Formation of shadow on a glass sheet

Answer»

Formation of ShadowsShadows are ALWAYS FORMED on the opposite side. Transparent OBJECTS cannot form a shadow. They are only formed in opaque or translucent objects. If we take a glass SLAB, no shadow is formed because it ALLOWS light to pass through it.Explanation:This may help you ☺️Thank you

Fringes are formed by a Fresnel’s bi-prism in the focal plane of a reading microscope, which is 100 cm from the slit. A lens inserted between the biprism and the microscope gives two images of the slit in two positions. In one case the two images of the slit are 4.050 mm and in other, they are 2.900 mm apart. If the sodium light (λ=589.3 nm) is used, find the distance between the interference fringes.

A flower pot falls off a window sill and falls past the window below. It takes 0.30s to pass a window 3.45 m high. How far is the top of the window below upper window sill?​

Answer»

ime = t = 0.30 sDistance = S =3.45 mTo find:h =?Explanation:Let h be the height window sill from the ground.An object is following down from the window.∴ a = g =9.81Now, the object is following down from 3.45 m HIGH from the ground.By using the THIRD law of kinematical EQUATIONS = ut + 3.45 = u (0.30) + 0.5 × 9.81  ×0.30  × 0.30u = 25.8924∴ u = 25.89 m\sNow consider the object is following down from the window sill.v = 0 , s = h = ?By the third law of kinematics:0 = 25.89 × 25.89 + 2 × 9.81 × HH = -34.16 mA negative sign shows that object is following down to the ground.∴ h = 34.16 mA window sill is 34.16 m high from the ground.

Equations of motion in vector notation.

Answer» SINCE the equality of two vectors implies equality of their COMPONENTS, those two equations are equivalent to v x = ˙ x , a x = ˙ v x = ¨ x and similar equations for the y and Z components. Therefore, a motion in three dimensions is always the superposition of three one-dimensional MOTIONS along the x , y and z axis.Explanation:here your ANSWER hope it will help you

Solid liquidGasPropertyshapeRicedvolumecompress-iblityDiffusion.​

Answer»

id stateSolids keep their shape and cannot be compressed. Let us see if the particle model can help us understand why solids behave in this way.In a solid, the particles are packed close to each other in fixed positions. They are locked into place, and this explains why solids have a fixed shape. Look at the following images of sodium chloride (table salt). Do you remember the formula for sodium chloride?The liquid stateAn important characteristic of liquids is that they flow. They fill containers they are poured into. Liquids are also not very compressible. How can these properties be explained?Orange juice is a liquid, which can be poured.In the liquid state, particles do not have fixed positions. They move about freely, but they stay close together because the forces of attraction between them are quite strong, but not as strong as in solids.Have you noticed how a liquid always takes the shape of the container it is in? Within the liquid, the particles slip and slide past each other. This is why liquid flows. Their particles are free to move around, filling the spaces left by other particles. Look at the image of the juice being poured. Let's zoom in and have a look at what the particles are doing as the juice is poured.The particles in a liquid have small spaces between them, but not as small as in solids. The particles in a liquid are loosely arranged which means they do not have a fixed shape LIKE solids, but they rather take the shape of the container they are in.The speed at which the particles move around inside the liquid depends on the energy of the particles. When we heat a liquid, we are giving the particles more energy and speeding them up.In gases, the particles move at even greater speeds.The gaseous stateGases spread out quickly to fill all the space available to them. Think of when you blow up a balloon. The air that you blow into the balloon FILLS up the whole balloon. A gas will fill the entire space that is available to it. This is because the particles in a gas have no particular arrangement.Gases do not have a fixed shape. Think about the balloon again: the gas fills the entire space inside the balloon. You can squeeze the balloon, changing the shape.Gases fill the space available to them.Gases do not have a fixed shape.Gas particles move very fast, much faster than in solids and liquids. The particles in a gas possess a lot of energy.Have you ever TRIED to compress the gas in a syringe or in a bicycle pump? Why do you think you can compress the gas?In gases, the forces between particles are very weak. This explains why the particles in gases are not neatly arranged. They are not held together tightly and there are large spaces between them. These spaces are much larger than in the solid and liquid state.Gases can be compressed, because their particles can be forced closer together. Look at the photo of a SCUBA diver underwater. Do you see the tank on his back? He uses this tank to breathe underwater. A scuba diver can stay underwater for almost an hour. How do you think he can GET enough air to breathe for a whole hour from a small tank like that? Discuss this with your class.

A cricket ball of mass 100g moving at a speed of 20m/s is brought to rest in 3s. Find the average force applied by the player

Answer»

mass of the ball (m) =100g or 0.1kginitial velocity (U) =25 SM time (t) = 0.025sec.final velocity (v) = 0Initial momentum = mu = 0.1×25 = 2.5 skgm Final momentum = mv (which is equal to 0, since v is zero)CHANGE in momentum = mv-mu = 0 - 2.5 = -2.5 skgm Average force = timeChangeinmomentum = - 0.025(2.5) = -100 skgm = -100 NThe NEGATIVE sign actually shows that the force was applied opposite to the direction of the motion of the ball. So, the average force applied by the player will be 100

What is quantization of charge?​

Answer»

Explanation:Quantization of charge implies that charge can assume only certain DISCRETE values. That is to SAY the observed VALUE of electric charge (q) of a particle will be integral MULTIPLES of (e) 1.6×10−19 coulombs.i.e.q=ne where n=0,1,2,.... (both positive and negative integers)The charge cannot assume any value between the integers.
