<h2>Basic Research - Option B</h2>
Experimenting to determine the fundamental properties of x-rays would be an example of basic research. The experimental primary analysis tries to determine the laws of the events. The primary analysis is expected to know the stuff, its sort, its characteristics and its performance. It examines to get the speculation. To obtain wherewith the stuff performance yet not how to practice these forms for a firm determination.
The research of the characteristics of the particle to explain whatever it is, how it combines with other atoms, how it determines the characteristics of the material are some instances of primary analysis. For example examining to ascertain the basic features of x-rays. Spencer's research on WWII radar technology that drove to the discovery of the microwave furnace.
Edison's research and application of other scientists task is to create the light bulb, and Morrison and Franscioni's research was made to build the Frisbee models of applied research science.
Florence Griffith-Joyner recorded a time 10.61 seconds (wind reading +1.2) in the final at the 1988 U.S. Olympic Trials the wind reading for this race is not in doubt, and the performance should be the official IAAF women's 100-m world record
Answer:
<u>The answer is the third option.</u>
Explanation:
The electrostatic force, Coulomb's force, is a force that depends on the inverse of the square distance, it is a non-contact force.
On the other hand, stretched spring is a contact force, it needs a contact external force.
Therefore, <u>the answer is the third option.</u>
I hope it helps you!

Answer:
a. 
b. 
c. 
Explanation:
Given,
*initial velocity of the ball = 
*angle of projection = \theta_i
Horizontal component of the initial velocity of the ball = 
vertical initial component of the initial velocity of the ball = 
part a
From the kinematics,
In the y-direction motion,
total vertical displacement of the ball during the whole motion is zero.
Ball is moving under the gravitational acceleration, therefore the acceleration of the ball = -g, because gravitational acceleration always acts in the downward direction,
Let t be the time of flight of the whole motion,
part b.
At the peak of the path of the ball, the vertical component of the velocity of the ball becomes zero, only horizontal component of the velocity acts on the ball is equal to =
part c.
Initial vertical component of the velocity of the ball =
