Answer:
I think D. maybe C
Explanation:
newtons is force of gravity and grams can be weight or mass in the metric system
Answer:
(a) 6.8 x 10^5 Nm^2/C
(b) 1.47 x 10^5 Nm^2/C
(c) 5.3 x 10^5 Nm^2/C
Explanation:
According to the Gauss's theorem
Electric flux = Charge enclosed / ∈0
(a) Charge enclosed = 6 x 10^-6 C
So, Electric flux = (6 x 10^-6) / (8.854 x 10^-12) = 6.8 x 10^5 Nm^2/C
(b) Charge enclosed = -1.3 x 10^-6 C
So, Electric flux = (1.3 x 10^-6) / (8.854 x 10^-12) = 1.47 x 10^5 Nm^2/C
(c) Charge enclosed = 6 x 10^-6 + (-1.3 x 10^-6) = 4.7 x 10^-6 C
So, Electric flux = (4.7 x 10^-6) / (8.854 x 10^-12) = 5.3 x 10^5 Nm^2/C
The coefficient of kinetic friction (μ) between the block and the table is 0.4.

What is kinetic friction?</h3>
This sis the frictional force between an object in motion with the surface in contact.
μN = ff
where;
- N is normal reaction due to weight of the block
- ff is frictional force
- μ is coefficient of friction
μ = ff/N
μ = 8/20
μ = 0.4
Thus, the coefficient of kinetic friction (μ) between the block and the table is 0.4.

There are many things you have to do but a quick run down would be keep notes, share their information, take many tests, always be safe when testing something, etc.
