Statics

No, a blow dryer does not produce static electricity. Static electricity is generated when two objects rub against each other, creating a charge imbalance. A blow dryer simply dries hair using heated air.

cyclical variation: Piece to piece variation. Often used to describe a repeating pattern, such as a seasonal variation in sales that peaks before Christmas.

All energy ultimately ends up as heat, thus, all physical processes' ultimate 'waste' products is heat Friction always creates heat, and an increase in friction always creates an increase in (waste) heat...remember Second Law of Thermodynamics, right? Thus: Friction increase increases heat; increases waste and thereby decreases efficiency, without even considering the damage that the increased heat can create

Since volume is an extensive property, there is no particular constant associated with it - indeed, by virtue of being an extensive property, it is not constant unless the mass, temperature, pressure, phase, and composition remain constant.

There are, of course, conversion factors between different volume units - and the conversion factors are constants.

The angle of shear is the angle between the shear plane and the direction perpendicular to the normal stress in a material under shear stress. It represents the amount of deformation occurring due to shear forces acting on the material.

i am doing this experiment to find the surface tension. as i am using silicone oil and water. the needle is dipped in the water and produced silicone bubble and took images. i found the angle but i don't know which equation to use. please if anyone can help me out with the equation. thanks

The atmosphere exerts a pressure of about 10,000 kg/m^2 at sea level. This pressure is equivalent to the weight of the air above a unit area, so the mass of the atmosphere per square meter can be approximated as 10,000 kg.

Courses in data science, software development, digital marketing, finance and accounting, and healthcare (especially nursing and pharmacy) are currently considered marketable in Kenya. These fields are in high demand and offer good job opportunities and competitive salaries.

It would take approximately 420 feet for an 80,000-pound tractor-trailer traveling at 50 miles per hour to come to a complete stop under ideal conditions. However, various factors such as road conditions, weather, and driver reaction time can affect the stopping distance.

If the ropes are perfectly vertical AND both of them are indeed sharing the load,

then the tension in each rope is 5N. But it would be practically impossible to have

them exactly share the load, and one would wind up supporting most or all of it.

The best way to make them share is to use elastic ropes, like bungees. They still

would never share equally, but at least they would share. In any case, the

tensions in both support strands would always add up to 10N.

The sciatic nerve is formed by several nerve roots exiting the lower spine, specifically from the L4 to S3 segments of the spinal cord. These nerve roots then come together to form the largest nerve in the body, the sciatic nerve, which runs from the lower back down through the buttocks and into the legs.

Generally no. The friction force is typically assumed independent of surface area, and proportional to the force between the two objects. By changing the contact area, you are changing how that force is concentrated. i.e. a small surface area means that your force is distributed across a small region, creating a high pressure (force/area) at the contact. By increasing the surface area, you distrubte that force and lower the pressure.

This is, however, an idealization and can break down in some instances.

No work is taking place and no energy is moving outside of your body.

The movement of energy is all in your muscles, and it gets dissipated

as the sweat trickles out of your skin and evaporates into the air.

As the plane hits the deck, its kinetic energy is 1/2 (its mass) x (its speed)2,

so that's the amount of energy that has to go somewhere in order to bring

the plane to a complete stop where its kinetic energy is zero.

My guess at the moment is that the energy must be dissipated in one humongous

shock-absorber at each end of the cable. Springs don't dissipate the energy ...

they only store it, and then it still has to go somewhere. Shocks dissipate it.

No, because the amount of force you have applied to the rock cancels with the reaction force from the rock pushing back. Action- reaction. Think about the different types of energy you need to consider:

½mv²

mgh

and possibly rotational ½iω²

Have you given the rock any of these things? If not then there has been no transfer of energy, save possibly the heat from your hands

No, knots rely on friction to hold them in place, so without friction, knots wouldn't be effective in securing items.

Approx. 20% of the population lives in the Greater Copenhagen area, which located on the eastern edge of the island of Zealand ('Sjælland' in danish, originally meaning 'Seal Island'). While it's not that unusual for a country to have such a large part of the population living in the capital area, it is usual to have a Capital at the outer rim. This is due to the fact that until 1658 this location was centrally located in the country.

To calculate the force required to pull the 5000kg pipe along the 10 sets of idle pipe conveyor systems, you need to consider the frictional force acting against the movement of the pipe. This frictional force will depend on the coefficient of friction between the pipe and the conveyor systems. You can use the formula F_friction = coefficient of friction * Normal force to calculate the force required. The force needed to overcome this frictional force should be less than the total normal force acting on the pipe.

Statics in economics focuses on analyzing economic variables at a specific point in time, while dynamics looks at how these variables change over time. Static analysis typically examines equilibrium conditions, while dynamic analysis considers how variables evolve over different time periods.

The amount of horizontal force required to start in motion an object sitting on a horizontal surface must be greater than the force of static friction acting on the object. This is because the force of static friction opposes the applied force until the object starts moving.

When adding vectors using the head-to-tail method, you place the head of the second vector at the tail of the first vector. The resultant vector is drawn from the tail of the first vector to the head of the second vector. This technique preserves both magnitude and direction of the vectors being added.

Pressing your palms against a wall with full force is an isometric exercise, where you engage your muscles to generate tension without joint movement. This activity can help strengthen your arms, shoulders, and chest muscles.

Sliding friction occurs when two surfaces slide against each other, creating resistance and frictional force that opposes the motion.

Engine bounce is a phenomenon where the engine speed rises rapidly and then drops back down while the vehicle is idling. This can be caused by issues with the fuel system, ignition system, or engine timing. It can lead to rough idling and poor engine performance.

The formula for load, also known as total force acting on the airplane, is calculated by multiplying the acceleration due to gravity (g) by the weight of the airplane (w). This formula helps in understanding the stress and strain on the airplane during flight due to the influence of gravity.
