The behavior of an object that has been charged is dependent upon whether the object is made of a conductive or a nonconductive material. Conductors are materials that permit electrons to flow freely from particle to particle. An object made of a conducting material will permit charge to be transferred across the entire surface of the object. If charge is transferred to the object at a given location, that charge is quickly distributed across the entire surface of the object. The distribution of charge is the result of electron movement. Since conductors allow for electrons to be transported from particle to particle, a charged object will always distribute its charge until the overall repulsive forces between excess electrons is minimized. If a charged conductor is touched to another object, the conductor can even transfer its charge to that object. The transfer of charge between objects occurs more readily if the second object is made of a conducting material. Conductors allow for charge transfer through the free movement of electrons.

An arctic weather balloon is filled with 4.96 L of helium gas inside a prep shed. The temperature inside the shed is 6. °C. The
Virty [35]

The new volume of the balloon : V₂ = 4.89 L

<h3>Further explanation</h3>

Given

V₁ = 4.96 L

T₁ = 6 + 273 = 279 K

T₂ = 2 + 273 = 275 K

Required

The new volume

Solution

Charles's Law  

When the gas pressure is kept constant, the gas volume is proportional to the temperature  

\tt \dfrac{V_1}{T_1}=\dfrac{V_2}{T_2}

Input the value :

V₂=V₁.T₂/T₁

V₂ = 4.96 x 275 / 279

V₂ = 4.89 L

The mass of an object Is 45 kilograms. It’s weight on earth is—— newtons, and it’s weight on the moon is ——newtons. Gravitationa
Lina20 [59]

Answer:

The weight of the object on earth =441N

Weight of the object on moon = 72N

Explanation:

Weight of a body is the product of its mass and acceleration due to gravity. Acceleration due to gravity varies between planetary bodies. The acceleration due to gravity on earth is 9.8 m/s² while on moon is 1.6m/s² and it goes different for others too.

Weight = Mass * acceleration due to gravity

Weight(e) = weight on earth

Weight (m) = weight on moon

Weight(e) = 45 * 9.8 = 441N

Weight (m) = 45 * 1.6 = 72N

Weight of a body is measured in a unit called Newton(N)

A positive charge is placed at rest at the center of a region of space in which there is a uniform, three-dimensional electric f
Vladimir [108]

Answer:

Ans- It will decrease as the charge travels towards the electrical field.

Explanation:

Ans- It will decrease as the charge travels towards the electrical field.

As we have learn, F= qE i.e. the electrical field will exert a force on the positively charged in the direction of the electrical field, this will accelerate the positive charge resulting in the conversion of potential energy into kinetic energy.

How many grams of NH3 can be produced from 2.27mol of N2 and excess H2.
Diano4ka-milaya [45]
The reaction formula of this is N2 + 3H2 = 2NH3. So the ratio of mol number of N2 and NH3 is 1:2. The mol number of NH3 is 2.27*2=4.54 mol. So the mass is 4.54*17=77.18 g.
