A plane flying initially at 100 m/s uses an acceleration of 5 m/s² to reach a velocity of 150 m/s in 10 seconds.
<h3>What is acceleration?</h3>
Acceleration is the change in velocity over time.
A plane is flying initially at 100 m/s (u) and it accelerates to 150 m/s (v) in 10 s (t). We can calculate its acceleration using the following expression.
a = v - u / t = (150 m/s - 100 m/s) / 10 s = 5 m/s²
A plane flying initially at 100 m/s uses an acceleration of 5 m/s² to reach a velocity of 150 m/s in 10 seconds.

In electromagnetic waves, energy is transferred through vibrations of electric and magnetic fields. ... In sound waves, energy is transferred through vibration of air particles or particles of a solid through which the sound travels.
Answer:
It is easier to scale the voltage of AC from high to low and low to high than with DC
Explanation:
typically power is used far away from the place where it's generated so to ensure that transmission losses( copper losses) are minimized voltage has to be stepped up during transmission..but due to the fact that most house hold equipment requires low voltage levels it has to be stepped down once it reaches a household/ domestic load...it's easier to do this for Ac than for DC.
Explanation:
Formula to represent thrust is as follows.
F =
=
or, p =
F =
=
= 201.67 N
Thus, we can conclude that the thrust is 201.67 N.
Answer:
Option D. The average speed is 2.5 meters/second, and the average velocity is 0 meters/second.
Explanation:
we know that
To find out the average speed divide the total distance by the total time
Let
d -----> the total distance in meters
t -----> the time in seconds
s ----> the speed in meters per second
Remember that
we have
substitute
<u><em>Find out the average velocity</em></u>
To find out the average velocity divide the displacement) by the time
The displacement is the distance from the start point to the end point regardless of the route
In this problem
The start point is A and the end point is A
so
The displacement is equal to zero
therefore
The average velocity is 0 m/sec
