Answer: Increase Winding Count
Reduce Resistance
Increase Voltage
Switch From AC to DC
Explanation: HOPE THIS HELPS!!! ^w^
Acceleration is defined as the rate of change of velocity, which, simply put, is a mouthful to describe how fast something speeds up, slows down, or turns. The equation for acceleration is
a = Δv / Δt,
or your final velocity - your starting velocity, then divided by the amount of time. It can also be expressed as
a = (Vf - Vi) / t,
Where Vf is your final velocity, Vi is your initial velocity, and t is the time traveled.
The question gives us that the helicopter moves from a starting velocity of 30 m/s to a final velocity of 40 m/s in the span of 5 seconds. This means we can fill in the variables to the equation, where
Vf = 40,
Vi = 30, and
t = 5.
Plug these known variables into the original equation, and we get
a = (Vf - Vi) / t = (40 - 30) / 5.
From here, the answer comes down to 10 / 5, or 2 m/s^2.
Hope this helps! If you have any questions, don't hesitate to ask :D
<span>The answer to this question would probably be "</span><span>D. The same background radiation was observed coming from all directions of space."
The background radiation here is referring to the Cosmic Microwave Background Radiation, one of the observational evidences of the Big Bang Theory which was discovered by Penzias and Wilson as they were doing some observations with a microwave receiver. </span>
