A) Calculate the torque required to accelerate the Earth in 7 days from rest to its present angular speed about its axis. (b) Calculate the energy required. (c) Calculate the average power required.
Answers
Answer:
A) 1.3013476 × 10²⁸ N·m
b) 2.8618128 × 10²⁹ J
c) 4.73183333 × 10²³ W
Explanation:
The mass of the Earth, M = 5.972 × 10²⁴ kg
The radius of the Earth, R = 6,371 km
The angular speed of the Earth, ω = 2·π/(24 hr) = 7.27220522 × 10⁻⁵ rad/s
The shape of the Earth ≈ Spherical
The moment of inertia of a sphere, I = (2/5)·M·R²
The angular acceleration of the Earth in 7 days from rest its present angular speed, ω, is given as follows;
α = 7.27220522 × 10⁻⁵ rad/s/((7 × 24 × 60 × 60) s) = 1.2024149 × 10⁻¹⁰ rad/s²
Torque, τ = I × α
∴ τ = (2/5) × 5.972 × 10²⁴ × 6,731,000² × 1.2024149 × 10⁻¹⁰ = 1.3013476 × 10²⁸
The torque required, τ = 1.3013476 × 10²⁸ N·m
b) The energy required, \(K.E. _{(Rotational)}\) = 1/2 × I × ω²
∴ \(K.E. _{(Rotational)}\) = (1/2) × (2/5) × 5.972 × 10²⁴ × 6,731,000² × (7.27220522 × 10⁻⁵ rad/s)²
The energy required, \(K.E. _{(Rotational)}\) = 2.8618128 × 10²⁹ J
c) Power = Energy/Time
Therefore, the average power required, P = \(K.E. _{(Rotational)}\)/Time
∴ P = 2.8618128 × 10²⁹ J/(7 × 24 × 60 × 60) s) = 4.73183333 × 10²³ Watts
The average power required, P = 4.73183333 × 10²³ Watts.

Answers
The electric charge of an atom is found by adding the charges carried by its protons and electron.
What is the function of electron here?The mass of an atom is primarily determined by the number of protons and neutrons it contains, since these particles contribute most of the atom's mass. Electrons, which are much lighter than protons and neutrons, contribute only a small fraction of the atom's total mass. Therefore, to determine the mass of an atom, you add the number of protons and neutrons it has.
In a neutral atom, the number of protons and electrons is equal, so the overall electric charge is zero. However, if an atom gains or loses electrons, it becomes charged and is called an ion. If an atom loses electrons, it becomes positively charged (since it has more protons than electrons), while if it gains electrons, it becomes negatively charged (since it has more electrons than protons). Therefore, to determine the electric charge of an atom, you add the charges carried by its protons and electrons.

The wing of an airplane experiences the forces as depicted in the vector diagram to the right. Using both one and two dimensional vector addition, find the result force acting on the wing. Give the magnitude and direction of the vector and draw the vector. (Show work)
Answers
Answer:
A.) 3605.6 N
B.) 33.7 degree
Explanation:
To find the result force acting on the wing of the airplane, we need to resolve the forces into x and y components
Resolving into x component :
Sum of forces = 3500 - 500 = 3000N
Resolving into y component:
Sum of forces = 2000N
Resultant force Fr = sqrt ( Fx^2 + Fy^2)
Fr = sqrt ( 3000^2 + 2000^2 )
Fr = sqrt ( 9000000 + 4000000 )
Fr = sqrt ( 13000000)
Fr = 3605.6 N
Therefore, resultant force acting on the wing is 3605.6 N
The direction of the vector will be:
Tan Ø = Fy / Fx
Substitute Fx and Fy into the formula
Tan Ø = 2000 / 3000
Tan Ø = 0.66666
Ø = tan^-1(0. 66666)
Ø = 33.7 degree.
The velocity v of wave set up in a stretched string, by plucking it can be given in terms of tension, F in the string length l of the string and mass m in the string as V=kF^xl^ym^z
Answers
The velocity (v) of a wave set up in a stretched string, caused by plucking it, can be described by the equation \(V = kF^x * l^y * m^z.\)
In this equation, F represents the tension in the string, l represents the length of the string, and m represents the mass of the string.
The exponents x, y, and z represent the respective powers to which the tension, length, and mass are raised. The values of x, y, and z depend on the specific characteristics of the string and the wave being produced.
The constant k represents the proportionality constant that relates the tension, length, and mass to the velocity of the wave. Its value is determined experimentally or can be derived from theoretical considerations.
This equation shows the dependence of the wave velocity on various parameters such as tension, length, and mass. By adjusting these parameters, we can manipulate the wave velocity in the string, thereby affecting the properties of the wave, such as frequency and wavelength.
Therefore, It is important to note that the specific values of x, y, and z, as well as the constant k, would need to be determined through experimentation or derived based on the specific properties of the string and the wave under consideration.

