Answer:
False. Astrology is not a science.
Explanation:
Astrology is a collective term for ideas about the supposed connection between the fate of people and events on Earth and the position of the celestial bodies. It mainly concerns the places in the sky of the sun, moon and planets, which were referred to as stars in ancient times, usually against the background of the fixed stars in the Zodiac. Although astrology cannot be confirmed despite research, and scientists have long rejected the principles of astrology as pseudoscience, many people continue to practice and / or believe in it.
Answer:
A. 50 Hz
B. 2 m/s
Explanation:
We'll begin by converting 20 ms to s. This can be obtained as follow:
1000 ms = 1 s
Therefore,
20 ms = 20 ms × 1 s / 1000 ms
20 ms = 0.02 s
Next, we shall convert the value of the wavelength (i.e 4cm) to m. This can be obtained as follow:
100 cm = 1 m
Therefore,
4 cm = 4 cm × 1 m / 100 cm
4 cm = 0.04 m
A. Determination of the frequency.
Period (T) = 0.02 s
Frequency (f) =?
f = 1 / T
f = 1 / 0.02
f = 50 Hz
Therefore, the frequency of the wave is 50 Hz
B. Determination of the velocity.
Wavelength (λ) = 0.04 m
Frequency (f) = 50 Hz
Velocity (v) =?
v = λf
V = 0.04 × 50
v = 2 m/s
Therefore, the velocity of the wave is 2 m/s
The net force is 12 N to the left.
