Answer:
28.2 m
Explanation:
Applying,
Pythagoras theorem,
a² = b²+c²............... Equation 1
Where a = The distance from my starting point to my current point, b = distance walked due west, c = distance walked due south
From the question,
Given: b = 13 m, c = 25 m
Substitute these values into equation 1
a² = 13²+25²
a² = 169+625
a² = 794
a = √794
a = 28.18 m
a ≈ 28.2 m

Answer:
b
Explanation:
the ability for gases to compress is extremely helpful it allows tanks of oxygen to hold enough air for up to two hours and the strange thing about compression is that it allows some liquids to stay liquid at their boiling point allowing liquid nitrogen to stay liquid at room temperature
Answer:
The displacement of the elevator between 8 s and 24 s is 6 m.
Explanation:
Given that,
Initial time = 8 s
Final time = 24 s
We know that,
Displacement :
Displacement is the difference between initial position and final position.
In mathematically,
We need to calculate the displacement
Using formula of displacement
Put the value from graph
Hence, The displacement of the elevator between 8 s and 24 s is 6 m.
