1 Newton of force is required to produce that.....
If he feels like, is interested in it, and is able to grasp it, then why not ? Why not indeed ?
Answer:
the statement is TRUE
Explanation:
When we move in the same direction, the relative speed of the two vehicles is lower, so we must subtract their speeds, if the result is positive the vehicles approach and if it is negative they move away.
v_relative = v₁ - v₂
When the two vehicles go in opposite directions, the speed is much higher, so we must add their speeds
v_relative = v₁ - (-v₂))
v_relative = v₁ + v₂
therefore the statement is TRUE
Infared = used by police
gamma = short wavelength
radio = largest wavelength
visible = only ones we can see
