Answer:
This is the answer: The speed of a proton is about 5.0 × 10⁵ m/s
Explanation:
Because of the speeds of protons! :D
By definition, the speed of an object is given by:

Where,
dr/dt: derived from the position with respect to time
Therefore, speed has units of length over units of time.
Thus, speed is a derived quantity, since it depends on the value of two other quantities.
Answer:
a derived quantity is:
C. Speed
Heat equation, Q = m.c.Δt
Here, c represents " the specific heat of the substance "
Hope this helps!
1.5 / 0.5 = 3 I believe this is the right answer
