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>
Answer:
true
Explanation:
electric charge is determined by electrons and protons, which are subatomic particles.
Answer:
The Artemis program is a U.S. government-funded international human spaceflight program that has the goal of landing the first woman and the next man on the Moon, specifically at the lunar south pole region, by 2024.

Answer: Δθ = 127.4 K
Explanation: by using the law of conservation of energy, the kinetic energy of the bullet equals the heat energy on the plate.
Kinetic energy of bullet = mv²/2
Heat energy = mcΔθ
Where m = mass of bullet = 0.09kg, v = velocity of bullet = 182 m/s, c = specific heat capacity of lead bullet = 130 j/kgk
Δθ = change in temperature
mv²/2 = mcΔθ
With 'm' on both sides of the equation, they cancel out each other, hence we have that
v²/2 = cΔθ
v² = 2cΔθ
Δθ= v²/2c
Δθ = (182)²/2×130
Δθ = 33124/260
Δθ = 127.4 K
Answer:
kg m/s
Explanation:
e = Charge = C
V = Voltage = 
c = Speed of light = m/s
Momentum is given by
The unit of MeV/c in SI fundamental units is kg m/s
