What is instantaneous acceleration?
2 answers:
Explanation:
Instantaneous acceleration is the acceleration at a particular instant. Mathematically, it is the first derivative of velocity, dv/dt.
Average acceleration, on the other hand, is the acceleration over a period of time. It is the change in velocity divided by the length of time, Δv/Δt.

Answer and method on photo
B. seems like the answer, I'm not sure.
Wavelength = velocity/frequency
wavelength = v/f
v= 13km/s = change this to m/s = 13000m/s
f= 14Hz
wavelength = 13000m/s÷14Hz =928.7 m
It’s hard to perfectly measure the distance something travels, as well as the exact time it takes, making the results have some variation.
R = 18 ohms
Explanation:
Given:
V = 36 volts
I = 2.0 A
R = ?
Use Ohm's law to solve for the resistance:
V = IR
or
R = V/I
= (36 volts)/(2.0 A)
= 18 ohms
