Answer:
E) the flow of energy due to a temperature difference.
Explanation:
Heat can be described as the flow of energy due to a temperature difference.
Which is expressed mathematically as;
H = MCΔT
Where;
H is the quantity of heat in a body, measured in Joules
M is the mass of the body, measured in kg
C is the specific heat capacity of the body, J/kg.K
ΔT is change in temperature or temperature difference.
So, heat energy in any system flows from a hotter region to a colder region due to temperature difference.
E) the flow of energy due to a temperature difference.
<span>A plane flies along a straight line path after taking off, and it ends up 210 km farther east and 90.0 km farther north, relative to where it started. we should use Pythagoras theorem for this.
distance^2= 210^2 + 90^2.=228.47km, when rounding off this would comes around 230 km</span>
Answer:
The answer you would be looking for is A.
Explanation:
A couple of things, if the shuttle burned all of it's fuel before entering Earth's atmosphere then that means that the shuttle was accelerating towards Earth until it ran out of fuel. At that point, there is little to no air resistance (friction) by the lack of an atmosphere so it keeps accelerating due to Earth's gravitational force. The closer the shuttle gets to Earth the stronger the gravitational pull the shuttle experiences. Note that, once the shuttle reaches Earth's atmosphere it will cause significant amount of friction and thus will cause the shuttle to slow down.
