1000 miles = 1610km = 1.61x10^6m
2 weeks = 14 days = 14x24x1440
V=d/t = 1.61x10^6/14x24x1440
= 3.33m/s
Answer:
11.4 m/s
Explanation:
The expression for the Centripetal acceleration is :
Where, a is the accleration
v is the velocity around circumference of circle
R is radius of circle
In the given question,
a = g = Acceleration due to gravity as the car is at top =
v = ?
R = 13.2 m
So,
<u>v = 11.4 m/s</u>
Answer:
Frequency,
Explanation:
We have,
Speed of radio waves is
Wavelength of radio waves is
It is required to find the frequency of the radio waves. The speed of a wave is given by :
So, the frequency of the radio wave is .
