This would be a cold front that forms when a warm air mass meets the area of a cooler air mass, although it should be noted that this doesn't always feel "cold".
ocean waves because its not artificial
Answer:
The maximum height the child can jump on the stick
h=0.459m
Explanation:
Energy conservation
Energy kinetic = Work
The energy the child do get the height jump is proportional at the distance and the consta can be compressed so:
Answer: a) 0.13*τ ; b) 2.08*τ
Explanation: In order to explain the discharg of a capacitor through a resistor, we have to consider the following:
Q(t)=Qo* exp(-t/τ) for a lose of 1/8-th of its charge
in this case, Q(t)=7/8*Qo=7/8*exp(-t/τ)
ln(7/8)*τ=-t
then, t= -ln(7/8)*τ =0.13
For a lose of 7/8 th of its charge , we have
Q(t)=1/7*Qo*exp(-t/τ)
t=-ln(1/8)*τ=2.08
