The average time that it takes for the car to travel the first 0.25m is 2.23 s

The average time that it takes for the car to travel the first 0.25 m is given by:

t=\frac{2.24 s+2.21 s+2.23 s}{3}=2.227 s \sim 2.23 s

The average time to travel just between 0.25 m and 0.50 m is 0.90 s

First of all, we need to calculate the time the car takes in each trial to travel between 0.25 m and 0.50 m:

t_1 = 3.16 s - 2.24 s=0.92 s\\t_2 = 3.08 s- 2.21 s=0.87 s\\t_3 =3.15 s- 2.23 s=0.92 s

Then, the average time can be calculated as

t=\frac{0.92 s+0.87 s+0.92 s}{3}=0.90 s

Given the time taken to travel the second 0.25 m section, the velocity would be 0.28 m/s

The velocity of the car while travelling the second 0.25 m section is equal to the distance covered (0.25 m) divided by the average time (0.90 s):

v=\frac{d}{t}=\frac{0.25 m}{0.90 s}=0.28 m/s

Answer:

The average time that it takes for the car to travel the first 0.25m is  

2.23  s.

The average time to travel just between 0.25 m and 0.50 m is  

0.90  s.

Given the time taken to travel the second 0.25 m section, the velocity would be  

0.28  m/s.

The competitive exclusion principle states that _______.
nikdorinn [45]
<span>The competitive exclusion principle states that when two organisms attempt to fill the same niche, one will exclude the other from the ecosystem. Research partitioning is an adaptive evolution that when species are have similar preys, they compete with each other and one species is deemed to extinct in the process however if two species are of different preys, then they can exist with one another. To exist with one another, organisms belonging to a same species either compete for the resources or divide it amongst themselves. This concept is important because it helps in diversified ecology, where animals and plants of the same species co-exist and creates a beauty with nature.</span>

Find the wavelength of the balmer series spectral line corresponding to n = 15.
Anna71 [15]

Answer:

371.2 mm

Explanation:

The Balmer series of spectral lines is obtained from the formula

1/λ = R(1/2² -1/n²) where λ = wavelength, R = Rydberg's constant = 1.097 × 10⁷ m⁻¹

when n = 15

1/λ = 1.097 × 10⁷ m⁻¹(1/2² -1/15²)

    = 1.097 × 10⁷ m⁻¹(1/4 -1/225)

    = 1.097 × 10⁷ m⁻¹(0.25 - 0.0044)

    = 1.097 × 10⁷ m⁻¹ 0.245556

    = 2.693 10⁶ m⁻¹

So,

λ  = 1/2.693 10⁶ m⁻¹

    = 0.3712 10⁻⁶ m

    = 371.2 mm
