C.I dont know but that is my answer

The water level in the reservoir will rise to approximately 1.68 feet as a result of the storm. This calculation assumes vertical perimeter banks of the reservoir and provides an estimate of the expected water level rise resulting from the storm event.

To determine the rise in water level in the reservoir, we need to consider the ratio of the total runoff volume to the surface area of the reservoir. The rise in water level can be calculated using the formula:

Rise in water level = Total runoff volume / Reservoir surface area

Given information:

Total runoff volume = 32 acre-feet

Reservoir surface area = 19 acres

Converting acre-feet to cubic feet:

1 acre-foot = 43,560 cubic feet

Total runoff volume in cubic feet:

32 acre-feet * 43,560 cubic feet/acre-foot = 1,393,920 cubic feet

Calculating the rise in water level:

Rise in water level = 1,393,920 cubic feet / (19 acres * 43,560 square feet/acre)

= 1,393,920 cubic feet / 825,840 square feet

≈ 1.68 feet (rounded to two decimal places)

Therefore, the water level in the reservoir will rise to approximately 1.68 feet as a result of the storm.

Based on the given information of a total runoff volume of 32 acre-feet and a reservoir surface area of 19 acres, the rise in water level in the reservoir can be calculated. By converting the runoff volume to cubic feet and dividing it by the reservoir's surface area, we find that the water level will increase to approximately 1.68 feet. This calculation assumes vertical perimeter banks of the reservoir and provides an estimate of the expected water level rise resulting from the storm event.

The energy available through fusion for a 90 kg human body is approximately 5.67 x 10^13 joules. With this energy, the body could operate on fusion power for approximately 18,000 years.

Part A:

To calculate the energy available through fusion, we need to find 0.7% of the mass of the human body and convert it to energy using Einstein's famous equation E=mc^2.

Mass of the human body (m) = 90 kg

Conversion efficiency (η) = 0.7% = 0.007

Energy (E) = η * m * c^2

The speed of light (c) is approximately 3 x 10^8 m/s.

Plugging in the values:

E = 0.007 * 90 kg * (3 x 10^8 m/s)^2

Calculating:

E ≈ 0.007 * 90 kg * (9 x 10^16 m^2/s^2)

E ≈ 5.67 x 10^13 joules

Therefore, the energy available through fusion is approximately 5.67 x 10^13 joules.

Part B:

To find how long the body could operate on fusion power, we need to divide the available energy by the power consumption of the human body.

Given:

Average power of the human body (P) = 100 watts

The time (t) can be calculated as:

t = E / P

Plugging in the values:

t = (5.67 x 10^13 joules) / (100 watts)

Calculating:

t ≈ 5.67 x 10^11 seconds

To convert seconds to years, divide by the number of seconds in a year (approximately 31,536,000 seconds):

t ≈ (5.67 x 10^11 seconds) / (31,536,000 seconds/year)

According to Heisenberg's Uncertainty Principle, it is impossible to determine the position and momentum of a particle with absolute certainty at the same time. The Uncertainty Principle is defined as Δx * Δp ≥ h/4π, where Δx is the uncertainty in position, Δp is the uncertainty in momentum, and h is Planck's constant.
For the given problem, the uncertainty in position of a proton with mass 1.673 x 10-27 kg and kinetic energy 1.2 keV can be calculated as follows:

We know that the momentum p of a particle is given by p = mv, where m is the mass of the particle and v is its velocity.
The kinetic energy of the proton can be converted to momentum using the equation E = p²/2m, where E is the kinetic energy.
1.2 keV = (p²/2m)    (1 eV = 1.6 x 10^-19 J)
p²/2m = 1.92 x 10^-16 J
The momentum p of the proton can be calculated by taking the square root of both sides:
p = √(2mE) = √(2 x 1.673 x 10^-27 x 1.6 x 10^-16) = 7.84 x 10^-22 kg m/s

Using Heisenberg's Uncertainty Principle, we can calculate the uncertainty in position as follows:
Δx * Δp ≥ h/4π
Δx ≥ h/4πΔp
Substituting the values of h, Δp, and solving for Δx:
Δx ≥ (6.626 x 10^-34)/(4π x 7.84 x 10^-22)
Δx ≥ 2.69 x 10^-12 m

Therefore, the uncertainty in position of the proton is 2.69 x 10^-12 m.

Assuming the bungee cord is perfectly elastic, the jumper will reach a minimum distance of 14.7 meters from the ground after the cord has stretched.

What is distance?

Distance is the amount of space between two objects or points. It is typically measured in units such as meters, feet, or miles. Distance can also be measured in a more abstract sense, such as the amount of time it takes for something to happen or the amount of effort required to complete a task.

Distance can also refer to the difference between two things, such as the difference between two people’s opinions on a particular topic. Distance can also refer to physical separation, such as the distance between two people who are in different countries or cities. Distance can also be used to express the size of something, such as how far a car can travel on a single tank of gas.

Given: m = mass of jumper = 60kg

            h = height of cliff = 40m

Also,

k = F/x = 40N/1m = 40N/m

Now, when jumper jumps,

F = m×g

= 60×9.8

= 588 N

Therefore,

x = (588N)/(40N/m) = 14.7m

The distance of the object from the mirror is 18.3 cm.

