Answer: The height of the fluid rise is 0.01m
Explanation:
Using the equation
h = (2TcosѲ )/rpg
h= height of the fluid rise
diameter of the tube =3mm
radius of the tube= 3/2 =1.5mm=0.0015
T= surface tension = 600mN/m=0.6N/m
Ѳ = contact angle = 
C
p= density =3.7g/cm3= 3700kg/m3
g= acceleration due to gravity =9.8m/s2
h = ( 2*0.6*0.5)/(0.0015*3700*9.8)
h = 0.6/54.39
h= 0.01m
Therefore,the height of the fluid rise is 0.01m
When object is moving in circular path then if suddenly its force reduced to zero then it will move to straight line
This is defined by Newton's First Law
So as per first law of Newton we can say
When there is no net force on an object then it will continue its state of motion in its original state without any change in it.
This is also known as law of inertia
so correct answer will be
Newton's 1st law
Answer:
the branch of science concerned with the nature and properties of matter and energy. The subject matter of physics, distinguished from that of chemistry and biology, includes mechanics, heat, light and other radiation, sound, electricity, magnetism, and the structure of atoms.
physics, science that deals with the structure of matter and the interactions between the fundamental constituents of the observable universe. In the broadest sense, physics (from the Greek physikos) is concerned with all aspects of nature on both the macroscopic and submicroscopic levels.
The average speed of the tennis ball is 3 m/s.
<h3 /><h3 /><h3>What is average speed?</h3>
Average speed can be defined as the ratio of the total distance to the total time covered by the body. The S.I unit of average speed is m/s.
To calculate the formula below.
Formula:
- S = d/t............... Equation 1
Where:
- S = Average speed of the ball
- d = Total Distance
- t = Total time.
From the question,
Given:
- d = 18 meters
- t = 6 seconds
Substitute these values into equation 1
Hence, The average speed of the tennis ball is 3 m/s.
