A force acts on a mass of 16 g for 3 s and then ceases to act. What the magnitude of the force?​

Answer»

144 dynExplanation:While covering the distance of 81 cm, there was no external force on the body and therefore it must have covered this distance with a uniform VELOCITY v, generated when the force was acting on the body.s = vt or, v = `(s)/(t) = (81)/(3) = 27 " cm " cdot s^(-1)`If the acceleration on the body due to force was a then`" "` v = u + at or, 27 = 0 + a`xx`3 or, a = 9 cm `cdot s^(-2)``therefore" "` Applied force, F = ma = 16 `xx` 9 = 144 dyn.hope it is helpful to you mark as BRAINLIEST ...

C) Draw a diagram and explain in detail the parts of a UV-Visible Spectroscopy.​

Answer»

A diagram of the components of a TYPICAL spectrometer are shown in the following diagram. The functioning of this instrument is relatively straightforward. A beam of light from a VISIBLE and/or UV light source (colored red) is SEPARATED into its component wavelengths by a prism or diffraction grating. Each monochromatic (single wavelength) beam in turn is split into two equal intensity beams by a half-mirrored device. One beam, the sample beam (colored magenta), passes through a small transparent container (cuvette) containing a solution of the COMPOUND being studied in a transparent solvent. The other beam, the reference (colored blue), passes through an identical cuvette containing only the solvent. The intensities of these light beams are then measured by electronic detectors and compared. The intensity of the reference beam, which should have suffered little or no light absorption, is defined as I0. The intensity of the sample beam is defined as I. Over a short period of time, the spectrometer automatically scans all the component wavelengths in the manner described. The ULTRAVIOLET (UV) region scanned is normally from 200 to 400 nm, and the visible portion is from 400 to 800 nm.

A circular coil of radius R and N turns has negligible resistance. As shown in the schematic figure, its two ends are connected to two wires and it is hanging by those wires with its plane being vertical. The wires are connected to a capacitor with charge Q through a switch. The coil is in a horizontal uniform magnetic field Bo parallel to the plane of the coil. When the switch is closed, the capacitor gets discharged through the coil in a very short time. By the time the capacitor is discharged fully, magnitude of the angular momentum gained by the coil will be (assume that the discharge time is so short that the coil has hardly rotated during this time) ​if you gave the correct solution then I will mark you as brainliest answer

Answer»

- Radius of COIL = R Number of turns = N Charge on capacitor = Q MAGNETIC field = B⁰As we know that,τ = M × B τ = NiAB⁰τ = iπR²NB⁰There is a RELATION between torque and angular momentum,τ = dL/dtdL = τdtdL = iπR²NB⁰ dtdL = πQR²NB⁰ ( idt = Q) Hence,Angular Momentum = dL = πQR²NB⁰

Q1-Answer the following question 1-The density of a substance is maximum in its solid states.intermediate in its liquid states and minimum in its gaseous state.Explain2-Which two forces act on the object when it is immersed in a liquid? How does their magnitude determine that the object will float or sink in the liquid?​​Guys help me tomorrow is my exam​

Answer»

1) it is so because in SOLID state the molecules of that SUBSTANCE are tightly packed together while in liquid state they are slightly far apart and in gaseous state they are very far apart making the substance LESSER dense.Explanation:2) first is the gravitational force or WEIGHT of the object and the SECOND is the upthrust. if the weight of the object is more than the uphrust then it will sink otherwise it will float.

Q1-Give reason of the following: 1-Icebergs floating in sea water are dangerous ships.2-A submarine can float like an ordinary ship and sink when required. 3-A balloon filled with hydrogen or helium rises in the air.4-An iron nail sinks in water but a huge ship made of iron and steel floats in water.​

Answer»

answer 1 - ice bergs floating in sea water are dangerous for ships because when they come in contact together the harm goes to ships which can made them sink also.answer 2 - a submarine can float like an ORDINARY ship and sink when required because when the tanks are EMPTY the submarine has less mass and it floats like and ordinary ship but when the water is ALLOWED into the tanks the mass increases then they sink into the wateranswer 3 - a ballon filled with hydrogen or helium rises in the AIR because these GASES are very light weighted that make the ballon rises up.answer 4 - the iron nails sink in water but a huge ship made of iron and steel doesn't sink in the water because the bottom of the ship is designed as to float in water which doesn't happens with iron nails
