Answer:
a) 2Hz
b) 0.5seconds
c) 0.34m/s
Explanation:
a) Frequency is defined as the number of oscillations completed by a wave in one second.
If my finger is dipped into a pan of water twice each second, it means that my hand has made 2 oscillations through the water in one second. An oscillation is a to and fro movement of a particle, body or wave through a medium.
Based on the conclusion, the frequency of the waterwaves will be 2Hertz or 2cycles/sec.
2) Period T of a wave is defined as the time taken by a wave to complete one oscillation. It is the reciprocal of the frequency of a wave.
T = 1/F
Given frequency = 2Hertz
T = 1/2
T = 0.5seconds
Period of the water wave is 0.5seconds
c) speed of the wave v is expressed according to the relationship:
velocity = frequency × wavelength
Given:
Frequency = 2Hertz
Wavelength = 0.17m (Since it is the difference between two successive crest or trough of a wave)
Velocity = 2×0.17
Velocity = 0.34m/s

Answer:
1. A Spacecraft to Survive Deep Space
2. That includes food, clothing, mid-deck seats, flight tools, cameras, parachutes, safety equipment, sleep restraints and, most importantly, the astronaut spacesuits -- known as "extravehicular mobility units."
3. A new compact toilet, smaller than the one on the space station. ... suppression system or exercise equipment that helps astronauts stay in shape. New Spacecrafts
