The center of the thin disk is displaced 15 mm and then released. What is the maximum velocity attained by the center of the disk assuming no slip between the disk and the surface?
The maximum velocity is v= √10gh/7
The energy that an object has due to its location in a gravitational field is known as gravitational potential energy. When an object is close to the surface of the Earth, when the gravitational acceleration can be assumed to remain constant at roughly 9.8 m/s2, gravitational potential energy is most frequently used.
For the situation of the maximum velocity of the sphere when it hits the ground, the loss in gravitational potential energy is equal to the gain in translational kinetic energy and rotational kinetic energy.
mgh = mv² x I / 2.
mgh = 0.5 mv² + 0.5 (2/5 mR²)
The no-slip condition results in:
v=Rω
mgh = 0.5 mv + 0.2 mv

The system that controls such body processes as hormone balance, temperature and width of blood vessels is called the endocrine system.
In coordination with the nervous system, the endocrine system controls and maintains balance in the organ system. It does this by secreting hormones. The nervous system sends a signal to the endocrine system which secretes hormones to coordinate different processes in the body.
Hormones are chemical substances that circulate round the body and bind to a target cell, where they elicit a response. Special organs called endocrine glands secrete these hormones directly into the blood stream. For example, the pancreas secretes a hormone called insulin, and another one called glucagon. These two hormones work together to control the glucose levels in the blood.

Which formula is correct for calculating the ideal mechanical advantage?
Please help me.
effort distance/resistance distance or length of ramp/height of ramp or dE/dr is correct for calculating the ideal mechanical advantage
Theideal mechanical advantage would not have any friction. this is due to the fact that some of the effort put into the machine is lost trying to overcome friction.
ideal mechanical advantage is denoted by the sign IMA, that ignores the drawbacks of friction.
The force amplification achieved at "ideal" MA is measured without accounting for efficiency losses. Theoretically, a straightforward method might accomplish this level of amplification.One of the simplest representations of a mechanical advantage is a lever. You may model the mechanical advantage as follows:where the mechanical advantage corresponds to the a/b ratio. This is an illustration of a "perfect" mechanical advantage since no additional power is provided to the system or efficiency losses occur.

What is friction?Friction is a force that prevents two solid objects from rolling or sliding over one another. Although frictional forces, such as the traction required to walk without slipping, may be advantageous, they can provide a significant amount of resistance to motion. Automobile engines use about 20% of their output to overcome frictional forces in moving parts.
The adhesion forces between the contact zones of the surfaces, which are always microscopically uneven, appear to be the primary cause of friction between metals. Shearing these "welded" joints and the action of the tougher surface's imperfections scrubbing against the softer surface cause friction.
According to the question, Hannah is driving the car up a hill and when she is not pressing the accelerator the car slows down. The reason behind this is that there is an ascent of height that the car has to climb with its engine power and if the accelerator is not applied to it then it will start to slow down also friction is a factor that is involved in this case.

An electron starts from rest 24.5 cm from a fixed point charge with how fast will the electron be moving when it is very far away?
Consequently, an electron's speed at a very great distance is: 1.047 x 10 ^7 m/s
What is Electric Potential Energy?
The amount of work required to move one charge from infinity to a location close to the other charge is known as the electric potential energy of a system of two charged particles. When two charges exist in a system and are separated by an infinite distance, their electric potential energy is zero. The following mathematical formula can be used to express the electric potential energy of a system of two charged particles:
U =k⋅q1⋅q2/r
Where:
k is the coulomb's constant.
q1 is one of the charges.
q2 is the second charge.
initial speed of electron u = 0 m/s
mass of an electron is m= 9.11×10^−31 kg
Let v be the final velocity of the electron
When the electron is quite distant from the fixed charge, we are asked to determine its final speed. The system is being held together by a conservative force (electron and fixed charge) (electric force). As a result, we can apply the principle of mechanical energy conservation by equating the system's beginning mechanical energy (represented by the electron and constant charge) to the system's ultimate mechanical energy as follows:
MEi = MEf
KEi + PEi = KEf + PEf

Can mechanical energy ever be transformed completely into heat or internal energy?can the reverse happen? in each case, if your answer is no, explain why not; if yes,give one or two examples.
The reverse is not possible in this case
Explanation:Heat can be produced entirely from mechanical energy.
When a moving object slides across an uneven, level surface and eventually comes to a stop, all of its mechanical energy has been converted to heat.
Additionally, if a moving object were to compress a frictionless piston filled with an insulating gas, the gas would absorb the object's kinetic energy as internal energy.
By exerting force on its surroundings at the expense of its internal energy, a gas that expands adiabatically (without heat transfer) converts internal energy into mechanical energy.
That is undoubtedly the ideal (reversible) process.
Heat cannot be transformed completely into mechanical energy. This is related to the second law of thermodynamics.
And it is because while doing work some of the heat energy has to be expelled to a heat reservoir at low temperature.

Which involves the emission of less energy in the h atom, an electron moving from n = 4 to n = 2 or an electron moving from 3 to n = 2?
By transition energy, the emission of less energy in the h atom is an electron moving from n = 4 to n = 2.
We need to know about transition energy to solve this problem. Electrons in a hydrogen atom can move to another level of energy. It is also called a transition. In this process, electrons will absorb or release their energy to move. The transition energy can be determined as
ΔE = E2 - E1
where ΔE is transition energy, E2 is the final state of energy and E1 is the initial state of energy.
The state energy of a hydrogen atom can be calculated by
E = -(13.6) / n² eV
E = h.c / λ
where n is the number of energy states, h is Planck constant (4.136 x 10¯¹⁵ eV/Hz), c is speed of light (3 x 10⁸ m/s) and λ is wavelength.
From the question above, we know that
ΔE1 from n =4 to n = 2
ΔE1 from n =3 to n = 2
From the equation, we know that the transition energy is depends on the level state where
ΔE ~ (1/n2² - 1/n1²)
Hence
ΔE1 / ΔE2 = (1/n2² - 1/n1²) / (1/n2² - 1/n1²)
ΔE1 / ΔE2 = (1/2² - 1/4²) / (1/2² - 1/3²)
ΔE1 / ΔE2 = (3/16) / (5/36)
ΔE1 / ΔE2 = (3/16) / (5/36)
ΔE1 / ΔE2 = 1.35
ΔE1 = 1.35 ΔE2

By using uniform motion, with an initial speed 25.43 m/s and 2.60 seconds the ball will rise maximum height.
We need to know about the uniform motion to solve this problem. The uniform motion is an object's motion under acceleration. It should follow the rule
vt = vo + a . t
vt² = vo² + 2a . s
s = vo . t + 1/2 . a . t²
where vt is final velocity, vo is initial velocity, a is acceleration, t is time and s is displacement.
From the question above, we know that
h = 33m
vt = 0 m/s
g = 9.8 m/s²
The gravitational acceleration will be negative, hence
vt² = vo² - 2g . h
0² = vo² - 2. 9.8 . 33
vo² = 646.8
vo = √646.8
vo = 25.43 m/s
