Electric force depends on the charge and the strength of the electric field. The equation that relates the three:
F = Eq where q is the charge and E is the electric field strength.
Answer:
Legalistic
Explanation:
Legalistic style of policing is a part of operational procedures that involves total enforcement of law to the letter with a minimal use of force but already stipulated law and consequence for a particular offence. For instance if a driver is caught going over the speed limit a ticket is issued immediately based on the law
Answer:
a) 12.8212 N
b) 12.642 N
Explanation:
Mass of bucket = m = 0.54 kg
Rate of filling with sand = 56.0 g/ sec = 0.056 kg/s
Speed of sand = 3.2 m/s
g= 9.8 m/sec2
<u>Condition (a);</u>
Mass of sand = Ms = 0.75 kg
So total mass becomes = bucket mass + sand mass = 0.54 +0.75=1.29 kg
== > total weight = 1.29 × 9.8 = 12.642 N
Now impact of sand = rate of filling × velocity = 0.056 × 3.2 = 0.1792 kg. m /sec2=0.1792 N
Scale reading is sum of impact of sand and weight force ;
i-e
scale reading = 12.642 N+0.1792 N = 12.8212 N
<u>Codition (b);</u>
bucket mass + sand mass = 0.54 +0.75=1.29 kg
==>weight = mg = 1.29 × 9.8 = 12.642 N (readily calculated above as well)
Distance = speed* time
10x10^-3 *u + 10x10^-3 * 2u = 125
0.01u + 0.02u = 125
0.03u = 125
u = 4166.66666.... s
acceleration = (final velocity - initial velocity)/time
(10x10-3 - 0)/4167 = 2.3998 * 10^-6 m s-2
