C. Magnetism
It is a physical property, not a chemical property.
Answer:
480.2 m
Explanation:
The following data were obtained from the question:
Speed of sound (v) = 343 m/s.
Time (t) = 2.8 s
Distance (x) of the cliff =?
The distance of the cliff from the woman can be obtained as follow:
v = 2x /t
343 = 2x /2.8
Cross multiply
2x = 343 × 2.8
2x = 960.4
Divide both side by the coefficient of x i.e 2
x = 960.4/2
x = 480.2 m
Therefore, the cliff is 480.2 m away from the woman.
Answer:
Tangential speed = 5.72 m/s
Centripetal acceleration = 
Explanation:
The tangential speed, V, is given by
where 
is the angular speed and is given by 
(f is the angular frequency or frequency of rotation)
Thus,
The centripetal acceleration,a, is given by
The least possible flight visibility prerequisite for VFR flight above 1200 feet AFL and below 10000 feet MSL for the duration of daylight hours is 1 mile in the external controlled airspace. In aeronautics, visual meteorological conditions or as called as VMC is an aviation flight group in which visual flight rules or VFR is allowed that is in circumstance in which pilot have adequate visibility to fly the aircraft sustaining visual leave-taking from terrain and other aircraft. They are the contradictory of instrument meteorological conditions. The border standards among instrument meteorological conditions and visual meteorological circumstances are recognized as the visual meteorological conditions minima and are well-defined by visibility, cloud ceilings for take offs and landing and cloud allowances.
Answer:
.004 Hz
Explanation:
Frequeny is cycles per second. An oscillation is 1 cycle
F=cycles/sec
4/100
=0.004Hz (Hz- Hertz=1 cycle/sec)
