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.
Answer:
11250 N/C
Direction: 0 deg counterclockwise from positive x-axis
Explanation:
= magnitude of charge on each particle = 5 μC = 5 x 10⁻⁶ C
= distance of each particle from center of circle = 2 m
= Magnitude of electric field at the center by each particle
Magnitude of electric field at the center by each particle is given as
inserting the values
From the diagram , we see that being equal and opposite, the electric fields due to charge q₁ and q₃ cancel out.
So net electric field at center is only due to charge q₂ direction towards positive x-direction
So
= Resultant electric field = 11250 N/C
Direction: 0 deg counterclockwise from positive x-axis
Answer:
B
Explanation:
Look for the one with an x coordinate of two .... answer B
the first bump car will move
Explanation:
this is because as long as the other bumper car is coming with force, it mass changes and then , it is able to push the other one
Answer:
the pressure fluctuation is LONGITUDINAL
Explanation:
Sound waves are an oscillating movement of air particles, this can be analyzed in two different, but equivalent ways, as an air oscillation and with a pressure wave due to these oscillations.
The expression for the wave is
ΔP = Δo sin (kx - wt)
Therefore, the pressure variation is in the same direction as the displacement variation, consequently the pressure fluctuation is LONGITUDINAL
