Explain the difference between conduction, convection, and radiation.
Answer: Conduction: heat transfer through solids; Convection: heat transfer in fluids; Radiation: heat transfer via electromagnetic waves
A car of mass 500 kg accelerates from rest to 20 m/s in 10 s. Calculate the work done.
W=1/2mv2=0.5×500×202=100,000J
What happens to the wavelength if frequency increases but speed stays the same?
wavelength decreases
Define specific heat capacity
Energy needed to raise 1 kg of a substance by 1°C
A sound wave has a speed of 340 m/s and a frequency of 680 Hz. Find its wavelength.
λ=v/f=340/680=0.5 m
Name the process where gas turns directly to solid.
Deposition
What type of image is formed when an object is placed between a convex lens and its focal point?
Virtual, upright, magnified
In The Avengers, what is Thor’s hammer called?
Mjolnir
A 60 W bulb is connected to a 120 V supply. Find the current drawn.
I=P/V=60/120=0.5A
Which seismic wave is a longitudinal wave?
P-wave
State one difference between transverse and longitudinal waves.
Transverse: particles vibrate perpendicular to wave direction. Longitudinal: particles vibrate parallel to wave direction.
A force of 100 N acts on an object for 5 seconds. If the object starts from rest and its mass is 20 kg, find its final velocity.
a=F/m=100/20=5m/s²
v=u+at=0+5×5=25 m/s
A student uses a convex lens and gets no image on the screen. Give one reason why.
The object is inside the focal length, so the convex lens forms a virtual image, which cannot be projected onto a screen.
I speak without a mouth and hear without ears. I have no body, but I come alive with wind. What am I?
ECHO
An echo “speaks” when a sound is made, but it has no mouth.
It “hears” the original sound to reflect it, but it has no ears.
It has no physical body.
The “comes alive with wind” part is a poetic hint: sound can travel through air (or wind).
What type of lens is used to correct short-sightedness (myopia)?
Concave lens
