    Physics, Chemistry and Biology: Post your doubts here!

    it's virtual since it cannot be projected on a screen since it is just like you are using a mirror. it is formed by the total internal reflection of two glass prisms...each glass prism has a critical angle of 42 degrees and all light rays hit its surface at 45 degrees so it is reflected by 45...

    Physics: help me please :cry:

    no if the speed increases the acceleration wont increase...it will be constant......if the speed decreases the decceleration wont decrease..it will be contant. magnitude is a unit or number such as 40 kg is a mass and 40 is the number or 37 m/s...37 is the magnitude

    Physics, Chemistry and Biology: Post your doubts here!

    6 b)(i) it says it's almost parallel to AE, so the angle of incidence is 90 degrees 6 b)(ii) at critical angle the refracted ray is at 90 degrees while here the incident ray is 90 degrees. So that refracted ray in this case is the critical angle which is 43 degrees. 6 b)(iii) refractive index=...

    Physics: help me please :cry:

    welcome :) yup........if the speed increases......the object is accelerating. If the speed is constant the acceleration is zero. Speed is the same as velocity though there is no direction in it but yeah they are same in the sense of mangnitude. Acceleration is the change in velocity over a given...

    Dont mention it :D

    GUYS HELP 4 PHYSICS PAPER 3

    Yes we have to. For all the calculations we have to change the quantities given into its SI unit E.g.- if the mass in the problem is given in grams, change it to kilograms

    Do we lose all marks for forgetting paragraphts in english paper 2?

    If you havent used paragraphs or used them but it appears to be like you havent used them, sorry to say they will cut your marks but only like 2 to 3 marks...not more than that!

    Physics: help me please :cry:

    Scalars are quantities with magnitude only. eg- speed gives you the number/magnitude but you wont know the direction that object is moving in. Vectors are quantities with magnitude and direction. eg- velocity gives you both the direction as well as magnitude of the object moving. Renewable...
