Elizabeth noticed an increase of Mountain Bluebird sightings in her neighborhood. She wanted to know if there was an increase in

the population of the birds or if she was just noticing them more often because of recently learning their name while researching different species of birds. Match the processes Elizabeth used to answer her question to the step of the scientific method that it corresponds to.\

Answer:

Male Mountain Bluebirds are entirely bright blue above and duller blue-gray below, but this bird has hints of chestnut coloration on his underparts, reminiscent of Eastern and Western Bluebirds. His appearance matches descriptions of hybrids between Mountain Bluebirds and Eastern or Western Bluebirds. These mixed pairs have been recorded multiple times. Their offspring are also usually fertile, evidenced by successful nestings of hybrid adults with pure individuals.

Historical reports of mixed pairs have been most common between Mountain and Eastern Bluebirds, which are more closely related to each other than either is to Western Bluebirds. Many of these reports have come from where the ranges of Mountain and Eastern Bluebirds overlap — in the southern prairie provinces of Canada and the northern Great Plains states of the U.S. However, mixed pairs have been recorded in Nebraska, eastern Minnesota, and even southern Ontario, aided by the wanderlust of Mountain Bluebirds.

A body travels 30m in 5s, 45m in 7s and then 65m in the last 5s. Find the average speed of the body
JulijaS [17]
We can find the average speed of the body by finding the total distance covered, and then dividing it by the total time of the motion.

The total distance covered is:
S=30 m + 45m+65m=140 m

while the total time of the motion is
t=5 s+7s+5 s=17 s

So, the average speed of the body is:
v= \frac{S}{t}= \frac{140 m}{17 s}=8.24 m/s

A 0.43-kg object mass attached to a spring whose spring constant is 561 N/m executes simple harmonic motion. If its maximum spee
VLD [36.1K]

Answer:

0.22 m

Explanation:

m = 0.43 kg, K = 561 N/m

Vmax = 8 m/s

Let the amplitude of the oscillations be A.

The formula for the angular frequency of oscillation sis given by

\omega  = \sqrt{\frac{K}{m}}

\omega  = \sqrt{\frac{561}{0.43}}

ω = 36.1 rad/s

The formula for the maximum velocity is given by

Vmax = ω x A

A = Vmax / ω

A = 8 / 36.1 = 0.22 m
