Answer:
2.461
Explanation:
Let mass of Bonzo = m1
Mass of Ender =m2
When they push eachother from stationary position
Initial velocity of Bonzo = Vib=0 m/s
Final velocity of Bonzo = Vfb= 1.3 m/s
Initial velocity of Ender = Vie= 0 m/s
Final velocity of Ender = Vfe= -3.1 m/s
We know initial momentum = final momentum
==> m1Vib+m2Vie = m1Vfb+m2Vfe
==> 0+0= m1×1.3 +m2×(-3.1)
==> 1.3m1-3.1m2=0
==> 1.3 m1 = 3.2 m2
==> m1/m2 = 3.2/1.3
==> m1/m2 = 2.461
Answer:
Hurricane watch means hurricane conditions are expected in a specified area. As defined by National Oceanic and Atmospheric Administration (NOAA), it means that hurricane conditions (sustained winds of 74 mph or greater) are possible within your area. WHILE,
Hurricane warnings means hurricane conditions are expected in an area.
So while hurricane watch may not occur, hurricane warnings will most likely occur. Watch is usually issued hours before the warning is.
Answer:
the ratio of distance travelled by effort to the distance travelled by load in the machine is called velocity ratio (VR)
Answer:
Vf = - 20 m/s ( -ve sign shows that the particle is moving opposite to positive x- direction).
Explanation:
Given:
Vi = 20 m/s, m= 10 mg =1 × 10⁻⁵ kg, q= -4.0 × 10⁻⁶ C , E= 20 N/C. t= 5.0 s
first to find Electric Force
F= Eq = 20 × -4.0 10⁻⁶ C = - 8 × 10⁻⁵ N (-ve sign shows that the field will push the particle opposite to positive x- direction)
We also have F=ma
⇒ a = F/m = - 8 × 10⁻⁵ N / 10 × 10⁻⁵ kg = -8 m/s² ( -ve sign shows that the particle is accelerated opposite to positive x- direction)
Now according the first equation of Motion.
Vf = Vi + at
Vf = 20 m/s + -8 m/s² × 5 s
Vf= -20 m/s ( -ve sign shows that the particle is moving opposite to positive x- direction)
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.
