Mike Powell's range was 0.26 m less than the maximum possible range.
We know that,
Horizontal range of the projectile on a flat ground is,
R = v² sin 2θ / g
where,
R = Range
v = Velocity
θ = Angle of projection
g = Acceleration due to gravity
Given that,
v = 9.5 m / s
The maximum possible range of a projectile is achieved when the angle of projection is 45°
R = 9.5² sin 90° / 9.8
R = 9.21 m
The difference between maximum range and Mike Powell's range is
R = 9.21 - 8.95
R = 0.26 m
In a projectile motion, range is the horizontal distance between starting and ending point.
Therefore, Mike Powell's range was 0.26 m less than the maximum possible range.

High temperature and pressure tend to favor flow rather than breakage, so it is surprising that large, very deep earthquakes are sometimes observed, occurring in warm places where the pressure is high. What is accurate about these rare, deep earthquakes?.
They happen at subduction zones, where shifting mineral assemblages appear to "implode" as a result of increased pressure on the rock as it is subducted deeper.
"Implosion" is the idea that is currently preferred. As subduction zones transfer rocks deeper where pressure is stronger, the building blocks frequently reorganize to take up less space, changing from, for example, a fit-in-the-gap-between-those-below arrangement to one that places rocks one on top of another. Sometimes, this can seem to develop gradually until coming to a head suddenly (I can't move until my neighbor does...), leading to an implosion. The biggest, deepest earthquakes happen where temperatures and pressures are so extreme that we can't even envision rocks breaking. Humans have never excavated a tunnel, not as deep as the earthquakes. Most nuclear bomb tests have been completed. Major nuclear weapons are substantially smaller than large earthquakes.)

a train travels 220km in 1.5 hours. what’s the average velocity?
Answer:caca
Explanation:
because
A person riding in an airplane drops a rock out of the door of the plane which is moving at 550 mile/hr. The airplane remains on its original horizontal path and maintains a constant velocity. Where will the airplane be located when the rock hits the ground? neglect air resistance.
By using uniform motion, the location of the airplane when the rock hits the ground is ( 550 . √(2h/g) + h )miles.
We need to know about the uniform motion to solve this problem. The uniform motion is an object's motion under acceleration. It should follow the rule
vt = vo + a . t
vt² = vo² + 2a . s
s = vo . t + 1/2 . a . t²
where vt is final velocity, vo is initial velocity, a is acceleration, t is time and s is displacement.
From the question above, we know that
vo = 550 mile/h
Find the time taken to hit the ground
s = vo . t + 1/2 . a . t²
h = 0 . t + 1/2 . g . t²
t² = 2h/g
t = √(2h/g)
Find the distance traveled by plane
s = vo . t + 1/2 . a . t²
x = vo . t + 1/2 . a . t²
x = 550 . √(2h/g) + 1/2 . g . √(2h/g)²
x = 550 . √(2h/g) + h

Explanation:
Karen is asked to look at two spots of light and judge which one gets brighter over time. Both spots start out at 100 units of brightness. She notices that the right spot is brighter when it is 110 units. If she is presented with two new spots of light both starting at 300 units, how much brighter will one have to get before she will be able to reliably detect the difference?.
As spots start out at 100 units of brightness. One of the light spots will have to get 330 units brighter than the other for her to be able to tell the difference.
In the case of the first bulb, she noticed the difference when the right was 0.10 % brighter than the other one.
100 * 0.10 = 10
100 + 10 = 110
If we apply the same sense in the second case, one of the spots will have to be 0.10% brighter than the other.
300 * 0.10=30
300+30 = 330
In order to tell the difference, the other spot should be at 330 units of brightness.
The unit of brightness is Lumen. It is use to calculate the total amount of brightness emitted from a source over a unit of time.

A star is moving directly toward earth at a large fraction of the speed of light. The light we observe from this star compared to the light received from the same star if it were at rest relative to earth will be blueshifted.
In Physics, this phenomenon is called doppler shift as it refers to the change in frequency of the waves relative to an observer who is moving in relation to that source.
A star coming toward earth emits light that appears to have a shorter wavelength as compared to another source of light.
When the star is moving toward earth, its spectral line shift towards the blue end of the light series.
Since blue light has a shorter wavelength and this occurrence corresponds to the blue end of the light spectrum hence called blueshift.

