For the answer to the question above asking to c<span>alculate the work done to stretch an elastic string by 40cm if a force of 10N produces an extension of 4cm in it. The needed force for this is 100N of work</span>
Answer:
3.3×10⁻⁹ kg/s
Explanation:
There are two forces on the particle: weight force pulling down and drag force pushing up. At terminal velocity, the speed is constant, so the acceleration is zero.
∑F = ma
bv − mg = 0
b = mg / v
b = (10⁻¹³ kg) (9.8 m/s²) / (3×10⁻⁴ m/s)
b = 3.3×10⁻⁹ kg/s
let the moles of chlorine-35 is n1 and chlorine-37 is n2
now we will use the formula of average atomic mass
here let say
so here since ratio of moles of chlorine 35 and chlorine 37 is more than 1 so chlorine 35 is more in the proportion in this mixture so <em>there is most chlorine atom consist of 18 neutrons</em>
Answer:
The gram is the basic unit of measurement
Explanation:
You use it to weigh small items such as sugar, flour, coffee, and other items that are similar.
If you want to measure in grams using a scale is the most accurate solution.
