Answer:
(b) EAST
Explanation:
you can assume that the magnetic field points rightward, that is, in the positive x direction (NORTH). Furthermore, you can assume that the direction of the motion of the electron is in the positive y direction. Hence, you have:
You use the Lorentz formula to known which is the direction of the magnetic force over the electron:
which implies the cross product between the unitary vecors j and i, that is
(WEST)
However, the minus sign of the charge of the electron changes the direction 180°. Hence, the direction is k. That is, to the EAST
Answer:
1.A satellite maintains its orbit by balancing two factors: its velocity and the gravitational pull that Earth has on it.
I'm sorry I only know the first one
<span>6.5 m/s
An object's momentum is its speed (m/s) multiplied by its mass(kg).
initial momentum of target = 0.3kg x 2.4m/s = 0.72
initial momentum of arrow = 0.0225kg x 38.5m/s = 0.86625
resulting momentum of arrow is 0.86625 - 0.72 = 0.14625
momentum /mass = speed
so 0.14625 /0.0225 = 6.5 m/s</span>
