Answer:
The compression ratio is 10
Explanation:
Given
--- swept volume
--- compression volume
Required
Determine the compression ratio (CR)
This is calculated as:
The doppler effect has red and blue shifts. A red shift means something is moving farther away, and a blue shift means it is moving closer. The universe has a red shift, and since a red shift means that it is moving farther away, this tells astronomers that the universe is still expanding.
Weight = (mass) x (gravity)
Acceleration of gravity on Earth = 9.8 m/s²
Weight on Earth = (mass) x (9.8 m/s²)
Divide each side by (9.8 m/s²): Mass = (weight) / (9.8 m/s²)
Mass = (650 N) / (9.8 m/s²)
Mass = 66.33 kg (rounded)
Answer:
C
Explanation:
Mantle convection is the very slow creeping motion of Earth's solid silicate mantle caused by convection currents carrying heat from the interior to the planet's surface. The Earth's surface lithosphere rides atop the asthenosphere and the two form the components of the upper mantle.
Answer: There is no change in temperature when heat is given out or taken in by the object
Explanation:
The heat capacity of an object is infinite when it undergoing phase transition since the heat is ued in changing the state of the substance and ntot in raising the teperature of the substiance. Thus, heat capacity is infinite during change of state. This is known as latent heat. The correct option is
There is no change in temperature when heat is given out or taken in by the object
