Answer: V = 3.4 L

Explanation: Use Boyle's Law to find the new volume. P1V1 = P2V2, derive for V2, then the formula will be V2= P1V1 / P2

V2 = 2.5 atm ( 4.5 L ) / 3.3 atm

= 3.4 L

Answer:3.40L

Explanation:

p1v1=p2v2

P1=2.5atm

V1= 4.5L

P2=3.3atm

V2=?

P1V1/P2=V2

V2=2.5*4.5/3.3

V2= 11.25/3.3

V2=3.40L

The form of energy given off by the vibrating strings of the violin is? A. Electrical Energy B. Potential Energy C. Radiant Ener
S_A_V [24]

Answer:

D . Sound energy

Explanation:

When the strings of a violin vibrate it produces sound which is sound energy. Due to the vibration of the strings the air present near the strings also vibrate in resonance with the strings. This compreesion and decompression's produced in the air is nothing but the sound. So the form of energy given off by the vibrating strings of the violin is Sound energy.

How to describe electric current as the flow of electrons
givi [52]
An electric current is a flow of electric charge. In electric circuits this charge is often carried by moving electrons in a wire. It can also be carried by ions in an electrolyte, or by both ions and electrons such as in an ionised gas (plasma).

La) What is meant by the term Basic Quantities.​
castortr0y [4]

Answer:

A basic quantity is basically the physical quantity that can not be defined in terms of other quantities.

Explanation:

A basic quantity is basically the physical quantity that can not be defined in terms of other quantities.

Some of the names of the basic quantities include:

  1. Mass, denoted by the symbol 'm', with S.I. unit 'kg'
  2. Length, denoted by symbol 'l', with S.I. unit 'm'
  3. Time, denoted by symbol 't', with S.I. unit 's'
  4. Current, denoted by 'I', with S.I. unit 's' 'A'
  5. Temperature, denoted by 'T', with S.I. unit 'K'
  6. Amount of substance, denoted by 'n', with S.I. unit 'mol'
  7. Luminous Intensity, denoted by 'Iv', with S.I. unit 'cd'

  • A basic quantity is chosen arbitrarily.

<span>In order to calculate an average, we should sum all numbers and divide them by quantity. Let’s work with qualifications first. Let’s say you got a 10 in 1 exam, then an 8 in 2 exams and a 4 in 2 exams. Your average will be: = (10*1+8*2+4*2) / 5 = 6.8 If 6 is the minimum, you will pass. There is another way to calculate this average: applying distributive property. = 10*1/5+8*2/5+4*2/5 = 6.8 Remember you can convert the fractions into equivalent fractions: 1/5 = 20/100; 2/5 = 40/100 = 10*20/100+8*20/100+4*20/100 = 6.8 We actually don’t have the number of atoms of each mass… we have the percentage instead! So we need to learn this last method for atoms. Let’s go back to our atoms problem: 73.71 % of atoms have a mass of 27.98 u 14.93 % of atoms have a mass of 28.98 u 11.36 % of atoms have a mass of 29.97 u So let’s put that in the formula: Average mass = 27.98 u*73.71 /100 + 28.98 u*14.93 /100 + 29.97u*11.36 /100 So what you have to know is that a percentage can be converted into a fraction, and you should work that fraction in order to find the average. We can make the calculus shorter putting 100 as the common denominator: Average mass = (27.98 u*73.71 + 28.98 u*14.93 + 29.97u*11.36)/100 So actually we are taking the percentage as if it was the quantity, and 100 as if it was the total (the total of all percentages is always 100). Maybe we don’t have 100 atoms, but it will be the same proportion anyway, whatever number we have! And here it is the result: Average mass = 28,36u </span>

4. A motorist travels 406 km during a 9.0 hr period. What was the average speed in km/hr and m/s?
user100 [1]

Answer:

45.11 kmph and 12.530 m/s

Explanation:

Average speed = Total distance travelled / Total time taken

406/9 gives the answer in kilometers

And we convert it to m/s by multiplying it with 1000/3600
