Answer:
114.92749 keV
Explanation:
r = Radius of trajectory
m = Mass of electron = 
B = Magnetic field = 0.044 T
q = Charge of electron = 
The centripetal force and the magnetic forces are conserved
Velocity of first electron
Velocity of second electron
Total kinetic energy is given by
Converting to eV
The energy of incident electron is 114.92749 keV
<span>In the question "For safety concerning a curve, you should" the correct answer is "decelerate before the curve" (option A)
Decelerating before the curve gives you the opportunity to navigate the curve adequatery and be able to contain any on-coming vehicle.</span>
Answer:
The only incorrect statement is from student B
Explanation:
The planet mercury has a period of revolution of 58.7 Earth days and a rotation period around the sun of 87 days 23 ha, approximately 88 Earth days.
Let's examine student claims using these rotation periods
Student A. The time for 4 turns around the sun is
t = 4 88
t = 352 / 58.7 Earth days
In this time I make as many rotations on itself each one with a time to = 58.7 Earth days
#_rotaciones = t / to
#_rotations = 352 / 58.7
#_rotations = 6
therefore this statement is TRUE
student B. the planet rotates 6 times around the Sun
t = 6 88
t = 528 s
The number of rotations on itself is
#_rotaciones = t / to
#_rotations = 528 / 58.7
#_rotations = 9
False, turn 9 times
Student C. 8 turns around the sun
t = 8 88
t = 704 days
the number of turns on itself is
#_rotaciones = t / to
#_rotations = 704 / 58.7
#_rotations = 12
True
The only incorrect statement is from student B
Okay, so lets look at the equation.
The Skate accelerates at 2.0m/s². This can confuse some people but basically all you need to do is plug in the seconds.
So lets do 1 second. It would be 2.0m/1² which is 2.0m.
Lets do 2 seconds. It would be 2.0m/2² which is 0.5m.
Lets do 3 seconds. It would be 2.0m/3² which is 0.222m
Lets do 3.5 seconds which is about 0.163m.
Add those together and you get 2.885m.
This may be wrong but this is what I got given what you gave (that its seconds squared).
