Suppose the fetus's ventricular wall moves back and forth in a pattern approximating simple harmonic motion with an amplitude of 1.7 mm and a frequency of 3.0 Hz. Find the maximum speed of the heart wall (in m/s) during this motion. Be careful of units!

Answers

Answer 1

Answer:

Answer:

The maximum speed of the heart wall during this motion is 0.032 m/s.

Explanation:

Given that,

Amplitude of the simple harmonic motion, A = 1.7 mm = 0.0017 m

Frequency of the fetus's ventricular wall, f = 3 Hz

We need to find the maximum speed of the heart wall during this motion. The maximum speed of the object that is executing SHM is given by :

$v_(max)=A\omega$

$v_(max)=2\pi f A$

$v_(max)=2\pi * 3* 0.0017$

$v_(max)=0.032\ m/s$

So, the maximum speed of the heart wall during this motion is 0.032 m/s. Hence, this is the required solution.

Which of the following makes gravity increase?A.The mass of forming objects increases.

B.The mass of forming objects decreases.

C.The spherical shape of planets provides the momentum needed to increase gravity.

D.The mass of forming objects is constantly the same.

Answers

The answer is A. The mass of forming objects increases.

Gravity between objects depend on two things: distance and mass. The farther objects are apart, the lower the gravity. However, the mass of an object is directly proportional to gravity. As mass increases in an object, the gravity increases as well.

Base on the given choices above, the correct answer that corresponds to the question where it can explain as to what makes gravity increase is because of the spherical shapes of the planets. It is because it has the ability to provide momentum. In which momentum has the capability of providing mass in motion, allowing the gravity to increase.

a rocket lift off the surface of earth with a constant acceleration of 20 m/sec^2 .how fast will the rocket be going 1 min latter?

Answers

a = v1-v0/t so v1= a*t (v0 is o m/s) v1=
20m/s * 60 s = 1200 m/s

"Acceleration of 20 m/s² " means that the rocket is speeding up,
and its speed becomes 20 m/s greater every second.

Since it started out with zero speed, its speed after 1 minute
(60 seconds) is

(20 m/s /s) · (60 s) = 1,200 m/s .

Differentiate elastic potential energy and chemical potential energy

Answers

Answer: Elastic energy is the energy store in a.. compacted spring; an extended elastic band; and a drawn bow.

Chemical potential energy is position of electrons in specific substance bonds that can be broken (energizes).

This stored energy is released and performs work when the elastic material reverts back to its original position. ... In comparison, chemical potential energy, is the energy released during the formation of chemical compounds.
