Answer:
The amount of work that must be done to compress the gas 11 times less than its initial pressure is 909.091 J
Explanation:
The given variables are
Work done = 550 J
Volume change = V₂ - V₁ = -0.5V₁
Thus the product of pressure and volume change = work done by gas, thus
P × -0.5V₁ = 500 J
Hence -PV₁ = 1000 J
also P₁/V₁ = P₂/V₂ but V₂ = 0.5V₁ Therefore P₁/V₁ = P₂/0.5V₁ or P₁ = 2P₂
Also to compress the gas by a factor of 11 we have
P (V₂ - V₁) = P×(V₁/11 -V₁) = P(11V₁ - V₁)/11 = P×-10V₁/11 = -PV₁×10/11 = 1000 J ×10/11 = 909.091 J of work
The patient apply pressure to his side of the tube is 15 x 10⁴ N/m². The correct option is D.
<h3>What is pressure?</h3>
The pressure is the amount of force applied per unit area. It is represented as
Pressure p = Force/Area
Given is a doctor has a patient blow on one side of a U-shaped tube that is partially filled with water and has a ball floating on the other side. The ball rises with a force of 150 N. The cross section are of the tube is 0.001 m³
The pressure applied is
p = 150 /0.001
p = 15 x 10⁴ N/m²
Hence, the patient apply pressure to his side of the tube is 15 x 10⁴ N/m².

Answer:
Current in each branch will be 2.5 A
Explanation:
We have given that a circuit has three branch each has a resistance of 37.5 ohm
We have also given that a total current of 7.5 A is flows through the circuit
As we know that in parallel circuit total current is the sum of current flowing through each branch
As the resistances of each branch is same so current will also be same
As there is 3 branches in circuit so current in each branch will be