A bullet travelling horizontally with speed of 30m/s strike a wooden plank normal it surface, passing through it with a speed of 10m/s. Find the time taken by the the bullet to pass through the wooden plank of 5cm thickness
Answers
The bullet takes 0.0025 seconds to pass through the wooden plank of 5 cm thickness when it is traveling horizontally with an initial speed of 30 m/s and a final speed of 10 m/s.
The time taken by the bullet to pass through the wooden plank can be determined using the equation of motion for constant acceleration.
Given:
Initial speed (u) = 30 m/s
Final speed (v) = 10 m/s
Distance (s) = 5 cm = 0.05 m
To find the time taken (t), we need to calculate the acceleration (a) first. We can use the equation:
v² = u² + 2as
Rearranging the equation, we have:
a = (v² - u²) / (2s)
Substituting the given values:
a = (10² - 30²) / (2 * 0.05)
Simplifying the expression:
a = (-800) / (0.1)
a = -8000 m/s²
The negative sign indicates that the acceleration is in the opposite direction of the initial velocity.
Next, we can use the equation of motion:
v = u + at
Substituting the values:
10 = 30 + (-8000) * t
Simplifying the equation:
-8000t = -20
Dividing by -8000:
t = 20 / 8000
t = 0.0025 s
Therefore, the time taken by the bullet to pass through the wooden plank of 5 cm thickness is 0.0025 seconds.
To find the time taken by the bullet to pass through the wooden plank, we need to calculate the acceleration first using the equation of motion.
By rearranging the equation and substituting the given values, we can find the acceleration.
Then, using the equation of motion again, we can solve for time.
The negative sign in the acceleration indicates that it is in the opposite direction of the initial velocity.
The resulting time is 0.0025 seconds.

Marginalized individuals, including people with disabilities and those who identify as LGBTQ+, can experience significant impacts due to trauma, discrimination, negative attitudes, and exclusion. These factors contribute to physical and psychological harm, hinder access to opportunities and resources, and perpetuate systemic inequalities.
Marginalized individuals, such as people with disabilities, face unique challenges that can exacerbate the impact of trauma, discrimination, negative attitudes, and exclusion. Trauma experienced by individuals with disabilities may result from direct incidents or from the effects of living in a society that is not fully inclusive. Discrimination and negative attitudes towards people with disabilities can lead to social isolation, limited employment prospects, and reduced access to healthcare and education. This exclusion can have long-lasting effects on their mental health, self-esteem, and overall well-being. Similarly, individuals who identify as LGBTQ+ may also face trauma, discrimination, negative attitudes, and exclusion. LGBTQ+ individuals often encounter higher rates of bullying, harassment, and violence due to their sexual orientation or gender identity. These experiences can lead to psychological distress, anxiety, depression, and even post-traumatic stress disorder (PTSD). Discrimination and exclusion from healthcare, housing, employment, and social support systems further compound the challenges faced by LGBTQ+ individuals, hindering their ability to thrive and fulfill their potential.
In both cases, the impacts of trauma, discrimination, negative attitudes, and exclusion are far-reaching. They can contribute to a cycle of disadvantage, limiting opportunities for personal growth, social participation, and economic advancement. Recognizing and addressing these issues is essential for fostering a more inclusive society that supports the needs and rights of marginalized groups, empowering individuals to overcome the barriers they face and promoting their overall well-being.

