Answer:
The linear charge density is 5.19 X 10⁻⁶ C/m
Explanation:
The potential difference between two cylinders, is given as
V = (λ/2πε)ln(b/a)
where;
λ is the line charge density on the power line.
b is the distance between the power line = 1 m
a is the radius of the wire = 1.5 cm = 0.015 m
ε is the permittivity of free space = 8.9 X 10⁻¹² C
V*2πε = λ* ln(b/a)
3900 *(2π*8.9 x10⁻¹²)= λ *ln(1/0.015)
2.1812 X 10⁻⁷ = 4.1997* λ
λ = 5.19 X 10⁻⁶ C/m
Therefore, the linear charge density is 5.19 X 10⁻⁶ C/m
Answer:
in the nucleus of the atom
Explanation:
a p 3 x
Answer:
1.25 m/s²
Explanation:
Average acceleration is the change in velocity over change in time.
a = Δv / Δt
a = (5 m/s − 0 m/s) / 4 s
a = 1.25 m/s²
Answer:
The blender was running for 35 seconds.
Explanation:
Given:
Power of the blender is, 
Work done by the blender is, 
We know that, power is defined as the rate at which work is done by the body.
Here, we are given the power and work done and we are asked to find time taken.
Let the time of running of the blender be 't' seconds.
So, the power of the blender is given as:
Rewriting the above in terms of 't', we have
Plug in the given values and solve for 't'. This gives,
Therefore, the blender was running for 35 seconds.
Answer:
When you burned the skewer tip coated with sodium chloride, you should have seen that the flame was pure yellow-orange (without any blue). This is because when the metal sodium is burned, it makes intense yellow-orange light. ... This is because when the metal copper is burned, it makes bluish-green light.
hope this helps
