Answer:
- Which of the following does not move as a transverse wave?
<em>B. sound waves</em>
because sound waves are longitudinal waves having compressions and rare factions.
Which of these effects describes the change in pitch we hear
moving motorbike goes past?
<em>D</em><em>.</em><em> </em><em>Doppler</em><em> </em><em>eff</em><em>ect</em>
Doppler effect is the phenomenon where there is apparent change in frequency (pitch) and wavelength of a wave due to relative motion of the sound source.
Which of the following does not make use of total internal reflection.
<em>B</em><em>.</em><em> </em><em>Endos</em><em>cop</em><em>e</em>
Endoscope doesn't use total internal reflection since no refraction takes place.

Remember that w=mg where w is weight in Newtons, m is mass in kilograms, and g is gravity in
m/s2
. For example, for Earth, 445 N = 45.4 × 9.8
m/s2
:Notice that the x-axis values will be gravity in
m/s2
, which is already given in the table, and the y-axis values will be the weight in Newtons. Remember to round your weights to a whole number, and to enter the points starting with the lowest gravity (moon, then Mars, then Venus, then Earth).
