EVEN IF they can build such a machine, it's not too useful.
-- If the wind starts and stops, your car would do the same thing.
-- If the wind isn't blowing at all, your car is going nowhere. (and fast)
-- You could never move along the road faster than the wind is moving along the road.
-- You could never move in the direction towards where the wind is coming from. This has been proven before, with the technological marvel known as the "sailboat".

Answer:
Angle of reflection = 30°
Explanation:
One of the laws of reflection is that the angle of incidence is equal to the angle of reflection.
The angle at which the light strikes the mirror is called the angle of incidence while the angle at which the light gets reflected back is called angle of reflection.
In this case, the angle of incidence is 30 degrees. So, we can say that the angle of reflection is also equal to 30 degrees.
Answer:
Let f be force of friction on the blocks kept on inclined plane. T be tension in the string
For motion of block on the inclined plane in upward direction
T - m₁gsin40 - f = m₁a
f = μ m₁gcos40
For motion of hanging block on in downward direction
m₂g - T = m₂ a
Adding to cancel T
m₂g - - m₁gsin40 - μ m₁gcos40 = a ( m₁+m₂ )
a = g (m₂ - - m₁sin40 - μ m₁cos40) / ( m₁+m₂ )
Putting the values
a = 9.8 ( 4.75 - 2.12-1.045) / 7.6
2.04 m s⁻²
M₂ will go down and M₁ will go up with acceleration .
Explanation:
Answer:
Rebounding involves a change in the direction of an object; the before- and after-collision direction is different. ... As mentioned above, if cars rebound upon collision, the momentum change will be larger and so will the impulse. A greater impulse will typically be associated with a bigger force.

Answer: informative array
Explanation:
"The periodic table of elements arranges all of the known chemical elements in an informative array. Elements are arranged from left to right and top to bottom in order of increasing atomic number. Order generally coincides with increasing atomic mass. The rows are called periods."
