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:
the speed of a jet plane = v = 12 m/s
Explanation:
jet plane that travels 48 meters East in 4 seconds?
<u>use the velocity as distance over time formula = v = d / t</u>
where:
t = 4 sec
d = 48 m
plugin values into the formula
v = <u> 48 m </u>
4 sec
v = 12 m/s
therefore,
the speed of a jet plane = v = 12 m/s
<span>When designing an experiment a benefit of larger sample sizes would be more representative data. This larger sample size would lead to perfect result. The correct option among all the options that are given in the question is the second option or option "B". I hope the answer comes to your help.</span>
The relationship if time according to the speed of light can be represented using Lorentz' time-dilation equation:
T = To / sqrt( 1 - (v^2/c^2) )
Where:
T = new time = ?
To = original time = 1 minute
v = velocity = 0.6c
c = speed of light
Substituting the given values:
T = 1 / sqrt( 1 - (0.6c^2/c^2) <span>)</span>
T = 1 / sqrt( 1 - (0.6^2) <span>)
</span>T = 1.25
Therefore, the alarm clock would ring for 1.25 minutes.
Answer:
C) They walked in one direction, then they were still, then they walked in the opposite direction.
Explanation:
John and Caroline go out for a walk one day. This graph represents their distance from home.c According to the graph they walked with almost same in both the direction.
First they walked in one direction and travel 30 meter in same direction then they were still for some time. Then they walked in the opposite direction for 30 meter. They walked in both the direction with approximately equal speed.
Thus, Option C is correct.
