Answer:
Correct option : (c) period.
Explanation:
The time that is required for a vibrating object to complete one full cycle is called the time period. If f is the frequency of a wave, then the relation between the frequency and the time period is given by :
These are the characteristics of a wave. Some other characteristics are wavelength, amplitude, intensity etc. So, the correct option is (c) "period".
Answer:
1:a
2:c
3:f
4:d
5:f or e
6:d

Hope it helps! also if im wrong sorry. but i already learned this so yeah have a nice day!
Answer:
a ball hanging from a tall pole
Explanation:
work is force times a distance in the direction of the force. The ball just hanging there has no motion, so is associated with no work. Work was probably done in the hanging process, but none after.
Use kinematic equations to solve:
1) yf = yo + vo*t + 1/2at²
yf = final height
yo = initial height
vo = initial velocity
a = acceleration
t = time
yf - yo = vo*t + 1/2at²
yf - yo = h
vo = 0
Thus,
h = 1/2at²
h = 1/2(9.8)(12)² = 705.6 m
2) vf = vo + at
vo = 0
Thus,
vf = at
vf = (9.8)(12) = 117.6 m/s
The weight of a 76 kg astronaut on Earth is 750N.
The weight of a 76 kg astronaut on the Moon is 130N.
The weight of a 76 kg astronaut on Mars is 280N.
The mass is the same everywhere, the weight chages with change of location (gravity field). I rounded all answers to two significant figures. Hope this helps.<span>
