Answer:
F = 0.114 N
Explanation:
a) The magnetic force is given by the equations
F = q v x B = I Lx B
the bold incate vector. This equation can be used in the form of magnitude and find the direction separately with the rule of the right hand
F = i L B sin θ
Where θ is the angle between the direction (L) and the magnetic field, if the two are perpendicular sin 90 = 1
Let's calculate
F = 3.30 0.127 0.272
F = 0.114 N
b) to know the direction of the magnetized field we must know the direction of B and L, but in the problem they tell us that they are perpendicular, but not the direction of each
Therefore, it can be reasonably concluded according to your
unfinished syllogism, that there are many people who do not
think scientifically.
Steam is often used as a central heating system when heating many buildings froma central location. So the correct option for the given question is option "D". Steam is actually generated ina single room or place mechanically or by useing fossil fuel or solar energy and then it is passed through pipelines to several rooms and buidings. This kind of system is mostly used when heating several rooms or building at once. Electric heaters are normally avoided as the cost of electricity is far higher than any other source of heating.
