(i) GRAVITATIONAL FORCE is a NON CONTACT force

if the object vibrates 30 times in 2 min, then it vibrates 15 times in 1 min.Then we divide 15 by 60(seconds), which GIVES us 0.25, and this is our frequency.Obs: We divide 15 by 60 because frequency means how many PERIODS in ONE second, and 1 minute have 60 seconds, and then, that’s why we divide by 60.Similarly, if you want to know the period, you divide 1/frequency , because frequency is the inverse of period, which gives us 4, and this means that 1 VIBRATION takes 4 seconds.

To express this concept mathematically, the work W is equal to the force F TIMES the distance d, or W = FD. If the force is being exerted at an angle θ to the DISPLACEMENT, the work done is W = fd cos θ

AUParsecs: Many ASTRONOMERS PREFER to use parsecs (abbreviated pc) to measure distance to stars. This is because its definition is closely related to a method of measuring the distances between stars. A parsec is the distance at which 1 AU SUBTENDS an ANGLE of 1 arcsec.HOPE IT WILL HELP YOU

tion:Various techniques are used for the ENHANCEMENT of the solubility of poorly SOLUBLE DRUGS which INCLUDE physical and chemical modifications of drug and other methods like particle size reduction, crystal engineering, salt formation, solid dispersion, use of SURFACTANT, complexation, and so forth.

Question :A trolley of mass 200 kg carrying a sandbag of 10 kg is moving uniformly with a SPEED of 27 km/hr on a frictionless track. After a while, SAND starts leaking out of a hole on the floor of the trolley at the rate of 0.05 kg/second. What is the speed of the trolley after the entire sandbag is empty?Given :Mass of the trolley = 200 kgMass of the sand bag = 10 kgInitial velocity = 27 km/hrTo Find :Final velocity of trolley when total the entire sand bag is emptySolution :❖ Since no external horizontal force ACTS on the whole system, linear MOMENTUM is conserved throughout the motion.We know that it is measured as the product of mass and velocity.Initial momentum (p) = (M + m) uFinal momentum (p') = M v [∵ m = 0]» M denotes mass of trolley» m denotes mass of sand bagInitial velocity = 27 km/hr = 7.5 m/sBy substituting the given values;➙ (M + m) u = M v➙ (200 + 10) × 7.5 = 200 v➙ 210 × 7.5 = 200 v➙ v = 1575/200➙ v = 7.88 m/s

Magnetic forces are NON contact forces; they pull or push on objects without touching them. ... The force of GRAVITY is another example. THUS, gravity will pull a raindrop down to Earth without any tangible physical LINK between the Earth and the drop.Explanation:

he MAIN parts and their functions are:1. Ratched - advance the screw by turning it till the OBJECT to be measured in held gently in between the spindle of the screw and the stud.2. Sleeve - it notes the base line and the base LINE3. Thimble - circular SCALE is marked by the thimble4. Circular scale - reads length correctly to 0.01 mm5. Main scale - reads length to 1 mm.

n 9. Is it possible for an atom of an element to have one electron, one proton and two neutrons? If so, name the element.​Answer:  In case of HYDROGEN isotope deuterium EXPLANATION Isotopes are VARIANTS of a PARTICULAR CHEMICAL element which differ in neutron number, and consequently in nucleon number.

tion:Here, KE is KINETIC energy,L is ANGULAR momentum,w is angular FREQUENCY,I is MOMENT of inertia

cell: A primary cell or BATTERY is the ONE that cannot EASILY be recharged after one use, and are DISCARDED following discharge. Secondary cell: A secondary cell or battery is one that can be electrically recharged after its complete discharge.

tion:Answer. THEREFORE, a body would take 8sec to gain velocity of 24m/s if a FORCE of 30N acts on it.

tion:The HEAT generated is approximately equal to h=i^2*R*tHere I= 5AR=12 ohmt= 60 secSo h=25*12*60 =18000 joule =18 kJoule

E= Kv²K=E/v²E=Energy JOULE(J) = kg m²/s²v= Velocity v² = m²/s²Therefore, K = kg m²/s² m²/s² K = kgSo, dimensions of K = [M¹ L⁰ T⁰]

yesExplanation:HYDROGEN is the ELEMENT

the relationship between the CGS and SI unit of density​. SI unit of Density = 1000 CGS unit of Density = CONVERTING to SI unit - = kg/m³ = 1000 ∴ The relation between SI unit of Denity and CGS unit of Density is ⇒ = 1000 ✭ NOTE -Comparing the values and KNOWING the conversion table will help you in making out the relation better.Hope this HELPS uh! ♡

Distinguish between streamline and turbulent flow of a liquid. ... iii) The velocity of streamline flow is LESS than critical velocity but, in turbulent motion the liquid MOVES with a velocity GREATER than the critical velocity of the liquid. IV) Streamline flow is laminar whereas, turbulent flow is non-laminar.

on✯Relationship between WAVELENGTH , wave velocity , frequency.✬Answer✬Let velocity of a wave be V , TIME period be T , frequency be f and wavelength be λ.Wavelength (λ) = Distance travelled by the wave in ONE time period Wavelength (λ) = Wave velocity × Time periodWavelength (λ) = V × TVT = λBut , we know , T = 1 ÷ fT is time period , f id frequency.So, V × 1 ÷ f = λ V = fλ➺Wave velocity  = Frequency × Wavelength  (V = fλ)

The obejective of a telescope must have large aperture to gather more light. It should ALSO have large focal LENGTH. Therefore, lensis selected as objective lens.
The eye piece should have small aperture and small focal length. Therefore, lensis selected as eye lens. In normal ADJUSTMENT, Magnifying.

Mark me as brianlistExplanation:Why a loaded SHIP is more submerged while an UNLOADED ship is less submerged. This is because when a body is immersed in a liquid, the following two forces act on it : ... The upthrust is equal in magnitude to the weight of liquid DISPLACED. This force has a TENDENCY to make the body float

Livestock Ranching Livestock is believed to be responsible for about 14% of global deforestation. Farmers OFTEN clear the land by cutting down trees and BURNING them to raise livestock and grow food.

In the first law, an object will not change its MOTION unless a force acts on it. In the second law, the force on an object is equal to its mass times its acceleration. In the third law, when two objects INTERACT, they APPLY forces to each other of equal MAGNITUDE and OPPOSITE direction.

The DOPING of SemiconductorsPentavalent impurities IMPURITY atoms with 5 valence electrons produce n-type semiconductors by contributing extra electrons. Trivalent impurities Impurity atoms with 3 valence electrons produce p-type semiconductors by producing a "hole" or ELECTRON DEFICIENCY.
