Magnetic torquer
or torque rod are essentially sets of electromagnets that are laid out to create a
magnetic field that interfaces with an ambient magnetic field, so that the
counter-forces produced is a stronger magnetic force. In addition, its magnetic
field strength increases with the current due to the rod that has field lines
pointing in the same direction, closed together and nearly parallel with uniformly
spaced. This set up indicates that the field of a torque rod produced powerful
magnetic field than a torque coil.
Answer:
The answer is 1250 mm
Explanation:
The path that particles move in the spectrometer is semicircular. Each of the particles has a displacement of twice the radius (2r) from the entrance to where the film is hit. According to the exercise, if the separation between the two molecules is 0.25 mm, then the difference in the radius of the molecules is equal to 0.125 mm. The ratio of mass/radius is equal for molecules, and therefore is equal to:
m = q * B * r / v
m/r = constant
(m/r)CO = (m/r)N = (28.0106 u/r) = (28.0134 u/(r + 0.000125 m))
Clearing and solving r:
r = 1.25 m = 1250 mm
Answer:
to the left.
Explanation:
We can use the equation where v is the velocity at time t and the velocity at . Since we want the acceleration we write this equation as:
Considering the <em>direction to the right as the positive one</em>, we have at , and at , so we substitute:
Where the minus sign indicates it is directed to the left.
Answer:
A force is any interaction that, when unopposed, will change the motion of an object
Explanation:
Answer:
D.
The forces on the book are balanced because the gravity pulling down on the book is equal to the upward force applied by the table.
