A cyclist is rounding a 20-m radius curve at 12 m/s. What is the minimum possible coefficient of static friction between the bike tires and the ground?
The minimum possible coefficient of static friction between the bike tires and the ground is 0.734.
The minimum possible coefficient of static friction is that at which the moving object is on the verge of the stopping state.
Radius of the curve, (R) = 20 m.
Velocity of the cyclist, (v) = 12 m/sec
g = 9.81 m/s²
On a circular curve, the cyclist will experience the centrifugal force(F) which acts outwards. This force is,
F = mv²/R
This centrifugal force(F) is balanced by the static friction force(Fₓ). Which is,
Static friction force = mg × coefficient of static friction(Ц)
mv²/R = mg × coefficient of static friction(Ц)
coefficient of static friction(Ц) = v²/gR
= (12×12)/(9.81×20)
= 0.734

When a driver brakes an automobile, friction between the brake disks and the brake pads converts part of the car's translational kinetic energy to internal energy. If a 1600 kg automobile traveling at 42.8 m/s comes to a halt after its brakes are applied, how much can the temperature rise in each of the four 3.5 kg steel brake disks? Assume the disks are made of iron (cp = 448 J/kg·°C) and that all of the kinetic energy is distributed in equal parts to the internal energy of the brakes.
The temperature can rise 234° C in each of the four 3.5 kg steel brake disks.
What is law of conservation of energy?Energy cannot be created or destroyed, according to the law of conservation of energy. However, it is capable of change from one form to another. An isolated system's total energy is constant regardless of the types of energy present.
According to law of conservation of energy:

The mass of the load is 50,000N/m multiplied by 10.0cm, which is 500,000N.
Hooke's law states that the force (F) required to extend or compress a spring by some distance (x) scales linearly with respect to that distance—that is, Fs = kx, where k is a constant factor characteristic of the spring (i.e., its stiffness) and x is small in comparison to the total possible deformation of the spring.
B. Using Hooke's law, F = kx, where F is the force of the truck's hock, k is the spring constant, and x is the compression of the hock. Rearranging for mass, m = F/g, where g is the acceleration due to gravity. Thus, m = kx/g, or m = (50,000N/m * 10.0cm)/9.8m/s^2, which yields 500,000N.

How did the heavy elements originate and what did they create?
Heavy elements, such as gold, silver, and mercury, as well as the elements that make up the earth's core, such as iron and nickel, originated in the hearts of stars. They were created through the process of nuclear fusion, which occurs when the temperatures and pressures inside a star are high enough to overcome the electrostatic repulsion between the positively charged nuclei of atoms.
What are heavy element?When fusion occurs, the nuclei of the atoms merge, creating a new, heavier element. This process is called nucleosynthesis. The fusion of lighter elements, such as hydrogen and helium, produces heavier elements, such as carbon, oxygen, and neon.
Therefore, most heavy elements, such as gold and platinum, are created in supernovae, massive explosions that occur when the fuel in a star runs out, and the star collapses under its own gravity. The intense pressure and temperatures that are created during the collapse cause the nuclei of atoms to fuse together, creating elements with atomic numbers higher than iron.

A person pushes a lawnmower across 20 meters of grass. If the person pushes with 37 Newtons of force while pushing downward at an angle of 15 degrees below the horizontal, what is the amount of work the person does on the lawnmower?
Therefore, the amount of work done on the lawnmower is: W=Fdcosθ=(37 N)(20 m)cos15∘≈710J if is the amount of work the person.
What is the simple definition of work?Work is force applied over distance. Examples of work include lifting an object against the Earth's gravitation, driving a car up a hill, and pulling down a captive helium balloon. Work is a mechanical manifestation of energy. The standard unit of work is the joule (J), equivalent to a newton - meter.
What is work and energy?Work is defined as transferring energy into an object so that there is some displacement. Energy is defined as the ability to do work. Work done is always the same. Energy can be of different types such as kinetic and potential energy.

Order the molecules from the strongest intermolecular force (top) to the weakest (bottom). Refer the table of electronegativities to help you.
The order of intermolecular forces among the given compounds will be as follows: H F > H Cl > H Br > H I
Electronegativity is defined as the property of the element to attract the shared pair of electrons towards itself.
Strongest intermolecular forces of attraction means that the electronegativity difference between the elements forming bond is more, more polar is the bond.
Electro negativities of the elements are:
Hydrogen: 2.1
Fluorine: 3.98
Chlorine: 3.16
Bromine: 2.96
Iodine: 2.66
Electro negativity difference in H F = 3.98 - 2.1 = 1.88
Electro negativity difference in H Cl = 3.16 - 2.1 = 1.06
Electro negativity difference in H Br = 2.96 - 2.1 = 0.86
Electro negativity difference in H I = 2.66 - 2.1 = 0.56
As, the electronegativity difference of H F is the highest, so it has the strongest intermolecular forces of attraction.
Thus, the order of intermolecular forces among the given compounds is H F > H Cl > H Br > H I.

If two identical springs are put in parallel (side by side), what exactly
happens to the overall spring constant? Why?
The springs generate a combination of forces.Therefore, it may be said that when springs are utilized in parallel, their constants add up.
Do springs in parallel experience the same force?In springs the force must be the same. In parallel circuits the sum of all the currents going through each branch must be equal to the total current going into the branches. In parallel springs, the total force from all the springs must equal the total force from the mass.
When springs are connected in parallel the deflection for each spring is?2. Springs in Parallel: In parallel combination, force developed in each spring will be different but deflection in each spring will be equal.
