Sonja [21]

Answer: (c) Context Effect

Explanation: Context Effect is an aspect of cognitive psychology which describes how environmental factors afects a person's perception of stimuli. It is known to occur at all scales at which words may be viewed. It is supported by constructive perception, the effect of a context perception is known to be part of a top-down design, the view of the moon through a narrow tube which has affected the perception of the viewer who now see the moon as shrinking in size is a context perception.

A light-year is the distance that light travels in one year. The speed of light is 3.00 × 108 m/s. How many miles are there in o
Alinara [238K]

Answer:

(a) 5.88\times 10^{12}mi

Explanation:

We have given speed of light c=3\times 10^8m/sec

Given time = 1 year =365 days

We know that in 1 minute = 60 sec

1 hour = 60×60 = 3600 sec

In one day = 24 hour = 24×60×60=86400 sec

So in 365 days = 365×86400=3.1536\times 10^7sec

We know that distance = speed ×time=3.1536\times 10^7\times 3\times 10^8=9.46\times 10^{15}m

We have given that 1 mi = 1609 m

So 9.46\times 10^{15}m=\frac{9.46\times 10^{15}}{1609}=5.88\times 10^{12}miSo option (a) is correct

Bats can detect small objects such as insects that are of a size on the order of a wavelength. if bats emit a chirp at a frequen
crimeas [40]
The smallest size of the insect that the bats can detect corresponds to the wavelength of the chirp they emit.

Their chirp has a frequency of
f=69.3 kHz=69.3 \cdot 10^3 Hz
and the speed of the chirp is equal to the speed of sound in air:
v=330 m/s
Therefore the wavelength of the chirp is
\lambda= \frac{v}{f}= \frac{330 m/s}{69.3 \cdot 10^3 Hz}=4.76 \cdot 10^{-3} m
which corresponds to a size of 4.76 mm.
