koban [17]

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

lawyer [7]

According to the research, the correct option is mood and emotions. When luana is nervous about a particular project, her <u>mood</u><u> and </u><u>emotions</u> affect(s) her ability to creatively solve problems.

<h3>What is nervous?</h3>

It is usually related to the emotional tension or turmoil that a person experiences.

It can refer to very diverse situations, it denotes insecurity in oneself in the face of certain pressures, which generate a large volume of expectations in those who must go through them, and the result is a kind of emotional overload in mood and emotions that prevents acting in a normal way in front of them.

Therefore, we can conclude that according to the research, the correct option is mood and emotions. When luana is nervous about a particular project, her <u>mood</u><u> and </u><u>emotions</u> affect(s) her ability to creatively solve problems.

A 75-year-old male with long-standing hypertension and angina due to coronary heart disease presents with ankle edema, nocturia,
Debora [2.8K]

Left ventricular hypertrophy increases the chance of sudden death. Studies have shown that the problem increases the risk of developing some diseases, such as heart failure, stroke, coronary heart disease and even sudden death.

<h3>A. How does hypertension cause heart failure?</h3>

In summary, heart failure can occur in the natural history of patients with hypertension, as a result of the action of a wide set of adaptive mechanisms triggered by the persistent increase in ventricular afterload, resulting in diastolic or systolic dysfunction.

<h3>B. What is the significance of left ventricular hypertrophy in terms of a compensatory mechanism and a pathological mechanism in the progression of heart failure?</h3>

The term cardiac hypertrophy refers to increased myocardial mass. It is an adaptive response to a physiological or pathological overload. This adaptation occurs as a response of the heart to an overload of work and can be classified as concentric or eccentric.

<h3>C. Explain the management and treatment for this diagnosis.</h3>

Treatment depends on the underlying cause and may involve medication or surgery. Left ventricular hypertrophy caused by aortic valve stenosis may require surgery to repair the narrowed valve or to replace it with an artificial valve.

With this information, we can conclude that left ventricular hypertrophy increases the chance of sudden death. Studies have shown that the problem increases the risk of developing some diseases, such as heart failure, stroke, coronary heart disease and even sudden death.
