Which best describes a difference between electric current and static electricity?
2 answers:
Answer:
Electric current is continuous, and static electricity is not continuous.
Explanation:
Electric current is defined as rate of flow of charge which is given by
here we know that since this flow of charge is continuous so here electric current is continuous flow of charge.
Now for static electricity is instantaneous discharge of charge particles which are accumulated at a given point.
We can say it a part of a body is charged heavily then this heavy charge will instantaneously discharge to some other body of lower potential when it comes in contact with it.
So it is instantaneous current which flows for some fraction of time
so correct answer will be
Electric current is continuous, and static electricity is not continuous.

Answer:
mass = 0.18 [kg]
Explanation:
This is a classic problem where we can apply the definition of density which is equal to mass over volume.
mass = 0.18*1
mass = 0.18 [kg]
Complete question:
A light bulb emits light that travels uniformly in all directions. Detailed measurements show that at a distance of 56 m from the bulb, the amplitude of the electric field is 3.78 V/m. What is the average intensity of the light?
Answer:
The average intensity of the light is 0.02 W/m²
Explanation:
Given;
Amplitude of the electric field, E₀ = 3.78 V/m
The average intensity of the light is calculated as follows;
where;
is the average intensity of the light
c is speed of light = 3 x 10⁸ m/s
Therefore, the average intensity of the light is 0.02 W/m²
The flow rate is 17gtts/min.
<h3>What is the drug infusion rate?</h3>- The rate of infusion (or dosing rate) in pharmacokinetics refers to the ideal rate at which a drug should be supplied to achieve a steady state of a fixed dose that has been shown to be therapeutically effective. This rate is not only the rate at which a drug is administered.
- The infusion volume is divided into drops, which is known as a drip-rate. The Drip Rate formula is as follows: Volume (mL) times time (h) equals drip-rate. A patient must get 1,000 mL of intravenous fluids over the course of eight hours.
- Infusion rates of 3–4 mg/kg per minute are advised by manufacturers to reduce rate-related adverse effects. Usually, the infusion lasts for several hours. Although not advised, rates exceeding 5 mg/kg per hour may be tolerated by some patients.
- If no negative reactions occur, the rate may be increased in accordance with the table every 30 minutes up to a maximum rate of 3 ml/kg/hour (not to exceed 150 ml/hour).
To find the flow rate is 17gtts/min:
Therefore, The flow rate is 17gtts/min.
