26. An ice-skater who weighs 200 N is gliding across the ice. If the force of friction is 4 N. what is the
1 answer:
Answer:
0.02
Explanation:
coefficient of kinetic friction = μ
force of friction = Ff
Normal Force = FN, but
FN = -W
Ff = -μFN
so μ = Ff/FN
= 4N/200N
= 0.02.

Answer:
Δh_air=714m
Explanation:
Given data
Solution
ΔP=P₁-P₂
=(ΔhHg)×pHg×g
=(Δh_air)× p_air ×g
Then
Δh_air=(pHg+ΔhHg)÷p_air
Δh_air=714m
Answer:
i'm pretty sure its B but i may be wrong if you dont wanna take the chance wait for someone
Explanation:
The answer is c) RNA contains uracil and ribose.
That will depend on the coefficient of friction between the sliding surfaces, and also on Zak's weight. We don't have any of that information.
950kg. It is W=mg. therefore, mass= W/g which is W/10
=9500/10
=950
