The maximum height reached is 45.92 m
Answer:
D = 25 miles
Explanation:
To solve this problem, we just need to know how much time it took both bicyclists to collide and that will be the same amount of time that the bee flew at 25miles per hour. With those values we could calculate the distance it traveled.
Since both bicyclists collide, we know that Xa=Xb, so:
Xa = V*t = 10*t and Xb = 20 - V*t = 20 - 10*t
10*t = 20 - 10*t Solving for t:
t = 1 hour Now we can calculate the distance for the bee:
D = Vbee * t = 25 * 1 = 25 miles
car starts from rest
![v_i = 0](https://tex.z-dn.net/?f=v_i%20%3D%200)
final speed attained by the car is
![v_f = 5 m/s](https://tex.z-dn.net/?f=v_f%20%3D%205%20m%2Fs)
acceleration of the car will be
![a = 3.6 m/s^2](https://tex.z-dn.net/?f=a%20%3D%203.6%20m%2Fs%5E2)
now the time to reach this final speed will be
![t = \frac{v_f - v_i}{a}](https://tex.z-dn.net/?f=t%20%3D%20%5Cfrac%7Bv_f%20-%20v_i%7D%7Ba%7D)
![t = \frac{5 - 0}{3.6}](https://tex.z-dn.net/?f=t%20%3D%20%5Cfrac%7B5%20-%200%7D%7B3.6%7D)
![t = 1.39 s](https://tex.z-dn.net/?f=t%20%3D%201.39%20s)
so it required 1.39 s to reach this final speed
Answer:
Mechanical waves are waves that require a medium. This means that they have to have some sort of matter to travel through. These waves travel when molecules in the medium collide with each other passing on energy. One example of a mechanical wave is sound.
The actual answer is B) Chlorine
According to the Bohr Model diagram, the atom has seventeen electrons. This makes it Chlorine.
