Isostasy is the rising or settling of a portion of the Earth’s lithosphere that occurs when weight is removed or added in order to maintain equilibrium between buoyancy forces that push the lithosphere upward and gravity forces that pull the lithosphere downward. What is isostasy example? Geologic Examples of Isostasy An iceberg floating on the…

When there is current present in the device or the electrical circuit and there’s a voltage drop in source voltage or source battery is internal resistance. It is caused due to electrolytic material in batteries or other voltage sources. What is internal resistance in physics? Internal resistance refers to the opposition to the flow of…

Flexibility. Flexibility is extending and contracting the muscle tissues, joints, and ligaments into a greater range of motion accepted by the nervous system. Mobility. Strength. Power. Endurance. Stability. What are the 5 primary terms of motion? Any object that moves from one point to another is considered in motion. Motion is described using different descriptors…

The trapped air currents can create an air cushion on any smooth surface, land or water! The cushion greatly reduces friction, allowing the vehicle to glide freely over the smooth surface below. How does a hovercraft work physics? A hovercraft has what’s called a skirt to contain the air. When the air blower is turned…

The force of hydrostatic pressure means that as blood moves along the capillary, fluid moves out through its pores and into the interstitial space. This movement means that the pressure exerted by the blood will become lower, as the blood moves along the capillary, from the arterial to the venous end. What is hydrostatic pressure…

Gears are used to transfer motion and torque between machine components in mechanical devices. Depending on the design and construction of the gear pair employed, gears can change the direction of movement and/or increase the output speed or torque. What are gears easy definition? A gear is a simple, rotating machine which usually has teeth…

/ˈɡæm.ə ˌpɑː.tɪ.kəl/ a photon (= a unit of light) that is produced in gamma radiation (= a type of radiation with a very short wavelength that passes through most solid objects) What is gamma in quantum physics? The newly defined function γ(x) serves to describe quasi-classical particles using part of the quantum formalism (eg, wave…

Spilling. Dropping equipment. Not cleaning equipment. Ignoring directions. Writing an incorrect number. Hitting the wrong key on a calculator. Not paying attention to units/labels. What are experimental errors called? Revised on August 19, 2022. In scientific research, measurement error is the difference between an observed value and the true value of something. It’s also called…

Solution : An energy chain is a way of showing how energy is converted from one form to another. Originally, all energy comes from the Sun on the Earth. This energy is transformed into different forms and thus, used for various purposes. Examples are : Solar energy and wind energy. Answer. What is an energy…

direction in which energy of wave is moving. What is direction of propagation in physics? The direction of propagation of the electromagnetic wave always tends to be perpendicular to the plane in which the electric field (E) and magnetic field(B) lie. Thus, the direction of propagation of the electromagnetic wave can be given as: E…

“V” with one dotted and one solid over it = DC voltage. “mV” with one wavy line or a pair of lines, one dotted and one solid, over it = AC or DC millivolts. What are direct circuits? DIRECT CURRENT or DC is similar to the normal flow of water in a hose – it…

In fluid dynamics, the Nusselt number (Nu) is the ratio of convective to conductive heat transfer at a boundary in a fluid. Convection includes both advection (fluid motion) and diffusion (conduction). What is Nu in modern physics? The frequency of a wave in physics and other fields; sometimes also spatial frequency; wavenumber. What does μ…

W = F.Δx. In the case of a variable force, work is calculated with the help of integration. For example, in the case of a spring, the force acting upon any object attached to a horizontal spring can be given as: Fs = -kx. How do you calculate work when force varies? You can write…

The volume of a gas, solid or liquid changes if the temperature, the pressure or the forces acting on that gas/solid/liquid change. In the case of thermal analysis, we are looking at temperature-dependent changes. What is the unit of volume expansion? oefficient of real expansion: It is the true increase in the volume of liquid…

velocity ratio is The ratio of the distance moved by the point at which the effort is applied in a simple machine to the distance moved by the point at which the load is applied, in the same time. In the case of an ideal (frictionless and weightless) machine, velocity ratio = mechanical advantage. What…

The word erect means upright or straight. Hence, an image formed by a mirror or a lens is said to be an erect image if it is upright, ie, not inverted. For example, image formed by a plane mirror is always erect. What is a virtual and upright image? Virtual image refers to the image…

As a parallel resonance circuit only functions on resonant frequency, this type of circuit is also known as an Rejecter Circuit because at resonance, the impedance of the circuit is at its maximum thereby suppressing or rejecting the current whose frequency is equal to its resonant frequency. What is resonance circuit explain in brief? Series…

A statistical distribution in which the variates occur with probabilities asymptoticallyasymptoticallyInformally, the term asymptotic means approaching a value or curve arbitrarily closely (i.e., as some sort of limit is taken). A line or curve that is asymptotic to given curve is called the asymptote of . More formally, let be a continuous variable tending to…

: change of phase of an oscillation or a wave train. What is called phase in physics? Any sine wave that does not pass through zero at t = 0 has a phase shift. The difference or phase shift as it is also called of a Sinusoidal Waveform is the angle Φ (Greek letter Phi),…

The formula for Linear Acceleration: Its unit is meter per second squared or m s^-2. If t (time is taken), v (final velocity) and u (initial velocity) are provided. Then the acceleration formula: v = u+at. v² = u² + 2as. What is linear acceleration example? Linear acceleration. The rate of change of velocity without…
