Answer:
The values is
Explanation:
From the question we are told that
The speed of the fire engine is
The frequency of the tone is
The speed of sound in air is
The beat frequency is mathematically represented as
Where is the frequency of sound heard by the people in the fire engine and is is mathematically evaluated as
substituting values
Thus
To determine what the cyclists average speed is, simply divide the distance the cyclist has travelled by the time the cyclist has traveled for.
Assuming that this is the average rate the cyclist is moving at it would be 12 km/hr.
You have to create table using cubic meters and the unit Kelvin to measure the temperature.
Answer:
0.00461031264 m/s
Explanation:
G = Gravitational constant = 6.67 × 10⁻¹¹ m³/kgs²
M = Mass of the Earth = 6 × 10²⁴ kg
r = Distance between Earth and Sun =
t = Time taken = 3 days
Acceleration is given by
Velocity of the star
The Sun's speed will be 0.00461031264 m/s
