You are assigned the design of a cylindrical, pressurized water tank for a future colony on Mars, where the acceleration due to gravity is 3.71 m/s^2. The pressure at the surface of the water will be 150 kPa , and the depth of the water will be 13.6 m . The pressure of the air outside the tank, which is elevated above the ground, will be 93.0 kPa .
A) Find the net downward force on the tank's flat bottom, of area 2.15 m^2 , exerted by the water and air inside the tank and the air outside the tank.
Answers
Answer:
630.93 kN of force.
Explanation:
Pressure inside the tank is 150 kPa
The acceleration due to gravity on Mars g is 3.71 m/s^2.
The depth of water h is 13.6 m.
Pressure due to air outside tank is 93 kPa
The density of water p is 1000 kg/m^3
Pressure of the water on the tank bottom will be equal to pgh
Pressure of water = pgh
= 1000 x 3.71 x 13.6 = 50456 Pa
= 50.456 kPa.
Total pressure at the bottom of the tank will be pressure within tank and pressure due to water and pressure outside tank.
Pt = (150 + 50.456 + 93) = 293.456 kPa
Force at the bottom of the tank will be pressure times area of tank bottom.
F = Pt x A
F = 293.456 x 2.15 m^2 = 630.93 kN

Matter can undergo chemical reactions which feature of the components only stays the same in chemical reactions
Answers
In chemical reactions, the total mass of the components remains the same.
Chemical reactions involve the transformation of substances into new substances with different chemical properties. During these reactions, various changes occur, such as the rearrangement of atoms, the breaking and forming of chemical bonds, and the conversion of reactants into products. However, one fundamental principle that remains constant is the law of conservation of mass.
The law of conservation of mass states that matter cannot be created or destroyed in a chemical reaction. This means that the total mass of the reactants must be equal to the total mass of the products. No matter can be lost or gained during the reaction; it simply undergoes a rearrangement at the atomic or molecular level.
This principle holds true regardless of the complexity of the chemical reaction. Whether it involves simple reactions between two elements or complex reactions with multiple reactants and products, the total mass before and after the reaction remains constant.
This concept is vital in understanding stoichiometry, which is the quantitative relationship between reactants and products in a chemical reaction. By balancing chemical equations and applying the law of conservation of mass, scientists can determine the relative amounts of substances involved in a reaction.
Overall, while the physical and chemical properties of substances may change during a chemical reaction, the total mass of the components involved in the reaction remains constant.

When two light bulbs are connected in series, the resistance in the circuit is increase compared to that with one lightbulb. The increased resistance opposes the flow of current so far fewer electrons pass per second , transferring less energy. The lightbulbs are therefore not as bright as In a circuit with same voltage but only one bulb.
However, when Two lightbulbs are connected in parallel, each loop behaves like a separate circuit . The resistance in each branch is the same as if there were just one light bulb in the whole circuit.there is the same current in each branch of the circuit ,so the bulbs Will light up with the same brightness as a single bulb circuit. The energy stored in the battery will decrease twice as quickly and battery will run out faster than I series circuit.
6) explain the advantages and disadvantages of arranging components in series or parallel.
Answers
Advantages of Components Arranged in Series:
1. Increased resistance: Connecting components in series increases the overall resistance in the circuit. This can be advantageous in situations where you want to limit the flow of current or control the amount of power being dissipated.
2. Voltage sharing: In a series circuit, the total voltage of the power supply is divided among the components. This can be useful when you want to ensure that each component receives a specific voltage.
3. Current consistency: The current remains the same throughout the series circuit, which can be beneficial when you need to ensure a consistent current flow through multiple components.
Disadvantages of Components Arranged in Series:
1. Reduced brightness or performance: As mentioned in the question, when light bulbs are connected in series, the increased resistance reduces the flow of current, resulting in dimmer bulbs or reduced performance in other electrical devices.
2. Single point of failure: If one component in a series circuit fails, it can disrupt the entire circuit and cause all components to stop functioning.
Advantages of Components Arranged in Parallel:
1. Brightness and performance: When components such as light bulbs are connected in parallel, each component receives the full voltage, resulting in brighter bulbs and better performance in other devices.
2. Redundancy: In a parallel circuit, if one component fails, the other components can continue to function independently. This provides redundancy and ensures that the failure of one component does not affect the others.
3. Increased current capacity: Parallel arrangement allows the circuit to handle higher currents, which can be useful in situations where high power or heavy loads are required.
Disadvantages of Components Arranged in Parallel:
1. Increased complexity: Parallel circuits require more wiring and connections, which can make the circuit more complex and harder to manage.
2. Higher cost: Parallel circuits may require more components and wiring, resulting in higher costs for materials and installation.
It's important to consider the specific requirements and constraints of the application when deciding whether to arrange components in series or parallel. Each configuration has its advantages and disadvantages, and the choice depends on factors such as desired current flow, voltage distribution, and reliability.I
An aeroplaneflying above groundnd490m with 100 meterpersecond how far on ground it will strike
Answers
The airplane will strike the ground at a horizontal distance of 490 meters.
To determine how far the airplane will strike on the ground, we need to consider the horizontal distance traveled by the airplane during its flight.
The horizontal distance traveled by an object can be calculated using the formula:
Distance = Speed × Time
In this case, the speed of the airplane is given as 100 meters per second and the time it takes to cover the distance of 490 meters is unknown. Let's denote the time as t.
Distance = 100 m/s × t
Now, to find the value of time, we can rearrange the equation as follows:
t = Distance / Speed
t = 490 m / 100 m/s
t = 4.9 seconds
Therefore, it takes the airplane 4.9 seconds to cover a horizontal distance of 490 meters.
Now, to calculate the distance on the ground where the airplane will strike, we can use the formula:
Distance = Speed × Time
Distance = 100 m/s × 4.9 s
Distance = 490 meters
It's important to note that this calculation assumes a constant speed and a straight flight path. In reality, various factors such as wind conditions, changes in speed, and maneuvering can affect the actual distance traveled by the airplane.

A object of mass 3.00 kg is subject to a force Fx that varies with position as in the figure below.
answer : speed at x = 5 m = 3.35 m/s
speed at x = 15m = 5.12 m/s
Explanation:
initial speed( x = 0 ) = 2.5 m/s
speed at x = 5.00 m = ?
speed at x = 15 m = ?
Determine speed at x = 5 m
First we will apply the expression for work-energy theorem
w = \(\frac{1}{2} m(v^2 - v_{0}^2 )\) ----- ( 1 )
where : w = 7.50J, \(v_{0}\) = 2.5m/s , m = 3.0 kg ( in the expression of work )
input values into equation 1
7.50 = 1/2 (3 ) ( v^2 - 2.5^2 )
7.50 = 3/2 ( v^2 - 6.25 )
5 j/kg = v^2 - 6.25
∴ v = √11.25 = 3.35 m/s
Determine speed at X = 15
first we will determine the work done form x = 5 to x = 15
W = 7.5J + 15J + 7.5J = 30J, \(v_{0}\) = 2.5m/s , m = 3.0 kg
w = \(\frac{1}{2} m(v^2 - v_{0}^2 )\) --- ( 2 )
equation2 becomes
30J = 1/2 ( 3 ) ( v^2 - 6.25 )
30J = 3/2 ( V^2 - 6.25 )
20 J/kg = v^2 - 6.25
v = √26.25 = 5.12 m/s

A 0.22-caliber handgun fires a 28-g bullet at a velocity of 765 m/s. Calculate the de Broglie wavelength of the bullet.
Answers
Answer:
de Broglie wavelength of the bullet is 3.093 x 10⁻³⁵ m
Explanation:
Given;
mass of bullet, m = 28 g = 0.028 kg
velocity of the bullet, v = 765 m/s
de Broglie wavelength of the bullet is given by;
λ = h / mv
where;
λ is de Broglie wavelength of the bullet
h is Planck's constant = 6.626 x 10⁻³⁴ J/s
λ = h / mv
λ = (6.626 x 10⁻³⁴ ) / (0.028 x 765)
λ = 3.093 x 10⁻³⁵ m
Therefore, de Broglie wavelength of the bullet is 3.093 x 10⁻³⁵ m
The key insight that Bohr introduced to his model of the atom was that the angular momentum of the electron orbiting the nucleus was quantized. He introduced the postulate that the angular momentum could only come in quantities of nh/(2π), where h is Planck's constant and n is a nonnegative integer (0,1,2,3,…). Given this postulate, what are the allowable values for the velocity v of the electron in the Bohr atom? Recall that, in circular motion, angular momentum is given by the formula L= mvr.

in Bohr's atomic model the quantization postulate is that the angular momentum is equal to
L = n \(\hbar\)
we substitute
n \(\hbar\) = m v r
v = \(n \frac{\hbar }{m r}\)

A point charge of 1.0 C is 15 m from a second point charge, and the electric force on one of them due to the other is 1.0 N. What is the modulus of the second load? (k = 1/4πε0 = 8.99 × 109N∙m2/C2)
Answers
The modulus (or magnitude) of the second charge is approximately 3.34 × 10⁻⁶ C.
We can use Coulomb's law to solve this problem:
F = k * (q₁ * q₂) / r²
where F is the electric force between the two charges, q₁ and q₂ are the magnitudes of the charges, r is the distance between the charges, and k is the Coulomb constant.
We know that the electric force between the two charges is 1.0 N, that one of the charges has a magnitude of 1.0 C, and that the distance between the charges is 15 m. Therefore, we can solve for the magnitude of the second charge:
1.0 N = (8.99 × 10⁹ N∙m²/C²) * (1.0 C) * q₂ / (15 m)²
Solving for q₂, we get:
q₂ = (1.0 N) * (15 m)² / (8.99 × 10⁹ N∙m²/C²) ≈ 3.34 × 10⁻⁶ C
