In physics and engineering, a free frame diagram (FBD; also referred to as a force diagram) is a graphical instance used to visualize the applied forces, moments, and ensuing reactions on a frame in a given situation.
A free-body diagram is a sketch of an item of interest with all the surrounding items stripped away and all of the forces acting on the frame shown. The drawing of an unfastened-body diagram is a critical step in the solving of mechanics issues because it helps to visualize all the forces appearing on an unmarried object.
A free-body diagram is a graphic, dematerialized, symbolic representation of the body (structure, element, or segment of an element) wherein all connecting "pieces" have been removed. An FBD is a convenient method to model the structure, structural detail, or phase that is under scrutiny.

Energy is the quantitative attribute that is transferred to a body or to a physical system. It is recognized in the execution of work as well as in the form of heat and light (from the Ancient Greek: v, enérgeia, "activity"). Energy can be transformed in form but cannot be created or destroyed, according to the rule of conservation of energy. The joule is the SI's (International System of Units) unit of measurement for energy.
A moving object's kinetic energy, a potential energy stored by an object (for instance because of its position in a field), the elastic energy contained in a solid object, chemical energy linked to chemical reactions, radiant energy carried by electromagnetic radiation, and internal energy contained within a thermodynamic system are examples of common forms of energy. Energy is continuously taken in and released by all living things.
Any item that has mass when it is motionless (referred to as rest mass) also has an equivalent amount of energy, known as rest energy. As a result, any additional energy (of any type) that the object acquires above that rest energy will increase the object's total mass as well as its total energy.

What type of energy does the pendulum have when it is hanging straight down?; At which position of a pendulum kinetic energy is maximum?; What point in the pendulum is the potential energy maximum?; Where in the pendulum swings path is the kinetic energy the greatest Where is the potential energy the greatest?
Kinetic energy is the energy that the pendulum have when it is hanging straight down and at the lowest point pendulum is the potential and kinetic energy is maximum.
A simple pendulum consists of a small mass suspended on an approximately massless, non-stretchable string. It is free to oscillate from side to side. The forces acting on the mass are the force of gravity and the tension in the string.
The tension cancels out the component of mg that lies along the string; this keeps the object from accelerating in the direction of the string, and thus keeps the string's length constant.
The net force is simply the remaining component of mg, which is pointed perpendicular to the string and is equal to Fnet=-mgsinФ
The pendulum only has gravitational potential energy, as gravity is the only force that does any work. The total energy of the pendulum is the potential energy at the maximum displacement, when the displacement is equal to the amplitude is 1/2mgLA^2.

Why does the sound of something moving away from you seem to change to a lower and lower pitch?; What happens when two sound waves meet in constructive interference apex?; In what way are all sound waves and light waves similar?; How is the amplitude of waves affected by destructive interference?
The given situation is because of the phenomena of Doppler's Effect.
How does the sound gets faint ?You may have observed that the pitch of a siren decreases sharply as it passes you at a high rate of speed. When the pitch is higher, the siren first approaches you. The siren is moving away from you and becomes quieter once it has passed you. The Doppler effect is manifested in this way.
The region that the sound waves cover grows as one gets farther from the source of the sound. The intensity and loudness of the sound are reduced because the same quantity of energy is dispersed over a larger region. This explains why, as you get further away from the source, even strong noises start to diminish.

The horizontal component of a force represents the part of the force which acts in the horizontal direction with respect to the body.
What is horizontal component and vertical components?The horizontal velocity component (vx) describes the influence of the velocity in displacing the projectile horizontally. The vertical velocity component (vy) describes the influence of the velocity in displacing the projectile vertically.Given the data in the question;The horizontal velocity of a projectile is constant (a never changing in value), There is a vertical acceleration caused by gravity; its value is 9.8 m/s/s, down, The vertical velocity of a projectile changes by 9.8 m/s each second, The horizontal motion of a projectile is independent of its vertical motion.Vectors are mathematical representations that are directed and magnitude-based. The direction of a vector in a two-dimensional coordinate system is determined by the angle it makes with the positive x-axis. Here, vector V is split into two components: vx and vy. Vx is known as the Horizontal Component of the vector V.
The intensity is proportional to the electric field amplitude;
now, we assign the electric field of 1 to the vertical component and an electric field of 2.8 to the horizontal component
so;
Horizontal intensity = 1² = 1
Vertical intensity = 2.8² = 7.84
so total intensity = 1 + 7.84 = 8.84
fraction of the light intensity received before the glasses were put on now reaches the sunbather's eyes,
since the sunglasses blocks the horizontal intensity so only the the vertical intensity goes through;

Here, water activity in "Water-in-salt" electrolytes (WiSE) based on potassium acetate (KAc) is investigated using Raman and classical molecular dynamics (MD), demonstrating the significantly reduced water activity of these WiSEs because water can be efficiently coordinated by both the acetate anion and the potassium cation. It is discovered that the overall molecular arrangement resembles the "sponge-like" shape seen in several ionic liquids. According to comprehensive electrochemical, scanning electronic microscopy (SEM), and X-ray photoelectron spectroscopy (XPS) study, such WiSE can also be compatible with Al current collectors with appropriately adjusted composition.

What is the net force on skydiver falling?; What is the net force on a skydiver falling with a constant velocity of 10 m/s downward?; What happens when a skydiver jumps?; What's the highest someone has skydived?
If his velocity remains constant, there will be no net force acting on him since any force acting on him will be precisely cancelled out by a force acting in the opposite direction.
What is the net force that causes skydivers to fall?The falling skydiver experiences an upward push and acceleration. If an object is falling downward and there is an upward net force acting on it, the object will slow down. The skydiver slows down as a result. Once more, the skydiver approaches a terminal velocity as the air resistance diminishes along with the speed.
What is a skydiver's net force when they reach their terminal velocity?ZERO When an object reaches its terminal velocity, the upward force from air resistance and the force of gravity are equal.

250 students sit in an auditorium listening to a physics lecture. because they are thinking hard, each is using 125 w of metabolic power, slightly more than they would use at rest. an air conditioner with a cop of 7.5 is being used to keep the room at a constant temperature. What minimum electric power must be used to operate the air conditioner?
The minimum electric power that must be used to operate the air conditioner is 6250 W.
The total students in the auditorium are n = 250
The metabolic power each student is using is p = 125 W
The coefficient of performance ( COP ) of the air conditioner is given as 5 to maintain a constant temperature inside the auditorium.
Let the minimum electric power that must b used to run the air conditioner be P.
We know that
COP = np / P
P = np / COP
= ( 250x 125 ) / 5
= 6250W
So, 6250 W power is the minimum power.
