A swimmer is capable of swimming 1.65 m/s in still water . If she swims directly across a 180m wide river whosecurrent is 0.85m/s ,how far downstream (from a point opposite her starting point) will she reach?

Answer»

hat,Speed of swimmer in STILL WATER is 1.65 m/sWidth of river is 180 mSpeed of river is 0.85 m/sTo find,How far downstream (from a POINT opposite her starting point) will she reach?SOLUTION,If t is the time taken by the swimmer to cross the river is calculated as :Let x is the distance from a point opposite her starting point. It is calculated by the PRODUCT of speed of river and time taken to cross the river.So, she will reach 92.65 m downstream.

1.Find the Reynolds number if a fluid of viscosity 0.4 Ns/m2 and relative density of 900 kg/m3 through a 20 mm pipe with a velocity of 2.5 m/s. Is the flow Laminar or Turbulent? Note: If Reynolds < 2000 the flow is laminar If Reynolds > 4000 the flow is turbulent If 2000 < Re < 4000 it is transitional flow Re = ρVL/η < 10^3 shows viscous force dominate. That is, viscous forces keep streamlines constant so they flow steadily over each other in predictable path. Re = Reynolds 2. At what temperature on the Fahrenheit scale will the temperature on a centigrade scale be three times that on a Fahrenheit scale?

A candle which is 2.5 cm in height is placed 27 cm in front of a concave mirror having radius of curvature 36 cm. Find the distance from the mirror at which the screen should be placed to obtain a sharp image? Detail the size and nature of the image. By how much the screen have to be moved if the candle is moved towards the mirror?​

Answer»

N :-Height of the candle, h =2.5 cmImage size=h’Object distance, u= -27 cmRadius of the concave mirror, R= -36 cmFocal length of the concave mirror, f = R/2 = -36/2= −18cm.Image distance= v=>1/v + 1/u = 1/f -------(Lens formula) =>.°. 1/v= 1/f- 1/u=>1/v = 1/-18 - 1/ -27=>1/v= -3 + 2/54=>1/v = -1/54.=> .°. v = -54cm.Therefore, to obtain a sharp image, the distance between the SCREEN and the mirror should be 54cm.Image magnification is:m = h'/h = - v/uh' = - v/u × h h' = -(-54)/ -27 × 2.5h' = -2 × 2.5h' = -5cm.5cm is the height of the image of the candle. As there is a negative sign, the image is inverted and virtual.If the candle is MOVED closer to the mirror, then the screen needs to be moved away from the mirror so as to obtain the image.

What is the function of Retina? Please give in point.​

Answer»

Explanation:The inner coat of the eyeball is called the RETINA. it contains the actual light receptors , the rods and the cones, and thus retina functions in the same way as the film of a camera does.Retina contains THREE layers of cells from inside to outside - ganglion cells, bipolar cells and photoreceptor cells. There are TWO types of photoreceptor cells ,namely rods and cones. these cells contain the light sensitive proteins called the photopigments.The retina consists of pigment epithelium(nonvisual PORTION) and a neural epithelium(visual portion).Retina contains blind spot, yellow spot (macula lutea) and FOVEA.Fovea is the point were the visual acuity (resolution) is highest and the vision is sharpest as fovea contains only cones.Retina is main area were light coming from object is perceived and transformed into electrical signals which reaches the visual cortex of brain through optic nerve.Image formed on the retina is recognised based on earlier memory and experience.

A heavy uniform plank of length L is supported by two force F, and F2 at points distant and from its ends as shown in the diagram. What is the ratio of F1 to Fz?plankEA) 2:5B) 3:5C) 5:8D) 2:3​

Answer»

D) 2:3Explanation:This is a torque problem. To BALANCE the plank, the counter clockwise torque must be equal to the clockwise torque. To simplify this problem, let’s ASSUME the length of the plank is 8 meters. The left support is 1 meter from its left end.L/4 = 2 metersThe right support is 2 meters from the right end. Let the pivot point be at the center of the plank. F1 is 3 meters from this point. F2 is 2 meters from this point.Counter clockwise torque = F2 * 2Clockwise torque = F1 * 3F1 * 3 = F2 * 2F1/F2 = 2/3Thanks!I HOPE it HELPS you.Good LucK!

Micah knows that a car had a change in velocity of 15 m/s. To determine acceleration, Micah also needs the of the total trip in seconds.

Answer»

To determine acceleration, Micah also needs the Time of the total trip in seconds.Explanation:Acceleration can be defined as RATE of CHANGE of velocity.a = dv/dtfor calculating acceleration, initial and final velocity are REQUIRED in meter per second and the total time of the trip in seconds. Then acceleration is measured in meter per second square.Thus, Micah knows that a CAR had a change in velocity of 15 m/s.To determine acceleration ,Micah also needs the TIME of the total trip in seconds.Thanks!I hope this makes sense.

A particle is projected at t = 0 from ground its velocity at t = 8sec is V = (15 i^ + 3 j^)m/s find out (A):- velocity at Max Height (B):- time of flight, range and maximum height​

Answer» VELOCITY = displacement / time and To find the time of flight, determine the time the projectile takes to reach MAXIMUM height. The time of flight is just double the maximum-height time. At maximum height, vy = 0. The time of flight is also determined SOLELY by the initial velocity in the y direction and the acceleration due to gravity. and for range use An object launched into projectile motion will have an initial LAUNCH angle anywhere from 0 to 90 degrees. The range of an object, given the initial launch angle and initial velocity is found with: R=v2isin2θig R = v i 2 SIN ⁡ 2 θ i g .the maximum height is given by u²/(2*g) .

Answer»

For soap solution.Periodically rub the brush against the SIDE of the NEEDLE so fresh bubble solution can continue to drip down the needle. With an eyedropper, slowly place colored water into the manometer. Because of the surface tension of the soap FILM, you will notice a higher pressure on the needle END of the manometer.2. Gravity stretches the stream, then surface tension pinches it into spheres. Flotation of objects denser than water occurs when the object is nonwettable and its weight is small ENOUGH to be borne by the forces arising from surface tension.
