A projectile's horizontal range on level ground is r=v20sin2θ/g. at what launch angle or angles will the projectile land at half
Ksju [112]

As given the formula of range is

R = \frac{v^2sin2\theta}{g}

now for the maximum range

\theta = 45

R_{max} = \frac{v^2}{g}

now for half of this maximum range we will have

\frac{R_{max}}{2} = \frac{v^2sin2\theta}{g}

\frac{v^2}{2g} = \frac{v^2sin2\theta}{g}

now from above we have

sin2\theta = \frac{1}{2}

so two possible values for above is given as

\theta = 15 degree, 75 degree

so above two angle we will have half of maximum range

A curve ball is a type of pitch in which the baseball spins on its axis as it heads for home plate. if a curve ball is thrown at
lesya692 [45]

The ball travels 18.3 m at a speed of 35.6 m/s.
How long does the trip take ?
time = (distance)/(speed) = (18.3 m) / (35.6 m/s) = 0.514 second

All during the trip, the ball is spinning at the rate of 29 rev/second.

Spinning at 29 rev/s for 0.514 sec, it completes  14.91 revolutions,
before stopping with a THUNK in the pocket of the catcher's mitt.

A chemical reaction takes place in which energy is absorbed. Arrange the characteristics of the reaction in order from start to
myrzilka [38]

Let’s create a diagram that shows the chemical reaction absorb energy. Take a look at the diagram I created that is attached to this answer.


Now, the start of the graph line is pretty flat and low leveled. This is the start, which is the reactants. The beginning of a chemical reaction that absorbs energy will almost always start with reactants. I labeled this this “Start: Reactants” and colored the text light green so you can easily detect the part I’m talking about.


Moving on, we see there’s a light blue arrow pointing from the the near bottom to the top curve of the graph line. This is the where the activation energy is rising. Activation energy is the difference between the reactants and products. When the graph line begins to cure, this is when the transition state is beginning. I labeled the transition state, “Transition State” and colored the text a light orange. I colored the line a light blue and also labeled it “Activation Energy” and colored the text light blue as well. I hope it’s easy enough for you to follow along. :)


Next we see that the graph line dips and then goes flat, but it doesn’t go low leveled. It says fairly higher than where it started. This is the end product. I labeled this “End: Product” and colored the text light purple so you can easily detect it.


Okay, now that that’s clear, let’s go ahead and fill in the first blank. According to the diagram we see that the start should be a reactant, and since the graph line starts out pretty low. So, this means that the first tile should be “Low energy of reactants."


Now the second tile should definitely be “Transition State.” This is because the second part in the diagram is transition state. Again, this is mainly where the activation energy is starting to rise.


As for the last and final tile, we should chose “High energy of products.” This is because the diagram is left off on a high leveled part at the end of the graph line.


So, when you place the tiles they should look something like this.


Low energy of reactants

↓

Transition state

↓

High energy of products
