It shows deflection for the presence of current.However it can't be used for the A.C. current used at home.hope this helped.
If we assume that there is no friction between the tire and the ground, we can the use formula:
ΔKE + ΔPE = 0
where KE is the kinetic energy which is equal to 0.5mv²
and PE is the potential energy which is equal to mgh
Substituting the given values:
0.5 (10.5) (v2 - 2.10^2) + 10.5 (9.81) (8.59 - 22.4) = 0
Solving for v:
v = 16.59 m/s
Answer:
0.333 m/s
Explanation:
avg speed= (total distance)/(total time)
10m/30s
0.333 m/s
When potential energy <u>decreases</u>, kinetic energy increases.