The height of the object is 7.28 cm.

The magnification is greater than 1, which means the image is larger than the object, and it is upright.

Focal length of the convex mirror, f = 33 cm (positive for a convex mirror)

Distance of the image from the mirror, di = -19 cm (negative since the image is formed behind the mirror)

Height of the image, hi = 7.0 cm

To find the position and height of the object (the soda bottle), we can use the mirror formula:

\(\frac{1}{f}= \frac{1}{d_0} + \frac{1}{d_1}\)

where do is the distance of the object from the mirror. Rearranging the formula, we get:

\(\frac{1}{f}= \frac{1}{d_0} + \frac{1}{d_1}\)

\(\frac{1}{d_0}\) = 1/33 - 1/-19

\(\frac{1}{d_0}\)  = 0.0545

\(d_0\) = 18.3 cm

To find the height of the object, we can use theformula:

m = \(\frac{-d_i}{d_0}\)

m = -(-19)/18.3

m = 1.04

The acceleration due to gravity is constant even at the top of its flight and its direction will be towards to ground (Downwards).

The horizontal distance of an object in projectile motion relative to its origin is referred to as its range. Only at the highest point of a thrown object's flight does vertical (y) speed equal zero. This component of velocity does not change over time since there is no horizontal acceleration in the absence of air resistance.

For many people, this is a counterintuitive idea. (Depending on the object, air resistance will result in a little or major drop in velocity. However, for the time being, this aspect is disregarded.) Gravitational acceleration must be included in a vertical motion, and as a result, the vertical velocity evolves with time.

i) The total energy of the body at points A, B and C during the fall is the same because the law of conservation of energy.

ii) distance from A to B and final velocity is 44.3 m/s.

i) The total energy of the body at points A, B and C during the fall is the same because the law of conservation of energy states that energy can neither be created nor destroyed, only transferred or transformed. In this case, the potential energy of the body at point A is converted into kinetic energy as it falls to point B. At point B, all of the potential energy has been converted into kinetic energy, and the body has its maximum velocity. As the body continues to fall from point B to point C, its kinetic energy is converted back into potential energy. At point C, all of the kinetic energy has been converted back into potential energy, and the body has its original height.

ii) The distance from A to B can be found using the equation d = √2gh

, where d is the distance, g is the acceleration due to gravity, and h is the height. In this case, g = 9.8 m/s² and h = 100m, so d = √(2⋅9.8⋅100) = 44.3m.

The final velocity of the ball just before it reaches point C can be found using the equation v = √2gh

Answer: The force of attraction between the sun and earth is called gravity

Explanation:

Gravity is the force of attraction between two objects that is proportional to their masses and the distance between them. It is the force that keeps the Earth and other celestial bodies in orbit around the Sun, and it is also responsible for holding the Moon in orbit around the Earth. Newton's law of universal gravitation states that the force of gravity between two objects is proportional to the product of their masses and inversely proportional to the square of the distance between them. This means that the larger the masses of two objects and the closer they are to each other, the stronger the force of gravity between them will be. The force of gravity is a fundamental force in the universe, and it plays a crucial role in shaping the motion and structure of celestial bodies.

To find the magnitude of vector F3 using the tail-to-head method of vector addition, we can visualize the vectors F1 and F2 and then add them geometrically.

Let's assume that F1 is represented by an arrow with a certain magnitude and direction. Similarly, F2 is represented by another arrow with its own magnitude and direction. To find F3, we place the tail of F2 at the head of F1, maintaining the direction and magnitude. The resulting arrow drawn from the tail of F1 to the head of F2 represents the vector sum of F1 and F2.Now, we can extend the arrow representing F3, starting from the tail of F1 and ending at the head of F2. The length of this extended arrow represents the magnitude of F3. By measuring this length accurately, we can determine the magnitude of vector F3.It's important to note that this method assumes that F1 and F2 are represented accurately in terms of their magnitudes and directions.

v = 439 m/s

t = 2.17 ms = 2.17 × \(10^{-3}\) s

First, we should find the acceleration of the car. We assume that final speed of bullet after impact is 0 m/s, so here we go

a = v/t

a = \(v_{1}\) - \(v_{0}\) / \(t_{1}\)  - \(t_{0}\)

a = 0 - 439 / 2.17 × \(10^{-3}\)  - 0

a = -439 / 2.17 × \(10^{-3}\)

a = -439,000 / 2.17

a = -202,304.147 m/\(s^{2}\)

What actually happens when the result is negative is not the acceleration after the bullet hits the target, but the deceleration.

Now we got the amount of deceleration. We can found the force by the formula of: F = m.a but in the question there is no mass value of the bullet. So, we can answer this question by this way (we can ignore negative values)

F = m.a

F = m × 202,304.147 m/\(s^{2}\)

Acceleration (a) is the change of velocity (Δv) over the change of time (Δt), and here is the formula, a = Δv/Δt. This formula allows you to measure how quick velocity changes in meters per second squared (m/s. Acceleration is also a vector quantity, so it includes both magnitude and direction.
