Difference between the inter particle space and inter particle attraction​

Answer» INTERPARTICLE force of attraction can be define as the force of attraction EXERTS between PARTICLES(ATOMS,MOLECULES). And, Interparticle space can be define as the space between particles.for ex- In solid particles are very close so they interparticle space is very less while in gas particles are very far from each other so they interparticle space is large.Explanation:MARK AS BRAINLIEST

calculate the equivalent resistance between the two points A and B in the following circuit diagram.​

Answer» RESISTORS of 3Ω and 2Ω are also in series.∴ Their equivalent RESISTANCE, R 1 =3Ω+2ΩResistors of 6Ω and 4Ω are also in series.∴ Their equivalent resistance, R 2 =6Ω+4ΩNow, R 2 ,30Ω and R 2 are in parallel.Let R be the equivalent resistance.Then = R1 = R 1 1 + 301 + R 2 1 = 51 + 301 + 101 = 306+1+3 = 3010 orR= 1030 =3Ω Hence, the equivalent resistance between A and B is 3Ω.

Explain the following : a) 1. Dust particles are removed from a carpet by beating it. 2 .It is advantageous to run before taking a long jump. ​

Answer»

hanging carpet is beaten with a stick, the dust particles are removed from it because the carpet on beating SUDDENLY moves forward and the dust particles DUE to inertia of rest continue to remain at rest. Hence the dust particles fall down and the carpet gets cleaned.An athlete runs before jumping to gain momentum. Because it helps in jumping higher and longer because of inertia of motion gained due to the motion. When the athletes Jump they already have a forward motion that would be greater than that of a jump made from STANDING in ONE SPOT.

" A light ray passing through the focal point of a concave mirror reflected fromthe minor. Draw the reflected day.​

Answer»

because if a tangent is drawn at the point of CONTACT of the mirror where the ray PASSES through the curvature and touches the mirror, then it would be 90 degrees since the radius of curvature is perpendicular to the tangent hence the angle of INCIDENCE will coincide with the NORMAL. Therefore angle of reflection will also coincide and hence it passes again through the center of CutrulaI HOPE IT'S HELP U PLEASE MARK ME BRAINLEST AND FOLLOW ME ⚡FASTER

Derive the equation to determine the coordinates for Q point in voltage divider bias circuit ​

Answer»

About North Star High VoltageNorth Star High Voltage develops and manufactures high voltage probes which define the state of the art in high voltage measurements. We also develop and manufacture support CIRCUITS for closing tubes including Thyratrons and Ignitrons (Thyratron drivers and Ignitron drivers).North Star builds two main types of high voltage probes – the PVM SERIES designed for portability, and wide bandwidth, and the free standing VD series designed for long life and accuracy. Both types of probes can be used with 1 Megohm INPUT oscilloscopes (standard) or with METERS of various input impedances (specify meter type when ORDERING). The probes are also available in “bare” versions for OEM applications.

Velocity time graph of a 50 gram marble rolling on floor in given below find- 1. time in which it stops2. negative acceleration produced on it.3. positive force acting on the marble​​

Answer»

1. Time is 25 seconds2. Negative acceleration is 1.2 m/s²3. Positive FORCE is 60NExplanation:2. INITIAL velocity, u=30m/sFinal velocity=0 m/sTime, t=25sUsing the FIRST equation of motion,Acceleration =(v-u)/t= (0-30)/25 = -1.2 m/s²3. If mass of the MARBLE is 50g, force can be CALCULATED usingF=ma = -1.2×50=-60N
