(a) The initial horizontal velocity of the driver is 10 m/s.
(b) The time taken for him to reach the water is 1.75 s.
(c) The horizontal displacement is 17.5 m.
Horizontal velocity of the driver (Vx)
The initial horizontal velocity of the driver is given as 10 m/s.
Time of motion of the driverh = vy(t) + ¹/₂gt²
where;
vy is initial vertical velocityt is time of motionh is height of fallh = 0 + ¹/₂gt²

What is the index of retraction?
Light bends when it travels from a certain density of matter into a different density of matter. The density of the stuff affects how much it bends. Light bends when it transitions from air to water or from water to air. Light bends when it travels from water to glass or from glass to air. How much light is bent by a particular substance may be determined by its index of refraction. However, Snell's Law and the angle of incidence must be coupled. The angle of refraction increases with increasing angle of incidence. As a result, the water's unique index of refraction bends light entering the medium at an angle of 30°. and that is 1.33. This means that light in a vacuum travels at 1.33 times faster than light in water. We wouldn't have lenses in the way we do now without refractive index. We would need eyes with pinhole-sized openings in order to see, which would prevent us from seeing clearly or at least in great detail. We wouldn't have had microscopes to view anything in great detail, telescopes to view the moon, planets, or distant things. I could go on, but I think you get the idea: if we didn't have the material characteristic known as refraction, things would be quite different. Well, I guess it's possible that human eyes have evolved to have diffractive lenses, but that's another theory.
________________________
The ability of a substance, whether it is solid, liquid, or gas, to reflect light causes it to move more slowly than it would in a vacuum.
Any substance's refractive index (n) is found by dividing the speed of light in that substance by the speed of light in a vacuum (c) (v).
So
n = c/v
Since a material's refractive index varies depending on the wavelength of light, n = f(wavelength) (n is a function of wavelength). In comparison to longer wavelengths, the index is larger for shorter wavelengths. It's known as dispersion.
When creating lenses or other refractive optical systems, the refractive index and dispersion are both crucial factors. The diverse wavelengths don't come to a common focus, which has a disastrous effect on image quality because index is directly related to how light bends while passing through a lens. We refer to this as chromatic aberration. It's difficult to regulate, but you can achieve it by carefully selecting various glass chemistries and massaging them into position. The glass map showing index as a function of inverse dispersion is seen in the image below. About 20 to 100 is the range of the Abby number, a measure of dispersion; lower numbers indicate more dispersion (larger index difference between red and blue light). Every dot stands for a distinct glass.
Refractive indices range from 1.0003 for air, to over 4.5 for Geranium.

If you take a given pendulum to the Moon, where the acceleration of gravity is less than on Earth, the resonant frequency of the pendulum will Group of answer choices
The resonant frequency will decrease.
The natural frequency of an object, where it typically vibrates with a greater amplitude, is another way to describe the resonant frequency.
The formula for time period of pendulum(T) is
T= 2π[tex]\sqrt{} \frac{l}{g}[/tex] where,
l= length of pendulum
g = acceleration due to gravity
So, T is inversely proportional to the square root of g(√g)
It means as the value of g decreases, time period of pendulum increases and vice versa.
As it is given, value of g is less on moon than on earth and it is approx. 6 times less than that of earth.
That's why time period of oscillation of pendulum increases.
Now, as we know that time period is inversely proportional to the frequency.
So as the time period of pendulum on the moon increases, its resonant frequency decreases.
Hence, If we take a given pendulum to the Moon, where the acceleration of gravity is less than on Earth, the resonant frequency of the pendulum will decrease.

Calculate the additional work required by F to stretch the spring by an additional 13.7 cm from that position.
When the spring is stretched by 15.2 cm = 0.152 m, the spring exerts a restorative force with magnitude (due to Hooke's law)
[tex]F = kx[/tex]

If you mix 100 g of ice at 0 ∘c with 100 g of boiling water at 100 ∘c in a perfectly insulated container, the final stabilized temperature will be.
The final stabilized temperature will be between 0 °C and 50 °C.
Calorimetry:
The enthalpy of fusion of ice is 334 J/g. The specific heat of water is 4.2 J/g.
To cool 100 g of water from 100 °C to 0 °C would require the removal of
4.2 x 100 x 100 = 42000 J.
To melt the ice would require the addition of
334 x 100 = 33400 J
∴ 42000 > 33400 thus you can melt all the ice and have some heat to spare, specifically 42000 - 33400 = 8600 J
Now use this to warm up 100+100 = 200 g of water at 0 °C

Someone on Earth would measure the star Vega to be 25 light years away. If you fly a spaceship to Vega at 0.999c, you will measure the distance to be: Group of answer choices
If you fly a spaceship to Vega at 0.999c, you will measure the distance to be much less than 25 light years.
Most space objects use light-years to represent their distance. Light-years are the distance that light travels during the year on Earth. Light-years are about 6 trillion miles (9 trillion km). This is a 6 followed by 12 zeros.
At the same speed, a movement equivalent to one light-year takes about 11.3 billion days. Life expectancy for Americans is currently estimated at 78.74 years, which is equivalent to 28,740 days. Therefore, to get there, you need to live about 400,000 times as long as the average American.

At which point is the velocity the greatest? at which points is the velocity 0 m/s? at which point is the acceleration 0 m/s2? at which points is the acceleration the greatest?
As per the image: The velocity is maximum at B. The velocity is O at C and A. The acceleration will be O at B
The acceleration is maximum at C and A.
How can it be said?
Two sketches are shown in the attached image. The first one is based on the principle of energy conservation, and it is simple to understand when the velocity is at its highest and when it will be zero.
The pendulum is at its highest height in points A and C relative to the reference point, giving us the most potential energy. Additionally, all of the potential energy had been converted into kinetic energy by the time the pendulum reached point B, therefore this is where its maximum velocity would be.
The second sketch, which displays a free body diagram of the pendulum when it is producing a theta angle with respect to the vertical plane, is shown for the acceleration analysis. Applying Newton's second law and taking into account the forces acting on the pendulum, we arrive at the equation shown in the picture.
With the knowledge that the equation will be zero (0) when the angle theta is 0, we can see that the acceleration, which has the same direction as the velocity, relies on the sin(theta). It implies that at point B, the acceleration will be 0. and at points Cand A, maximum.
