Answer:
2. depends on both the wavelength and frequency of light.
Explanation: Speed of light(v)=wavelength×Frequency.
∴speed of light depends on both wavelength and frequency as shown from the equation above.
Answer:
The velocity of an object is the rate of change of its position with respect to a frame of reference, and is a function of time. Velocity is equivalent to a specification of an object's speed and direction of motion (e.g. 60 km/h to the north).
Explanation:
A chain position over a certain amount of time
Explanation:
i think you have to find the velocity by using its wight times the gravity of the earth times the distance it fell?
look in google for a formula the use these sign, w and g ,d
