Answer:
25.2 m/s
Explanation:
∑F = ma
Nμ = m v² / r
mgμ = m v² / r
gμ = v² / r
(9.8 m/s²) (0.81) = v² / 80 m
v = 25.2 m/s
Answer:
Explanation:
From the question we are told that:
Wavelength
Length of cell arm
Refraction of air at at 1.00 atm pressure
Generally the equation for Number of shifts is mathematically given by
Since
Therefore
Answer:
Answer B
Explanation:
An increase in resistance makes it harder for the electric current to pass through
Answer:
1/5 km/min
Explanation:
the formula for velocity is distance/time
so if i plug in the distance and time i get 5/25 or 1/5
Hope this helps!
