How much work will be done in making a soap bubble of diameter 2cm?

Complete step by step answer: Given: The diameter of the soap bubble is, \[d = 2.0\;{\rm{cm}}\]. Here, r denoted the radius of the soap bubble and its value is, \[r = d/2\]. Therefore, the required work to make the soap bubble is \[7.54 \times {10^{ – 5}}\;{\rm{J}}\].

How much work will be done in increasing the diameter of a soap bubble from 2 Centimetre to 5 cm?

How much work will be done in increasing the diameter of a soap bubble from 2cm to 5cm? Surface tension solution is 3.0xx10^(-2)N//m. =3.96×104J.

How much work will be done in increasing the diameter of a soap bubble from 2 cm to 5 cm surface tension of soap is 3/10 2 NM 1?

Complete step by step answer Let $r$ be the initial radius of the bubble in the process of enlargement and let it increase to a radius of $r + dr$(considering the soap bubbles to be spherical in shape). So, the net work done to increase the diameter of the soap bubble from $2cm$to $5cm$ is $3.96 \times {10^{ – 4}}J$.

How much work will be done in making a soap bubble of diameter?

Answer: Work Done (W) in Making A Soap Bubble is 7.54 x 10⁻⁴ Joules.

How much work should be done in constructing a soap bubble of radius 5 cm?

(Ans : 15700 erg)

How much work will be done in large in the surface area of a soap bubble by 1.0 cm square?

How much work will be done in enlarging the surface area of a soap bubble by 1.0 cm2 Ans. 6.0 x 10-6 J.

What is the work done in blowing a soap bubble from a radius of 3 cm to 5 cm?

2.2 × 10−3.

What is the surface area of a soap bubble?

Surface area of soap bubble is 1. 3×10−4m2 .

What is the work done in blowing a soap bubble?

The work done in blowing a soap bubble of radius R is W. The work done in blowing a bubble of radius 2R of the same soap solution is 4W. where, T is the surface tension and A is the area of soap bubble.

What should be diameter of a soap bubble in order that the excess pressure inside it is 51.2nm ²?

What should be the diameter of a soap bubble, in order that the excess pressure inside it is 51.2 N/m? N/m) (S.T. of soap solution = 3.2 x 10 (Ans: 5 mm)

What is the surface area of soap bubble?

Surface area of soap bubble is 1. 3×10−4m2 . The work done to double the surface area will be:[surface tension(T) for solution: 3×10−3N/m]

What is the surface tension of a soap bubble?

The surface tension is numerically equal to the surface energy per unit area. When a soap bubble is formed, the area involved is 4 π r 2 each for the inner and outer surface of the bubble, assuming that the thickness of the bubble can be ignored. ⇒ The work done is, W = 2.

How do you calculate the surface area of a 2-cm bubble?

So work out the area of 2 cm bubble in square metres, same for the 5 cm bubble, subtract them to find the change in surface area, then multiply by 0.06 8 clever moves when you have $1,000 in the bank. We’ve put together a list of 8 money apps to get you on the path towards a bright financial future.

What happens when a soap bubble has a negative charge?

In an uncharged soap bubble, there is an equilibrium between positive and negative charges. When there are like charges on the surface of the bubble (negative charge in this case), the equilibrium is lost. To attain this lost equilibrium, the charges start repelling each other.
