Wavelength = (speed) / (frequency)
The speeds of the two possible signals are equal, just like
all other forms of electromagnetic radiation.
Wavelength of 895 MHz = (3 x 10⁸ m/s) / (8.95 x 10⁸/s) = 0.335 m
Wavelength of 2560 MHz = (3 x 10⁸ m/s) / (2.56 x 10⁹/s) = 0.117 m
While gravitational pull pulls us down the opposing force pusshes us upward and cancels each other out
Answer:
Input force is the initial force used to get a machine to begin working. Machines are designed to increase the input force for a larger output force. The quality of a machine is measured by mechanical advantage. The mechanical advantage is the ratio of the output force to the input force.

Answer:
The weight of the air above is smaller
Explanation:
As altitude increases, the amount of gas molecules in the air decreases. The air becomes less dense than air nearer to sea level. This is what people mean by “thin air”. Thin air exerts less pressure than air at a lower altitude.
Explanation:
Velocity (v) is a vector quantity that measures displacement (or change in position, Δs) over the change in time (Δt), represented by the equation v = Δs/Δt. Speed (or rate, r) is a scalar quantity that measures the distance traveled (d) over the change in time (Δt), represented by the equation r = d/Δt.
