The flywheel of a steam engine begins to rotate from rest with a constant angular acceleration of 1.33 rad/s2. It accelerates fo
Svetradugi [14.3K]

Answer:

We first to know that if the wheel rotates from rest means that at t=0 the velocity and the angle rotated is 0.

Then, we know:

\alpha = 1.33 = \frac{dw}{dt}

Integrating 2 times, we have:

w = 1.33t\\angle =0.665t^{2}

For the first 27.9 s, we have:

w = 37.107 rad/s

angle = 517.6426 rad

For the next seconds, according to the text, the angular velocity is constant so

w = 37.107 rad/s and hence, integrating:

angle =37.107t

Then, the time remaining is:

53.5 - 27.9 = 25.6  

So for the next 25.6 seconds we have:

angle = 37.107*25.6=949.9392 rad

Finally, we add the 2 angles and we have as a result:

angle = 517.6426+949.9392=1467.5818

Alex777 [14]

Answer:

Chemical energy is converted to thermal energy and electrical energy.

Explanation:

The sugar present in the apple is broken down into Glucose. This is chemical energy stored in the apple which is broken down into energy which is utilized by body for everyday works. The chemical energy gets converted to thermal energy which warms the body and electrical energy due to which the heart beats.

Schach [20]

Answer:

d. The earth rotates around the sun

Explanation:

  • Nicolas Copernicus is considered the first person to give the theory of heliocentric, or Sun-centered system of our planetary system.
  • In the heliocentric system, it is considered that the sun is stationary and the earth revolves around the sun.
  • He stated that the sun is at the center of the universe and the earth spins on its axis once daily and revolves around the sun in one year.
  • And today we know it is correct that earth rotates on its own axis and also revolves around the sun.

It decomposes in a first-order reaction with a rate constant of 14 s–1. how long would it take for an initial concentration of 0
VikaD [51]
The rate constant of a reaction can be computed by the ratio of the changes in the concentration and time take taken for it to decompose. Thus, if the rate constant is given to be 14 M/s, we have 

rate = \frac{-(C_{new} - C_{old})}{t}

where C are the concentration values and t is the time taken for it to decompose.

14 = \frac{-(0.02 - 0.06)}{t}
t = 0.003 s

Thus, it will take 0.003 s for it to decompose.
Answer: 0.003 s
