Answer : The excess of electrons on the penny are, 
electrons
Solution : Given,
Total charge = 
Charge on electron = 
Formula used :
Now put all the given values in this formula, we get the excess of electrons present on the penny.
Therefore, the excess of electrons on the penny are, electrons
Answer:
In my opinion, I think we do change when people come to our lives because the way we feel around people makes us feel a certain way around all people in our lives in a good way. They can change our lives by being there and helping us physically and mentally. We do have the choice to follow what someone is trying to change us. Example if we have a problem like addiction, we can choose to get help from anyone or choose not to. Traumas can affect us, but we need to seek help to not fear those problems anymore, thats why people who care about us really want us to change our way of health, addictions, and mental health. For me, as a child my dad was deported because he got a dui and decided for as punishment to be deported or to have a life sentence in the U.S. My mom suffered addiction to drugs and alcohol. I lived with my grandparents for almost my whole childhood untill the age of 9. Then my aunt got engaged and my new uncle decided to take us in because DC.S foound out that me and my other sibling weren't in school at all. Like we never attended school. So we were going to be seperated and taken for adoption untill my uncle had the heart to adopt us and here I am today. He gave us a better life because I finally experienced school,clothes, food, and a safer place to live. All the things I went through even abuse. He changed my life and we changed his. He cares about us, we helped him quit drinking, and that impacts him a lot to open up his heart and quit drinking.

Answer:
2 x 10^14 N/Cs
Explanation:
radius, r = 3 cm
Area , A = 3.14 x 3 x 3 = 28.26 cm^2 = 28.26 x 10^-4 m^2
d = 1.1 mm = 1.1 x 10^-3 m
i = 5 A
Let time be t and electric field strength is E.
Charge, q = i x t = 5 t
q = C V
q = C x E x d
E/t = 2 x 10^14 N/Cs
Answer:
voltage= 17.88volts
current= 0.04 amps
Explanation:
Step one:
given data
resistance R=400 ohms
Power P= 0.8W
a. What is the maximum voltage that can be applied across this resistor without damaging it?
the expression relating power and voltage is
P=V^2/R
substituting we have
0.8=V^2/400
V^2=0.8*400
V^2=320
V=√320
V=17.88 volts
the maximum voltage is 17.88volts
b.What is the maximum current it can draw?
we know that from Ohm' law
V=IR
17.88=I*400
I=17.88/400
I=0.04amps
Answer:
Yes
Explanation:
n1 sinθ1 = n2 sinθ2, where θ1 and θ2 are the angles of incidence and refraction.
changing D between them will not affect dependence
