Answer:
Distance = 30 m
Explanation:
Since the position of the bus is at zero, and distance is a scalar quantity. That is, we are only concerned about the magnitude
If Angela ran to the bus and back to where she started, the distance travelled will be:
Distance = 15 + 15 = 30 m
But her displacement will be:
Displacement = 15 - 15 = 0.
Answer:
1672.98 kJ (increase in internal energy)
Explanation:
Let's first find the energy received by the water in order for it to vaporize.
This is: Energy = mass of water * latent heat of vaporization
Energy = 0.8 * 2.26 * 10^6 = 1808 kJ
We also need to subtract from this the energy needed for the volume increase. This is calculated the following way:
Energy needed for volume change = P (Final Volume - Initial Volume)
Initial volume = 0.8/1000 = 0.0008 m^3
Final volume = 0.8 / 0.6 = 1.333 m^3
Pressure = 1 atm = 101325 Pa
Energy needed for volume change = 101325 (1.333 - 0.0008)
Energy needed for volume change = 135.02 kJ
Total Internal Energy Change = 1808 - 135.02 = 1672.98 kJ
Answer:4.34 miles
Explanation:
first Elevation =
After 1 minute Elevation changes to
Ditsance travelled in 1 minute ==10 mile
Now
tan59=
H=xtan59
tan19=
H=
Equating H
we get
1.319x=10tan19
x=2.61 miles
H==4.34 miles
Explanation:
General relativity is a theory of space and time. ... The central idea of general relativity is that space and time are two aspects of spacetime. Spacetime is curved when there is matter, energy, and momentum resulting in what we perceive as gravity. The links between these forces are shown in the Einstein field equations.
