Attraction (right?), so the + charge will try to go to the - charge. Force on + charge will be directed towards left. The magintude is Coulomb's law:
F = k * Q1*Q2/d^2, K = 9*10^9, Q1 = -4*10^(-6), Q2 = 6*10^(-6), and d = 0.45
-9*4*6*10^(-3)/0.45^2 = -1.0633 N, but check it (sign means attractive).
Some teachers prefer to say that magnitude is always positive, like in math, so 1.0633 N but then say attractive and directed to the left of the + charge, to make sure no one can complain you miss anything! Ask your teacher
We know, a = Δv / t
Here, a = 1.4 m/s²
Δv = 26-20 = 6 m/s
Substitute their values,
1.4 = 6/t
t = 6/1.4
t = 4.28 s
In short, Your Answer would be 4.28 seconds
Hope this helps!
Answer:
1Kilowatt =1000watts
Now
Energy =Power x time
We need our power in Kilowatt and Our time in hours
Given
Power = 1200Watt
Divide this by 1000... To get its value in Kilowatt
Power = 1.2kilowatt
Time=6min
Divide by 60 to get its value in hours
Time = 6/60hr = 0.1hrs
Energy = 1.2kilowatt x 0.1hrs
=0.12kilowatt hours
Answer:
The number of valence electrons increases to 8 or, the atom gives up loosely held valence electrons.
Explanation:
Please mark brainliest and have a great day!
-3 m/s
---------
per min
oh I think 8m/s to 3m/s to 0m/s
idk probably -0.08
