Answer:
When reviewing the correct answer is A
Explanation:
The magnetic force is given by the expression
F = qv xB
where the bold letters indicate vectors, from this expression the module can be calculated
F = = q v b sin θ
the direction of the force is given by the rule of the right hand, for a positive charge the speed held by the thumb, the extended fingers point in the direction of the magnetic field and the palm points the direction of the force
in this case
the speed is in the negative part of the z axis
the force is in the negative direction of the axis and
consequently the magnetizing field is in the positive direction of the x axis

Answer:
E = 5.5 10² N /C
Explanation:
For this exercise let's use Newton's second law
F = m a
the force is electric
F = q E
we substitute
q E = m a
E = 
(1)
the acceleration can be found with kinematics,
v = v₀ + a t
as the particle starts from rest v₀ = 0
a = v / t
a = 160 / 2.90
a = 55.17 m / s²
the relationship
q / m = 0.100 C / kg
m / q = 10 kg / C
we use equation 1
E = 10 55.17
E = 551.7 N / C
E = 5.517 10² N / C
ask for the result with two significant figures
E = 5.5 10² N /C
Answer:
moving
Explanation:
They've been moving for thousands and thousands of years. Millions of years ago there was a land called Pangea that seperated into the continents we see today.
