Answer:
600 mC
Explanation:
The charge of an electron is 1.6 x 10-19C so for a current with 10 mA, the charge going to screen in one second is 10 mC
so number of electrons, n = (10 x 10-3)/(1.6 x 10-19) = 6.25 x 1016 so in a minute the charge is 10 * 60 = 600 mC
Answer:
The difference between the Electrolyte and Non-Electrolyte are given in the explanation part.
Explanation:
- ELECTROLYTES are salts or molecules which ionize in solution fully.
- Electrolyte solutions thus conduct electricity readily.
whereas
- NON ELECTROLYTES in water do not dissociate from ions,
- non-electrolyte solutions do not conduct electricity.
For the 5.0Kg block with the force of 15 Newton, the coefficient of static friction (μ) comes out to be 0.306. Applying the formula F = μmg.
Static friction acts on stationary body/body at rest. Let μ be the coefficient of static friction between the block and the horizontal floor.
Using the formula: F = μmg
Where,
F = Force , m= mass of the block and g = gravity.
and values of: m= 5.0Kg, F= 15.0N, g= 9.8m/s²
We can get: μ = F/(mg)
μ = 15/49
μ =0.306
Therefore, coefficient of static friction (μ) = 0.306.

The answer to the question is sound
The pressure of the atmosphere, when a barometer reads 780 mm Hg. Mercury which a density of 1.36 x 10^4 kg /m^3 is B 1.1 x 10^5 N/m^2
This problem can be solved using the formula below
P = dgh................. Equation 1
Where P = Pressure of the atmosphere, d = density of the mercury, h = height of the mercury, g = acceleration due to gravity.
From the question,
Given: d = 1.36×10⁴ kg/m³, h = 780 mm = 0.78 m,
Constant: g = 10 m/s²
Substitute these values into equation 1
P = (1.36×10⁴)(10)(0.78)
P = 10.608×10⁴ N/m²
P ≈ 1.1×10⁵ N/m²
Hence the right answer is B. 1.1×10⁵ N/m²
