As you approach the surface of the sphere very closely, the electric field should resemble more and more the electric field from an infinite plane of charge.
If you check Gauss's law (recalling that the field in the conductor is zero) you will see that if the surface charge density is σ=Q/4πR2, then indeed the field at the surface is σ/ϵ0 as in the infinite charge of plane case.
Such a field is constant, the field lines are parallel and non-diverging, and the infinities associated with the field due to point charge do not arise.

Explanation:
Calculating acceleration is complicated if both speed and direction are changing or if you want to know acceleration at any given instant in time. However, it’s relatively easy to calculate average acceleration over a period of time when only speed is changing. Then acceleration is the change in velocity (represented by Δv) divided by the change in time (represented by Δt):
acceleration=ΔvΔt
The upward force of the chain on the diamond would be the tension in the chain, and this tension would have to support the weight of the 45g that hangs from the chain.
mass = 45 g = 45/1000 kg = 0.045kg
Weight = mg = 0.045 * 10 ≈ 0.45N, g ≈ 10 m/s²
<span>So the upward force is ≈ </span><span>0.45N. </span>
Answer:
Monitoring reader comments and engagements, mini research about the demographics of previous edition, an online survey
Explanation:
The more she understands the background and need of her audience, the better her speech and coherence will be .
Some ways to discover her audience are:
1. Ask the organizers or do a mini research about the demographics of the audiences that are at the previous edition of the annual fund-raiser. Knowing the demographics such as gender, age group, level of education, language,culture etc. will allow her to Know about the audience's interest ad common grounds.
2. Monitoring of comments and engagements about the program can give her incite about the audience
3. A survey can be carried out if the audience are accessible.
