Air pressure is the weight of air molecules pressing down on the EARTH. The pressure of the air molecules changes as you move UPWARD from SEA LEVEL into the atmosphere. The highest pressure is at sea level where the DENSITY of the air molecules is the greatest. Measuring air pressure on island of Hawaii.

Energy is capacity of a physical system to do work . The common symbol for energy is the uppercase letter E . The standard unit is the joule , SYMBOLIZED by j . ONE joule is the energy resulting from the equivalent of one NEWTON of FORCE acting over one meter of displacement.plz mark it brainlist

since both of the VECTORS are perpendicular to each other therefore their dot product MUST be ZERO

SpeedExplanation:Because it KEEPS on CHANGING it's direction.. PLS MARK IT AS BRAINLIEST

tion:As an object approaches the SPEED of light, its mass rises PRECIPITOUSLY. If an object tries to travel 186,000 miles per second (299,792 kilometers per second), its mass BECOMES infinite, and so does the energy required to move it. For this reason, no NORMAL object can travel as FAST or faster than the speed of light.

A convex LENS or converging lens focuses the light rays to a specific POINT WHEREAS a concave lens or diverging lens diverges the light rays. A lens is a transparent material (EITHER curved or flat surface) based on the principles of REFRACTION.

riodThe TIME required by a BODY exhibitting periodic MOTION to complete one period is known as the time period. The S.I. unit is second. FREQUENCY : The number of times a body exhibits unique motion (each period) in one second is known as frequency.

The PROCESS of taking AIR into and expelling it from the lungs is called breathing. The action of breathing in and out is due to changes of pressure WITHIN the thorax, in comparison with the outside. ... When we inhale the intercostal muscles (between the RIBS) and DIAPHRAGM contract to expand the chest cavity

Amplitude, in physics, the maximum displacement or distance moved by a POINT on a vibrating BODY or wave MEASURED from its equilibrium position. It is EQUAL to one-half the length of the VIBRATION path.

y Here is your ANSWER Every ACTION has a EQUAL and opposite REACTION. Hope it help you Please mark me please #SIBI ❤️

having a LOT of LIGHT; very brightvery CLEVER, SKILFUL or successfulhope it will be HELP you

The word minimum simply MEANS the lowest Example-The minimum NUMBER of students in my CLASS is 30.please mark BRAINLIEST

(d) is the ANSWER of the

0then , total energy will be EQUAL to KEI HOPE it will helps U...☺️

in a back and fourth MOTION, it will be equal if LEFT undisturbed and if it is left undisturbed by external disturbances like external forces, air resistance ETC. They will be equal because of the law of consv. Of energy.

80.6FExplanation:

Perpendicular axes theorem : If I_x and I_y are the MOMENT of inertia about two perpendicular axes of any BODY the moment of inertia I about THIRD perpendicular AXIS is the sum of two moment of inertia.i.e. I_z = I_x + I_yParallel axes theorem : The moment of inertia I about an axis parallel to the axis through centre of mass C.M. is the sum of moment of inertia about C.M. and product of total mass M and SQUARE of perpendicular distance r between two axes concerned.i.e. I_CD = I_AB + M r²  where AB║ CD

the quantity of ROTATION of a body, which is the product of its moment of INERTIA and its ANGULAR VELOCITY.

A CAR GOING in REVERSE DIRECTION

the LAW of conservation of momentum STATES that for two OBJECTS COLLIDING in an isolated SYSTEM the total momentum before and after the collision is equal

n : Justify the statement that a uniform circular motion is an  accelerated motion.​Answer:In a uniform circular motion , the speed of the body remains same but the direction of motion changes at every point. In uniform circular motion different VELOCITY VECTOR at different positions of particle. At each position the velocity vector v is perpendicular to radius radius vector r.Hence velocity of body changes continuously DUE to continuous CHANGE in direction of motion of the body. As we know rate of change of velocity w.r.t. TIME is an acceleration.Therefore , uniform circular motion is an  accelerated motion.​

: A state in which NET torque is equal to zero. ... To achieve complete static equilibrium, a SYSTEM MUST have both rotational equilibrium (have a net torque of zero) and translational equilibrium (have a net FORCE of zero). translational equilibrium: A state in which net force is equal to zero.

heyExplanation:SINCE it is isothermal conditiontemperature REMAINS constant: ΔT =0which MEANS exchange of HEAT with the surroundings is constant

ar MOTION Pls MARK as the BRAINLIEST answer

tion:Pressure = Force÷Area = mass x acceleration ÷ length x breath = KG x m/s² ÷ m² = [M¹] x [L¹] ÷ [L²] [T²] = [L¹M¹] [L²T²] = [L-¹M¹T-²]If you are satisfy with my ans then MARK me as a BRAINLISTIF there is something wrong then kindly rectify it through LIVE chat at my question where GET know my mistakes in order to rectify it. Thank you

the ANSWER is in the above PICTURE

In one experiment, he USED two prisms to split a ray of white light into its colored components, and then put it back together into a ray of white light again. A simpler way to show how the different colors come together to make up white light is known as the Newton Disc.Newton's color DISK is a mechanical device that rotates an array of colors arranged as PETALS or gradients around an axis and when the disc rotates fast enough the perception of the color changes to white. This is because white light is nothing but the mixture of light of all wavelengths in the visible range.A Newton disc is a disc with segments in rainbow colours. When the disc is rotated, the colors fade to white; In this way ISAAC Newton demonstrated that white light is a combination of the seven different colours found in a rainbow. ... This property is based on the PRINCIPLES of dispersion of light.

Suppose 1 mole of gas is ENCLOSED in isothermal container. LET P1 ,V1 ,T be initial pressure, volumes and temperature. Let expand to volume V2 & pressure reduces to P2 & temperature REMAIN constant. Then, work done is GIVEN by

an ADIABATIC process is a thermodynamics process such that there is no heat TRANSFER in or out of the SYSTEM and is generally obtained by using a strong insulating MATERIAL SURROUNDING the entire system.please follow me and mark as brilliant

In an ADIABATIC process no EXCHANGE of heat between the system and surrounding are CALLED adiabatic process.
