Answer:
I believe it's called qualitative
Explanation:
Answer:
Explanation:
Let the total force be F
The force that produces motion in the x direction is given as, 
Let the frictional force be given as:
Thus, the net force is given as:
Some ice has more salt then the other causing it to float up
Answer: A
The diffusion time through the edge is double the diffusion time through the center.
Explanation:
Only the diffusion coefficient, thickness, surface area, distance affects the time it takes a gas such as oxygen to diffuse a given in a medium. The Diffusion time increases with the square of diffusion distance Also, the Increased surface area increases the rate of diffusion or the diffusion time, whereas a thicker membrane reduces the rate of diffusion or time it takes the gas to be permeable. Also, The greater the distance that a substance must travel, the slower the rate of diffusion The diffusion coefficient determines the time it takes a gas to diffuse. Also the Diffusion time is inversely proportional to the diffusion coefficient.
Now, If the edge of a contact lens is double the thickness of the central portion of the lens, then it will take more time for the gas to diffuse through the thicker portion. since its edge is double the central position, then the diffusion time will also be doubled. So Option A is the best answer-
The diffusion time through the edge is double the diffusion time through the center.
Answer:
There are two popular forms of softball, distinguished by the type of pitch.
Explanation:
Softball refers to a kind of sports that is similar to baseball in terms of game play but softball is played with a larger ball. The game of softball was first introduced as an indoor game in Chicago, Illinois, United States of America in the year 1887. Also, the field for playing softball is relatively smaller than that of baseball and as such its game play is quite faster.
Some of the kits and paraphernalia used for playing softball are base, bat, softball, gloves, jerseys etc.
There are two (2) main types of softball game and these are;
I. Fast-pitch softball.
II. Slow-pitch softball.
Hence, the true statement regarding softball is that, there are two popular forms of softball, distinguished by the type of pitch.
