In the early twentieth century, _______ redefined psychology as "the science of observable behavior."

The Earth's electric field creates a potential that increases 100 V for every meter of altitude. If an object of charge 4.5 mC a

castortr0y [4]

Answer:

The final kinetic energy is $K = 1.1 \ J$

Explanation:

From the question we are told that

The electric field is $E = 100 \ V/m$

The charge on the object is $q = 4.5 mC = 4.5 *10^{-3} \ C$

The mass of the object is $m_o = 68 \ g = 0.68 \ kg$

The distance moved by the object is $d = 1.0 \ m$

The workdone on the object by the fields is mathematically represented as

$W = [qE + mg]d$

Now this workdone is equivalent to the final kinetic energy so

$K = W = [qE + mg]d$

substituting values

$K = W = [4.5*10^{-3 } *100 + 0.68 * 9.8]* 1$

$K = 1.1 \ J$

The weight of an object is the force generated by Earth's gravity accelerating the object's _________. distance mass time destin

julsineya [31]

The weight of an object is the force of gravity between Earth's
mass and the object's mass.

The forces of gravity always come in equal, opposite pairs.
The Earth's weight on the object is the same as the object's
weight on the Earth, and when the object falls to Earth, Earth
falls to the object.

A spherical conductor is inside a uniform electric field with a magnitude of 1000 N/C to the right. What is the magnitude and di

Lyrx [107]

Answer:

1.-E=1000N/C to the LEFT

2.-The electric field inside a conductor in electrostatic state is always zero (conductor proprieties).

3.-The voltmeter read 0V as differential voltage between two points from the conductor

Explanation:

1.The electric field inside the conductor must be zero (conductor proprieties). Then the charges create a electric field equal an opposite to the external electric field. In other words E=1000N/C to the LEFT

2. The electric field inside a conductor in electrostatic state is always zero. As shown in the figure the electric field induced by the charges in the sphere surface cancelled the EXTERN electric field.

3.If the Electric field inside the conductor is zero, that means that the Voltage in the hole conductor is constant (conductor proprieties). In other words the the voltmeter read 0v as differential voltage between two points from the conductor.
