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

Hello☺Please can you explain dipole induced dipole forces and induced dipole induced dipole forces PLEASE. Is induced dipole the same as momentary dipole?
  • 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

what exactly guides you when describing the deffraction pattern?
  • All diffraction patterns have the same description. If you use red light light, then red and dark. Blue light, then blue and dark. But with red, the bands are wider since red has a larger wavelength.

Does vapour pressure affect dynamic equilibrium.Explain fully
  • yes,according to the Le chatelier's principles,the equilibrium will move(change the position)in order to withstand/reduce the pressure in the system.example,in this case of having more molecules on the right hand side than on the left side,increasing pressure will cause the equestion to move to the left side to balance the pressure molecule and vice-versa

What is the influence of isolating mechanisms?
  • Isolating mechanism is a form of sympatric speciation. (Formation of a new species due to a mechanism of reproductive isolation). This does not allow for the reproduction bet diff species to take place due to: Temporal isolation, courtship behaviour, Adaptations to different Pollinating Agents, prevention of fertilisation because of diff copulatory organs and hybrid infertility.

What are a few examples of Action-reaction pairs and what are the properties of action-reaction pairs? Thanks
  • The forces are of the same magnitude, act in opposite directions on different objects.
    Since they act on different objects, they obviously cannot cancel out.

    Every force has a reaction force, which is sometimes not very obvious.

    Easy examples:
    rocket taking off -
    rocket applies force on gas, and gas applies force on rocket.
    (rocket and gas takes off in opposite directions!)

    firing a gun -
    gun applies force on bullet, and bullet applies force on gun (hence gun recoils)
    (bullet and gun takes off in opposite directions)
    (this can get a little complex if you start thinking about the compression gases, but this is an ok explanation)

Explain briefly hw doppler effect functions nd what it may be used for?
  • example:
    If a car approaches with a siren on, each new pulse from the siren has a shorter and shorter distance to travel to reach you (the car is getting closer to you). This creates a higher frequency of pulses for the listener. Hence a higher frequency is heard.

    Uses include:
    1) to measure the rate of blood flow
    2) or the heartbeat of a foetus in the womb
    3) speed traps (radar type)
    4) used to measure the speed at which stars and galaxies are approaching or receding from us
