It will take you double the time, or 78 seconds.
They must equal 180°. Supplementary angles equal 180°
Step-by-step explanation:
Frequency of a mass-spring system is:
f = √(k/m) / (2π)
Given f = 2/π Hz and m = 20 kg:
2/π Hz = √(k / 20 kg) / (2π)
4 Hz = √(k / 20 kg)
16 s⁻² = k / 20 kg
k = 320 kg/s²
k = 320 N/m
If the 20 kg mass is replaced with an 80 kg mass, the frequency is:
f = √(320 kg/s² / 80 kg) / (2π)
f = √(4 s⁻²) / (2π)
f = 2 Hz / (2π)
f = 1/π Hz
Answer:
(-6,-4)
Step-by-step explanation:
Answer:
The biggest difference is between fruit juice and lemonade ($0.6).
Step-by-step explanation:
Giving the following information:
items:
fruit juice. $0.89
iced tea. $1.29
lemonade. $1.49
pretzel. $2.50
popcorn. $1.25
First, popcorn and pretzel are not beverages.
<u>Now, we need to find the differences in prices between each beverage and determine the greatest:</u>
Fruit juice to ice tea= 0.89 - $0.4
Fruit juice to lemonade= 0.89 - 1.49= $0.6
Ice tea to lemonade= 1.29 - 1.49= $0.2
The biggest difference is between fruit juice and lemonade ($0.6).
