A length of wire is cut into 3 equal pieces. if each piece has a resistance of 0.20 , what is the resistance of the original length of wire?

The correct answer from each drop-down menu are in this case:

In a given mechanical system, in which forms of energy related to electromagnetic or thermal phenomena are not present, it can be said that the total energy of the system is purely mechanical. Thus, the Principle of Conservation of Energy implies the conservation of mechanical energy.

This, in turn, is the sum of the amounts of kinetic energy and various forms of potential energy (gravitational and elastic among them). Although mechanical energy is always constant, the amount of each of its components can change such that the total energy remains constant.

Explanation:

it is not a genetic mutation because it is completely natural and common unlike the other options.

As the box begins to oscillate, it will have minimum velocity at maximum displacement and maximum velocity at minimum displacement.

The force applied to box will cause a displacement of the box from equilibrium position to maximum position which increases as the applied force increases.

Therefore, as the box begins to oscillate, it will have minimum velocity at maximum displacement and maximum velocity at minimum displacement.

Explanation:

Answer:

Number of Wire Turns in the Coil.

Explanation:

The greater the number of turns of wire in the coil, the greater the inductance. Fewer turns of wire in the coil results in lesser inductance. More coils of wires indicate a greater amount of magnetic field force for a given amount of coil current.

Explanation:

Why can you get a shock if you touch a metal doorknob after walking across a wool carpet is because you have gained neutrons; the doorknob has fewer electrons. This is further explained below.

Electrons can be defined as a stable subatomic particles with a negative electrical charge that is found in all atoms and serves as the major carrier of electricity in solids.

In conclusion, You have an unbalanced charge, while the doorknob is neutral. you have gained neutrons; the doorknob has fewer electrons.

Answer:

F = F2 - F1     where F is the net force upwards

F = 5 - (.5 * 9.8) = (5 - 4.9) N = .1 N

Since there is a net force in the upwards direction the rocket should experience an upwards acceleration.

Answer:

  zero

Explanation:

The gravitational force between two masses is jointly proportional to the masses and inversely proportional to the square of the distance between them. The constant of proportionality is the universal gravitational constant.

__

In this scenario, the force to the right is matched by an identical force to the left from an identical mass at an identical distance. The magnitudes of the forces are equal, and their directions are opposite. The forces cancel.

The net force on the 2.2 kg mass in the center is zero.

Explanation: When the Moon passes between the Earth and the Sun, it casts a moving shadow on the Earth's surface, known as a solar eclipse. When the Earth passes between the Sun and the Moon, a lunar eclipse occurs, creating a shadow on the Moon.

Answer:

1)10 m/s

2) 20 m/s

3) 2 s

4) 500 m

5)1000 km/h

Average speed = distance travelled / time.

( note: distance must be in (m) and time in sec, if not then you convert ).

1) average speed = 20/2 = 10mls.

2) average speed = 100/5 = 20 m/s.

3) since we aren't given (time) let's call it x

so we replace the unknown time with x..

average speed = 2/x = 1

then cross multiply

you get x (the unknown time) as 2s {seconds}.

(to check if it's correct just add the time we got back into the equation and see if you would get a erage speed as 1m/s).

4) do the same, replace distance as x or any letter you want )

average speed = x/ 10 = 50

cross multiply

you get x = 500m {meters}

5) (we need to convert km to meters and time to secs because that's what we are working with).

200km = 200,000 m { to convert to meters you multiply the given by 1000, 1km = 1000m).

for 2h, we know that:

60 seconds makes 1 minute

60 minutes makes an hour.

so we multiply 60 by 60 we get 3600mins then we multiply it by 2 to get 7200 secs

so now

Average speed = 200,000/7200 = 27.77 m/s.

Here you go..

The most appropriate safety precaution that the archaeologist should take to protect against the alpha particles without overheating by wear a pair of normal leather gloves. Option D is correct.

The act of producing radiation spontaneously is known as radioactivity. This is accomplished by an unstable atomic nucleus that want to give up some energy in order to move to a more stable form.

Radiation is being employed to assist humanity in medical, academia, and industry, as well as to generate power.

Radiation is also important in agriculture, archaeology, space exploration, law enforcement, geology a variety of other fields.
