What happens to the electric potential energy of a negatively charged ion as it moves through the water from the negative probe
Nataly [62]

Answer:

Decreases.

Explanation:

Electric potential energy is the potential energy which is associated with the configuration of points charge in a system and it is the result of conservative coulomb force.

When the negatively charge ion is at the position of the negative probe than its potential energy is positive when it is move towards the positive probe it's potential energy becomes negative due to the negative ion.

Therefore, potential energy is decreases when negative charge ion moves through the water from negative probe to positive probe.

An alpha particle (charge = +2.0e) is sent at high speed toward a gold nucleus (charge = +79e). What is the electric force actin
umka2103 [35]

Answer:

F = 91.27 N

Explanation:

Parameters given:

Charge of alpha particle, q = +2.0e = 2.0 * 1.60217662 * 10^{-19} = 3.204 * 10^{-19} C

Charge of gold nucleus, Q = +79e = 79 * 1.60217662 * 10^{-19} = 1.266 * 10^{-17} C

Distance between the alpha particle and gold nucleus, r = 2.0 * 10^{-14} m

Electric force is given as:

F = \frac{kqQ}{r^2}

where k = Coulomb's constant

Therefore:

F = \frac{9 * 10^9 * 3.204 * 10^{-19} * 1.266 * 10^{-17}}{(2.0 * 10^{-14})^2} \\\\\\F = 91.27 N

The electric force acting on the alpha particle when the alpha particle is 2.0 * 10^{-14} m from the gold nucleus is 91.27 N.

An object in motion will have a speed which is a scaler , or ( blank ) which is a vector .
mylen [45]

Answer:

Velocity

Explanation:

Objects in motion usually have a speed which is scalar or velocity which is a vector.

A scalar quantity is one with magnitude but has no directional attribute.

A vector quantity is one with both magnitude and directional attribute.

Speed is a scalar quantity that describes the magnitude of motion a body accrues.

Velocity is a vector quantity that describes both the magnitude of motion and the direction of motion in a body.
