The total impulse delivered to the ball by the golf club is 3.116 kg m/s.
To calculate the impulse delivered to the ball by the golf club, we can use the impulse-momentum theorem, which states that the impulse delivered to an object is equal to the change in momentum of the object.
First, we need to convert the distance of 455 meters to the initial velocity of the golf ball. We can use the fact that the range of a projectile launched at an angle of 0 degrees is given by:
\(R = (v^2 / g) * sin(2θ)\)
where v is the initial velocity of the ball, g is the acceleration due to gravity, and θ is the launch angle (in this case, 0 degrees).
Since the ball is assumed to be launched at the optimal angle for maximum range, we can set θ = 0 and solve for v:
\(v = sqrt(R * g / sin(2θ)) = sqrt(455 * 9.81 / sin(0)) = 67.77 m/s\)
Next, we can calculate the initial momentum of the ball:
\(p = m * v = 0.046 kg * 67.77 m/s = 3.116 kg m/s\)
Finally, we can use the fact that the club is in contact with the ball for 1/200 of a second to calculate the impulse delivered:
\(I = Δp = mΔv = m(vf - vi) = 0.046 kg * (0 - 67.77 m/s) = -3.116 kg m/s\)
Note that the negative sign indicates that the impulse is in the opposite direction of the initial momentum, which makes sense since the club is delivering a force to the ball in the opposite direction of its motion.

What do you predict would happen if you brought a negatively charged balloon next to an uncharged piece of paper?.
A portion of the paper near the balloon becomes positive when you place the balloon close to a small piece of paper because the negative charge balloon repels the electrons charge in the paper.
Electric charge, a fundamental characteristic of matter carried by some elementary particles, controls how an electric or magnetic field affects the particles. Positive or negative electric charge exists in distinct natural units and cannot be created or destroyed.
Positive and negative charges are the two main categories of electric charges. When two objects are relatively close to one another and one type of charge is present in excess, they repel one another. When they are relatively close to each other, two objects with excess opposite charges—one positively charged and the other negatively charged—attract to one another.

In many locations, old abandoned stone quarries have become filled with water once excavating has been completed. While standing on a 10.0 m high quarry wall, Clarence tosses a piece of granite into the water below. If Clarence throws the rock horizontally with a velocity of 3.0 m/s how far out from the edge of the cliff will it hit the water?
Answer:
Explanation:
Let us calculate the time of flight first using the formula;
Velocity = Displacement/Time
Time = Displacement/speed
Time = 10.0/3
Time = 3.33secs
Next is to calculate how far out from the edge of the cliff it will hit the water. To get that, we will use the equation of motion;
S= ut+1/2gt²
u is the initial velocity = 0m/s
g is the acceleration due to gravity = 9.81m/s
S = 0 + 1/2(9.81)(3.33)²
S = 4.905*3.33*3.33
S = 54.39m
Hence it will hit the water at 54.39m from the edge of the cliff
Answer:
It will hit the water at \(4.28m\) off the cliffExplanation:
Applying kinematic relations along vertical direction
\(y = V_0t + \frac{1}{2}a_yt^2\)
where,
\(a_y = g\)
therefore,
\(y = 0 + \frac{1}{2}gt^2\)
The time taken
\(t = \sqrt{\frac{2y}{g}}\\\\t = \sqrt{\frac{2*10}{9.8}}\\\\t = 1.428s\)

monochromatic light is incident on a metal surface, and electrons are ejected. if the intensity of the light increases, what will happen to the maximum energy of the electrons? monochromatic light is incident on a metal surface, and electrons are ejected. if the intensity of the light increases, what will happen to the maximum energy of the electrons? the maximum energy will increase. changes in the maximum energy cannot be determined without additional information. the maximum energy will decrease. the maximum energy will remain the same.
When monochromatic light is incident on a metal surface, electrons may be ejected from the surface due to the photoelectric effect.
The energy of the ejected electrons is determined by the energy of the incident photons minus the energy required to overcome the work function of the metal (i.e., the minimum energy required to remove an electron from the metal).
The maximum energy of the ejected electrons is reached when the energy of the incident photons is equal to or greater than the work function of the metal.
If the energy of the incident photons is increased beyond this threshold, the maximum energy of the ejected electrons will not change.
However, if the intensity of the incident light is increased (i.e., the number of photons incident on the metal surface per unit time is increased), the number of ejected electrons per unit time will increase.
Since the energy of each ejected electron is determined by the energy of the incident photons, increasing the number of photons incident on the metal surface per unit time will increase the number of ejected electrons with higher energy (i.e., the maximum energy of the ejected electrons will increase).
This is because more electrons will be able to absorb photons with energies greater than the work function of the metal and gain higher energies as a result.
Therefore, the correct answer is: the maximum energy will increase.

