Specific Questions

5.The speed shown on a car’s speedometer is proportional to the rate of rotation of the tyres.
The variation of the diameter of a tyre as it wears introduces an error in the speed shown on the
speedometer.
A car has new tyres of diameter 600 mm. The speedometer is accurately calibrated for this
diameter.

3. A particle has velocity V at an angle θ to the horizontal.
The components of the particle’s velocity are Vv upwards in the vertical direction and Vh to the
right in the horizontal direction, as shown

7. A stone is thrown horizontally from the top of a cliff and falls into the sea some time later. Air
resistance is negligible.
Which graph shows how the vertical component vv of velocity of this stone varies with its
horizontal component vh of velocity as it moves through the air

10. A stone is dropped from a tall building. Air resistance is significant. The variation of distance
fallen with time is shown by the dashed line.
A second stone with the same dimensions but a smaller mass is dropped from the same building.
Which line represents the motion of the second stone?


12. A cylindrical iceberg of height H floats in sea water. The top of the iceberg is at height h above
the surface of the water

16.An empty glass beaker has a mass of 103 g. When filled with water, it has a total mass of 361g.
When filled with cooking oil, it has a total mass of 351 g.
The density of water is 1.00 gcm–3.
What is the density of the cooking oil?

Thankyou so much Sir! Don't know where I'd be without your channel at this point 💗Finally understanding these questions

Sir you put alot of effort into these videos thanks Alot! still am amazed how did the examiner give a university level question in this paper mcq 12 was 🤯

[herox]

sir, at 40:02 i have also heard that particles at equilibrium do not move, if im wrong can u plz explain when does that concept apply?

[cappybaraeats]

for q23, why not B, i thought at B highest kinetic energy
by the way thank you for the video until now u are the best at explaining physics

[herox]

sir, why does steel and brass both have the same force of 40? shouldnt it be 20 each? 34:21

5:52 why did you put 12 in place of uncertainty to calculate percentage uncertainty?
