How do media literacy , information literacy and technology literacy and media and information literacy differ in terms of use?
Answer:
Media literacy creates a conscious awareness, the ability to understand, analyze, the messages various media like the newspapers, the radio, that is for the consumer, and it also promotes how best media create information for production.
While information literacy and technology literacy differs from other literacy asked in the question above, as information literacy and technology could be used when describing getting information through adequate research and further dishing out this available information so as to effectively use the information with the aim to solve problems, create awareness, or educate, through technologies such as for example, email.
Lastly, media and information literacy differ in terms of use from the other two explained above, as media and information literacy describes discerning information credibility, accuracy, and objectivity of sources they come from, and it shows people how important it is to have credible information to make informed judgments and the ethical use of the information they consume.
After rubbing the hair on your head with a balloon, you determine there are 2.4 x 1018 electrons on your head. What is the charge, in coulombs (C), of your head?
Answer:
q = 0.384 C
Explanation:
The total charge present at the head can be easily found out by multiplying the charge on a single electron with the total number of electrons present on the head:
[tex]q = ne[/tex]
where,
q = total charge on head = ?
n = total no. of electrons on the head = 2.4 x 10¹⁸
e = charge on 1 electron = 1.6 x 10⁻¹⁹ C
Therefore,
[tex]q = (2.4\ x\ 10^{18})(1.6\ x\ 10^{-19}\ C)[/tex]
q = 0.384 C

The shortening of a transmitted signal's wavelength and/or an increase in its frequency, which indicates that the object is
moving toward the observer, is called the
Answer: The Doppler effect occurs when a source of a wave is moving relative to an observer (or the observer is moving relative to the source). In this case, the apparent frequency of the sound, as heard/seen by the observer, is shifted with respect to the original frequency of the wave.
More specifically, the relationship between the apparent frequency, f', and the original frequency, f, is given by:
where:
is the velocity of the wave
is the velocity of the observer relative to the source, and it is positive if the observer is moving towards the source, and negative if the observer is moving away from the source
is the velocity of the source relative to the observer, and it is positive if the source is moving away from the observer, and negative if the source is moving towards the observer
The doppler effect occurs in many daily-life situations: for instance, when an ambulance approaches you, you hear an increase in the apparent frequency of the siren due to the Doppler effect. Another example is the movements of distant galaxies from us: when they move away from us, the apparent frequency of the light they emit decreases, so their wavelengths appear to increase towards the red color (red-shift); on the contrary, when they are moving towards us, the apparent frequency seems to increase, so the wavelength seems to decrease towards the blue color (blue-shift).
Explanation:
What effect would constriction of the blood vessels have on the body?
Answer:
When blood vessels constrict, the flow of blood is restricted or decreased, thus retaining body heat or increasing vascular resistance. this makes the skin turn paler because the blood reaches the surface, reducing the radiation of heat. hope this helps

Explanation:
A gas mixture has 10% O2, 50% Ar (40 gmw) and 40% Pu (244 gmw). What is the density of this mixture?
Answer: 5.39g/L
Explanation:
We need to calculate the average molar mass of the mixture which will be:
= (10 × 32) + (50 × 40) + (40 × 244) / 100
= (320 + 2000 + 9760) / 100
= 12080 / 100
= 120.8g/mol
Since the volume occupied is 22.4L and 1 mole of the gas will occupies 22.4L given the standard temperature conditions, then the density of the mixture will be:
= Mass / volume
= 120.8 / 22.4
= 5.39g/L
Therefore, the density of the mixture will be 5.39g/L.

Explain Newton's Law Of Gravity, and explain how the formula works correctly and combines mathematical arithmetic to figure out gravity.
Answer:
Explanation:
Newton's Law Of Gravity states two masses will have an attraction force that is proportional to their masses and inversely proportional to the square of their separating distance.
Mathematically it is expressed as Force = G * M1 * M2 / d^2 where
G is the gravitational constant, M1 and M2 are the masses and d is the separating distance.

The angular velocity is the ration of the change in the angle turned to time.
Why does the angular velocity increase?The angular velocity is the ration of the change in the angle turned to time. As such, the angular velocity is measured in radians per second. We have been told that the athlete is supposed to perform the jump between figures 1 and 2 in multiple somersaults.
Each time the athlete somersaults, the angular velocity changes. As such, the rate of change of the angular velocity between figures 1 and 2 would be quite high.
On the other hand, the athlete jumps straight vertically down between figures 2 and 3 and does not turn. Hence, the angular velocity decreases.
