Welll ... if you read the question, you'll see what a jumbled mess you actually
posted, but I think I can pull enough out of it to give you some answers.
<span>One
light bulb in a string of lights goes out. This causes all of the
other
lights in the string to also go out. The entire string of lights
must be one series circuit.
2. When a switch is turned from the off to the on position,
an open circuit is changed to a closed circuit.
3.Early telephone poles had wires that connected inside bell-shaped
glass enclosures like the ones shown below. (nothing is shown below)
several bell-shaped glass enclosures
These glass enclosures helped to
keep the electric current from moving
outside the circuit of wires. The
glass enclosures were used as insulators.
4.Use Ohm’s Law
to determine the resistance in a circuit if the
voltage is 12.0 volts
and the current is 4.0 amps.
Ohms law: Resistance = (voltage) / (current)
= (12.0 v) / (4.0 amp)
= 3 ohms .
5. "In a closed circuit, the
current only flows from the power source
to an electrical device such
as a lamp."
This statement is false. The current eventually has to get back
to the power source. If it doesn't then there's no 'circuit', and
nothing works. That's a big part of the reason why the plug
has 2 prongs on it, and the cord from the plug to the lamp
has 2 wires in it. </span>
For a system released from rest at θ = 0° when a constant couple moment M = 100 N.m is applied, the speed of the 10-kg block is mathematically given as
V=4.33m/s
<h3>What is the speed of the 10-kg block?</h3>
Generally, the equation for the workdone is mathematically given as
W=T tehta<dtheta
W=100(90*\pi/180)
W=1.5707*100
W=1.57Nm
The change in potential energy across the pulley
dP=mgh
dp=10*9.81*111.8
dp=10.97J
For the thrid position, potential energy is
dP=mg(0.3)
dP=17.658J
dP'=17.658J-13.125
dP'=-4.532J
For 2nd position dP=0
The change in Kinectic energy across the pulley\
dK.E=0.5mv^2
For 1st
dk.E=0.5m(10)^2
2nd
dK.E=0.5Iw^2
dK.E=0.5(7.5*10^-3)(v^2/0.05)^2
3rd
2nd=3rd
In conclusion,
157.07=dKE+dP.E
157.07=5v^2+ (7.5*10^-3)(v^2/0.05)^2+10.97-4.53
V=4.33m/s

Answer:
the package has probably not arrived due to mail overloads and packing shortage . mail may be delayed because of external circumstances that change transit times. You can call your local post office to see if your package is there, or wait for your tracking to update to delivered. It will not update to delivered until your mailman actually scans it at your mailbox or door.
