I think you're supposed to use a formula that helps you find the weight in the first exercise and the mass in the second exercise on the Earth and the Moon. Keep in mind that in physics mass and weight mean different things.
#1
As we are increasing the frequency in the simulation the wavelength is decreasing
So if speed remains constant then wavelength and frequency depends inversely on each other
If we are in boat and and moving over very small wavelengths then these small wavelength will be encountered continuously by the boat in short interval of times
#2
As we are changing the amplitude in the simulation there is no change in the speed frequency and wavelength.
So amplitude is independent of all these parameter
Amplitude of wave will decide the energy of wave
So light of greater intensity is the light of larger amplitude
#3
In our daily life we deal with two waves
1 sound waves
2 light waves
Answer:
The force on the bug and the force on the bus are the same.
Explanation:
Newton's Third Law of Motion states that, "For every action, there is an equal and opposite reaction" or it can be restated that If a high-speed bus exerts a force on an innocent bug, then the innocent bug must exert a force of equal magnitude and opposite direction back on the high-speed bus.
Note: though the forces are equal but the effect are not, in this case the innocent bug was splattered but the bus was not destroyed.
Answer:
I believe c and d is the answer because a and b are more material properties.
I think its A. hope this helps
