The truck has more KE than the bike
Explanation:
formula for force is:
force=mass × acceleration
but in case of friction
force =coefficient of friction × Normal Reaction
F. = u × R
U = F/R
but when placed horizontally
R= M×G
M=mass=60kg
G=Gravity(10m/s or 9.8m/s)
F=140N
U=140/60×10
U=140/600
U=0.2333333333
approximately to 3 significant figures
U=0.233
if i am correct rate it 5 star
Answer:
Following are the responses to these question:
Explanation:
Since the
is the current of ckt which depend on the reactance which inductor that also enables the ckt and inductor resistance
for capacities
for

When 
then
therefore,
remains at the same so, the maximum current remains the in same ckt.
