individuals to work together, to capitalize on each other's skills and resources for the benefit of the whole, for the team. This type of learning has its own supporters and critics, as some consider it as excellent way to develop the team work and closer bonds between the people, while others argue that it is destroying the potential of the individual.
