Here is an example of how the three lines of defense are the same:
One situation in which force is created is when an object is moving and a force is created to stop that movement. Second situation is when an object is moving circularly and a force is created to move it towards the middle of the circle. The third situation is when a force is created that goes in the same direction as an object that is in movement.
The vehicle accelerates at 2.648 m/s².
We have:
Initial velocity, u = 50 miles per hour = 22.352 m/s
final velocity, v = 80 miles per hour = 35.762 m/s
Time, t = 5 seconds
The time in hours is:
t = 5 seconds
Now, the acceleration of the car can be calculated using the formula:
v = u + at
35.762 = 22.352 + a(5)
a(5) = 30
a = 2.682 m/s²
From the calculations above, the acceleration of the car is 2.682 m/s².

Answer:
19.33°C
Explanation:
To find the value of T you use the following formula:
v: speed of sound
To calculate v you use:
λ: wavelength = 0.651m
f: = 545Hz
by replacing :
Finally, by replacing in the first formula you obtain:
T = 19.33°C
