Answer:

Approximately [tex]6.5 \times 10^{5}\; {\rm W}[/tex].

Explanation:

At a speed of [tex]v[/tex], the kinetic energy of the ride and the riders of mass [tex]m[/tex] (combined) would be:

[tex]\begin{aligned} \text{KE} &= \frac{1}{2}\, m\, v^{2}\end{aligned}[/tex].

If friction is negligible, [tex]\text{KE} = (1/2)\, m\, v^{2}[/tex] would be the work required to achieve this speed. That is:

[tex]\begin{aligned} \text{work} = \text{KE} = \frac{1}{2}\, m\, v^{2}\end{aligned}[/tex].

Given that this work was completed in a duration of [tex]t[/tex], the average power would be:

[tex]\begin{aligned} & (\text{average power})\\ =\; & \frac{(\text{work})}{(\text{time required})} \\ =\; & \frac{(1/2) \, m\, v^{2}}{t}\end{aligned}[/tex].

Substitute in [tex]m = 5000\; {\rm kg}[/tex], [tex]v = 27\; {\rm m\cdot s^{-1}}[/tex], and [tex]t = 2.8\; {\rm s}[/tex]:

[tex]\begin{aligned} & (\text{average power}) \\ =\; & \frac{(1/2) \, m\, v^{2}}{t} \\ =\; & \frac{(1/2) \times 5000\; {\rm kg} \times 27\; {\rm m\cdot s^{-1}}}{2.8\; {\rm s}} \\ \approx \; & 6.5 \times 10^{5}\; {\rm W}\end{aligned}[/tex].

(Note that if acceleration is constant, the power input to the ride would be proportional to [tex]t^{2}[/tex]. The average power of input to the ride would be a quarter of the peak power input. Multiplying average velocity (proportional to [tex]t[/tex]) by average force (proportional to [tex]t[/tex]) would overestimate the average power by [tex]100\%[/tex].)

Answer:

The temperature would be 95F .

Explanation:

At 95⁰F temperature, water has particles with a greater average kinetic energy than water with a temperature of 30°C.

Kinetic energy is a form of energy that an object possesses by virtue of its motion. It is defined as the energy that an object possesses due to its motion and is proportional to the mass of the object and the square of its velocity.

The formula for kinetic energy is:

KE = (1/2)mv²

Where KE is the kinetic energy, m is the mass of the object, and v is the velocity of the object.

Here in the question,

The kinetic energy of the particles in water increases with temperature. So, we need to find the temperature at which water has particles with a greater average kinetic energy than water at 30°C.

To compare the kinetic energy of water at different temperatures, we can use the formula:

KE = (1/2)mv^2

Where KE is the kinetic energy of the particles, m is the mass of a particle, and v is the velocity of a particle.

The average kinetic energy of the particles in water is proportional to the temperature in Kelvin, according to the formula:

KE = (3/2)kT

Where k is the Boltzmann constant and T is the temperature in Kelvin.

Using this formula, we can find the temperature at which water has particles with a greater average kinetic energy than water at 30°C:

KE1 = (3/2)k(30 + 273.15) = 4.14 x 10^-21 J

To find the temperature at which water has a greater kinetic energy, we need to find the temperature that corresponds to a kinetic energy greater than 4.14 x 10^-21 J.

Option A: 77°F = 25°C = 298.15K

KE2 = (3/2)k(298.15) = 5.06 x 10^-21 J

Option B: 95°F = 35°C = 308.15K

KE3 = (3/2)k(308.15) = 5.55 x 10^-21 J

Option C: 280K

KE4 = (3/2)k(280) = 4.85 x 10^-21 J

Option D: 300K

KE5 = (3/2)k(300) = 5.24 x 10^-21 J

Therefore, the temperature at which water has particles with a greater average kinetic energy than water at 30°C is Option B: 95°F (35°C or 308.15K).

The electric potential of the 4.5 × 10^(-5) C charge with an electric potential energy of 0.027 J is 600 J/C.

To find the electric potential (V) of a charge given its electric potential energy (U), you can use the formula:

V = U / q

where V is the electric potential, U is the electric potential energy, and q is the charge.

Plugging in the values you provided:

U = 0.027 J

q = 4.5 × 10^(-5) C

Using the formula, we can calculate the electric potential:

V = U / q

V = 0.027 J / (4.5 × 10^(-5) C)

To simplify the calculation, let's express the charge in scientific notation:

V = 0.027 J / (4.5 × 10^(-5) C)

V = 0.027 J / (0.000045 C)

Now divide 0.027 J by 0.000045 C to find the electric potential:

V ≈ 600 J/C

Therefore, the electric potential of the 4.5 × 10^(-5) C charge with an electric potential energy of 0.027 J is approximately 600 J/C.

Well !!! This question seems very interesting

Whenever we discussed about important topics in physics we generally referred galelio galilei, Issac newton and Albert Einstein.

Galelio, Newton and Einstein deserve these special recognition because they are responsible for taking physics/science towards modern era/technology .

If these three physicist/scientist were not in the world then I don't think so we will able to achieve modern technology this much earlier.

Galileo Galilei, Isaac Newton, and Albert Einstein indeed deserve special recognition in the field of physics due to their monumental contributions that revolutionized our understanding of the universe. While they built upon the work of their predecessors, their unique insights and groundbreaking discoveries have shaped modern physics significantly.

1. Galileo Galilei:

Galileo is often referred to as the "father of modern observational astronomy" and the "father of modern physics." He made pioneering observations using telescopes and provided experimental evidence to support the heliocentric model proposed by Nicolaus Copernicus. Galileo's observations of the moons of Jupiter and the phases of Venus further challenged the geocentric view of the universe prevalent at the time. He formulated the laws of motion, laying the groundwork for Newton's later work, and made key contributions to the study of projectiles, buoyancy, and mechanics. His emphasis on experimentation and empirical evidence set the stage for the scientific method.

2. Isaac Newton:

Newton's achievements are immense, and he is considered one of the greatest scientific minds in history. He formulated the laws of motion, universal gravitation, and calculus. His masterpiece, "Philosophiæ Naturalis Principia Mathematica," laid the foundation for classical mechanics and provided a comprehensive mathematical framework for understanding motion and forces in the universe. Newton's work profoundly influenced subsequent generations of physicists and played a crucial role in the scientific revolution of the 17th century.

3. Albert Einstein:

Einstein's contributions transformed our understanding of space, time, and gravity. His theory of special relativity introduced the concept of spacetime and challenged the classical notions of absolute space and time. In his theory of general relativity, Einstein proposed that gravity is the curvature of spacetime caused by the presence of mass and energy. This led to groundbreaking predictions, such as gravitational waves and the bending of light around massive objects. Einstein's work not only advanced theoretical physics but also had practical applications, such as the development of GPS technology.

While these physicists have received significant recognition, it is essential to acknowledge that the history of science is filled with brilliant minds who may not have achieved the same level of fame. One such overlooked physicist is Emmy Noether.

In conclusion, Galileo Galilei, Isaac Newton, and Albert Einstein deserve the special recognition they receive for their exceptional contributions to physics. However, it is important to remember that the history of science is replete with brilliant minds, and physicists like Emmy Noether also made indispensable contributions that have shaped our understanding of the universe.
