Missing questions: "find the speed of the electron".
Solution:
the magnetic force experienced by a charged particle in a magnetic field is given by

where
q is the particle charge
v its velocity
B the magnitude of the magnetic field

the angle between the directions of v and B.
Re-arranging the formula, we find:

and by substituting the data of the problem (the charge of the electron is

), we find the velocity of the electron:
Answer:

Explanation:
Given


Required
Determine the speed of the jet
The speed is calculated as:

Substitute 4800 km for Distance and 6hr for Time


<em>Hence, the speed of the commercial jet is 800km/hr</em>
A simple pendulum that takes 32 sec. to complete 20 oscillations has a time period of 10 min. and 6 sec.
Because they are mentally trying to extinguish the negative things in their lives and focus on the positive things
Answer: When it comes to energy saving, energy management is the process of monitoring, controlling, and conserving energy in a building or organization. Typically this involves the following steps: Metering your energy consumption and collecting the data.
