Answer:
Explanation:
they trade velocities... so the Satellite now is going 5000 m/s
Answer:
Explanation:
We are given that
Number of turns,N=500
Radius,r=0.04 m
Length of solenoid,L=40 cm=
1 m=100 cm
Current,I=12 A
We have to find the magnitude of magnetic field near the center of the solenoid.
Number of turns per unit length,n=
Magnetic field near the center of the solenoid,B=
Where
It should be S since S stands for students. Giving the team with more members the upper hand. Hope this helps.
Answer:
a) There are electrons in a liter of water.
b) The net charge is -53601707,1 C
Explanation:
a) To find out how many electrons are in a liter of water (equivalent to 1000 grams of water), we have to find out how many molecules of water there are and then multiply it by 10 (e- per molecule).
We can find out how many molecules are by finding the number of moles and then multiplying it by Avogadro's number (number of elements per mol):
b) As all electrons have the same charge, in order to find the net charge of those electrons we have to multiply the charge of a single electron by the number of electrons:
An important clarification is that while the net charge may seem huge, water as a whole is a neutral medium, because there are as many protons as there are electrons, and as they have the same charge, the net charge of water is 0.
