Answer:

B. The circuit would have less resistance.

Explanation:

When the lightbulb is replaced in the circuit by a wire, the circuit will have less resistance.

Resistance is the the opposition to the flow of current within a circuit. Both a light bulb and wire are two examples of resistors in a circuit.

  • A wire has a low value of resistance compared to the bulb.
  • This is why the overall resistance will reduce when a light bulb is replaced with a wire.

Differentiating States of Matter
ladessa [460]

Answer:

The state of matter in Gas state has the greatest amount of particle movement.

Explanation:

Matter is classified generally in three states of matter and that is solid state, liquid state and gas state. So each state has its own properties and arrangement of atoms. If we consider solid state, the atoms will be bonded very close to each other and thus the movement of particles or atoms are very much restricted in a solid state. If we consider liquid state, then the atoms will be somewhat loosely bonded compared to solid and so the particles can be somewhat flexible to move from their original position. While for gaseous state, they are the most loosely connected state and so the atoms can move as freely as possible with no restrictions. Thus the gas state of matter has the greatest amount of particle movement among the given choices.

A 2.0-cm-diameter parallel-plate capacitor with a spacing of 0.50 mm is charged to 200 V?What is the total energy stores in the
Rama09 [41]

1) 1.11\cdot 10^{-7} J

The capacitance of a parallel-plate capacitor is given by:

C=\frac{\epsilon_0 A}{d}

where

\epsilon_0 is the vacuum permittivity

A is the area of each plate

d is the distance between the plates

Here, the radius of each plate is

r=\frac{2.0 cm}{2}=1.0 cm=0.01 m

so the area is

A=\pi r^2 = \pi (0.01 m)^2=3.14\cdot 10^{-4} m^2

While the separation between the plates is

d=0.50 mm=5\cdot 10^{-4} m

So the capacitance is

C=\frac{(8.85\cdot 10^{-12} F/m)(3.14\cdot 10^{-4} m^2)}{5\cdot 10^{-4} m}=5.56\cdot 10^{-12} F

And now we can find the energy stored,which is given by:

U=\frac{1}{2}CV^2=\frac{1}{2}(5.56\cdot 10^{-12} F/m)(200 V)^2=1.11\cdot 10^{-7} J

2) 0.71 J/m^3

The magnitude of the electric field is given by

E=\frac{V}{d}=\frac{200 V}{5\cdot 10^{-4} m}=4\cdot 10^5 V/m

and the energy density of the electric field is given by

u=\frac{1}{2}\epsilon_0 E^2

and using

E=4\cdot 10^5 V/m, we find

u=\frac{1}{2}(8.85\cdot 10^{-12} F/m)(4\cdot 10^5 V/m)^2=0.71 J/m^3

How does Newton's third law of motion give a property of process​
elixir [45]

Answer:

Newton's third law explains the generation of thrust by a rocket engine. In a rocket engine, hot exhaust gas is produced through the combustion of a fuel with an oxidizer. The hot exhaust gas flows through the rocket nozzle and is accelerated to the rear of the rocket. In re-action, a thrusting force is produced on the engine mount.

Grassland is the most likely have the deepest layer of topsoil

Topsoil is the outermost layer of the soil that has the highest concentration of of organic matter and microorganism which is very important for plant's growth. Since grassland have a deep layers of topsoil, most of the farmers us it to grow their farm products
