Answer:
no
Explanation:
most psychologists are skeptical of ESP and believe it's not real. There actually more skeptical of ESP than other scientists.
Here is the difference between apparent magnitude and absolute magnitude. When we say apparent magnitude, this is the measurement of the brightness of the star of how it appears on Earth; on the other hand, absolute magnitude is the measurement of the brightness of the star at a <span>standard distance of 32.6 light years, or 10 parsecs. Hope this answers your question.</span>
Answer:
B. 1700 Hz, 5100 Hz
Explanation:
Parameters given:
Length of ear canal = 5.2cm = 0.052 m
Speed of sound in warm air = 350 m/s
The ear canal is analogous to a tube that has one open end and one closed end. The frequency of standing wave modes in such a tube is given as:
f(m) = m * (v/4L)
Where m is an odd integer;
v = velocity
L = length of the tube
Hence, the two lowest frequencies at which a dog will have increased sensitivity are f(1) and f(3).
f(1) = 1 * [350/(4*0.052)]
f(1) = 1682.69 Hz
Approximately, f(1) = 1700 Hz
f(3) = 3 * [350/(4*0.052)]
f(3) = 5048 Hz
Approximately, f(3) = 5100 Hz
Answer:
* to make more income
*to became popular on stock markers
*to be known as a good business
V = wf
ex) 5m • 16 Hz = 80 m/s
5m • 20 Hz = 100 m/s
Answer : True because when multiplying the same wavelength with an increase in frequency, will give you a higher velocity (speed).
