Explanation: it seem right to me I really don't know if this right but I hope this helps
Answer:
<h3>The answer is 53.27 mi/hr</h3>
Explanation:
To find the velocity covered by the car we use the formula
where
d is the distance
t is the time
From the question
d = 554 miles
t = 10.4 hrs
We have
We have the final answer as
<h3>53.27 mi/hr</h3>
Hope this helps you
Light behaves like both waves and particles.
The speed that the person needs to leave the ground will be 4.32m/s
From the question given,
Height = 95cm
Since the person leave the ground v = 0m/s
acceleration due to gravity g = 9.8m/s²
Using the equation of motion
v² = u² + 2as
a = -g (upward motion)
s = h (distance changes to height)
The equation will become:
0² = u² - 2gh
0² = u² - 2(9.8)(0.95)
u² = 18.62
u = √18.62
u = 4.32
Hence the speed that the person needs to leave the ground will be 4.32m/s

Answer:
<h2>T(Period) = 1.33s</h2><h2>f(Frequency) = 0.75Hz (cycles/second)</h2>
Explanation:
