An atom with an imbalance of electrons to protons is
alexdok [17]
<h2>Answer: Ion </h2>

An ion is an atom that is electrically charged by <u>gaining or losing one or more electrons. </u>

To understand it better:

An atom has a nucleus with electrons around it and has a neutral charge. When an electron is added or detached, this atom is electrically charged, that is, it ceases to have a neutral charge and becomes an <u>ion</u>.

In this sense, there are two types of ions:

-Anions: ions negatively charged, by the gain of electrons in the atom.

-Cations: ions positively charged, by the loss of electrons in the atom.

A penny is placed on a rotating turntable. Where on the turntable does the penny require the largest centripetal force to remain
Artyom0805 [142]

Answer:

m = mass of the penny

r = distance of the penny from the center of the turntable or axis of rotation

w = angular speed of rotation of turntable

F = centripetal force experienced by the penny

centripetal force "F" experienced by the penny of "m" at distance "r" from axis of rotation is given as

F = m r w²

in the above equation , mass of penny "m"  and angular speed "w" of the turntable is same at all places. hence the centripetal force directly depends on the radius .

hence greater the distance from center , greater will be the centripetal force to remain in place.  

So at the edge of the turntable , the penny experiences largest centripetal force to remain in place.

A car travels 2155.0m in 195.9s. What is the car's average speed?
inna [77]

Average speed of the car is 11 m/s

Explanation:

  • Speed is calculated by the rate of change of displacement.
  • It is given by the formula, Speed = Distance/Time
  • Here, distance = 2155 m and time = 195.9 s

Speed of the car = 2155/195.9 = 11 m/s
