Speed equals distance divided by time, so 350 divided by 2.5 equals 140 kilometers per hour.
The correct answer is C. amplitude.

Answer:
2.5% of the earth's fresh water is unavailable: locked up in glaciers, polar ice caps, atmosphere, and soil; highly polluted; or lies too far under the earth's surface to be extracted at an affordable cost.
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
