Think about all the different types of heat engines you might encounter in any given day. Think about how they operate and what

their limitations might be. Assume that these heat engines operate at the Carnot efficiency. In your initial discussion post, respond to the following: List 10 different types of heat engines. Discuss what limits the efficiency of each. What changes to the device or to the environment would increase the efficiency

liubo4ka [24]

Answer:

Resistance, R=0.529\ \Omega

Explanation:

Given that,

Voltage of the battery, V = 9 volts

Current produced in the circuit, I = 17 A

We need to find the resistance when shorted by a wire of negligible resistance. It is a case of Ohm's law. The voltage is given by :

V=IR

R=\dfrac{V}{I}

R=\dfrac{9\ V}{17\ A}

R=0.529\ \Omega

So, the resistance in the circuit is 0.529 ohms. Hence, this is the required solution.

The behaviors that light exhibits are reflection, refraction, diffraction, polarization, and dispersion. Answer
Molodets [167]
I believe the correct answer is false. The behaviors that light exhibits are reflection, refraction, diffraction but not polarization, and dispersion. Light<span> behaves as a wave - it undergoes reflection, refraction, and diffraction just like any wave would. Hope this answers the question.</span>

Most of an atom is empty space.<br> a. True<br> b. False
Iteru [2.4K]
 <span>Yes, the vast majority of an atom is indeed empty space. Most of it's mass is centered in the nucleus. Flying around the nucleus are the electrons, but they're very very far away (on an atomic level anyway). Most of the atom is the space between the nucleus and the electrons.</span>

How do the linear equation and quadratic equation are differ? What do we suffer on earth? What if we would live on the moon /sun
Aleksandr [31]

A quadratic equation is a parabola and a linear equation is a straight line.

  • Quadratic Equation is an equation in which the power of variable mostly x is two.
  • Standard quadratic equation is  ax^{2} +bx+c=0
  • Any linear equation have form like y=mx+c
  • The moon has no atmosphere, no weather and no oceans of water. Its surface is in a perpetual vacuum.
  • Because the moon's gravity is only one-sixth that of the Earth's gravity, Apollo astronauts had to risk of stumbling or falling.
  • Astronauts on the moon were protected from the extreme temperatures by their spacesuits. The suits had several layers of insulating material covered by a highly reflective outer layer.
