Answer: Context Effect
Explanation:
<u>Context effect</u> refers to <u>the influence that external factors (the environment, for example) have on the perception of a stimulus</u>. This is a well-known aspect of cognitive psychology.
In fact, the situation stated in this question is a good example: It is not the same to observe the Moon with a naked eye and taking into account factors such as cloudiness, dust and whatever is surrounding this view that have effects on the observation; than observing this same Moon with a narrow tube in which our eyes focus only on the lunar surface, without taking into account the rest that surrounds that horizon.
The medium is glass (index of refraction: 1.70)
Explanation:
We can solve the problem by using the concept of index of refraction.
The index of refraction of a medium is given by:
where
is the speed of light in a vacuum
v is the speed of light in the medium
For the medium in this problem, we have
So, the index of refraction of this medium is
And looking at tables of index of refraction of various materials, we see that various types of glass have index of refraction of 1.70.

Answer:
Explanation:
Given
mass of hot metal
specific heat
mass of water
Temperature pf water
Final Temperature
let be the temperature of hot metal ball
Heat lost by heat metal bolt is gained by water in calorimeter
Heat lost by hot metal bolt
Heat gained by water
Heat used by electric heater :
Q = m • c • ∆T
Q = (75 kg)(4200 J/kg°C)(43°C - 15°C)
Q = 8.82 × 10⁶ J
Cost of electrical energy :
Cost = (8.82 × 10⁶ J)/(3.6 × 10⁶ J) • ($ 0.15)
Cost = $ 0.3675
AM and FM are the two types of modulation that an omnidirectional antenna transmit.
<h3>What is an
omnidirectional antenna?</h3>
An omnidirectional antenna is also referred to as an isotropic antenna and it can be defined as a type of antenna that is designed and developed to radiate equal radio power or intercept radio-frequency (RF), especially in all directions perpendicular to an axis.
In Science, there are two types of modulation that an omnidirectional antenna transmit and this include the following:
- Frequency modulation (FM).
- Amplitude modulation (AM).