The books has a mass of 3.5kg. the coefficient of friction between the book and the wall is 0.85.how much force must be applied to keep the book from slliding
The force that must be applied to keep the book from sliding is 41.17 N.
When a body is pressed against a wall, the four forces act on it, as shown in the image Applied force, Frictional Force, Weight and Normal Force.
To keep the book from sliding, the forces should balance each other in the horizontal and vertical directions. Thus, Applied Force and Normal Force should be equal. And Frictional force and Weight should be equal.
Hence, Applied Force = Normal Force(N)
Frictional Force = Weight (mg)
μN = mg
As applied force = N
μ x applied force = mg
0.85 x Applied Force = 3.5 x 10
Applied Force = 41.17 N
Hence, the force that must be applied to keep the book from sliding is 41.17 N.

1.00 atm. If the pressure was
increased to 4 058 mmHg,
calculate the final volume of
the container. Assume that the
temperature is constant.
The final volume of the container that contains argon gas at 4058 mm of Hg is 93.80 L.
Given in the question
Initial pressure = 1.00 atm = P1
Initial volume = 500 L = V1
Final Pressure = 4058 mm of Hg = P2
To find
Final Volume = V2
Now, the unit of pressure is different for each case, So we need to convert mm of Hg into atmospheric pressure.
Using unitary method
760 mm of Hg = 1 atm
1 mm of Hg = 1/760 atm
1×4058 mm of Hg = 1/760 × 4058 atm
4.058 mm of Hg = 4058/760 atm
4.058 mm of Hg = 5.3 atm
Now as it is given in the question that the temperature remains constant, we can apply Boyle's law.
By using Boyle's law
P1V1 = P2V2
Put in the value
(1.0)(500) = (5.3)(V2)
V2 = 500/5.3
V2 = 93.80 L

assume there is friction between the wagon and the ground. how do you determine the value of the frictional force, using the y component of the applied force f?
The value of frictional force, using the y component of the applied force f can be found if the co- efficient of friction is known.
First split the applied force F into its vertical and horizontal components [tex]F_{y}[/tex] and [tex]F_{x}[/tex] respectively
[tex]F_{y}[/tex] = F sin θ
Since there is no vertical movement,
Σ [tex]F_{y}[/tex] = 0
[tex]F_{y}[/tex] + [tex]F_{N}[/tex] - mg = 0
[tex]F_{N}[/tex] = [tex]F_{y}[/tex] - mg
[tex]f_{k}[/tex] = [tex]([/tex]μ[tex])_{k}[/tex][tex]F_{N}[/tex]

We get the speed of the wave when we divide the frequency of sound waves in front of the plane by frequency behind the plane.
Assume the source s, is behind, and the listener l, is in front of the plane. The formula for the doppler effect is given by:
fL=((v±vL )/(v±vS)) fS
Thus, dividing the frequency of sound waves in front of the plane by frequency behind the plane gives the speed of the waves.
where fL is the frequency perceived by the observer (listener),
fS is the frequency of the source,
v is the speed of the waves,
vL the speed of the listener and
vS the speed of the source.
The Doppler Effect is the shift in observed frequency of a wave caused by the movement of the source or detector relative to the transmitting medium. The Doppler Effect happens when a wave source and/or observer move relative to one other, resulting in the observer measuring a different frequency of the waves than the source.

Answer:
R = V^2 sin 2 θ / g range formula
max range occurs at θ = 45 deg
R = 50^2 m^2/s^2 / 10 m/s^2 = 250 m
The maximum value of angle theta for a velocity of 50 m/s will be 11.47 °, where the final velocity of the bullet is zero and the acceleration due to gravity is 10.
What is velocity?Velocity is a vector quantity measuring the distance covered by an object per unit time. The rate of change in velocity is called acceleration. Velocity have two component one in horizontal axis and other in vertical axis.
For horizontal axis Vh = V cos∅
for vertical axis Vv = V sin∅.
The final velocity V = u + at. Where u is the initial velocity.
Here V = 0 thus u = at.
t = u/a = 50 m/s / 10m/s².
t = 5 seconds.
v = 50 cos∅ = at