the new porsche taycan turbo S can accelerate from 0 to 100km/hr in 2.80s. The Tesla P100D can accelerate from 0 to 60 miles/hr to 2.28. Assume both are accelerating constantly.
a. How quickly can each car accelerate (in m/^2)
b. Which car will be faster after 2 seconds.?
The Porsche taycan turbo S can accelerate at 35.71 m / s² and the Tesla P100D can accelerate at 42.35 m / s². Tesla P100D will be faster after 2 seconds.
a = ( v - u ) / t
a = Acceleration
v = Final velocity
u = Initial velocity
t = Time
For Porsche taycan turbo S,
u = 0
v = 100 km / h
t = 2.8 s
a = ( 100 - 0 ) / 2.8
a = 35.71 m / s²
For Tesla P100D,
u = 0
v = 60 mi / h = 96.56 km / h
t = 2.28 s
a = ( 96.56 - 0 ) / 2.28
a = 42.35 m / s²
At t = 2 sec,
\(v_{P}\) = \(a_{P}\) * t
\(v_{P}\) = 35.71 * 2
\(v_{P}\) = 71.42 m / s
\(v_{T}\) = \(a_{T}\) * t
\(v_{T}\) = 42.35 * 2
\(v_{T}\) = 84.7 m / s
\(v_{T}\) > \(v_{P}\)
Therefore,
(a) The Porsche taycan turbo S can accelerate at 35.71 m / s² and the Tesla P100D can accelerate at 42.35 m / s²
(b) Tesla P100D will be faster after 2 seconds.

during which stage does the star have an inert (nonburning) helium core?
The stage during which a star has an inert helium core is the red giant phase. As a star age, it undergoes nuclear fusion reactions that cause it to expand and become less dense. In the case of low to intermediate-mass stars (such as our Sun), this expansion causes the star to become a red giant.
During this phase, the outer layers of the star expand and cool, causing it to appear reddish in color. At the same time, the core of the star becomes hotter and denser as it continues to fuse hydrogen into helium.
Eventually, the hydrogen in the core is depleted and the star switches to fusing helium into heavier elements. This causes the core to shrink and become hotter, but the outer layers of the star continue to expand. As a result, the helium in the core becomes inert and nonburning. The star will eventually shed its outer layers, leaving behind a small, hot core known as a white dwarf.

why doesn't a pure liquid in a distilling flask vaporize all at once
A pure liquid in a distilling flask doesn't vaporize all at once because of its vapor pressure. The temperature of a liquid determines its vapor pressure. At higher temperatures, the vapor pressure of a liquid increases. When a pure liquid is heated in a distilling flask, its temperature increases, resulting in a rise in vapor pressure.
However, the vapor pressure is only equivalent to atmospheric pressure at the boiling point of the liquid. If the boiling point of the liquid is equal to or lower than the temperature of the distilling flask, the liquid will boil and vaporize, and the distillate will accumulate in the receiving flask. Based on the aforementioned discussion, the temperature of the liquid continues to rise when the temperature of the distilling flask is increased. This, in turn, causes the vapor pressure of the liquid to rise as well. When the vapor pressure of the liquid rises above atmospheric pressure, the liquid begins to boil.
However, the boiling point of a liquid is dependent on its atmospheric pressure. If the atmospheric pressure is lower, the boiling point of the liquid decreases, and if the atmospheric pressure is higher, the boiling point of the liquid increases. Furthermore, if the atmospheric pressure is lower than the vapor pressure of the liquid at a specific temperature, the liquid would evaporate completely. As a result, a pure liquid in a distilling flask does not vaporize all at once because it is boiling at a temperature less than the atmospheric pressure.
