Answer:
-24.8 m/s
Step-by-step explanation:
Given:
y₀ = 60 m
y = 40 m
v₀ = 15 m/s
a = -9.8 m/s²
Find: v
There are three constant acceleration equations we can use:
y = y₀ + v₀ t + ½ at²
v = at + v₀
v² = v₀² + 2a(y − y₀)
We aren't given the time, so we need to use the third equation, which is independent of time:
v² = v₀² + 2a(y − y₀)
Plug in the values:
v² = (15 m/s)² + 2(-9.8 m/s²) (40 m − 60 m)
v² = 617 m²/s²
v ≈ ±24.8 m/s
Since the coin is on the way down, the velocity is negative. So v = -24.8 m/s.
To compare the answers, you need to have the same denominator.
We know that, 18 is a common denominator between 6 and 9.
(5/6)*3/3 => 15/18 (ALMONDS)
(7/9)*2/2 => 14/18 (CASHEWS)
As seen, the weight of almonds is 1/18 bigger than the cashews.
Hope I helped :)
Answer:
A) Based on the data, this is an example of correlation and causation.
Step-by-step explanation:
The correlating item is the sunlight
The causation is the growth vs. non growth: The sunlight caused growth. The lack of sunlight caused the plants not to grow as fast.
Answer:
A
Step-by-step explanation:
One way to see if two ratios are proportional is to write them as fractions and then reduce them. If the reduced fractions are the same, your ratios are proportional.
