Answer:
Angular speed of the bacteria motor is 1447rad/s
t = 4.342 × 10^-3 seconds
Explanation:
Hint: Do you remember circular motion in physics???
Okay, let's go
Given:
radius of 1.61 10-8 m
tangential speed at the rim of 2.33 10-5 m/s
Let's recall that angular velocity
ω = Vt/r
Where,
Vt = 2.33 10-5 m/s
r = 1.61 10-8 m
ω = ?
ω = 2.33 ×10-5 m/s = 1447rad/s
1.61 ×10-8 m
Angular speed of the bacteria motor is 1447rad/s
Let's find the elapsed time too
Since The angular velocity is said to be constant, there will be no acceleration (a = 0)
Using:
θ = ωot + (1/2at^2)
t = θ/ωo
(θ = 1 revolution or 2π rad, ωo = 1447rad/s)
t = (2π rad)/(1447 rad/s)
t = 4.342 × 10^-3 seconds
Answer: C. Certain bacteria live within rocks kilometers below the Earth’s surface.
Explanation:
Bacteria are microscopic, usually single-celled living organisms that can be found in many environments. The live in practically anywhere on the planet because they are able to adapt to environmental changes. Bacteria regulate changes or modifications to their cell envelope in a coordinated way, allowing them to survive in different environments.
The main difference between bacteria and other cells is that bacteria are cells that do not contain a nucleus or other membrane-bound organelles.
These organisms can live in soil, the ocean and also inside the human gut. They can be dangerous, for example, when they cause infections they are able to injure different cells and tissues and compromise the immune system. On the other hand, most of the time they are beneficial, as in the process of fermentation such as in wine or yougurt, or helping with the digestion.
<h2>Answer is option "A"</h2>
Explanation:
- The concept of actor-observer bias states that the causes of behaviors and events in our lives are motivated by attribution. Attribution is an inference that we make about our behaviors and the behaviors of others. The attributions we make depend directly on whether we are the actor or the observer.
- The actor-observer difference inclination will be progressively articulated in circumstances where the results are negative. For instance, in a circumstance where an individual encounters something negative, the individual will regularly accuse the circumstance or conditions. When something antagonistic happens to someone else, individuals will frequently censure the person for their own decisions, practices, and activities.
- Hence, the right answer is option A "actor-observer perspective".
C. Deforestation is where the land is converted into a NON-FOREST use.
A. Desertification is when farming, overgrazing, climate change, and/or seasonal drought change farmland into land that cannot support plant life.
Soooooo, the answer should be A. Desertification.
and yes, C would be wrong
