According to the Jefferson lab, "The scientific definition of work is: using a force to move an object a distance (when both the force and the motion of the object are in the same direction.)"
Answer: electromagnetic radiation
Explanation: range of wavelengths is called visible light or simply light. A typical human eye will respond to wavelengths.
D =vt
since it has to go down and come back up, you must half the time in this problem.
d = (1498)(0.5•2.5)
d = 1872.5 m
Answer:
Tides occur 2 times a day.
Explanation:
Because that's what left over after removing the moon's average gravitational pull at each different location on earth.
Answer:
15.065ft
Explanation:
To solve this problem it is necessary to consider the aerodynamic concepts related to the Drag Force.
By definition the drag force is expressed as:
Where
is the density of the flow
V = Velocity
= Drag coefficient
A = Area
For a Car is defined the drag coefficient as 0.3, while the density of air in normal conditions is 1.21kg/m^3
For second Newton's Law the Force is also defined as,
Equating both equations we have:
Integrating
Here,
Replacing:
