Answer:
(C) 15 Feet
Explanation:
You must park at lest 15 Feet away from a fire hydrant.
If you disobey this law, you could be fined up to $115 dollars.
Answer:
The answer is C because there is no friction there will be no friction force only applied and since its on ice you have to account for gravity

Answer:
Electric switch is commonly known as the key of an electric circuit.
Answer:
24.4 m
Explanation:
first we have to calculate how long the cat will be in the air, in vertical direction this is free fall from 4m (poor cat, hope he survived) with acceleration of g=9.81 m/s^2
time = sqrt ( 2 * height / g)
time = sqrt (2 * 4 / 9.81)
time = 0,903 s
then we know his horizontal flight was 22 m long, so ve can calculate verical speed
speed = length / time
speed = 22 m / 0,903 s
speed = 24.363 m
as you are asked to give 3 significant numbers answer is 24,4 m
When you look at this, you might not be sure which way to divide ...
Should you divide 6 by 5 or 5 by 6 ?
Here's a case where you can use your units to decide.
The question wants to know the 'period'. That's a length of time,
so the answer needs to have units of time.
If you divide 'cycles' be 'time', you'll get 'cycles/second'.
That's Hz. It's frequency, not time.
If you divide 'time' by 'cycles', you'll get 'seconds/cycle'.
That's time, and it's exactly the definition of 'period'.
Period = (6 seconds) / (5 cycles)
= (6 / 5) seconds/cycle
= 1.2 seconds
