True
10N/Kg
What is the gravitational Field strength on Earth?
What is the wave equation?
Give the names of the symbols and their units
v = f λ
v = Wave speed (m/s)
f = Frequency (Hz)
λ = Wavelength (m)
The symbol equation of Hooke's Law?
And give the names of the symbols and their units!
What is F = k x
F = Force (N)
k = Spring constant (N/m)
x = extension (m)
20-20,000Hz
What is the range of Human Hearing?
All EM waves are this type of wave...
AND
EM waves cannot pass through a vacuum, true or false?
What are Transverse waves
AND
False
What is the symbol equation for Weight on a planet?
Give the names and units of the symbols
W = m g
W = Weight (N)
m = Mass (Kg)
g = Gravitational Field Strength (N/Kg)
What is the wavelength of a 50,000Hz light wave?
v=300000000m/s
what is 167micrometers?
A spring has a spring constant of 14N/m and has a force of 3N exerted on it. What is the extension of the spring?
What is 0.21m?
Sound waves which have a frequency greater than 20,000Hz
This type of EM wave is used in remote controllers, night vision equipment and heating.
What is Infrared Radiation?
Mr Folds is a great bloke and has a mass of 80Kg, what is his weight on Earth?
g=10N/Kg
What is 800N?
A frog jumps into a pond and produces waves which have a speed of 4m/s and a time period of 2ms. What is the wavelength of the waves?
what is 8mm?
A spring has an original length of 10cm. When a 200g mass is dangled on it, it extends to have a new length of 45cm. What is the spring constant of the spring?
What is 5.7N/m?
The Amplitude has decreased.
Detecting counterfeit bank notes, Fluorescent lamps and dentistry are common uses of this type of EM wave
What is ultraviolet light.
In his spare time, Mr Folds enjoys travelling to the moon in his Peugeot Spaceship. On Earth he has a mass of 80Kg. What will happen to his mass when he goes to the moon?
Mass will stay the same, it is his weight which would change.
Mr Folds has a Xray gun, and a radio wave gun and is ready to fire it at a target 100m away. The X-rays have a wavelength of 1nm, the radio waves have wavelength of 10m. Which one will hit the target first?
They both hit at the same time because they both move at the speed of light.
This thing is a measure of how "stiff" and difficult to stretch a spring is
What is the spring constant?
Mr Folds sings a C and then sings the next F at the same loudness. What has changed about the wave Mr Folds sings?
The frequency has increased
or wavelength has decreased
or the time period has decreased.
Which types of EM wave can lead to cancer?
What are UV, X-ray and Gamma rays?
Mr Folds' frequently enjoys taking his Peugeot Spaceship around the solar system. On Earth the Peugeot has a weight of 9500N. When he takes the peugeot to Jupiter it has a weight of 24000N. What is the gravitational field strength on Jupiter?
g(Earth) = 10N/Kg
What is 25.3N/Kg?
Mr Folds shouts "Physics is great!" at a wall and hears a response 3s later. How far away is the wall?
v in air = 334m/s
What is 501m?
