Explanation:
(a) Formula to calculate the density is as follows.
= 
= 
Now, calculate the charge as follows.
= 
= 
C
or, = 101.06 nC
(b) For r = 6.50 cm, the value of charge will be calculated as follows.
= 
= 7.454 
Answer:
D) The negatively charged electrons
Electricity passes through metallic conductors as a flow of negatively charged electrons. The electrons are free to move from one atom to another. We call them a sea of delocalised electrons. Current was originally defined as the flow of charges from positive to negative. Please give me the brainliest answer?
:) Hoped this helped!!! Have a good day!!! <3
Answer: Black hole.
Explanation:
As the massive star "compacts" under its own gravity, it triggers a massive supernova, after this point the remains of the star can become a neutron star, which is a very compact star made primarily, as the name says, of neutrons. The other possibility is a black hole, which is a finite region of space wherein it's interior there is a big concentration of mass, which creates a gravitational field strong enough that there is no particle that can escape it.
its B 0.225kPa using the formula p=f/A then change the pascals into kpa
