Answer:
cheetah goes 52.2 m in that time.
Explanation:
When using the right-hand rule to determine the direction of the magnetic force on a charge, which part of the hand points in the direction that the charge is moving? The answer is <span>thumb.
</span>One way to remember this is that there is one velocity, represented accordingly by the thumb. There are many field lines, represented accordingly by the fingers. The force is in the direction you would push with your palm. The force on a negative charge is in exactly the opposite direction to that on a positive charge. Because the force is always perpendicular to the velocity vector, a pure magnetic field will not accelerate a charged particle in a single direction, however will produce circular or helical motion (a concept explored in more detail in future sections). It is important to note that magnetic field will not exert a force on a static electric charge. These two observations are in keeping with the rule that <span>magnetic fields do no </span>work<span>.</span>
Answer:
n a static situation the membrane has a charge distribution of −2.5 × 10 −6 C/m 2 on its inner surface and +2.5 × 10 −6 C/m 2 on its outer surface. Draw a diagram of the cell and the surrounding cell membrane. Include on this diagram the charge distribution and the corresponding electric field.
This occurs due to convection! warm air (and water) rises and the cold sinks!
Answer:
k = 7.32 N/m
Explanation:
We know that the time period of a spring mass system is given as follows:
T = 2π√(m/k)
T² = 4π²m/k
k = 4π²m/T²
where,
k = force constant = ?
m = mass = 0.019 kg
T = Time Period = 0.32 s
Therefore,
k = 4π²(0.019 kg)/(0.32 s)²
<u>k = 7.32 N/m</u>
