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:
Earth's atmosphere is a mixture of nitrogen (79%), oxygen (20%), and a small fraction of carbon dioxide, water vapours and other gases. However, the atmospheres on Venus and Mars mainly consist of carbon dioxide.
Explanation:
Answer:
they are eletric and magnetic
Explanation:
Answer:
0.20 A
Explanation:
The current in the wire is given by Ohm's law:
where
I is the current
V is the voltage
R is the resistance
In this problem,
V = 3.0 V is the voltage
is the resistance
Substituting into the formula,
Answer:
-200 N
Explanation:
The cabinet moves at constant velocity, so that means there's no acceleration.
Applying Newton's second law to the cabinet:
∑F = ma
F + 200 = 0
F = -200
The friction force is 200 N in the opposite direction.
