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
When reviewing the correct answer is A
29.5 km/h is the answer you are looking for because 75 km in 5 hours is 15 km/h and 88km in 2 hours is 44 km/hr so if you add 15 and 44 and divide the answer, which is 59, by 2 because there are two numbers you will get 29.5
is there supposed to be a picture
precambrian is the correct answer
