Good afternoon mister Gokul. Why is a C-H bond considered as a non-polar bond despite being....polar.How does the symmetrical shape affect it?Thank you
  • No.
    A C-H bond is always a polar bond.
    In some molecules, such as CH4, as a result of the symmetrical shape of the entire molecule, there is an even charge distribution across the ,molecule. So the MOLECULE is regarded as non-polar even though the bonds inside it are polar.

    Another example of this is C=O, which is a polar covalent bond. But in CO2, which is O=C=O the symmatrical shape of the MOLECULE allows for even charge distribution, so the CO2 molecule is a non-polar MOLECULE even though the bonds inside are still polar.

Prove that 2x^2(2x squared) +x+8 >0 for all real values of x
  • Rtp: 2x² + x + 8 > 0 ∀x∈ R
    Proof: ax² +bx + c ⇒ a(x + p)² + q
    if q>0, then it is proven as q is the min/max value
    of the parabola.

    2x² + x + 8
    = 2(x² + 1/2.x) + 8
    = 2(x²+ 1/2.x + 1/16) + 8 - 1/8 → [2×1/16 = 1/8 And it is
    Important that the same value is added and subtracted
    To keep the original value of the equation the same.]
    = 2(x + 1/4 )² + 63/8
    q = 63/8
    63/8 > 0
    : . 2x² + x + 8 >0 ∀ x ∈ R

definition of viscosity
  • viscosity is a measure of the resistance of a substance to flow.

    extra info:the greater the viscosity of a substance,the more slowly it flows. we measure viscosity by determining how long it takes for a liquid to flow out of a narrow tube under the force of gravity. viscosity depends on the strength of inter-molecular forces. the stronger the forces, the greater the viscosity.

a donkey pulls a cart,C, with a mass of 240Kg, attached to to a log of wood, W, with a mass of 80Kg, on a horizontal road, W is tied to the back of C by means of an inelastic rope, which is inclined at 30° to the horizontal. The donkey applies a force of 170N on cart C and the system accelerates at 0,30m.s-2 to the left. TheI force of friction on cart C is 40N. The rope has negligible mass.
Calculate:
a) the magnitude of the force which the rope exerts on C.
b) the force of friction on W.

Good Day,I would like to know the explanation of question 3.4 in the Physical Science Paper 1.for feb-march 2017. It concerns vertical projectile motion.Thank you
  • Hello
    The question is about the height of the BALLOON.
    You have to work out for how long the BALL was moving.
    1) While falling t = 2s (calculate earlier)
    2) Contact with ground t = 0,3s (given)
    3) Rising t = 1,53s
    Total time for BALL = 3,83s
    Therefore BALLOON was moving down for 3,83s
    Find distance moved.
    Find height.

A car of mass 1500 kg is stationary at a traffic light. It is hit from behind by a minibus of mass 2000 kg travelling at a speed of 20 m.s-1. Immediately after the collision the car moves forward at 12 m.s-1. Calculate the speed of the minibus immediately after the collision.
  • You use conservation of linear momentum:
    total linear momentum (before) = total linear momentum (after)
    (mv)1 + (mv)2 = (mv)3 + (mv)4
    (2000)(20) + 0 = (2000)(v3) + (1500)(12)
    V3= 11 m.s forward

  • Yes an induced dipole is a dipole due to their being another atom in close proximity that is either dipole or induced dipole itself. E.g 2 Helium atoms next to each other is an Induced-Induced dipole force.

whats the difference between the control and the experiment?
  • In an experiment, the control group is the unchanged group and has normal conditions
    whereas the experimental group has one variable changed so we can see the result.
    The experimental group is compared to the normal/ control group

    formal definition: A control group in a scientific experiment is a group separated from the rest of the experiment where the independent variable being tested cannot influence the results
