When a potassium atom forms an ion, it loses one electron. What is the electrical charge of the potassium ion?

Physics
1 answer:
fomenos3 years ago
6 0
The correct answer is answer choice C. +1. Since electrons have negative charges, losing one electron will cause the atom to have a positive charge of 1. This charge comes from the protons, which, until one electron was lost, balanced out the negative charge of the electrons and caused the atom to be neutral.

Mass of 23.94kg and volume 2.10 cubic centimeters. Calculate the density of the copper wire in si units (ų/mm cubic)
Kamila [148]

Answer:

Density = 1.14 kg/mm³

Explanation:

Given the following data;

Volume = 2.10 cm³ to mm = 2.10 * 10 = 21 mm³

Mass = 23.94kg

To find the density;

Density can be defined as mass all over the volume of an object.

Simply stated, density is mass per unit volume of an object.

Mathematically, density is given by the equation;

Density = \frac{mass}{volume}

Substituting into the equation, we have;

Density = \frac{23.94}{21}

Density = 1.14 kg/mm³

A bullet is shot from a rifle with a velocity of 720.0 m/s what time is required for the bullet to strike a target 324.0m to the
Basile [38]

The bullet will strike the target placed in 324.0 m in the East in 0.45 seconds.

<u>Explanation:</u>

As we all know the epic relation between distance, speed and time; we cam easily estimate the time in which an object can reach to the destination or target.

As here in this case, we know the distance of the target and the velocity of a bullet exerted from a rifle given as follows,

Distance of the Target from the rifle edge = 324.0 m

Velocity of bullet exerted from the rifle = 720 m/s

Since we know that,

      \text {velocity}=\frac{\text {distance}}{\text {time}}

or

       \text {Time}=\frac{\text {distance}}{\text {velocity}}

We can simply implement all the values in the formula and get the results i.e the time required by the bullet to hit the target. Since both the values are in S.I units measures, we don't need to change or convert any of them. Hence,

       \text { Time }=\frac{324}{75}=0.45 \text { seconds }

Therefore, the bullet will hit the target in 0.45 seconds.
