Use acceleration = Final Velocity - Initial Velocity. So for the first one:
1.6m/s - 3.6m/s = -2.6m/s. This means the velocity changed by a negative amount so the acceleration is negative.
Answer:
as we find the resultant of the magnetic field we get in the xy plane. Just perpendicular to this plane i.e. along z-axis the charge is moving. Hence the force acting on the charge will also be in the xy plane.
Net field = ./(0.078^2 +0.070^2) = 0.105 T
Angle with x axis is arc tan 0.070/0.072 = 44.2 deg
So the force acting on the moving charge is got by Bqv
0.105*5.5*10^-5 * 6*10^3 = 0.03465 N
So the angle inclined by this force with x axis will be 90+44.2 = 134.2

Answer:
The stirring allows fresh solvent molecules to continually be in contact with the solute. If it is not stirred, then the water right at the surface of the solute becomes saturated with dissolved sugar molecules, meaning that it is more difficult for the additional solute to dissolve.

Explanation:
you are not a great man that you come from fever
From Ohm's law: R = V / I
Resistance = (voltage) / (current)
The first paragraph TELLS you that the current is always 0.5 A, and the table tells you the voltage across each piece of wire.
Again . . . <em>R = V / I</em>