Compared to visible radiation, does infrared radiation have longer or shorter wavelengths and higher or lower energy per photon?
Answers
Infrared radiation has longer wavelengths compared to visible radiation, and lower energy per photon.
What are infrared radiation?Infrared radiation (IR) is a type of electromagnetic radiation that is not visible to the human eye. It has a longer wavelength and lower frequency than visible light, and it is part of the electromagnetic spectrum that also includes radio waves, microwaves, visible light, ultraviolet radiation, X-rays, and gamma rays.
Infrared radiation is often associated with thermal radiation, which is the emission of electromagnetic waves from objects that are at a temperature above absolute zero. This is because infrared radiation is often emitted by objects that are warm, and it is this type of infrared radiation that is responsible for our ability to feel heat.
Infrared radiation has a wide range of applications, including in remote sensing, thermal imaging, and heating. For example, in remote sensing, infrared radiation can be used to observe and study the Earth and other celestial objects, as well as to detect and monitor changes in temperature, vegetation, and other physical properties. In thermal imaging, infrared cameras are used to detect heat signatures and create images based on temperature differences.

3.) A bicyclist of a mass of 40kg is riding through the streets of LA with a kinetic energy of 300
J. The bicyclist gets hit by a car and flings into the air and hits a building. How high did the bicyclist
travel in the air before hitting the building? Hint : KE = PE
Answers
The bicyclist traveled 10 meters in the air before hitting the building
We can get the above answers by following the steps below
Firstly we have to assume there are no external forces acting on the cyclist other than gravity.
When the bicyclist is about to hit the building, all kinetic energy will be converted into potential energy because of the height at which the cyclist is.
Therefore, we can equate the initial kinetic energy of the bicyclist to the potential energy at the highest point of their trajectory
Given
KE = PE
1/2 *m*v² = m*g*h
where m is the mass of the bicyclist (40 kg), v is their initial velocity before being hit, g is the acceleration due to gravity, and h is the height
Since we need to find h, we should isolate it by. Since the initial velocity isn't directly mentioned,we can assume the value to be 13.9
h = (1/2 * v²)/g
h = (1/2 * 13.9²)/9.81
h ≈ 10 meters
Therefore, the bicyclist traveled approximately 10 meters into the air before hitting the building.

According to Freud, the unconscious is a reservoir of thoughts, desires, memories, and emotions that are not readily accessible to conscious awareness. He believed that unconscious processes shape our thoughts, feelings, and behaviors, often in ways that we are unaware of.
Freud developed various techniques to explore the unconscious, such as free association and dream analysis. Through free association, he encouraged patients to speak freely and express their thoughts and associations without censorship, aiming to uncover hidden or repressed material that may be influencing their psychological well-being.
Dream analysis was another significant method used by Freud to explore the unconscious. He believed that dreams serve as a pathway to understanding unconscious desires, conflicts, and wishes. By analyzing the symbols and hidden meanings within dreams, Freud aimed to uncover the underlying thoughts and motivations that operate outside of conscious awareness.
By delving into the inner workings of the psyche and investigating the realms of dreams and the unconscious, Freud made significant contributions to the field of psychology and laid the foundation for psychoanalytic theory and practice.
Sigmund Freud is the influential figure who sought to explore the inner world of the psyche, including dreams and the unconscious. His work and theories, such as the concept of the unconscious mind and techniques like dream analysis, have had a lasting impact on the field of psychology and our understanding of the human mind.
