W = m g weight of drop
W = q E
m = q E / g = = 3 e E / g
m = 3 * 1.6E-19 * 1.4E4 / 9.8 = 6.96E-16 kg
Speed = 8000m/20min = 400m/min
Convert meters/min to meters/second.
60seconds in 1minute:
400m/60sec = 6.67m/s
Speed is: 6.67m/s
Here is the highly detailed, arcane, complex, technical form of Ohm's Law that is needed in order to answer this question ===> V = I · R .
Voltage = (current) x (resistance)
Voltage = (2 Ampere) x (8 Ω)
<em>Voltage = 16 volts</em>
Answer & Explanation:
Definition:
Mass informs us about how much matter is present in a body. It is the measure of the inertia of a body. It can be measured by measuring the force of gravity acting on it on earth.
On the other hand, Momentum is the quantity of motion of the body. It depends depends upon velocity and the direction of the motion of the body.
Unit:
The SI unit of mass is kilogram (kg) while the SI unit of momentum is kg.m.s-1.
Formula:
Mass = Momentum / Velocity
Momentum = Mass * Velocity
or p = mv
Type:
Mass is scalar quantity while Momentum is a vector quantity.
The correct answer is <span>A. By multiplying the change in mass by the square of the speed of light since the formula is expressed by </span>E = mc².
