Explanation:
From the question we are told that:
Mass
Charge
Generally the equation for Total number of Atoms in Penny is mathematically given by
Since Number of electrons in a penny is
Therefore
The percentage of the atoms are ionized by this charging process is given as
Answer: 1.83Litres
Explanation:
From Charles Law, the volume of a given mass of gas is directly proportional to temperature,provided that pressure remains constant.
V1/T1 =V2/T2
V1 = 1.5L
T1 =25+273=298K
T2 = 90+273= 363K
V2= ?
1.5/298 = V2/363
V2 = 1.5 × 363 /298
V2 = 1.8L
Therefore at 90 degree Celsius, volume of the balloon is 1.8Litres
Answer: Yes.
Explaination: While some environmentalists choose to actively support each other (in other words, be environmental activists) a lot of environmentalist help keep the environment healthy without continuously or actively supporting the cause. For example, some people quietly take care of the environment while keeping to themselves, while others spread awareness, fund organizations, and help keep the environment clean by making an impact.
