A steam engine only converts 20 percent of its input energy into useful work?

Answer:

A heat engine is a type of engine, (like the motor in a car) that produces ... Heat engines do just the opposite; they take the energy from being warm ... using a flame to heat water into steam, then using the steam to turn a turbine. ... is the percentage of energy input that the engine can convert to useful work.

The pressure in an automobile tire is 2.0 atm at 27°C. At the end of a journey on a hot summer day the pressure has risen to 2.2

Kruka [31]

Hey there!

For this we can use the combined gas law:

$\frac{P_{1}V_{1} }{T_{1}} = \frac{P_{2}V_{2} }{T_{2}}$

We are only working with pressure and temperature so we can remove volume.

$\frac{P_{1} }{T_{1}} = \frac{P_{2} }{T_{2}}$

P₁ = 2 atm

T₁ = 27 C

P₂ = 2.2 atm

Plug these values in:

$\frac{2atm}{27C} = \frac{2.2atm}{T_{2}}$

Solve for T₂.

$2atm = \frac{2.2atm}{T_{2}}*27C$

$2atm * T_{2}={2.2atm}*27C$

$T_{2}={2.2atm}\div2atm*27C$

$T_{2}=1.1*27C$

$T_{2}=29.7C$

Convert this to kelvin and get 302.85 K, which is closest to B. 330 K.

Hope this helps!

Why doesn't the steepness of a frictionless ramp affect the velocity of the block at the bottom of the ramp? (Hint: Discuss cons

AleksandrR [38]

Answer:

<h2>Because energy is conserved, the kinetic energy of a block at the bottom of a frictionless ramp is equal to the gravitational potential energy of the block at the top of the ramp. ... Therefore, the block's final velocity depends on the height of the ramp but not the steepness.</h2>
